On March 31, 2021, I put my car in park and was readying myself to get out and enter a store. I leaned over to put on my masks and was alarmed to find that my vehicle had moved forward into the rear of another vehicle. I didn't really feel it moving, so I had no idea until it had rolled into the car in front of me. Earlier this week, I heard a squeeky noise while driving for a short period of time, but then it disappeared. I have had other problems with the electrical, passenger headrest deploying, exterior trim blowing off and rear gate failing to open. A couple of times, the gear did not seem to properly shift, but this is the first time that it has moved on its own. The damage to my vehicle and the other vehicle was slight since the car was not moving at a great speed and was stopped before traveling a great distance, but a car suddenly taking off on its own is quite dangerous. I have less than 50, 000 miles on my vehicle.
