2025 Ram 2500 lighting problems

Purchased above vehicle on 7/12/25. Was advised no towing for 1st 500 miles. At 712 miles, I hooked my fishing boat up to the truck to go fishing. Initially, truck did not recognize my boat trailer lights (marker and tail lights). My previous truck was a 2023 Ram 2500 rebel that never had an issue with connecting my boat trailer electrical system. All lights worked as should. I still have the same boat trailer as previous(2020 shore lander trailer with led lights).

The contact owns a 2025 Ram 2500. The contact stated that the message "Service Trailer Lighting" was displayed while driving. The contact received notification of NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System); however, the part to do the recall repair was not yet available. The local dealer and several other dealers were contacted and informed that the recall part was not available because only one part could be ordered every two weeks. The vehicle was not diagnosed or repaired.
