What this recall covers

NHTSA's campaign record, quoted as published

The defect

Mack Trucks, Inc. (Mack) is recalling certain 2021 Granite, LR, and TerraPro vehicles. The rear drive axle may have the incorrect type of brake cam installed, which could result in inoperative rear axle brakes.

The risk

Inoperative rear axle brakes can increase the distance required to stop, increasing the risk of a crash.

The remedy

Dealers will inspect the brake cams, and incorrect brake cams will be replaced, along with brake shoes, hardware, and wheel seals, as necessary, free of charge. Owner notification letters were mailed on August 10, 2021. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0427.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

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.
