    Our Prius had been sitting all week because it was out of inspection. No problems like what I'm about to describe. We went to take it to get it inspected this morning and it wouldn't turn on. After monkeying around a little it kicked on and off we went. On our way home we stopped at a store and had no problems. We checked the energy display and the battery symbol was fine. We got home, shut the car off, went to lock the doors and nothing would happen. We attempted to start it again and it was completely dead. No error messages, no beeping, no nothing. I read that it could be the battery, but everything had been fine until we shut it off. Does anyone have any suggestions?

    Check 12V battery. The only way to be certain it is good is to pull it and take it to an auto parts store for a load test. Intermittent operation can be a sign of a failing cell in the 12V.

    Replace the 12V battery if it is more than 4 years old. If newer, first try charging the battery overnight. Use a battery charger intended for AGM batteries, 4A current setting.

    welcome! nothing to add. keep in mind the battery icon is for the hybrid battery, but you need the 12v to boot up the computers and make the high voltage relay. all the best.(y)
