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.

I was driving, accelerating into heavy traffic, and just about to go under an overpass (sunny day), when the Forward Collision System activated and hard-braked me to a stop, nearly causing an accident with the vehicle behind me. Although there was a car in front of me, it was not close and there was no danger of a collision (it was accelerating). Worse, no warnings came from the system until it started braking. This has happened several times, always in heavy traffic, and always on a underpass or lower bridge deck. I'm going to have to turn this system off, because I don't want to get rear-ended. My FCS is on the medium setting.
