Toyota Auris owners – 12 volt flat batteries

Toyota Logo

As part of Toyota’s rigorous quality control programme, we have investigated the cause of a 12 volt flat battery issue that has left some Toyota Auris drivers unable to start their cars after only a short period without use, usually a couple of days.

We would like to apologise for any disappointment and inconvenience that may have occurred as a result of this issue. But we can now confirm that the cause has been identified and a permanent solution developed.

The following information only applies to any Toyota Auris (including Hybrid) produced between December 2012 and February 2014. If you have an Auris produced after February 2014 your vehicle is not affected by this issue. No other models are involved.

What causes the issue?

The issue is caused when the hazard switch is partially depressed for a very short period of time, incorrectly activating the car’s CAN-bus electrical communications system. This draws a constant flow of current that can discharge the 12 volt battery if the car is left unused for several days.

How can I prevent this from occurring?

Toyota has published a Technical Service Bulletin to its dealer network advising them of a permanent solution to this issue. The bulletin contains information and software files that will enable technicians to modify the software of the car’s combination meter. This update will prevent the incorrect activation of the CAN-bus system and prevent any potential flat battery concerns arising from this area of the vehicle.

If you still have concerns regarding the 12 volt battery of your current generation Toyota Auris then we recommend you get in touch with your nearest Toyota dealer for further assistance.

  1. I have a 2011 Auris Hybrid low mileage at 30k miles and my battery is also failing to start the engine. I did 60miles on Sunday and it would not start on Wednesday. The dashboard seems to go into melt down with all lights flashing.This has happened several times in the last few months. I replaced the battery in 2017. The Toyota dealer wants £120 to diagnose the problem and then who knows how much to fix it. This is now becoming an embarrassment to Toyota when they know there is a fundamental flaw with the electronics and they are ripping off their customer to get it repaired. Do the right thing Toyota and recall the Auris because the problem is obviously bigger than the years of the model you have identified

      1. Hi Terry,
        Thanks for getting back in touch with us.
        We have checked with our customer relations team and can see that an email was sent to you on 07/08/2020 at 16:37 with advice from our team.
        We would recommend checking your spam or junk email folders for this, but if you cannot find it we can ask our team to re-send.

    1. I have recently taken ownership of a 2014 Auris and an seeking to clarify the position with battery failure as a result of hazard light use. Customer services seem unaware of the problem and have referred me to Toyota dealer. Arnold Clark in Ayr with whom the car has a full service history have acknowledged my inquiry and I await a reply.

      It would be good to know the precise reference for the Technical Service bulletin with regard to this problem and protocol for remedy. It would be good to know exactly the extent if this problem.

      I’ll let you know if there is any progress.

      1. Hi Hugh,
        Thanks for your comment.
        We can see that you’ve been in touch with our Customer Relations team and would recommend addressing this issue in further detail with them and your dealer as they are best placed to assist you further.

  2. It recently happened to my low mileage Auris 61 reg as well during lockdown, I got shocked when see so many customers had the same issue recently, and also to see that even after buying replacing new battery, it can be an ongoing problem. in addition, paying £138 for diagnosis plus even spending more on reprogramming electrical communications system, known since 2014, at local Toyota centre seems to be the only solution suggested in this blog by Toyota correspondence.

    Based on the article above only some vehicles are affected and recalled. however, from the comments
    it sounds it may also affected to others as well. so why there isn’t a recall with free reprogramming for everyone affected?

    anyway, do you suggest me to take it to local Toyota centre, get it reprogrammed and use my old battery (it was working with no problem until last week), or just buy a new battery and replace it (sinse the article says my car is not amongst the affected one)?

    1. Hi Sam,

      Thanks for getting in touch. The blog post above details a specific issue that impacted Auris vehicles produced between December 2012 and February 2014. No other models are involved.

      Recently, during lockdown some owners have been experiencing battery problems. Of course, without being able to assess the cars ourselves we can’t confirm the exact causes for any issues, however we do know that infrequent use combined with short journeys can sometimes not give the 12 volt battery time to fully charge – which can then leave owners unable to start their cars.

      In your case, as we can’t look over your car we recommend contacting your nearest Toyota centre as they are best placed to run a diagnosis and make any necessary recommendations. You can find your nearest dealer, here:

      In addition, for future reference if you are leaving your car for a particularly extended time, we do have advice you can follow:


  3. We have had similar problems with our 2017 (!) Auris, even though we run it regularly to recharge the battery! This is ridiculous for such a new car! What are we supposed to do?!?

    1. Hi Bea,

      Thanks for getting in touch with us. We’re sorry to hear you’re experiencing issues with your Auris.

      1. Hi,

        My Auris ’13 is doing the same, I’ve taken it into the Toyota dealership and they told me it was my battery, however this is a new battery. It seems all they wanted was for me to spend another £170 on a new battery. I proceeded to taking my car to Halfords for a battery test and they have told me my battery is working just fine.

        This is the third battery my car has had in as many years. It’s becoming expensive and frustrating.

        1. Hi Zainul,

          Thanks for getting in touch with us. We are really sorry to hear about this. If you are unhappy with your experience with your Toyota centre, we would recommend contacting our customer relations team to discuss this further. You can find our team’s contact details here:


  4. My May’14 Auris’ battery has gone flat after a few days of not being used. It happened first time a month into lockdown when my driving reduced to weekly chores and shopping trips. I have had to buy an expensive battery charger and that got the car started. I was then starting car every few days to keep the battery charged. However, now the battery has again gone dead and the battery charger has failed to charge the battery.

    This vehicle is serviced annually and I am a low mileage driver.

    None of the online sites I have checked provide Start/Stop battery fitting at home. Toyota dealership doesn’t seem to pickup the phone.

    it seems to be a known problem with Toyota battery. How do I get this fixed. I cannot be locked in house without a car during lockdown. I am very frustrated with this situation.

      1. My In Laws in their 80’s have been locked down and of course their 63 reg Auris battery is completely dead. The AA replaced the battery but that also now dead. What a ridiculous thing for a car of tis age to not hold charge for any period of time.

  5. Hi – I have been asked by my RAC home side assistance to replace the battery. They came after a dead battery issue & had run my engine for about 4-5 mins. When they started running the engine, the batter output was 4v it seems. Then, they showed me a diagnostics tool to show the voltage was 10.7 after 4-5 mins of running the engine. Their diagnostics said “REPLACE” and asked me to replace the battery. I have no idea, does charging for 5 mins, giving output at 10.7 v means I have no option than replace the battery ? I know its hard to diagnose, any advice welcome..

  6. Hi i have a 2012 Toyota auris and have come to experience this fault as i have rarely driven the car during this COVID-19 lockdown. I have already spoken with my dealership and have the car booked in to be looked at but at my own cost of £136. Given this is a known manufacture fault why am i being charged £136 for it to just be looked at? i was told it was due to my car being out of warranty but this isn’t my fault….. my husband has a yaris which was recalled due to a airbag issue and he wasn’t charged. so can you please advise why i am to be charged for a fault that Toyota has known for the past 6 years!!!!

  7. Hello, I have a January 2013 Auris and this is becoming a real problem, I am constantly worried about the car starting and have already replaced the battery. I am using the car weekly currently but it wouldn’t start Saturday, I only replaced the battery 4 months ago. Please can you help as it is currently at home unable to start.

    1. Hi Lisa,

  8. My Feb ’14 Auris’ battery is now draining continually.

    I am really frustrated with this vehicle. Its catalytic converter was stolen twice and I had to pay to have a catloc fitted.

    Now I can’t trust it to start and have had to buy a battery charger. Now I find that this may be a known problem. I can’t keep.calling out a rescue service (I have had to have more call outs with this vehicle in the last year than I have had with all my other vehicles combined) and I need a working vehicle to care for my elderly mother.

    How, during lockdown do i resolve the battery problem.

  9. My Feb ’14 Auris’ battery is now going flat after a couple of days of not being used. I have had a rescue service out twice and have had to buy an expensive battery charger. I need my vehicle as I need to be able to reach my elderly mother during lockdown.

    Very frustrated with this vehicle; after its catalytic converter stolen twice I have had to pay to have a catloc installed, and now I have to buy and carry around a battery charger. I never have any confidence that it will start when I need it.

    How do I get the battery problem sorted during lockdown?

  10. Hi there, we own a 65 plate Auris hybrid, the 12v battery died today, no rhyme or reason, the car was only MOT’d and serviced by RRG Toyota Bradford. It was used yesterday for a 30 mile drive (my wife is a key worker) we had to jump start the car this morning but now the keyfob doesn’t work. Is there a way to fix this?

    1. Hi Lee,

      Thanks for getting in touch with us and we are sorry for our delayed response. In this case we would recommend discussing this further with RRG Toyota Bradford as they are best placed to help you further. We will email you directly in order to gain additional details and put the centre in touch with you directly.


  11. I have come to this site today to check this problem out and am horrified to see this problem has been known since 2014 and nothing appears to have been done about.
    For the second time during ‘lockdown’ I have had to get AA out through Toyota Breakdown as the car wouldn’t start when we have gone out to collect our shopping. Today the AA told me I’d need a new battery and charged £280 for this . We are pensioners and this was quite a shock

      1. Hi there, we own a 65 plate Auris hybrid and the 12v battery died today, the car was serviced and MOT’d by RRG Toyota Bradford a couple of months ago and the car itself was only used yesterday for a 30 mile drive (my wife is a key worker) I had to jump start the car today and now the keyfob no longer works. Is there a way to fix this and should the 12v be checked during a service and MOT?
        Look forward to your reply.

    1. My daughter’s five year old Toyota Yaris has a flat battery. After initially getting the electrics to come on by jump leads to another Toyota which was working ok, and attempting to turn over the engine, the radio screen came on to show a bar which was filling left to right indicating an update or initialisation. The car will now not even show the original electrical connection. What to do?

      1. Hi Sean,

        Thanks for getting in touch. We’re sorry to hear about the issue you’re experiencing with your daughter’s Yaris. In this case, we would recommend contacting your nearest Toyota centre as they are best placed to offer further advice. We will email you directly in order to gain additional details and put you in touch with them directly.


  12. I am having the same problem with my 2011 Auris hybrid. It struggle to start if I don’t drive it for a couple of days.

    1. Hi Mubashir,

      Thanks for getting in touch. We’re sorry to hear about the issue your experiencing. We do have some hybrid storage advice that we hope will help.

      In addition to the storage tips for our conventionally-powered vehicles, our hybrids require additional steps for each battery, as the hybrid vehicle battery and auxiliary battery will discharge and their condition is liable to decline.

      To prevent excessive auxiliary battery drainage, charge the battery at least once every two weeks by powering on the hybrid system for 20 minutes with all non-essential electrical accessories (such as air conditioning and audio equipment) turned off. It is not necessary to drive the vehicle, but do not start the hybrid system in an enclosed area unless the tail pipe is connected to an exhaust hose to prevent harmful buildup of fumes. As an alternative, you may disconnect the negative terminal of the auxiliary battery.

      For the hybrid vehicle battery, charge the battery at least once every two months by starting the hybrid system for about 30 minutes*. Check that the “ready” light is on and all lights and electrical accessories are off. As with the auxiliary battery charging, it is not necessary to drive the vehicle, but the steps to prevent exhaust buildup must be taken.

      Alternatively, our Toyota centres do remain contactable by phone and email during this period if you wish to discuss this further. You can find your nearest centre via this link:


    2. Hi after calling out the AA because my Auris Excell wouldn’t start they recharged the small battery in the boot it & all was ok.They told me to turn the car over / leave running for 10 mins each day which I did but attempting on the 6th day after he had been it would not start/couldn’t lock it/dead as a dodo😞.Because of this virus contacted a lady at Bentley Toyota who told me to find a place (motor world) open & to get a new battery from them/get it fitted.This I did & you know….it works great now.My contract service comes up in June at Bentleys WARRINGTON & I will ask them to check things over during the electrical check & rectify the C bus problem on the haz warning button which has drained the old battery initially.Thank you to the lady I spoke to at Bentley for those very wise words!!ToyotaFender🤪

  13. I have a 2014 low mileage Auris Estate Hybrid. We have owned it for two years and have been unable to start it about 8 times. We have had to buy a £60 jumpstart device and keep it in the car.

      1. Hi Eric and Toyota
        We have a 13 plate Auris hybrid which we purchased 3 years ago and have experienced exactly the same flat battery problem on 5 occasions, the latest of which was this morning when we needed to go shopping for food in the middle of the lock down. The car had been standing on the drive for 3 days. It was serviced and mot’d a week ago and our dealer was asked to check the battery yet again. It was given a clean bill of health!

        We are pensioners who live in a rural area and are now stranded in the middle of a national emergency. Toyota, you have obviously been aware of this problem for several years but have failed to solve it. Shame on you! I think this would make a good story for the national press in the current circumstances. What do you think?

        1. Hi Jim,

          Thanks for getting in touch. We’re really sorry to hear about this and would like to help you further. We will email you directly in order to gain additional details and put you in touch with our customer relations team who are best placed to discuss your situation with you in more detail.


        2. Hi Toyota
          Thanks for your prompt response. Our local dealer came out yesterday, took the car away, replaced the battery and returned it before 5.00pm. Many thanks Alexander Wallace. However, it did cost me £145. I hope this solves the problem! If it doesn’t I shall be taking this further. I have been told that it is possible to remove a fuse to stop the battery draining. Can anyone tell me which fuse to remove? Our dealer promised to email photos but have not done so and are now closed for 3 weeks during the lock down.

          1. Hi Jim,

            Thanks for getting back in touch. We’re glad to hear it’s been sorted. We’ve just spoken to your dealer and the photos will be sent over as soon as possible. We’re sorry for the delay.


  14. Hi, I’ve got a 2016 Auris Hybrid and keep having a problem with my 12-volt battery discharging. Its gone three times this year; twice when left for 7 days at the airport and one after 2 days. Is anyone else having these issues? I’ve had it back in for checking at the Toyota garage but they say its fine and have advised me to unplug the battery when I’m not using it – no exactly practical or helpful!

    1. Hi Fiona,

      Thanks for getting in touch. We will email you directly in order to gain additional details and put you in touch with our customer relations team who will be able to help you further.


      1. I’ve had this problem again, only 7 weeks after the last check on the battery by the dealers. The car hasn’t been used for 3 days, but no sign of a problem before this. Its becoming very frustrating to keep getting told there is no problem only for it to keep draining.

      2. Hi Fiona

        Did you get this sorted? Was it expensive?

        I have a similar problem with my March 2013 Auris. I drove the cr yesterdy and parked it on my drive at 15.00. At 19.30 I went to the car but it would not stop, everything died and I could not even lock the doors.

  15. My 2013 Auris has this problem, with the battery draining when left for more than a few days. I took it to the local dealer who investigated and said it’s not caused by this and I needed a bigger battery which they got for me. The problem still happens and the dealership deny it is a problem.

    1. Hi Diane,

      Thanks for your message. We’re sorry to hear about what you’re experiencing with your Auris and have emailed you to gain additional information. This will allow us to open a customer relations case on your behalf in order to investigate this further.


  16. I also have the same problem with my 11 ref Auris Hybrid, where the car won’t start sometimes. I have to switch it off again, and switch anything else off (lights, fan, radio) before trying again. This seems to work, but there may be a time where it won’t work.

    I appreciate that a 12v battery won’t last forever, but this does seem to be a fault wider than the published models. Out of interest, with the advent of start/stop batteries available, would it be better to replace the 12v battery with one of those?

    Please advise, as one day I’ll be stuck whilst trying to pick up my children or going to work!

    1. Hi Shona,

      Thanks for getting in touch. Without assessing the car ourselves we are unable to provide an effective solution. We would recommend taking your Auris to your nearest dealer as they will be best equipped to assess the car in person and make the best recommendation.

      Hope this helps.

  17. My wife has a 64 reg Auris and the battery went flat while we were in Australia last year although my brother-in-law was driving it every couple of weeks. We are back in Australia and the same has happened again. What if we wanted to leave the car at an airport while we stayed away for about 3 weeks? Not good enough Toyota!

  18. Just spoke with the my local dealer who said that this is not correct about the battery going flat.

  19. I have an Toyota auris 63 plate and have the same problem with a flat battery when I finished work yesterday. AA came out and said get a new battery. If Toyota knew about this fault since 2014 while have I not been told. Now got to wait as No one appears to hold these battery in stock. Now I have to pay £125 for a new battery as a nurse I need my car. Can you please tell me why we were not informed about this fault.

  20. Hi All,

    Wow this is a common area for problems. I have 2011 auris hybrid, 50k miles. Has been good generally but developed a problem recently which is that when I press the on button all the warning lights come on but the green ‘ready’ light does not.

    Garage have informed me the startup battery needs replacing, which is fine, and expected every now and then, but wanted to ask anyway:

    1) As an alternative approach, whenever I pressed and held down the on button for several seconds, with foot on brake, the green ready button always did eventually come on. I did it like this a couple of times and it always worked. Ie. holding down *until* it comes on. Does anyone know whether this is a valid way to make the car start up, or indeed whether it is a bad idea for some reason? I know the standard approach is to press it once and release.

    2) I think it might also be useful to depress the brake and wait a few seconds before pressing the on button. Anyone know about this?

    2) Does anyone know whether solar-powered trickle chargers are ok for my car, and which one to get if so? I do quite a few short journies which I would certainly expect to make this problem worse, perhaps also because they are so short that much of them is done via electric power.

    Thank you!!!!

    1. Hi Noel,

      Thanks for getting in touch and we are sorry to hear that you are experiencing these issues. If you could please provide a VIN number, we will be able to assist you further.


        1. Thank you, Noel. A VIN number will allow our Technical Team to assist you in more depth, however if you can’t provide it, we will of course get back to you with what we can.


          1. Hi Noel,

            Once your startup battery has been replaced as advised by your local Centre, your vehicle should start up as expected without the need for an alternative approach as you have mentioned. Generally trickle chargers ensure the battery is topped up during an extended period of inactivity, therefore should only be used if you are leaving your vehicle for prolonged periods of time (i.e. a number of weeks or months). Thanks.

  21. Hi,

    I have 2016 Auris Hybrid . I am unable too stay my car .I can see a message “12v battery low check manual” on my dash board. After looking at comments I understand this is a common problem . Does the 12 v battery charge up from hybrid battery. I do daily short trips . Travel around 6 miles a day , uses heating due to winter which might dry the battery but I can’t expect the fact that I am not able to start the car having spent so much on hybrid battery car. what do u suggest ?

    1. Hi Jagadeesh,

      Thanks for getting in touch. We would recommend contacting your local Toyota Centre who will be best equipped to advise you further and arrange a possible inspection of the vehicle.


  22. My dad bought a 2016 Auris around ten months ago and has had recurring problems with it running flat since. Happened again yesterday, just days after previous use, and just over a week since it was left running for the specific purpose of charging the battery (on the advice of the AA callout guy who makes frequent visits). Is this due to a fault? The dealer ran a diagnostic and concluded the car was fine. My dad is therefore exceptionally frustrated and disappointed with the car, and unless the issue can be resolved, will look to returning the vehicle and going with a different manufacturer. This would be such a shame as it’s otherwise a lovely vehicle.

    1. Hi Rachel,

      Thanks for getting in touch.

      If there is an underlying fault which is causing the battery to go flat, then this needs to be diagnosed by your Toyota Centre. The battery should be tested with a suitable tester, such as the Midtronics model, which Toyota Centres will be using. This will determine if the battery is defective or if it requires a recharge before testing again.

      Another test that can be carried out is a battery drain test. This will assess how much current is being drawn when the vehicle has been locked, allowing for electronic consumers to shut down. If the current drain on the battery is excessive, this will cause it to discharge and become flat quicker than normal.

      The biggest cause of flat batteries is often attributed to driving profile and the ambient temperature. This will affect all manufacturers, since it is a natural phenomenon. When the ambient temperature lowers, the rate of discharge increases. This is often why many people report flat battery issues in winter and colder temperatures. Also, if a driver carries out a lot of short journeys, starting and stopping the engine frequently without completing an adequate driving cycle, this will have a negative effect on the battery’s state of charge, since it will not allow the battery to charge fully whilst the engine is running and the highest amount of current is consumed during starting.

      We suggest you have the battery and charging circuits checked by your nearest Toyota Centre to ensure they are not defective. If the vehicle is being left unused for long periods of time or is carrying out frequent short journeys then a trickle battery charger is worth a consideration.

      We hope this helps.

      1. Thanks for this. The AA came again last week and got it started and confirmed that there was no excessive drain on the battery and that the charging system was working. We then ran the engine for about 90 minutes and took the car for a 15 min drive. Car Genie now says the battery is healthy. So no technical fault; just not driving enough. And yes, short journeys (as in the week before) take more out of the battery than gets put back.

        We got the same comments when phoning Toyota but am awaiting a response from their technical support team about using a battery charger to trickle charge the battery. The AA man suggested that this would be OK, though Toyota (Kingston) said don’t do it. Interesting that you positively suggest using a battery charger.

        If nothing actually wrong with the car, then just an unacceptable design fault that requires more driving than we need to do (negating its environmental credentials), with no means of charging a flat battery other than an AA call out. The claim by Toyota that this is the same for any car is disingenuous. The rate of discharge is much higher, plus not being able to use a battery charger (apparently).

        1. We apologise for the inconsistencies in the information that you have been given. If you could please provide a reg or VIN number then our technical team can investigate this further and liaise with Toyota Kingston. Following on from that, we would suggest for you to take your vehicle back to them for further examination.


  23. I have a toyota Auris 1.33VVTI TR 59 Plate , Start/ Stop. For some reaosn- the Fan comes on after the car is swirtched off. Battery is drained and the car will not start. Delers have had a look at it and they said the ECU is faulty , this has been replaced and agian after a cuple of week, same problems had occured.

    Dealers have said that they have replaced 2 ECU – One main and teh otjher for Start/ stop.

    There is a TOYOTA BUlletin about Hazards lights casuing a fault and darining the abttery./ Not sure taht Dealers are checking ?


    1. Hi Vic,
      Thanks for getting in touch.
      There is a known concern about the Hazard Lights draining the 12V battery. However, this issue is experienced on current Gen Auris (produced from 2012 onwards). Therefore, this vehicle is not affected by this issue.
      There is also a Service Bulletin relating to the Stop & Start ECU; however, this Bulletin includes a flow chart and diagnostic process the technician needs to follow and may not necessarily imply that there is a defect with the vehicle.
      Finally, the issue needs to be further investigated. One thing which is for sure is the fact that vehicles with Stop & Start systems require the use of a special (heavy duty type) 12V battery. Maybe this could be the starting point of the investigation. However, we would not be able to carry out diagnosis over the blog. Therefore, we’d advise taking the vehicle to your local dealer for further investigation.
      Hope this helps.

  24. My mother has a 2011 Auris Hybrid, bought after my father died as a reliable town car. It has this problem of failing to start, the AA came out, they jumped it no problem, checked the 12v battery it was found to be good and charging well with little or no drain when everything shut down and key moved away from car. a month later it reoccurred after not driving car for 2 days and was taken to Toyota who tested the battery and could find no fault. After Christmas this year it has started doing it again. Once again the AA came out and started the car, tested it and could not find a fault. Yesterday I took it to Toyota who phoned me today to tell me they cannot find a fault. I have told them keep the car for 2 days and try again. No problem but if we need to run diagnostics it is £117/hour plus vat.
    This is on a 7 year old car with less that 32,000 miles bought from Toyota!

      1. I got a call from Snows Toyota at 18:10 to late to talk to the customer relations team.
        They have told me they can find no fault with the car, they have had it since Monday but claim everything is OK. So why have we had to have the AA out twice for the same fault.

        1. Hi John,
          We’d advice contacting Customer Relations on this number: 0344 701 6202. Similarly, if it is more convenient, we could get them to contact you. If you’d like us to contact them please could you provide us with your full name and car registration and will pass that over along with your email address. Thanks.

  25. I just had a flat battery issue with my 2013 Toyota Auris after it was not driven for a week. Charge it up, then can’t start engine. I kept trying, and finally got it fired up after more than 10 attempts. I bought Toyota only for its claimed reliability. Now, I have experienced brake problem, flat battery and engine difficult to start within a short period of time, plus painful experiences with Toyota dealer in trying to repair the fault, I would rate Toyota no better than average car in terms of reliability. Having said that, Toyota is very keen to chase you up to service your car with premium charge. With 10k miles service interval, any car on the market can do better than Toyota.

  26. I have a 2014 Auris Hybrid Estate, which other than a few niggles, I am generally very pleased with.
    I experienced my first flat 12 volt battery experience last Sept 16, outside a B&Q branch late on a Sunday.
    The Toyota help line if I had to rate it I would award 3 out of 5 stars, and in frustration I called the AA who arrived within a 1/2 hour.
    The car was running within 5 minutes, and the technician then removed the rear floor and did a number of tests on the battery, charging rate and confirmed it was OK but low so keep it running.
    He also told me that this was a well known problem, not only to Toyota but also the AA.
    He said his personal opinion was that the battery was too small particularly when doing local commutes. He advised that to help matters, the luggage space bulb should be removed and that the interior lights should be kept permanently off.
    Early next morning I went to the local Toyota dealer and the electrician checked the car and said everything looked OK. However he swapped the battery for a service battery and said to come back in about 5 hours.
    On return he replaced my battery, now fully charged, and told me that to avoid this problem when waiting in the car, unless the engine is running, turn off the radio, heating fan and auto lights.
    He also said there was a larger battery available on the aftermarket, 65A/h which he had fitted successfully to customers cars. He said that as a dealer he knows this works but Toyota don’t want to know. He added that in his opinion the 5 amp charging rate was too low for a commuting car.
    With all this in mind I have been very careful to follow the advice, but after a short run this morning to the shops, on return I left the car in the drive and at 4pm, again planning to go out, the car is dead.
    Toyota are collecting in the morning!!
    Also I will be fitting the big battery, but why this widely known problem cannot be acknowledged and fixed by Toyota is a mystery to me !!
    Sorry Toyota, but the new Prius is now out of the question !

    1. Hi George,
      We’re so sorry to hear that you’ve been experiencing issues with your battery. Have you spoken to our customer relations team about this? They may be able to help.

    2. Hi, I was wondering if you are still experiencing problems with your battery going flat.

      I am in the process of buying either a used Toyota Auris 2014 Hybrid Estate or a Skoda 1.2 petrol Octavia.

      As I understand it the battery problem is on Toyota Auris’ registered between December 2012 and February 2014.

      The Toyota I am looking at is registered March 2014 so hopefully would not have those battery problems.

      However, I am a little concerned that a problem with the battery might develop some time in the future.

    3. Hi – I own an Auris (2010\2011)
      I constantly get the flat battery issue even though I am extra careful not to leave anything on.
      Can you please confirm that this issue and associated software fix is NOT related to my model.

      Toyota Auris 2010
      Hybrid / 1.8L petrol (136hp)
      continuously variable transmission (2WD)

      1. Hi Chris,
        Thank you for getting in touch. We’d recommend going to your local dealer, as they would be in the best position to review the car and advise you. Many thanks.

    4. I have had this issue flagged up as i previously left a comment about the battery going flat issue, a year ago.
      This issue is definitely not confined to pre-2014 Auris. My Hybrid, from 2015 has now left me with a flat battery after two extended holidays, in one case after three weeks not driving, and this summer, after 5 weeks.
      Each time, the emergency service which came to get me going again expressed the opinion that the battery is too small for the car.
      My dealer who, in every other respect are marvellous just blithely say that if I go away for more than 2 weeks, I need to disconnect the battery.
      I think that is totally unacceptable for a two year old car. What is the point of a new car which is unreliable?
      Toyota need to sort this out more satisfactorily.
      Janet Ollier

      1. Hi Janet,
        Thank you for your comment and sorry for the delay. It should be noted that any vehicle, if left unused for a period of time, will suffer a flat 12 V Battery. We agree with your dealers comments, regarding disconnecting the battery if the vehicle remains unused for a period over 2 weeks. To add to this, if the vehicle is garaged whilst the you are on holiday, you can use a trickle charger in order to keep the vehicle’s 12V battery full charged.
        In order to provide peace of mind your dealer can also carry out a test to the battery.
        Hope this helps.

  27. I brought Mine back in May 2013 when the model came out, by August i had experienced 2 flat batteries after not using the car for 1 day, each time i got it jump started and took it to Toyota garage who couldn’t find a problem with it. I ended up contacting customer services after it happened the 2nd time. After the 2nd time I was phoned up by the garage and told they couldnt find a problem with it and wanted to give me my car back, i emailed back customer services to inform them that it was not acceptable that i owned a £24,000 car which was less reliable than my brothers £400 banger… i then got a phone call an hour later from the garage saying they putting a new battery in the car.

    Since then i never had an issue, i had the car sent in to sort out the issue this article mentioned so i can contest that its not been an ongoing issue… Except this morning when my girlfriend kindly started my car up thinking it would defrost it

    I came out 30 minutes later and all the lights were blinking and i couldn’t get it to start, its now dead again and am waiting for a jump start.

    Sadly she had just pushed the power button to start the electrics but not the engine, so the car had drained the battery with the lights and AC heaters on.

  28. I found out that the battery on my Toyota Auris Hybrid that battery was flat yesterday. When I pushed the start button, the dash lights and radio went into a flashing on/off mode., but the headlights wouldn’t come on. I had a new battery fitted, and although all the lights now came on, the engine did not start. I am now stuck with a 6 year old car that wont go anywere.
    I had a Toyota Corolla before this one and I didn’t have any trouble with it in the 7 years I had it

      1. No I didn’t as the car was not driveable, and had to ask a local mechanic to get it for me. The car is now at the local Toyota garage, as I had to organise a recovery vehicle to transport it for me.
        My wife is now very dubious about keeping the car now.

        1. Hi Rob,
          Thanks for getting back to us. We would have to advise you to keep in close contact with your Toyota Centre. They will be able to advise you and reassure you on your situation. Many thanks 🙂

    1. I have noticed a similar issue – flashing radio lights etc. My Auris is 5.5 year old. I could not start the car, but did manage to do it after 2-3minutes. Another time, after 4 days the car did not have this problem, so was not sure what is wrong. a week later, again could not start the car…
      I am not sure what is wrong, as I thought there should be a message on the dashboard if the battery is gone. has anyone know the answer to this problem?

  29. I am the owner of a 2013 Oct Auris HSD which has suffered from a flat 12 v battery on a number of times (3 or 4). Yesterday (02/07/2016) evening was the latest. I had been cleaning the interior of the car which was a bit dirty the car having been used to transport rubbish to the nearby recycling centre. Afterwards I had gone to pick up my 3 year old grandson from his aunt’s house which is on a main road. Left the car for a couple of minutes before which I put the hazard lights on. Returned home and left the car on the entrance to my drive way as we were about to go out. Came out to start it up only to find the car dead. I couldn’t switch it on, get into the boot or operate the remote locking (had to use the manual key). The car was blocking my wife’s car in so we couldn’t use that and also made it difficult for the neighbour to get in/out of his drive.

    Seriously considering geting rid of this rather expensive piece of hardware/software. After the experiences I have had and after reading the experiences of others I am not sure I would go for a Toyota HSD again.

    1. Hi Peter,
      Thanks for your post. We’re really sorry to hear you are having problems and we want to help resolve them for you. We would advise contacting our customer relations team. They can help advise and assist further. Many thanks.

      1. I contacted Vantage Toyota where they arranged for a test on the battery and found it to be 70% charged. I found this surprising being that the battery had been on charge all night and I had a 56mile run in the car mainly on motorways. They arranged for the 12v battery to be replaced for which I am grateful. It is too early to say whether it has cured the problem. Just let’s hope so.

    2. I have been considering the purchase of a new Auris Hybrid Business Edition but have been very put off by the battery problems as typically I leave my car unattended for two months in the summer and a week or two at other time. As a result It seems this car is not for me.

      Or have the problems been solved in the latest version.

      Incidentally what is an HSD?

      Christopher Singer

      1. Hi Christopher. HSD stands for Hybrid Synergy Drive, the technical term for our hybrid cars. The Auris has since undergone a facelift and we have had no reports of this incident happening again. Have you taken a test drive yet?

        1. And I should have added and yes taken on a test drive and impressed – and go back to the show room in a few minutes!

          1. That’s great news Christopher! We hope you get on well, and please don’t hesitate to get in touch with us if you have any further questions :).

      2. Personally I wouldn’t leave the Auris HSD for 2 months. I have no experience of leaving mine for that length of time but I would be a bit concerned about doing so.

    3. I too have just experienced a flat battery on a 2015 Toyota Auris Hybrid, after being away and not driving it for 3 weeks. It does not seem to be recharging very well now and I feel vulnerable with the dark nights.
      The comment about using the hazard lights throws some light asI had used them briefly just before Zi went away.
      After having to get Green Flag out to get me going, I went Tony local Toyotagarage. They assured me all was well and did not mention this problem. Looks like another trip is required.

      1. After my Toyota garage replaced my 12v battery I have had no problem. But I don’t leave it with the doors open, i.e. with interior lights on.

    1. i am in the same boat flat battery after leaving for more than a couple of days – this car is obviously not fit for purpose – i have to jump start the car regularly – toyota appear uninterested and offer no solutions denying that this is a problem – hazards also have a tendency to go off setting off alarm – the 12v battery is obviously not up to the job and requires a higher amperage – a solution that tells me me to drive the car more is not a solution and a modern car should be able to be left for more than a couple of weeks without draining the battery to such an extent that mechanical locks have to be used to enter car

      1. Hi John. Thanks for getting in touch, and sorry to hear you’re having issues with your vehicle. Have you spoken to your dealer about the issues you are experiencing?

      2. I see the main problem as Toyota leaving dealerships either totally in the dark or else giving bad or incorrect advice, as per several instances here. My dealership had never experienced the weird set of faults exhibited by a faulty battery and took two weeks to realize what the problem was. For most of that time they thought I was making it up.

        I looked at the tiny battery in mine. It looks like there is room for a larger battery, though no doubt the clamp won’t fit one. I suppose having a small battery to charge means an improvement in fuel figures, either that or someone got their calculations wildly wrong.

        1. Thanks for the feedback Michael. Any issue may or may not be caused by the same things. We try to ensure our dealers are as informed as possible when it comes to car issues, hence the thorough training our centre staff are given. However, we have resources such as the blog and our customer service channels to ensure that, if an answer isn’t satisfactory, we can investigate further.

  30. We recently had the Auris hybrid recall software update. We had problems starting the car, after pushing the big button the warning lights all came on and sometimes we had to repeat the procedure ten times before the car would go to ready mode. It would then drive fine except that dab would cut out after a few minutes and the tailgate would be locked on stopping the car.

    After the recall fix, the car was fine for two days but then exhibited the same problems again. As it was due for a service, Burrows Sheffield said they would investigate, but after ten days of starting the car have had no problems until yesterday, when they said it would not start because the battery was flat.

    My question is, could my symptoms have been consistent with a flat battery? What exactly happens when you try to start a hybrid with a flat battery? The car is still with Burrows but until yesterday they have denied there being any problem, and insultingly implied I didn’t know how to start the car I had driven for a year!

    1. Hi Michael,
      Thank you for your post. We have spoken with our technical team and they have advised that the issues you are experiencing are not to do with the Hybrid recall software update. This is due to the recall relating to the high voltage hybrid battery not the 12 volt auxiliary battery. We would advise speaking with your dealer further and if you have any more questions please let us know. Many thanks.

      1. The garage have replaced the 12v battery as they said it failed their tests. We got the car back last night. This morning, it started fine but dab was silent. The tailgate was not locked. I stopped the car, locked it, unlocked it and started again, and dab was back.

        How do you explain those problems? Would ecu damage cause this?

        1. Hi Michael,
          Thank you for your reply. Unfortunately we cannot explain these issues without a visual inspection. However, we have spoken with our technical team and they have advised it can take a little time for the DAB to power up properly once a battery is replaced. They believe from what has been described that this is the case and the DAB should function from now on. Please let us know if you experience any issues with this further. Many thanks.

  31. My dealer WKB at Waterloville Hants. suggests an “optimiser trickle charger” to solve the problem of my Sept. 2011 Auris Hybrid starting problems, they advise my daily town driving is not enough to keep the battery charged and start the vehicle. I have been driving this car for 4 years and this problem has only just happened, they have tested the battery and say it is fine but needs charging, is a trickle charger the only answer??

    1. Hi Bob,
      Thank your or your post. We have checked this with our technical team for you. Without knowing the exact amount of use of the car we can advise that a trickle charger will always help keep the battery to the optimal level.

      If the vehicle is driven for only short periods of time, particularly at this time of year where the heater, lights etc are all used, then the battery can deplete more than it is charged. Therefore over a period of time engine starting could be difficult. It sounds like you have had your vehicle check by your dealer to make sure everything is working correctly with your battery, so we would therefore advise that if the vehicle is left for long periods of time without being used then a trickle charger may help in these circumstances.

      Hope this helps and if you have any other questions please let us know.

    1. Hi Cliff, the battery issue mentioned only applies to the latest generation Toyota Auris (including Hybrid) from December 2012 onwards. No other models were involved. Hope this helps.

  32. Is this software upgrade a permanent fix to this problem? I have ordered a used (albeit 2 month old) Auris HSD Excel Tourer and despite calm assurances by the dealership, I am tempted to cancel my order.

    Does this affect all Excels or a certain batch of them? WIll my vehicle be affected as its pretty new?

    I spoke to an owner of a hatchback Excel and said there’s no issues.

    1. Hello Abir
      Thanks for your post.
      Just to reassure you, this software upgrade does cure this problem. Not all vehicles will be affected with this issue but should a dealer check a car and confirm this is the case then it can be quickly resolved with this upgrade and will not recur.
      Hope this helps but do let us know if you have any other questions.

  33. I’m yet to have my car checked but getting it into my local garage is proving difficult. They seem to be over booked (I wonder why) and not overly helpful. Think I’ll try a different garage and see if they are more pleasant.

    If this is so much of a problem for all current Auris cars why isn’t there a recall to sort the problem out?

    1. Hi Robert

      Sorry to hear about this. Let us know who your local Toyota dealer is and we’ll see if we can help. Otherwise and if you’d like to speak to someone about your experience, our Customer Relations team is there to help. They can be contacted on either 0344 701 6202 or 01737 367600.

      Thanks for the post.

  34. I have an Auris Excel which exhibited this problem 8 weeks after I bought it in January 2013. As others have found, I was treated by the garage as a fool who was unable to shut his car down properly and Toyota customer help was no help at all.
    In the mean time I have managed by doing frequent unnecessary trips, but today I had to again crawl into the boot to charge the battery. Finding this page online I was a little surprised that I hadn’t already been contacted by the dealer(they were quick enough, and persistent a month ago when trying to sell me another model).
    Can you clarify whether the Toyota dealer will call me when ready to do a fix or do I have to chase them or inform them that a fix is available?

    1. Hi Alun,
      Thank you for taking the time to contact us, we’re sorry to hear this.
      We have investigated the cause of a 12 volt flat battery and there is a permanent solution to this issue.
      We recommend contacting your local Toyota dealer: the fix is a 10 minute software upgrade that will be able to rectify this for the future. If you’ve already spoken to them, we recommend contacting our customer relations team at head office, they can be reached via this link:

      It should just be a matter of booking you in for the software upgrade!

      Hope this helps!

  35. I have had my Auris Hybrid for about 18 months now and have been really pleased with it until last weekend when it would not start after being left for 2 days, although I had been on holiday earlier in the year for 2 weeks and not had a problem. I contacted the local dealership who I must say were not very helpful saying I must have left something on and would have to get a recovery company to get it to the garage. Green Flag came out and charged the battery and all was well until this weekend and the car was left for 1 day and again wouldn’t start. This time I can’t even open the doors and the manual keys is vey stiff and I am frightened this will break in the lock. My husband went to the local dealership Hill of Stortford and again they were very unhelpful so we are left with a car we cant access on our driveway with my sons car trapped behind it. At least I would have expected the Dealership to have advised me last week to bring the car in to check if it has the fault outlined on your website and not left it until the fault happened again. They were really not interested. Very disgruntled customer.

    1. Hi Lynn
      Thanks for your post.
      We are very sorry to hear about the problem you have experienced with your Auris.
      You are correct, your dealer does need to see and check your car because if this was the issue you experienced, then a 10 minute software upgrade will be able to rectify this for the future. If you do want to discuss this matter further with us then we do have a customer relations team based here and they can be reached via this link.
      Thank you again for your post and if you need any further help please let us know.

  36. I live in Israel and I have this problem. I bought my Auris Hybrid car 16 months ago!! I’m still waiting for my garage to call me to come in to fix it!!! Every time I turn off my car I was told to turn the hazard light on and then off. This does work but it was supposed to be a temporary fix. Why isn’t Toyota Israel fixing this problem???

    1. Hello Marsha
      Thanks for your post and sorry to read that you have experienced this problem with your Auris.
      We would recommend that you speak to Toyota Israel directly about this issue so they can advise what the current situation is regarding regarding the software upgrade. We do know that the fix will apply across Europe but we will not be aware of the timings involved for other countries. Here is a link for Toyota Israel if this helps.

  37. Could you please pass me the contact details of your customer relations team, car is booked in again for 11.00am on 7th, before 10am would be good.
    Many thanks

  38. Auris Excel flat battery still happening after going into the dealership for the “fix”.
    Wednesday 2nd July returned from the dealership with the “fix” installed and place. Put the battery on charge overnight and the following morning, total 15 hours. Car ok all day on 3rd but on 4th battery discharged – conclusion, the “fix” does not work.

    Come on Toyota get your act together, you are supposed to be a world class player but this is definitely minor league.

    1. Hi David
      Thanks for your post.
      Very concerning to read the detail as we know the software upgrade does address the issue with the hazard warning light switch. We would recommend that your dealer checks your car again in view of the circumstances. If you need any further help or advice or would like to talk to our customer relations team please let us know.

  39. Have booked my Auris Excel in for investigation into the battery going flat. The Stop – Start function kicked in while at a level crossing and car only just started as battery nearly flat. I am aware of the software issue but surely the S/S should not have kicked in. Is this yet another problem or all part of the same one?

    1. Hello David
      Thanks for your post.
      Sorry to hear that you have experienced this issue and good to learn that your car is going to the dealer for investigation. The stop start function does work automatically if you have this feature switched on.

      1. Thank you David but my main point was that the Stop – Start function operated when there was insufficient charge in the battery to properly restart the car. Previously the S/S has not stopped the engine when lights, air con etc have been used.

  40. Yes, the flat battery has just happened to me. Very frustrating!
    Why have the dealers not been contacting us to have the fix applied?
    I had even had my first annual service a couple of weeks ago when the re calibration could have been applied. My dealer has supposedly only just found out about the fix. I am suspicious that the dealers are just leaving it up to the customer to shout when the problem happens instead of being proactive with a recall.
    I am surprised as well that the AA are not up to speed with this and not just logging it as a faulty battery.

    1. Hi Vic
      Thanks for your post.
      We are sorry that you experienced this problem and we can assure you our network are aware of this issue and have the necessary software upgrade to prevent this from happening again. Thanks also for your comments regarding the AA, while they will just try and get the vehicle mobile we will pass on these details.

  41. My friends of UK,
    many thanks for this information, I need a little more help.

    Im trying to update my car, my local dealer in Spain say that there is no software update for any Auris 2013 version, but we all know that is not true.

    Could you please give me any clue (internal document ID, software version code) to try to, with all the information, talk again with my local dealer and update my car. Not everybody have the luck to live in UK where customer care is a must.

    Many thanks.

    1. Hello Eduardo
      Thanks for your post and hope all is well in sunny Spain.
      We know that the fix was developed to update all European cars. Have you spoken to the customer service team at Toyota Spain about this? They will be able to advise about how this is being communicated to their network as we are not sure about the timings across each European country.
      Please let us know how you get on but here is link for Toyota Spain if this helps.

      1. Hello my friends,

        I contact with Toyota Spain, a customer care assistant phone me to tell me that there is no update related to Auris cars in Spain. After asking them that why in UK blog talks about it, the answer was that “UK cars are different”.

        1. Hello Eduardo
          Thank you for your reply.
          The issue which affects the Auris with the battery going flat after the hazard warning switch has been touched does affect Auris models across Europe. To rectify this issue a software upgrade is available which takes about 10 minutes or so and prevents this problem from happening again. If you have experienced this problem we would recommend that you talk again to Toyota Spain about this.
          Hope this helps and let us know how you get on.

          1. Finally Toyota Spain will fix the Issue, the start to send postal mail to all Auris hybrid owners and to petrol and gas ones will apply the update when they make the regular manteinance.

  42. Mr Toyota,
    Can you please confirm if this issue just relates to the Hybrid version or all variants of the Auris?

    I ask, because I have the Excel (non hybrid, 2014) and have had a flat battery.

    Many thanks

  43. I am the owner of a Toyota Auris (2013 model) and have recently experienced the frustration of a flat battery. We paid £75 to have the vehicle towed to the local dealership in Wolverhampton where they duly recharged the battery. I was less than happy with this response and reluctantly brought the car home – although the fault has been rectified, in as far as the battery is now charged, the cause of the problem does not appear to have been addressed and I expect to be paying a repeat visit to the garage when the problem inevitably recurs.

    1. Hi Christine
      Thanks for your post.
      Sorry to read about the problem you have had with your Auris. If the cause of this is the issue mentioned on this post regarding the hazard warning light switch then your local dealer will be able to resolve this issue with a quick software download. It will prevent this from happening again. If you are concerned about this issue and would like to speak to our customer relations team then they can be contacted via the attached link if this helps.

  44. I took my Auris Hybrid Excel to my local Toyota dealer yesterday to have the update done. After connecting their equipment they informed me that I do not need the update. My car was purchased mid March so Toyota must have installed the new software on the production line. Toyota must have the vin number that they started installing the updates from, could they just publish this so that customers can check without booking their car into a Toyota dealer?

    1. Hi Gerry
      Thanks for your post.
      Vehicles that were held in stock were rectified from mid February however because we know this issue has caused concern among owners, some have requested their vehicle be checked as a precaution. The moment the computer is connected it will tell the dealer which software version is in the car and whether the later version is required. We notice you purchased yours mid March which is why the upgrade had already taken place. Our first priority was to introduce an effective repair and we will now work with the network to ensure that all cars receive this upgrade as soon as possible. We do take on board the point you make about being able to check this online as we do offer this function on our website if an owner is concerned regarding a recall.
      Thanks for your feedback.

  45. Toyota services, at my dealer, conntacted me for the updated software package to be installed. Lets hope it does the job. Thanks to Toyota Wolverhampton for keeping me updated whilst awaiting the new software.

  46. I bought my toyota auris excel in September 2013, since then I had to take the car to dealers few occassins to rectify the problems. First started with Ac was not working. Now remote key doesn’t work, I just called the AA BREAKDOWN , waiting for their arrival.
    I am very disappointed with this car purchase, spent Approx £23,000.00 just 9 months ago, already so many hiccups in new toyota auris hybrid. Not happy at all as I was meant to take my ill son to primary care centre for his unwell condi on.
    It’s just annoying situation.

    1. Hi Dambar
      Thanks for your post and we are sorry to read about your Auris hybrid and the problem you have experienced. We are confident that the dealer will be able to rectify this matter for you but if you do wish to contact us further we would recommend getting in touch with our customer relations team who can be reached via the attached link.


        1. today I received the update
          friendly and knowledgeable staff
          I am very happy

          shame there is not a blog so also in Italy

  47. good day
    when the update will come in Italy?
    I am a happy owner of a touring auris hsd and am very happy with this car, but I’m terrified to remain at large due 12v battery.

    good day

    1. Hi Mauro,
      Thank you for getting in touch.
      We’re delighted to hear you’re very happy with your Auris Touring Hybrid!
      Unfortunately we only have information on this for the UK market. If you’re concerned we would strongly recommend you contact either customer relations or your local dealership, as they’ll be able to explain the situation and the permanent fix to you.
      To find your local Toyota dealer please visit: or to speak with customer relations visit:
      We hope this helps.

    1. Hi Raf,
      Unfortunately it’s not as simple as looking at the year your car was registered – it actually depends on when your car came off the production line. This is why we’d recommend contacting your local Toyota dealer as they’ll be able check for you. To find your local Toyota dealer please vist:
      Many thanks

  48. My Auris also experienced the problem of the flat battery, I am pleased to say after having had the software updated there hasn’t been a problem. Thank you Toyota after my wife and I having purchased your cars over the last 35 years my faith has been restored

  49. My auris hybrid is due to go into the garage for sorting out the flat battery problem. They say I would still need to disconnect the battery when I go away for 2 weeks shortly. This is a problem for me as I am an elderly lady driver and know nothing about disconnecting batteries etc. I am disappointed as I thought that sorting out this problem would be a permanent fix and I need not worry about the battery going flat. If the problem is not a permanent fix then I will get rid of the car (only 7 months old) and buy another car where I will not have the worry of flat batteries after leaving the car undriven for a week or so. I used to leave my Subaru Forester for several weeks and it would start first time when I got home (and I did not have to disconnect the battery).

    1. Hi Susan,
      Thank you for taking the time to contact us.
      We appreciate your concerns – please be assured as the issue you’re about to have fixed has nothing to do with the advice you received to disconnect the battery when you’re away. There is a permanent fix for the 12V battery going flat, which your local
      Toyota dealer will organise and put right.

      As a precaution we do say that if you’re not using your vehicle for a substantial amount of time, the 12V battery could naturally discharge. However, your car should be absolutely fine if you leave it for two weeks. If you do want to put your mind at rest then there are ‘Battery Conditioners’ on the market that connect to the battery and plug in the mains, these keep batteries topped up and do no harm to the battery for long periods of time.
      Hope this helps!

  50. An update: Yesterday my local Toyota dealer in Aylesbury (who have always been exceptionally helpful) contacted me (thanks guys!) to inform me that they have the software update and me to call them and get booked in!

    So the update is obviously moving, if you’re desperate due to your car going flat, you might want to re-check with your local dealer…

    Kind regards,

  51. Hi All!
    I wrote a few lines to the Burnaston plant regarding the issue ( They forwarded my query to Toyota Europe Customer Service (
    The last step is an email (with all the history of my prevoius messages to the addresses mentioned before) received from Toyota Italia that states “Starting from February 2014 all the new manufactured vehicles have the dashboard software updated”.
    I think that this means that all the vehicles produced after February 2014 will not suffer this problem.
    Nothing was mentioned regarding the vehicles produced before.

    I’m not an Auris owner, just trying to find out (and share) more information for a near future car change.


  52. Je possédé une auris touring sport hybride confort depuis mi décembre 2013 . A ce jour 6 pannes de batteries. je viens seulement de prendre connaissance du pb de warning. Il aurait été bon que chaque possesseur est été avisé de cette anomalie qui j’espère serait traitée rapidement . Personnellement cela m’aurait éviter des aller retour à la concession 60 kms a chaque panne et un planning perturbé.

    1. Thank you for taking the time to contact us. We’re sorry to hear you’ve been experiencing problems with your Auris Hybrid Touring Sports. Toyota GB has published a Technical Service Bulletin to its dealer network advising them of a permanent solution to this issue. If you still have concerns regarding the 12 volt battery we recommend you get in touch with your nearest Toyota dealer for further assistance.
      Apologies for any inconvenience caused.

  53. This won’t put me off a Toyota though repairs today may get me another year out of the old heap which has a new battery.

    I am surrounded by happy Toyota owners all of whom are full of praise for the standard of the local dealer and its willingness to engage with Toyota GB when there are problems to sort a fix or even turn in a problem car with a deal good enough to keep the customer with the brand. Cars go wrong and increasing complexity means solutions can take a bit longer; it’s how the automaker handles them that matters. Toyota has a good reputation for this unlike several other brands, whose cars we now rarely see in my neighbourhood.

  54. I contacted Toyota Customer Service some time ago, for an update on the 12v battery problem as I am thinking about buying an Auris Hybrid. I was told to take my car (which I hadn’t yet bought) to my dealership to get the problem sorted. A stupid reply – so I’m not their biggest fan.

    However, I must say that some of the blogs on this subject are bordering on hysterical (in 2 senses of the word)

    Yes, there is a fault which should never have happened. All major manufacturers suffer this.
    When Toyota identified the problem, they announced their findings immediately – that’s the right thing to do isn’t it ?

    The problem then is, everyone wants their car fixed straightaway – and many (judging by the blogs) want their car to be priority.

    But the solution hasn’t been rolled out to dealers – so should Toyota have delayed the announcement until the dealers are set up to fix the problem.

    I’m afraid Toyota are in a no-win situation so I do think a little patience and understanding is called for.

    After all, there is an immediate “fix” – switch the hazards on/off before putting the car to bed. Not ideal by any means – but hardly difficult.

    Come on guys, as our American cousins say “cut them a bit of slack” and don’t stress yourselves.

  55. This is ironic. I have a similar, intermittent problem with a 15-year-old car and was considering buying a new hybrid Toyota as recommended by a consumer website for my low (3,000m p.a.) usage.

    And now I find out brand-new cars have the same problem.

    Great. Just great.

    1. Hi Fred,
      Thanks for your post.
      We are in the process of finalising a fix and communicating it across our Dealer network. Unfortunately, we are not in a position just yet, to direct owners to a Dealer to carry out this permanent fix. When the fix is ready, we will update this blog post with further details.
      We hope this does not put you off purchasing a new Toyota Hybrid.
      Please let us know if you have any further concerns.

  56. I don’t think the cause of the problem is the hazard warning light switch, on my Auris I have a Bury hands free unit fixed to the dashboard and this unit covers the hazard warning light switch although it doesn’t not touch the switch, so It is not possible for me to easily catch the switch. I fail to see how this can be the problem anyway, it is possible Toyota know the real reason but are not saying for some reason.
    I have been buying Toyota cars over the last thirty years and have never had a breakdown, or, a problem until now, Toyota what is going wrong? just a few days ago my Auris has had the software up-date so I shall have to see whether it has rectified the problem, reliability is paramount, but at the moment I am not sure as to whether I can rely on the vehicle, Toyota your continued reputation is at stake here in this highly competitive market.

  57. Hi tobi

    I called the number you gave, however they had never heard of you!!

    Anyway details below as requested

    Reg BV14 UKY has about 2000 miles, Lancaster Chelmsford, Auris Excel hatch hybrid, vin 075510

  58. Tobi

    I have not heard from any one in your Customer Relations team! can you chese them up please, time is running out!

    I am thinking of emailing Naoya Taniguchi may be he can help!

    1. Hi Ian,
      As per our previous message, in order for us to follow this up further we need to know who your local Dealer is.
      If you would prefer to let us know by telephone, Customer Relations can be contacted directly on: 01737 367600
      Hope this helps.

  59. I had the same problem but complained bitterly to Toyota customer services. They agreed to send an engineer from Toyota 2 days later. All that is involved is a flash to the ecu it took 10 minutes. It has been great since, problem solved.

    I called Toyota customer services for compensation I asked for a1st year service voucher which I received the next day, I think if I had pushed it a bit more I feel that I may have got 2nd or even 3rd
    year service.

    good luck


  60. I had to call out the AA on two occasions as a result of a flat battery, the AA has emailed all of their patrols about the problem, I contacted the main Toyota dealer who denied there was any problem, the whole situation is totally un-acceptable and will do nothing to Toyota’s reputation.

  61. Hi if that’s the case, why are some. Customers being given the updat now??? I can’t wait until the end of may when the update may are may not be rolled out! I am off on holiday to France for two weeks at the end of of may, and should this happen I will expect Toyota to reimburse me for all the cost of getting me back on the road/home!!!!! This has taken to long to get resulved get a grip “customes first” before profit or there won’t be any?? Please contact my local dealer and let them know I require the up date now


    1. Ian, for some reason Toyota don’t seem to be taking this problem very seriously or realise how frustrating this is for their customers. I first had a problem with my 12v battery back in early January. Even after I gave them information from this website Toyota Technical still denied to my dealership that there was a problem with the battery. This is despite Post #94 (page 4) dated 28th January containing an explanation of the problem given by Toyota UK itself.

      I was told in late January that the software update would be out in 3-4 weeks. It was only after I had a rant on this forum on 11th March and, more publicly, on their Facebook page on the same date that I got some action. Toyota made arrangements with my local dealership and my car was updated on 21st March and has had no problem since (apart from the annoying DAB radio one described elsewhere but I can live with that). When I had my update they said it would be out to everyone else in a few weeks.

      Perhaps you should go a bit more public? At the very least complain to ‘’ that you’re missing out.

      Otherwise, I love my Hybrid and had intended to buy another one when my current one is 3 years old (it’s 14months old now). I understand that there can be problems with cars at times but it is simply Toyota’s attitude that will stop me buying from them again. I suspect I will not be alone.

    2. Hi Ian,
      We understand the frustration caused and can only apologise. In regards to a fix, we are currently working on a case-by-case basis before the fix is ready to be rolled out across the country. Given your circumstances, we will see if there is anything we can do. Our Customer Relations team will do their best to coordinate this further. If you could please let us know who your local Dealer is, we can then follow this up.
      Many thanks

  62. Hi David

    Is the update now available for the issue with the 12 volt battery?



    1. Hi Ian,
      David is currently away from the office hence my reply on his behalf.
      At present we are still at the stage where the advice offered in our blog post is still relevant and the most up to date. In short, while we are able to advise customers how to prevent the situation occurring in the first place, we are not currently in a position to direct owners to a Toyota dealer to carry out a permanent fix.
      This of course, is not ideal nor is it the final word on the matter.
      Our technical team are working on a process and the supply of the required equipment and instructions so that our entire network of Toyota dealers across the UK can carry out the necessary work.
      The anticipated timing for this to be completed currently stands at late May, although this is unconfirmed.
      We appreciate this is not ideal but remain grateful for your patience and for taking the time to post.
      Kind regards

  63. Share with what you said, Andy.

    The issue is the need for ignition off and ignition on to restore the sound. Likely to be a software or hardware problem.

  64. Hi Andy (Andy Gell, message on April 3, 2014 at 14:37) and Tobi as well,

    Have you have your DAB cut-off problem solved? I bought an Arius Hybrid 10 days ago and the car has only 400 miles on its meter by now but mid drive DAB cut-off has occurred five times, exactly as you described – suddenly no sound and cannot be brought back without re-starting the engine, but can be switched to FM.

    Left the car to local Toyota dealer today to check over as suggested by Tobi’s reply, but they cannot find anything wrong and do not know what to do with it.

    Any further advice on this problem?


    1. Thanks for your post.
      After investigating this further, the issue you are describing appears to be caused by digital blackout spots. This is where the DAB radio will cut out as a result of the digital signal weakening or being lost. Unlike traditional AM/FM radios of which slowly lose signal (much like you may have experienced in a multi storey car park), DAB radios are more immediate and will simply cut out if the signal is not strong enough.
      The government are currently investing millions of pounds in order to boost DAB coverage across the country. Once this process has been completed, the issue you are describing should no longer occur. The connection will then remain strong enough and therefore the need for the system to reconnect after disconnecting will not be required.
      We understand you have done so already, although if you do believe digital coverage may not be the cause of your issue, we recommend visiting your Dealer again and requesting they contact the technical team at TGB.
      Hope this helps.

      1. Hi Tobi & Bin,

        Firstly, apologies for this being in the “wrong” forum of 12v batteries not the general Auris forum but as we are just replying to posts it seems correct to follow the thread.

        The problem I have (and possibly Bin too) is NOT one of signal/reception. I trained as an electrical/electronics engineer and I do understand the very basics of how digital services work, i.e. when there is not enough signal it will “cut out” rather than just getting “fuzzy” as traditional analogue transmissions do. Therefore I’ve already progressed past level 1 helpdesk of “is there a strong enough signal?”.

        This problem has nothing to do with such issues. I often experience cut outs due to signal in low areas or behind buildings or when just in a general low coverage area and the sound will cut out and return when it can assimilate enough data again, exactly as it should! I agree that is a government issue not Toyota’s!

        However, the problem I have is that, randomly the radio sound will cut out (I can’t tell you if it was after a session of low signal – I don’t look at the head unit whenever it cuts out) but never returns on any station or channel, and the not “returning” is the crux of this problem. The head unit actually “looks and feels” as if in the background it is working as it should (changing stations will show normal DAB procedure of short delay, then station information pops up etc.) and it won’t say “no signal” which I believe it might with no coverage (I’d have to check that fact though). It’s almost like a software codec within the DAB software gets corrupted and the head unit cannot recover from this without a full power off/on and so the DAB although working at one stage of circuitry is effectively “muted”. The power button on the head unit is not a full power down and more of a stand-by arrangement, so the only recovery is ignition off and ignition on and then sound is restored. If the issue was coverage the powering off of the ignition and back on would not fix the issue obviously as the signal still would not be there!!

        Unfortunately I’ve not had time to follow this up and when it goes in for it’s first service (3000 more miles) I will bring it up. Being a total cynic I can tell you now, the garage won’t find the fault as it’s random and we will end up going down a nag to “change the head unit” line… I will be very impressed otherwise!

        Kind regards,

      2. This happend to my Auris intermittently following a traffic broadcast. I took the car to the dealership and showed them the problem without switching the engine off. They have now fitted a new radio and all is well.
        Hope that helps

  65. Have just returned my Prius Plug In to Jemca (Reading) accompanied by the AA, (Toyota Assist), for the second time (353 miles on the clock) with a flat 12 volt battery. The first time they said they could not find anything wrong. This time problems with 12 volt “gel” batteries was mentioned. They are investigating. The battery has gone flat twice now after two days of not using or starting the car.
    Please advise. Thank you.

    1. Hi John,
      Firstly, we’re sorry to hear about the problems you’re having with your Prius Plug In and regret any inconvenience caused as a result. While we very much appreciate you getting in touch, we are reluctant to offer advice or any form of diagnosis without physically inspecting your car. As such we need to refer you to your Toyota dealer for further investigation. All authorised Toyota dealers have direct access to each and every department at Toyota Head offices, including our technical team who will be able to offer them any support as may be required.
      As an alternative, if you wish to contact someone directly to discuss your experience you may wish to get in touch with our Customer Relations team either by calling 01737 367600 or by email via the following contact link:
      Thanks again for getting in touch.

    1. Hi Mike,
      Sorry to hear you are having some battery problems. We must confirm however, the 12v battery related issue we are in the process of rectifying with the Auris, would not be the same issue you may have experienced with the Prius. Of course, it’s not easy to diagnose anything specific without inspecting your car so we would direct you to a Toyota Dealer in the first instance should you require assistance. Your nearest Dealer can be found by clicking here:
      Hope this helps.

  66. I see Derek Gee was given a voucher for a service as compensation for this problem.

    I had the software update done a few weeks ago in advance of the general release. Someone from Toyota made a special trip to the local dealership to do it, possibly because I’d complained here (see below) and on the Toyota UK Facebook page, but I rather thought I might also be the guinea pig to test it out in the ‘real’ world. I’ve had no problems since the update.

    I endured this problem for more than 2 months, had 2 Toyota Assist callouts, 3 trips to the dealership and the loss of my car for 7 working days in the workshop. Do Toyota think that any of the rest of us who have been affected by this flat battery problem might be compensated in a similar way? If not, why not?


    Tom King

    1. Hi Tom,
      Thanks for your post.
      We’re glad to hear that the fix has helped resolve your issue and are sorry that you remain unhappy.
      May we suggest contacting Customer Relations who will be able to assist you further, they can be contacted through this link:
      Hope this helps.

  67. Further to Derek Gee’s comments on 10th April 2014 , I have a 5 month old Toyota Auris Hybrid which has broken down twice (fully discharged battery) recently within a 4 day period.
    After calling out the AA (Toyota Assist) the battery power was restored and the AA mechanic referred me to the main Toyota dealer in Leeds, informing me that Toyota had a software update which was designed to resolve the ECU problem.

    When I got the vehicle to the dealer they confirmed the fault , but were adamant that there was no available software to resolve the problem and advised me to turn the hazard warning lights on & off each time I left the vehicle.

    I took a copy of this blog to the dealer but basically they rubbished the comments and showed me the official bulletin from Toyota with the temporary solution (as above).

    It was then that I refused to budge & insisted that they rang Toyota Technical.

    Lo & behold they returned – rather red faced – to admit that Toyota have in fact got a Software kit to flash the update, but apparently there is only one kit available in the country and I am now waiting for it to arrive at my dealer.

    Clearly Toyota are not being entirely honest about this problem – even to the extent that the main dealers are unaware that there is a solution available.

    It is disgraceful that that Toyota are marketing & selling a car worth more than £20k with an existing technical design fault.

    1. Hi John,
      Thanks for posting. Firstly, we’re sorry to hear about the problems you’ve experienced and for any inconvenience that may have been caused as a result.
      While we appreciate you may feel let down, we have at no stage tried to mislead anyone. Problems can, and do happen but don’t always reveal themselves prior to production and sale. Often it takes time for issues to manifest and reveal themselves. It’s then up to us to do all we can to provide solutions in line with our commitment to customers under the 5 year warranty. However, as you rightly point out, in this instance our Dealers have had neither the equipment or the technical guidance in order to carry out the remedial procedure themselves. We are now looking to address this as a priority. As we understand it, the work required for your car is due to be carried out today; we’re confident this will provide a lasting solution.
      Once again, apologies for any inconvenience caused but appreciate you taking the time to get in touch.

  68. Toyota are committed to sending the software to all dealerships by the end of the month (April) to flash the ecu with new software to stop the battery going flat.

    I have my auris hybrid estate booked in to have it done next week!

    So hopefully no more flat battery’s !!!!

    1. Will the Toyota dealers contact all the Auris owners to update the software as a matter of course, or will it be offered only to owners who have had problems?

      1. Hi Gerry,
        At this stage we are yet to roll out the final solution. Our priority will be to fix customer vehicles that are experiencing the issue. As soon as we have further information we will update this blog post.
        Hope this helps.

  69. My 426 mile old Auris Excel (none hybrid) also had a half flat battery after being parked in my garage for 3.5 days.

    When you pressed the stop/start button all the display started to flash with clicking noises.

    Checked the battery which was down to 8 volts so I hooked up a charger I have and called my dealer.

    After a 15min charge it had enough energy to crank the engine and started.

    My dealer could find no fault and thought the most likely cause was me leaving something switched on. Car was locked and lights set to auto.

    Plus if I had left something on, I would have just charged it up and got on with my life 🙂

    I was told, if it happens again I should just call the AA and get them to do a report.

    Not really the answer I wanted after spending so much on a car…

    Browsing about, I found this, but the Toyota Owners Club forum say a dealer Toyota blog says the issue only relates to the ZWE186 Auris Hybrid model.

    Can you confirm this, or as stated in this blog that it applies to all versions?

  70. I get the impression that Toyota are not treating this flat flat battery on the Auris seriously enough! My auris hybrid estate exell has key less entry which is an expensive cay and to be locked out of the car on the 3rd day from new! Had to call AA as key only opens the drivers door only,

    I was not told about this fault by the dealers as if I had I would not have bought it. I have noticed that from the answers from Toyota differ which is obvious to me that nobody can give a definitive time scale on this! The work around is turning hazards on/off. This not good enough, when I bought this car I expected every thing to work!

    Come on Toyota this is completely unacceptable and should be compensated adequately!

  71. Hi Tobi

    Yes the dealer has sorted out the radio, but i have not had any feed back, on the issue of converting the headlights to drive on the left?


      1. Hi Tobi

        One commend I’d like to make about the DAB radio in my Hybrid Hatchback which is brilliant when it works:

        Sometimes mid-drive DAB will completely cut out with no sound, forcing me over to FM again if I wish to continue listening to the radio. When it this state the DAB seems to “function” in that it will change channels and scans for stations and waits for a few seconds when selecting a station before putting information on screen, all normal DAB behaviour but no sound at all.

        When it does this the only way I can get DAB back audible again is by turning car off and on. Turning the head unit off and on does nothing. Changing to a different source, eg FM has no effect whatsoever. Making a call and disconnecting does nothing.

        Is this a known fault? it happens about every week or so.. I can live with it but it’s irritating having to effectively fully power down the car to get it back working again. Anyone else with similar issue?

        Kind regards,

  72. Hi David

    Thank for your help.

    I am off to France on holiday next week, but i can seem to find how to convert the headlights to drive on the left?

    Also do you know how i turn off the reversing camera beep! As i cant hear the parking sensors?


    1. Hi Ian

      Personally no idea about headlights, I don’t think it’s any more sophisticated than stickers! However as they are so bad and set so low from factory you will probably find they won’t dazzle anyone anyway!!

      Regarding reversing beep, Toyota dealership can plug this in and quickly turn it off so you only get one singular beep when selecting reverse as I had the same issue.. It’s impossible to tell what’s beeping, one tone for front range one tone for rear and another for reversing alarm all going at the same time!! Having a tight drive this was the first thing I did and it’s wonderful having it turned off. In my opinion it should be disabled as default with a screen setting to turn it on if you’d like. PS Make sure they do it FOC as you’ve just bought a new car with them, the did for me.

      Kind regards,

  73. I forgot to say that battery charger and wires are completely concealed after battery charger install.
    No drilling, cutting ect , just place covers as usual.


  74. HI,
    I have a new auris sport hybrid estate, It would be a great if the auris was fitted with a amp gauge,
    this way we would know what state the battery is in so we could charge the battery and alleviate
    calling the AA who came and got the car to charge the battery its self.

    the car was only 3 days old when this hapend., I took out the key from the fob and opened the drivers
    door, no other door including the tailgate which prevented access to the battery.

    So rather than worrying about the battery going flat again, I took out the first shelf in the boot. connecting my battery
    charger to the battery after removal of battery cover, put the battery cover back, connect the charger
    to ext lead and it showed tree quarter charge, so left it trickle charging overnight.
    disconnected charger from extension lead, replaced the shelf leaving the the charger still connected to the battery, so next time I just lift shelf and plug into lead. I am going to leave this as permanent fix.

    I paid a lot of money for my car and 3 days later I’m locked out, I didn’t expect this, Toyota have spotted this a long time ago, going from a normal gear shift with clutch is a big jump and toyota
    should understand this and at least fit an amp meter, access to the tailgate, perhaps a bigger battery!

    The hazard waring on/off seems to work o.k. but I hope the permanent fix is done soon.

    All the best Derek

    1. Hi Derek,
      Thanks for your post.
      We are sorry to learn you experienced this issue and we appreciate your feedback. We can assure you we are working on a permanent fix and will have more news very soon. Keep an eye on our blog for the latest developments.

  75. Hello
    I have just taken delivery (2 days ago) of an Auris Hybrid. Is it safe to assume that the battery problem has been fixed now or should I switch the hazard lights on and off as advised?
    The dealer didn’t mention the problem and I only discovered this forum by chance.

    1. Hi Nick
      Thanks for your post. Good to hear about the delivery of your Auris Hybrid.
      At this stage we are just waiting for confirmation about whether a production change has taken place and we will be updating the post once we receive this. Glad that you have seen this post and we would recommend that you follow these instructions as a precaution for the time being.
      Let us know if you have any other questions.

  76. Hi David

    I have taken delivery of my new Auris hybrid today, reading below, I can work out if the 12v flat battery issued has been resolved? And if it has how, do I know if my car has had the software update?

  77. I am having the same problem! Hybrid exell sports estate, my battery went dead after 3 days from new!

    Took it to local Toyota dealer and was advised that I should turn hazards on/off and that a solution is being made.

    The thing he told was to make sure that both fobs should be placed some where out of reach of car, I live in a large house but could not find anywhere in my house that was out of range of the car!

    Any ideas on this situation please


    1. Hello Derek
      Thanks for your post.
      So long as you follow the instruction in this post to make sure you have not inadvertantly pressed the hazard warning switch then this will prevent this issue causing the flat battery. With regard to the keys, so long as the fobs are more than 2 metres away from the car then you will be fine. We will have a solution to this issue very soon.
      Hope this helps.

  78. Hi David! First of all Thank You for answering all the questions you receive in this blog. I’m writing from Italy. Also Toyota Italia customer service confirmed me by phone that the “hazard” problem exist and gives me the same directions about how to prevent it. I’m interested to buy in the not too distant future an Auris wagon 1.6 petrol (not an hybrid model) BUT, as all the others Toyota Owners and Customers, I would like to have the car delivered to me with this issue fixed.
    Are there any expectations about when it will happen (eg. one month, one year)? Auris Touring Sport is still manufactured in the United Kingdom?
    Cheers to All,

    1. Hello Riccardo
      Thank you for your post and kind comments from sunny Italy.
      This will happen fairly soon and we will be posting again as soon as we can confirm a timeframe for this. Sorry that we cannot confirm just yet but please do keep an eye on our Blog for the latest news. Auris Touring Sports are still built in the UK.
      Hope this helps but let us know if you have any other questions.

  79. Hi David, Thank you for your response. Please can you confirm ‘Ready’ mode will be with the gearbox selected in Park, with indicator light on. Obviously I don’t wont the to move!

    1. Hi Andrew
      You are correct. In ready mode but with the car in Park.
      Hope this helps but let us know if you have any other questions.

  80. Hi, If I wish to use one of the 12v aux sockets in the car. Should the car be in the ‘ready’ state or in ‘power on’ ie one press of the power switch with foot off brake pedal? Please explain in which modes will the 12V aux socket be powered without affecting the 12 V battery? thanks

    1. Hi Andrew
      Thanks for your post.
      The answer to your question is “ready”. We recommend this because, when in this mode the vehicle will use the engine which can then recharge both batteries as necessary. If only using in “power on” (ACC mode) there is a risk that you may drain the battery. The sockets will work in ACC mode but they will not work when the ignition is off so that anything connected does not drain the battery.
      Hope this helps.

  81. I am having frequent battery problems with my Auris, purchased April 2012. I know your post describes only cars from Dec 2012, but is it possible that this is occurring in the earlier model too? My car is back at the dealership for the second time, and as yet they are unable to find the problem. They have had my car for three days now, and likely to keep it for longer, unless they find the source of the error. I can live without it for a bit longer but this shouldn’t happen to a car of only two years old. The service from the garage has been great so far, but given all of this information I have found, I am surprised no one mentioned this as a possible cause.

  82. Purchased a Toyota Auris Excel 1.4 D, on 31st Jan, experienced a flat battery on Monday 10th March, on returning to the car after a week away. Called the AA out to the airport, the battery was charged up allowing us to drive home. We were not very pleased. Informed Toyota delership in Wolverhampton from where the car was purchased, and took the car there the next day. The sevice manager took the car into the workshop where the systems wre checked, on return after an hour the manager explained all systems were ok, but then explained the probable cause of the flat batery was the hazard warning switch, He then went though the process to prevent this happening. He then advised he was awaiting a permanent solution from Toyota. Full marks to the sevice manager. But sales staff should have advised us of a potential problem. Toyota have a big PR exercise to win back confidence in their products. Having two sons who have just bought new Hyundi i-30’s they keep reminding me that they dont have flat batteries.

    1. Hello Keith
      Thanks you for your post and we do apologise for the inconvenience you were caused.
      We understand your comments and are sorry that you were not advised. We are in the process of arranging rectification of this issue with our dealer network and will post an update on our Blog soon.

  83. I contacted Toyota Customer Services as I’d read the fault had been identified and new production is now OK. I wanted to check before buying Auris Excel Hybrid.
    Reply – what battery problem ?
    When I gave fuller information I was advised to take my car (not yet purchased) to my local dealer
    and it would be fixed under warranty.
    Pathetic. There is no recall in place for “older” cars, so one can only assume, nothing is resolved.
    A lost sale.

    1. Hi Bill
      Thank you for your post.
      We now have now resolved this problem (via a software update) and we are currently working with our network to fix outstanding vehicles.

  84. I first had this problem with my 2013 Auris Excel hybrid on 15th January therefore I’ve been sitting with a faulty car for 9 weeks now. The car was taken to the dealership who kept it for 2 days and then denied there was anything wrong with it.

    After a second failure a week later the car was with the dealership for a week. They were testing it on advice from the Toyota UK technical bods. In the meantime I found the info re the hazards via the internet as it had been occurring in Italy and Germany plus a few cases in the UK. Having supplied the info and internet links to the dealership Toyota UK still denied that this was a problem. When they later admitted what the problem is you can imagine my anger as the problem has been known about since at least January.

    My local dealership have been very helpful throughout and are suitably embarrassed by the situation however I feel let down by Toyota UK over this. I was told a software rewrite would be available in 3-4 weeks but we’re long past that now. Meanwhile I have had a faulty car for two months.

    I was initially advised to drive the car for 20 mins every day to keep the battery topped up (inconvenient) and then advised of the workaround on 13th February so have been using it since then (for almost a month) but have a constant worry that I’ll forget to do the workaround and have a flat battery at a time when I really need the car. In short, I don’t have the fully functional car I paid for and am fed up with the aggravation of it. I get the distinct impression that this is not a priority for Toyota. The sooner Toyota get their collective fingers out the better.

    To add insult to injury I’ve received a marketing email today with the subject line – ‘How healthy is your Toyota Hybrid?’ Oh how I laughed.

    1. Hi Tom
      Thank you for your post.
      We have seen your email through to our customer relations team who will be in further touch with you. We should mention that a resolution is now available for this issue and your local dealer will be able to rectify this for you.
      Hope this helps.

      1. Hi David,

        Just read my inbox thread update to find:-

        “We should mention that a resolution is now available for this issue and your local dealer will be able to rectify this for you”

        When was this and exactly as I had previously asked, why wasn’t this communicated to all of us with a problem? I had hoped for a bit of a “release statement” on it at least rather than yet another disgruntled owner having a winge to be the way we find out that the fix is now here!!

        What is the fix exactly?

        Kind regards,

        1. Hi Andy
          Thanks for your post.
          We have established a resolution to this issue (which involves updating the software) and we are now in the process of obtaining the necessary equipment to distribute to our UK network. Once this is completed we will update this post so that owners will be able to book in their car for this to be undertaken. We will certainly keep you posted on this.
          Let us know if you have any other questions.

  85. I have a 2013 Toyota Auris Excel 1.6 Petrol (Non-hybrid). I like most things about the care BUT within a week of purchase from new, the car failed to start due to a flat battery. The battery was tested first by the A.A. then by Toyota engineers, with no problem discovered. I had the same experience a few months later, the battery was re-tested … again nothing found. Today the same thing happened for the third time. My local (helpful & supportive) Toyota dealer seems as mystified as I am, but has fitted a new battery. I have read the theory relating to the hazard warning switch, but am a bit dubious about this as an explanation in my case. I wonder if other Auris (non-hybrid) owners have experienced something similar.

    1. Hi Phil
      Thanks for your post.
      In view of your comments we would recommend that you try this, particularly if the car is going to be left for several days. Otherwise your local Toyota dealer will be able to help you.

  86. Thank you for this helpful and informative post, which I only found by searching online after having to call out the breakdown service yesterday to a flat battery on my May 2013 Auris 1.6 petrol. When I spoke to my Toyota dealer today they seemed non-committal until I read this post to them. I was left with the clear impression that they knew about the problem, but weren’t saying anything until they’d heard something definite from Toyota.

    What is the likely time-scale for the permanent solution please? I can appreciate that it may take a little time to come up with a permanent solution (which must surely involve a recall), but in the meantime wouldn’t it be wise to notify owners of subject vehicles of the situation and the checks which can prevent an unexpected flat battery? If I had known about this last Friday, it could have avoided a breakdown on Sunday! It wasn’t a crisis – but it easily could have been.

    1. Hello Angus
      Thank you for your post and we are very sorry to read of your experience.
      As the post confirms, we are aware of the problem and working very hard to rectify this. We are waiting for more details regarding the time scale involved but do not anticipate this taking too long from now. Just to clarify one point though, it will not be a recall as these are only associated with issues relating to safety, but it will involve us (via out network) notifying Auris owners to return to their local dealer at their convenience for the rectification to take place. We will be posting further news on our site as soon as we are aware of this.
      Hope this helps for now but do let us know if you have any other questions.

      1. Hello David,

        Thank you for this clarification. I think it would be helpful if your dealer network notified relevant owners of the contents of your original post without delay, rather than awaiting the final solution.

      2. Hello David,

        I have just been on the phone to my Toyota dealer to book my car in for its first annual service in May. I mention the flat battery problem in the hope that the promised solution would be in place by then so I could kill two birds with one stone and avoid a second visit to the dealer. My dealer claimed to have no knowledge of this problem whatsoever. This is a ridiculous state of affairs and I felt as if I was being treated as an idiot from another planet.

        Questions, please:

        1. Have your dealers been alerted to the flat battery problem. If so, when and how. If not, why not?

        2. When will the promised solution be in place? I believe ‘late March’ was mentioned at one time.


        1. Hi Angus,
          Sorry to hear of your experience.
          We are in regular communication with our Dealer network and this issue was communicated on 12th February, apologies for any confusion caused.
          We can confirm the solution has been reached and the resolution will include a software upgrade. We are currently in the process of distributing the software to our UK Dealer network.
          In terms of time frame, this should be within three weeks, although we will add a further blog post as soon as we can confirm this schedule.
          Hope this helps.

  87. Hello,
    I would like to know the difference between 2013 and 2014
    is there the smae problem in battery
    Am from Egypt by the way


  88. With all the extra ancillary kit on the EXCEL HSD it needs a higher capacity LV battery. I was told it was only a problem with EXCEL spec HSD cars and I have been monitoring mine via the service screen. Even when it is used every day the service screen shows 11.9v after a couple of days. It may be a deep cycle specialist battery but 35aH is still very small for the start up load . I have had no problems yet (5 months) but a flat battery in my garage with the rear door locked would be a real challenge.

    1. Thanks for your post Ian.
      Hope these details have helped clarify the issue. Just to mention one point though, the 12v battery fitted in a Toyota hybrid does not need the start up load of a conventionally powered car. This is because it does not need the energy required to turn a starter motor, instead it is just opening up a series of relays as the larger hybrid battery will be starting the engine.
      Hope this helps.

      1. Hi David,

        Thank you for the update, very interesting! Such issues can arise with brand new models which shows although some testing happens before released, not every possibility can be so it relies on a large user base (us!) to find such problems. What pleases me is a manufacturer who will put hands up, admit an issue and fix it! So personally for this particular issue I’m happy if it’s quickly fixed. Let’s hope a software update is soon forthcoming so the ECU isn’t left fully alive waiting for a second signal from the switch that never arrives with it! From a distance this seems like a “timeout” implementation issue which should be do-able! How will this be communicated to all HSD owners?

        One thing I’d like to ask about aux. battery rating: When I was in local Toyota dealership the other day trying to get my spare wheel sorted (the doc. sheet Toyota dealerships have for this is wrong as the parts don’t fit properly – I need to speak to someone about this) they volunteered exactly the same info on this 12v issue as you stated and the temporary button press “fix”. Their own sales person’s cars are going flat (embarrassing) and they (Toyota!) wonder why the decision was made to put a smaller Auxiliary battery in the new Auris than the Prius. Apparently the Prius aux battery is a larger capacity. Is this true? If so why would a vehicle with the same HSD drivetrain as the Prius get a smaller Auxiliary battery as surely the differences in electrical systems are negligible?


        1. Hi Andy
          Thanks for your reply and glad this post has been useful for you. We will be updating this as soon as we have a resolution and we appreciate your comments about this. Turning to your question regarding battery output between Prius and Auris hybrid, the battery rating in the Auris is smaller than that of Prius. This is because the electrical systems are very different, the logic in the body ECU is such that the battery is designed around the ECU functionality so it did not require the same output.
          Hope this helps but let me know if you have any other questions.

          1. Clearly from what Andy said, the Auris battery was badly designed around the ECU. Forecourt car batteries going flat is hardly something you want.
