2021 Ram 1500 backover prevention problems

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.

The contact owns a 2021 Ram 1500. The contact stated that an Over-the-Air update was been performed on the vehicle overnight and the following day the battery was drained and needed to be replaced. The contact drove another vehicle to an independent mechanic and purchased a new battery. After replacing the battery, an error code for a firmware failure was displayed on the instrument panel.
