I am not sure if anyone knows about this or can help me figure out what is going on, but basically, twice now I have sat in my car with the windows rolled down (at a beach parking lot during COVID, I was trying to avoid the risk of getting the virus) and the battery dies. I was sitting there for maybe an hour and a half to an hour. I took it to Toyota and they didn't find anything. I had the battery replaced in march so I don't think that is the problem. I have tried to do some research and have had no luck.
No info. Which battery is dying the 12 or the hybrid? In what mode is the car in when your sitting in it at the beach acc or the car is running and ac is on? How many miles on the car?
Most owners don't understand "modes". To put it another way.......IF anything in the vehicle was ON at the time.....radio, dome lights, etc. then the power drain killed the battery. Having the windows down really had nothing to do with it.
