I've bought a Toyota Auris Hybrid 2011 in June last year. I've got no issues until November, when for the first time it didn't want to start. For next few weeks the issue didn't come up, so I thought I've accidentally activated steering wheel block or something similar. However, it appeared a month after, and yesterday.

I've identified the problem a bit more. It had happened until now only after a few days the car was idle. Normally the READY lamp goes on a few seconds after pressing start, but when the issue happens, it doesn't go on even after 10 seconds. However, I've also found a solution. Turn car off, open and close doors and try again. After a few times it will start, and drive without any problem.

What can cause such strange behavior?

  • any warning lights? security? key fob missing?

  • @Ben nothing extraordinary, after starting the car with non-ready mode I have a standard set of all warning lights, but it's the same when I consiously start that mode... Once it goes ready, there are no warnings...

  • How many miles (or KM) are on the car? While seven years old isn't ancient for a hybrid battery, it's not unheard of for a cell to start going bad. Also, have you cleaned out the battery fan ventilation system since you bought it? Dec 20, 2017 at 12:45
  • @Pᴀᴜʟsᴛᴇʀ2 the engine is started after the hybrid system has been on for bit less than 10 seconds. Before that, the computers boot up using the 12V battery, not using the hybrid battery. Also, the hybrid battery will probably last for 20 years, whereas the lead-acid 12V battery will need to be replaced after about 5-10 years. So, I think the answerer here has a point.

  • @juhist - Eh, don't count on a hybrid battery lasting for 20 years. They offer replacements for Toyota's with less than 10 year on them ... should tell you something. Dec 20, 2017 at 15:43

you can check on this link, similar issue and it is due to bad 12V battery https://www.youtube.com/watch?v=qvTWSDuUPUs

  • I have faced same issue. after replace the start battery it is fixed Jan 16, 2018 at 10:17
  • Confirmed, I haven't got the hybrids need the 12V battery in the same way the old-timers do. The service asserted me the battery is OK, and once it died completely I've finally learned the hard way that your answer is perfectly correct.
