NHTSA Complaint #11547546 — 2023 TESLA MODEL Y

I was driving at a very slow speed of 1 mile per hr as I entered into the Kohls complex in Pleasanton ca. Then as I was pulling the car to a parking spot, all of a sudden I felt the car accelerated on me. My foot was always on the break and I pressed the break but the car still accelerated at a speed I had no control and it went over the parking bump and hit 2 cars that was parked opposite. I felt out of control and scary because the car was not doing as intended, to stop when pressed the break. I then pressed the park button. Then I also reversed because the car was not stopping. There was totally 4 cars damaged including my car. 2 opposite and 1 parked side of me. I could feel the sudden acceleration in the car and out of control feeling. Luckily there were no people in other car so no one was hurt. I was also not hurt. - Not sure what malfunction happened , but the break in that instant of time was not acting as it should for few seconds. Yes, the car is available for inspection - My safety was at risk as the car was no behaving the way it should and I got scared as to what would happened next. Since there were no people in the other car, there was no risk. but if there were they probably would have got hurt. - I reported the issue to Tesla center. They said they will look but never heard back anything from them . - None of them has inspected the vehicle yet. - No warning signs were there. after it hit i could hear the beep
