NHTSA Complaint #11436358 — 2021 RAM 1500

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 remember it's sounding I parked but rear bumper sensors are good I always hear it loudly. I advised them of my intention to file claim for the damage. I can forward emails from dealer & Ram Cutomer Care
