Volvo and Mack Truck Recalls Over Risky Light Failures

New Truck Recalls Affect Volvo and Mack Models Over Trailer Light Failures

Two new truck recalls have been announced by the National Highway Traffic Safety Administration (NHTSA) involving Volvo and Mack trucks from model years 2025–2026. Both recalls address a defect that may cause trailer lights to fail, creating a safety hazard for commercial drivers and other motorists.

Overview of the Truck Recalls

On September 18, 2025, NHTSA published two separate recalls:

• Recall 25V621000 — Volvo Trucks North America
• Recall 25V622000 — Mack Trucks, Inc.

Each recall covers a specific truck model and year, but both involve the same issue: a body control module defect that may prevent trailer tail lights and turn signals from illuminating properly.

When the trailer lighting fails, other drivers may not see the truck’s movements, increasing the risk of rear-end collisions or lane-change crashes.

Volvo Trucks Recall Details 

• Manufacturer: Volvo Trucks North America
• Models Affected: 2025–2026 Volvo New VN
• Component: Exterior Lighting
• Units Affected: 2,307 trucks
• NHTSA Campaign Number: 25V621000

The defect stems from an improperly manufactured body control module. When towing a trailer, the trailer lights may fail to illuminate. This can make it difficult for nearby drivers to detect when the truck is braking or turning.

Remedy and Timeline

Volvo dealers will replace the trailer body input/output module free of charge.
Owner notification letters are scheduled to be mailed on November 17, 2025.

Truck owners can contact Volvo Trucks customer service and reference the recall number. VINs are searchable on NHTSA.gov.

Mack Trucks Recall Details 

• Manufacturer: Mack Trucks, Inc.
• Models Affected: 2025–2026 Mack Pioneer (PR)
• Component: Exterior Lighting
• Units Affected: 156 trucks
• NHTSA Campaign Number: 25V622000

This recall mirrors the Volvo issue. When towing a trailer, the lights may not illuminate because of a faulty body control module.
The defect can reduce visibility and increase crash risk in dark or low-visibility conditions.

Remedy and Timeline

Mack dealers will replace the trailer body input/output module at no cost.
Owner notification letters will also be mailed on November 17, 2025.

Truck owners can contact Mack customer service and refer to the recall number. VINs are available for lookup on NHTSA.gov.

Why These Truck Recalls Matter

Trailer lighting plays a vital role in highway safety. Without functioning brake lights or turn signals, nearby motorists can’t anticipate a truck’s movements. For long-haul drivers, this failure can create serious risks on interstates, during night driving, or in poor weather.

Even though the issue affects a limited number of vehicles, fleet operators and owner-operators should check their trucks promptly. Addressing these truck recalls early prevents compliance issues and potential liability.

What Drivers Should Do Now 

1. Check VINs — Visit NHTSA.gov/recalls starting September 25, 2025 to confirm if your truck is affected.
2. Contact Dealers — Schedule a free module replacement with an authorized Volvo or Mack dealer.
3. Follow Notifications — Watch for recall letters expected November 17, 2025.
4. Document Repairs — Keep proof of recall service for compliance and recordkeeping.

Summary

Both Volvo New VN and Mack Pioneer (PR) trucks from model years 2025–2026 are part of recent truck recalls due to inoperative trailer lighting caused by defective body control modules. Owners should verify their VINs, schedule repairs, and ensure lighting systems work properly to stay safe and compliant.
