You must be tired of people complaining about low mileage hybrid cars failing to start due to a flat battery, but a recent furthur problem produced some surprising information. When my year old Toyota Yaris Cross wouldn't start it flagged up a technical malfunction requiring dealer attention, so I called out the AA who came very promptly. Even without looking at the car the AA technician said it would be a flat battery, which it was, and this surprised me because, although I don't do a big mileage, I do use the car regularly being aware of the problem. However, what surprised me was that he said this was not a unique problem to Toyota (who have downsized the 12v battery) but applies to all makers of hybrid cars. In this case I think it makes them all unfit for purpose. I have previously has two two Toyota Prius which never gave this problem and the AA man said that still seems to be the case. Something seems very wrong somewhere.
