NHTSA Complaint #11709850 — 2025 RAM 3500

On 12/15/2015 my 2025 RAM 3500 at 30180 miles had a Trailer communication problem with Running lights on trailer not working. It was sent to RAM dealership in Albany, OR. They diagnosed that the Integrated Trailer control module was at fault. It was replaced and passed working operation, On 12/30/25 Ram was connected to Trailer. The Trailer seemed to be fully operational and about 5 miles down the road the Running lights stoped working again. I had trailed tested and no electrical issues were found. Had 7 way trailer pin in Ram tested and showed 12V power but no out for Running lights. Schedule another appointment to go to Wilson Ram in Corvallis, OR. The ran another diagnostic test on it and found it was fully operational and they could not duplicate the issue I was having. As the Ram gets closer to warranty being expired and I use this Ram for business hauling a trailer that it’s a safety issue when Running lights don’t work. I feel that RAM needs to address this problem sooner than later. I will be getting my Ram back on 01/09/2026 and We’ll connect to Trailer once again and see if itheir is no issues this time. I feel a recall should be in place to resolve the problem with a new harness, brake controller and all modules for Trailer Tow system. As a consumer having down time due to having to go back for diagnostics all parts should be replaced if one part of the system has failed. Is it not only a safety issue it can impact business owners who Need their Vehicle to operate their business. Thank you for taking the time and I will submit follow up if these trailer issues continue.
