Carrier/rack problems of the 2020 Tesla Model S

On August 18 at 4:30 pm, I had positioned my right front tire against the parking mat riser in my garage. I removed pressure on the accelerator and 'hold' to engaged. I pressed the park button and the car accelerated 3' forward over the parking mat riser into the workbench. I put the car in reverse, and backed up about 2 feet and stopped. The car was in reverse but I mistakenly pushed the stalk down and put it in drive instead of reverse. I backed up, put the car in drive, moved forward and pressed park, again the car accelerated 2' forward into the workbench. I stepped on the brake to hold the car in position. Twice in less than 5 minutes had abruptly accelerated twice over the parking mat riser after putting it in park. I then put the car in reverse, adjusted my seat, and backed up about 6 feet from the workbench, and put the car in park. The car remained stopped. We relocated the parking mat and I parked the car. The car had penetrated about 12 inches into the workbench cabinets. The parking mat had been thrown back 4 feet from its usual position on the floor by the front tire and had to be re-positioned. The damage to the car were two chips in the chrome strip and three dents in the front bumper. One smaller dent above the license plate bracket and two larger deeper dents under it. I had removed but reinstalled front license plate bracket to cover the two large dents. The chrome strip under the Tesla symbol and the entire front bumper will have to be replaced. There are 3 large dents in the front bumper, two are under the license plate bracket. I had removed it but re-installed it to cover the damage. I believe the malfunction was caused by overheated Tesla transmission and tps accelerator sensors were the cause of this incident. There was no driver error involved in this incident. We have parked the 14 new cars we have purchased since 2000 without problem.
