What's wrong, in plain English
On certain 2021 Volvo VNL, VNR, VAH, and VHD trucks, small internal jaws called collets, used with a brass fitting on the truck's pneumatic pass-through plate, may have been damaged during leak testing. Because of this damage, the brass fitting can come apart from the pass-through plate while the air brake system is under pressure. If this happens in the park brake air line, the pressure that keeps the spring-loaded park brakes released can be lost, causing the park brakes to apply on their own.

- Summary
- Volvo Trucks North America (Volvo Trucks) is recalling 2021 VNL, VNR, VAH, and VHD vehicles. The collets (internal jaws) for the brass fitting inserts used in the pneumatic pass-through plate may have been damaged during leak testing. As a result, the brass fitting may completely release the air brake line from the pass-through plate while under pressure. If this occurs on the park brake circuit, signal pressure that holds off the mechanical spring in the park brake chambers will be lost allowing the park brakes to apply.
- Safety risk
- If the park brakes apply unexpectedly, the driver may lose control of the vehicle, increasing the risk of a vehicle crash.
- Remedy
- Volvo Trucks will notify owners, and dealers will inspect the air brake line for proper engagement of the fitting in the pass-through plate, free of charge. The recall is expected to begin January 31, 2021. Owners may contact Volvo Trucks customer service at 1-800-528-6586. Volvo Trucks' number for this recall is RVXX2006.
