Recently Ive been having issues with my prius 2008 , it all started when I was driving back home and 3 lights came up randomly. They were the VSC, (!), ! With triangle. I parked the car and turned it off and turned it back on the engine would not start and the 3 lights from before came up in addition to the check engine light, the abs, the emergancy brake and anti skid, and then the red car with ! Came up on the navigation screen. I had to unplug the startup battery and pluged it back in. it started and was fine for about a day. Cant run any tests until it happens again. We had the 12V battery checked and it is just fine. Any ideas?
