NHTSA's campaign record, quoted as published
The defect
Mack Trucks, Inc. (Mack) is recalling certain 2026 Mack GR trucks. The brake drum and steer axle combination are incompatible, which may cause a loss of brake function. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
The risk
Reduced brake function can extend the distance required to stop, increasing the risk of a crash.
The remedy
Dealers will replace the steer axle brake drums, free of charge. Owner notification letters were mailed August 27, 2025. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0482.
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
