On Saturday December 29th, while driving on a smaller regional highway I heard noise which seemed to be coming from the truck. As I looked into the rear view mirror I watched in horror the tonneau cover take flight and slam into the roadway behind me. Thankful, the cars noted to my right were not directly behind me, as it would have certainly caused a serious accident. I did circle back to locate the remains of the tonneau cover and still have it in my possession for evaluation. I contacted the dealer inquiring if there had been any recalls or safety issues or concerns regarding the tonneau cover that came with the 2022 custom build RAM truck. In that email I also who I should be in contact with to discuss the replacement of the cover and repairs to my truck for the failure of the cover. In my email to the dealership, I attached photos of the cover, damage and the odometer for documentation.To date yet to hear back from the dealer by phone or email I emailed the general sales manager at the dealership on Janurary 8th.
