NHTSA Complaint #11619723 — 2018 TESLA MODEL S

I pulled into a driveway on a one lane road (due to construction) to allow a car traveling downhill to pass so they would not have to back up. I had come to a complete stop in the driveway with the car in drive. As I started to put the car in reverse it surged forward at a high rate of speed crashing into my neighbor's garage, tearing the door completely down pushing the door into the garage and my car entering the garage at least 15 feet hitting the car that was parked inside and pushing it with such force that the front end of the vehicle struck the garage cabinets tearing them down. My air bag did not deploy nor did the automatic braking system engage, it just sped up as it was doing the damage. The car has been deemed a total loss by my insurance company but i don't want this report to go unnoticed. To my knowledge the insurance company has not inspected the computer on the vehicle. I'm not sure how they will investigate this occurrence. I feel strongly that this was a malfunction with my car. The message that showed immediately was "driver assist unavailable", I have NEVER used driver assist.
