My concern is a potential unintended acceleration forward as. I was. parking vechicle. Sudden burst of speed, went thru shrubbery and off a 2 foot wall. Felt as if we were taking off a runway in a plane. Car went nose up over the wall and then dropped into a neighbor yard digging a divot, ripping rear left fender and bumper with some undercarriage problems. My spouse and I were seatbelted and not injured. I can not recall any safety warning until car stopped and then do recall a message being on dash but cannot presently recall what it said. Vehicle currently being worked on at collision center where Insurence Appraisor gave go ahead with estimate to repair damages
