2007 Toyota Prius. Twice this week car failed to start; battery ok ~90% charge. Had to be jumped to start. Toyota mechanic finds nothing.
2007 Prius. Twice in the last week, it has failed to start. Each time, I had it jump-started, and went to the Toyota dealer. Both times, a mechanic checked it thoroughly, and found nothing wrong. The battery is holding a 90% charge.
When starting the car, I do nothing except what I've always done: step on the brake pedal and press the power button. Instead of starting normally, all the dashboard gauges and warning lights light up and remain lit, but nothing else happens. The gas gauge reports incorrect information about fuel (e.g., showing empty when the tank is half-full).
I turn the car off by pressing the power button, and it eventually goes off. In this situation, it takes several presses of the button for the car to turn off.
This morning when the problem showed up again, I tried to start it (this, after having already driven the car for ~25 minutes, and then turned it off for ~15), and the same behaviors described above occurred. This time, the ventilation fan started to run, but nothing else. No engine.
