Pulled into parking space. Applied brakes and came to a complete stop. Could hear engine revving up.. Thought ok, that gas pedal seem to be pressed. Look at my foot wasnât pressing the pedal. Looked at floor mats. It was laying flat on floor, not manipulating the pedal. I thought whatâs happening? And lifted foot off brake ever so slightly and car jumped 6 inch high curb and hit the building.. Pretty hard. Caused structural damage to the wall. I went to the hospital, driven by husband. Swelling of my right leg on the shin. Released and told to stay off leg for few days, no fractures.After doing research, It seems other jeep riders have had this experience. I have no idea how fast the jeep was going.
