Picked up Model 3 yesterday. This morning the car says that the rear drive unit failed. “Exiting and reentering the vehicle may restore function”. Well that didn’t work and the wierd thing is that I can not power down the vehicle completely from the touchscreen, it immediately turns back on. I’ve tried the scroll wheel reset while holding the break. That does a quick reboot but does not power down completely. Any ideas? Tow truck is on the way! And I’m 200 miles from home!
