NHTSA Complaint #11540029 — 2021 TESLA MODEL Y

I was accelerating out of a parking lot and was up to 30 MPH when the vehicle suddenly shut down and the rear end began shaking. The control screen went completely black/off. I could not accelerate at all. A semi truck was coming from behind and the vehicle came to a sudden stop within a few seconds. I could not coast and pull into a parking lot. It felt like an emergency brake was turned on or the back wheels locked up. I had to turn into the center turn lane. Vehicle doors would not open and hazard lights would not turn on. Opened manual door handle and forced my way out. Shut door as I ran to safety and the window cracked. I could have been severely injured if that semi hit me from behind and especially if this would have happened on the freeway. Very scary that a car can suddenly shut off like that while driving. After repair I was informed that the 12V battery had failed. They said it’s very rare and they have not seen that happen while the car was driving.
