When slowly finishing my entry into a parking spot and braking the car suddenly accelerated to a high speed and bolted over the curb with a planter zone into another parked car directly facing my parking lane hitting the front passenger side. My car was still accelerating and hit another car to the left of the first parked car, hitting it in the rear driver side door. My car kept going until I was finally able to get the brake to work and it stopped just before another parking lot curb with planter zone. As far as I can tell the brake and or accelerator malfunctioned dangerously and suddenly. It could also have been a malfunctioning TPS (throttle positioning sensor). I would like my car inspected to determine what caused this malfunction. While everyone involved said they felt fine. One person, in the first car hit, was sitting in the driver seat, luckily no one was in the front passenger seat. That driver said she was ok. The second car was unoccupied. This dangerous incident had no warnings or symptoms prior to the accident. My online research shows that there was a recall that included my make and year for sticky pedal, floormat, and deformed accelerator cable housing. These can cause unintended acceleration or unresponsive pedal. According to the Toyota website my VIN has no outstanding recalls though. I would like my car checked out because any recall repair, if done, may not have been done thoroughly enough to prevent the collision I experienced on September 28, 20
