Greensboro, North Carolina — Federal safety regulators have flagged critical equipment defects across recent model year heavy-duty rigs, prompting major recall actions from two major truck manufacturers. The National Highway Traffic Safety Administration announced that thousands of Volvo and Mack commercial vehicles built for the 2025 and 2026 model years require immediate dealer intervention to fix faulty lighting systems and potential door latch failures. For an OTR truck driver putting in long hours across interstate corridors, unexpected equipment malfunctions create severe safety hazards during night operations or severe weather.
Volvo Trucks North America is recalling more than 2,000 VN commercial vehicles from the 2025 and 2026 production cycles due to a fault within the trailer body control system. A defective body control module can cause trailer lighting arrays to cut out entirely while hauling loads, leaving following traffic blind to braking and lane changes. The same electrical defect impacts more than 150 Mack Pioneer trucks from the same model years. Volvo documented 28 field cases and 204 warranty claims associated with 176 individual units, though no crashes or injuries have been formally linked to the electrical failure.
Official owner notifications are scheduled to hit mailboxes starting November 17, 2025, and dealerships for both brands will swap out the faulty trailer body input and output modules at zero cost. Volvo has designated recall number RVXX2507, with NHTSA tracking the action under reference 25V621. Mack customers can reference recall number SC0484 and NHTSA number 25V622. Fleets with drivers on the road must check their unit numbers immediately to coordinate service and maintain compliance with federal safety mandates.
What This Means for Drivers
CDL-A drivers and independent owner-operators handling affected rigs must remain vigilant for dashboard warnings indicating a loss of communication with the trailer body module. When trailer tail lights or turn signals drop out mid-trip, commercial drivers face an immediate risk of rear-end collisions and heavy fines during roadside inspections. Fleet managers and company drivers operating these specific 2025 and 2026 models need to schedule dealership service appointments right away to avoid downtime and maintain safety standards across their routes.
Industry Reaction
Component failures involving crucial safety systems routinely draw heavy scrutiny from federal regulators and commercial fleet operators alike. Keeping electrical and braking systems reliable is essential for maintaining strict compliance and avoiding costly roadside violations. As major trucking companies hiring across the country look to upgrade equipment and attract skilled operators, reliable maintenance records and rapid manufacturer recalls remain vital for daily operations.
Key Points
