Warnings problems of the 2021 Subaru Outback

I was already parked in a spot in a public parking lot. I tapped the accelerator pedal to move the car a few inches. The vehicle responded by violently accelerating, hitting a vehicle directly in front of me in another parking space. I applied my brake but the car would not stop. The force of the acceleration pushed the car out of the it's spot and it hit a curb and tree appox 30 ft away. In defensive move I turned my wheels to the right and continue to try and brake. This caused my car to hit the car on the right side of me. Property damage occured. No injuries. Vehicle defect.

I have had this vehicle since @ 6/30/21, under 4,000 miles. Sometimes when I'm driving, the car will suddenly brake or lurch when I am not near another object or person. I drove down the highway once when this happened and it was very concerning. I have also been in the middle of an intersection when this occurred, as I was turning left. It has happened approximately 10 other times since I've had the vehicle. Today it happened and a truck was behind me; thankfully I did not get hit. I brought this into the dealereship twice and they claim there is nothing wrong with the car. There is definitely something wrong with the car; it's dangerous. My car is available for inspection upon request. I and others are at great risk for an accident. I remember flashing lights on a few occasions, not today. When I went online to check for recalls, I noticed many other Subaru owners having the same issues.
