NHTSA Complaint #11477897 — 2020 JEEP GLADIATOR

My truck malfunctioned at an automatic car wash. It has approximately 54k miles. I had no warning lights or system alerts on vehicle or Uconnect app. I stopped in the parking lot & put the Gladiator in Park, I left the ignition on. I got off truck & got a towel to clean interior.There are several spaces to vacuum. I put the vehicle in DRIVE to move forward & out of the way of a patron that was going to reverse out. In DRIVE, I pushed the gas pedal in a slight & normal way. The truck REVERSED in DRIVE position. It accelerated to an unknown speed, it felt constant. I pushed break with foot I pushed D with. Right foot. The breaks didn’t work. I tried breaking several times during incident, it was approximately 10 seconds. I didn’t have time to use e- break. I don’t believe back up camera was displayed. I concentrated on physically looking at surroundings & steering. I avoided hitting 1 car, a SUV & a brick wall. The truck made contact with around 4 trees & a sign. The damage was mainly to L side. There’s damage to R side & R back tire had a bulge on it. I went over a concrete, grassy area & felt the impacts of front & back ends going over it & landing. I went over another concrete curve & hit a tree at an angle around the middle of front L cab. The impact caused the car to bounce forward. It didn’t move. I put the truck in Park from D position. I pushed off button. I couldn’t get out of truck of driver side door it’s damaged. 1 witness & lady from suv stopped to check on me. I called police to crash site. He noted witness & lack of break marks. Roadside service wait was long, officer called one. I made a report to Uconnect that evening. They gave me a case # told me they’d move vehicle to a dealer, inspect, analyze & call me. I’ve called, recorded calls & told case was elevated to higher level & no info can be given to me. They refused to tell me where car was, if inspected, warranty info, or what malfunctioned. My ribs, clavicles, r shoulder hurt for a month.
