While pulling into what I thought was a parking spot, the left front wheel hit an 8" drop off. Almost immediately after the wheel was back up and level with the other wheels. The vehicle then began surging forward. I hit the brakes but they did not go down. Tried again and the same result. I then hit a hard plastic container and a brick wall. This stopped the vehicle and I was able to put it in park and turn off the engine. Truthfully, once the wheel fell went into the drop off, I had no control of the car. The brick wall has a crack in it and the container is ruined. Toyota Product Liability was called but they have not contacted me. Thankfully the wall did not collapse and no one else was injured. I have pain in left arm and shoulder but hopefully only bruising. The issue has not been confirmed by anyone and I do not know if there were any warnings because I was focused on trying to get the car stopped. There might have been some alarms, I am not sure.
