What's wrong, in plain English
Some 2025-2026 Volvo VNL trucks have a body control module for the trailer lighting system that was not manufactured correctly. Because of this manufacturing problem, when the truck is towing a trailer, the trailer's tail lights and turn signals may fail to come on the way they are supposed to, even when the driver activates them.
What you should do
2. Contact a Volvo Trucks dealer, or call Volvo Trucks customer service at 800-528-6586.
3. Replacement of the trailer body input/output module is free.
