On August 25, 2025, I was in a crowded Trader Joe's parking lot using the vehicle's FSD parking feature. The vehicle was moving backward into a parking position. A stationary vehicle was in the area. Instead of detecting the other vehicle and stopping, the Tesla kept backing up and made contact with the stationary vehicle. The other vehicle was not moving, and there was enough room for the Tesla to park without contact. I do not remember the exact positioning or direction because of the time that has passed. I did not receive a warning that prevented the contact. I reported to Tesla that the vehicle appeared not to detect the stationary vehicle, but I did not receive an inspection result or written technical finding. I do not have an expert determination of the cause. I am asking NHTSA to review this as a possible FSD parking, parking-collision-warning, or automatic-emergency-braking safety defect.
