2021 RAM 1500 Back Over Prevention Warnings Problems

Using the self parking feature, the vehicle had controlled itself, with my intervention when prompted. It had backed up perpendicular into the parking space, miscalculated the parking job and smashed the side mirror into a nearby trucks mirror. It had then began to speed up to what felt like about 15 or 20 mph, with no time to react or brake, and smashed into the concrete pole behind us. The automatic braking failed to react, the vehicle failed to recognize the objects behind us, and miscalculated the parking distance from other vehicles. After the rear of the truck has been severely damaged, it did not throw any errors or codes. It simply acts as if nothing happened. It never prompted me to stop, or switch gears. It had sped up on its own to a dangerous speed. It had a mind of its own. Dangerous and unsafe.

I drove in to park, I pulled more to the right to give way to pulling out going car I did not notice 3-short protective steel pole that caused damage to running board & scratches on front passenger door. Had the early warning device sensor of side bumper sounded,Icould have avoided it. I Tested, even the front sensors were not working not even warning lights in the instrument screen. The following day I reported to Dealer's Service Mgr. & I kept testing it for several days & The Customer Care of Ram denied responsibility that it driver' negligence. My truck has several history of failed electronics devices the dealer corrected except this one because it's back sounding again. This Early Warning Device Sensors is accident preventive. It comes on & off like the backing camera & others. It normally sounding loud as I park but prior to incident, I don't...

The truck previously shut off twice during a left and then a right turn. That was around 120 and 200 miles on the truck, respectively. Only other issue was during a turn the radio changed channel autonomously. Today with 1700 mile I backed it up and then put it in drive. The truck shut off and kicked every fault code on the truck. When trying to start it back it would not turnover and kept turning things on and off like the electrical system was possessed.
