NHTSA Complaint #11710416 — 2021 TESLA MODEL Y

I parked my Tesla vehicle in a friend’s driveway. When I returned and opened the driver’s door, I entered the vehicle and attempted to put it into Drive. At that point, the vehicle display went completely blank and the vehicle became inoperable. I then attempted to open the door from inside the vehicle, but the door would not open and I was unable to exit the car. I was effectively locked inside the vehicle. I contacted Tesla customer support and remained on the call for approximately 1.5 hours before receiving assistance. Tesla customer support confirmed that the issue was caused by failure of the 12-volt battery. At the time of the incident, the outside temperature was below 0 degrees centigrade. The incident occurred in Cedar Rapids, Iowa. There was no prior warning or notification from the vehicle or the Tesla mobile app indicating that the 12-volt battery was at risk of failure. The failure resulted in loss of vehicle function and inability to exit the vehicle, creating a serious safety concern.
