I have a 2008 Prius with 55k miles. Recently (within past month) had 50k check at Toyota Service station.
Here is the scenario…
I drive to work just fine. When need to run an errand 2 hours later, the car will not start. I put key in an press power button (with brake depressed, all the normal lights on the dash light up, but engine doesn’t turn on. There are some funny things like gas light on, but full tank. I press the power button again, and the car beeps continuously (beep, beep, beep as opposed to beeee…eeeeeep) until I remove the key. I tried turning it on multiple times, with similar results. Fast forward 6 hours, I go to try it again and it turns on like nothing had happened previously.
I called Toyota, and they said the auxiliary 12V battery was likely dead (despite having just driven to work), and it recharged itself after sitting for a while. They said that it should be replaced… I am suspicious that it might be an electronic issue or something else - does anyone have any ideas?
