    Snowed the past few days, Was leaving our gravel road as snow was beginning to clear out, our 2017 prius with 158k miles randomly popped up pre collision system warning, check engine, and a few other lights, and ac and heater dash fully went out as well as our ability to roll down any windows, all doors lock and unlock still with zero issue via control, and the door button, just not able to roll windows down. It all came at once, wondering if anyone has dealt with this before or could give us any pointers as it sounds like an electrical issue or something disconnected. Thanks

    Most likely, the hybrid system failed (Inverter, high-voltage battery, etc.)

    To accurately find the cause of the failure, it is necessary to diagnose the car.

    See the topic on how to do this conveniently.
