was driving my 2022 Mustang Mach-E in "One-Pedal" Whisper mode on. I always drive in that mode because it has a great feature where as soon as I take my foot off the accelerator the car slows down significantly. I feel safer in this mode especially in high traffic or on the freeway. I was very slowly turning into a parking spot in a private parking lot, stepped on brake to put car into Park when the car lurched forward without me touching anything, I had no control of my car no matter how hard I pressed on the brake. My car was driving itself!! when it lurched forward it hit a car parked directly in front of it on its right front side then pushing that vehicle about 2 feet! it did not stop even then, it veered to the right and forward and hit another parked car in the next parking space to the first car that was hit. My car pushed the 2nd car about 2-3 feet before it stopped almost hitting the car parked next to it!! There was an eye witness. This event scared me to death. It was as if someone else was driving my car. I had absolutely NO CONTROL of it. It would NOT STOP. I am soo grateful this happened in a parking lot and not in fast traffic or God forbid the freeway. I would not get back inside my car and never will. We had it towed to a certified repair shop. My car sustained front end & right side front damage. The first car hit sustained right front damage. The 2nd car hit was parked next to the first car hit and sustained right front & right side passenger door damage.
