NHTSA Complaint #11508223 — 2018 TESLA MODEL 3

This is a report of suddent unintended acceleration on a 2018 Model 3 performance with 47,800 miles on the odometer - the first known occurrence on this car. At 50% state of charge, I drove the Tesla on a 10 minute trip and pulled into an underground parking garage with 3 lanes of valet parking. At about 5-10 MPH, the forward collision warning came on as I was driving towards the cones and stop sign. I brought the vehicle to a full stop with the friction brakes (not regenerative braking, which was set to LOW). The drive mode was set to HOLD, which lets the car roll forward but not backwards and doesn't CREEP when foot is off the brake. About 15-30 seconds after coming to a complete stop, my foot was hovering over the brake with maybe slight pressure up to 5%. The car suddenly lurched forward with wide open throttle type acceleration. It has over 450 electric horsepower from 2 motors. The car moved between 2 feet and 5 feet. My passenger noticed and asked what I did, if anything. I did not ever once touch the accelerator. Since my foot was on the brake pedal but not pushing hard on it, I was able to depress it with my foot and stop the car. There was a concrete wall perhaps 25 feet in front of the car. No people were in the front of the car. I was at the stop sign in the garage where valet takes over. I do not know if the car would have kept accelerating if I wasn't able to engage the brakes hard.
