Toyota Yaris Mk4 buying used: How I would reduce risk of 12V battery problems 

The video about Toyota Poland is also one of my videos. This is the link to the video for anybody reading this comment ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EHtg81kM-FU.html I made this video about buying a used Yaris Mark 4 before I found out about Toyota Poland. I still think the key message from this video is correct ... if buying a used Yaris Mark 4 of any mileage then you should get the dealer to replace the 12V battery BEFORE you purchase the car. I am still trying to find out if Toyota GB dealers have the new test equipment that Polish dealers have got ... and if Toyota GB will replace failed 12V batteries under warranty. If anybody knows please post a comment....

When my car failed to start and I was at the dealer collecting my car after the battery had been charged overnight ... one of the many questions I asked was - is the problem fixed in the new 130bhp 2024 Yaris. Unfortunately, this happened a few months ago (Oct-23) and the dealer did not know because they had not even seen the new car. I am in email discussion with Toyota Customer Services about my car and this is one of the many questions that I asked in my last email ... I suspect they will not answer the question but if I get an answer I will put this and any other useful information into a video. (I am not sure whether the 2024 Yaris is called the Mark 5 or just an update to the Mark 4???)

@@Helpful-Stuff btw, is this flat battery issue impacted hybrids only or the regular one too?

The flat battery issue only affects hybrids. - The hybrid 12V battery charges from the high voltage traction battery via a DC-DC converter. It can be a small battery because the only thing it needs to do is turn the computers on. - The petrol engine's 12V battery charges via an alternator. The battery needs to be big because it needs to turn a starter motor that starts the petrol engine and on a cold winter morning that may require quite a bit of current. Incidentally I am not sure where you live but in the UK Toyota GB only sell Yaris Hybrids. No petrol Yaris are available in the UK.
