I was driving along coming up to a red light. Regenerative braking was doing its thing. Then all of a sudden, the car started to shudder to a stop. It was like the pulsation of anti-lock brakes. It was a bright sunny day with dry roads and 88 degrees. The car showed P like it was in park, and a bunch of error messages started cycling on the screen. Car needs service, power reduced, charging not possible, automatic emergency braking disabled, etc. There may have been more. I don't remember. My dad was with me. He was able to roll down his window and open his door. I could not. The air conditioning had shut off. Yes, I was able to use the manual override to open the door because it was getting hot very quickly in the car. I called Tesla Roadside Assistance. They had me try to reboot the MCU. That did not work. In the meantime, my dad was able to push the car with great effort to get us out of traffic. Apparently the car wasn't really in park. I was able to steer the car.
I got the text from Tesla that the tow truck would arrive in 90 minutes. While I was waiting, the car slowly started to come back. The seat and steering wheel would start moving like going between Easy Entry and my driver profile. I was able to roll down my window. Next I tried to reboot the MCU. It worked that time. I was able to turn on my 4-way hazards. The error messages were still coming up, although different ones. Parking brake not set; Car could roll. The traction control icon was also on for a while. I still could not get into Drive. After two more times of the car changing driver profiles on me, the car came up like normal with no more error messages. I was able to put the car into Drive and move it a few feet to get to a more optimal safe position away from traffic. I called Roadside Assistance again in case they had done something remotely to reset the car. They said they did not (and could not). They recommended that I still wait for the tow truck.
When the tow truck came, he was able to drive the car onto the flat bed and (I assume) get the car into park like normal and have the parking brake set. The flat bed was still in a ramp position when he got out of the car and the car did not roll back.
And now my car is parked at the service center.
