Two major truck manufacturers are facing recalls this fall as safety regulators flag defects in both lighting systems and door latches. According to the National Highway Traffic Safety Administration (NHTSA), the recalls affect thousands of Volvo and Mack vehicles built for the 2025 and 2026 model years.
Lighting Malfunctions on Volvo and Mack Trucks
Volvo Trucks North America is recalling more than 2,000 VN trucks from the 2025 and 2026 model years after uncovering a fault in the trailer body control system. The defect, traced to an improperly manufactured body control module, can cause trailer lights to stop working when the truck is towing.
Drivers may notice the issue if their dashboard displays a pop-up warning that communication has been lost with the trailer body input and output module. If the trailer’s tail lights or turn signals fail, surrounding motorists may not see the truck braking, stopping, or changing lanes, which raises the risk of collisions.
The same lighting issue may also affect more than 150 Mack Pioneer trucks built for model years 2025 and 2026. Volvo reported 28 field cases and 204 warranty claims connected to 176 trucks, though there have been no confirmed crashes or injuries tied to the defect.
Both Mack and Volvo dealers will replace the trailer body input and output module free of charge. Owners will begin receiving official notifications by mail on November 17, 2025.
- Volvo owners can contact customer service at 800-528-6586 and reference recall number RVXX2507.
- Mack owners can call 800-866-1177 with recall number SC0484.
- NHTSA reference numbers are 25V621 for Volvo and 25V622 for Mack.
Door Latch Recall on Volvo VN Trucks
In a separate action, Volvo Trucks has also identified a potential hazard with interior door latches. Over 4,000 VN trucks from the 2026 model year are being recalled because an incorrectly installed latch cable on the interior handle could keep the door from opening.
A jammed latch poses the risk of trapping occupants inside the cab, creating a safety hazard in emergencies. So far, Volvo has received 17 field reports, but no incidents or injuries. The company estimates that less than half a percent of the affected vehicles are actually defective.
Dealers will repair the issue at no cost, replacing both the latch cable and the pivot clip. Owners of affected vehicles will be contacted by mail beginning November 17, 2025.
- Volvo customer service can be reached at 800-528-6586, recall number RVXX2508.
- NHTSA has assigned this recall the number 25V620.
What Truck Owners Should Do
Drivers operating affected Volvo or Mack trucks are urged to pay close attention to their recall notifications and schedule service as soon as possible once letters arrive. Even though no injuries have been reported, both lighting failures and jammed doors present serious safety risks if left unaddressed.
For additional information, truck owners can search recall numbers directly through NHTSA’s online recall database or contact the manufacturers’ customer support lines.
