2026 Mack Granite GR (4): Service Brakes, Air recall
NHTSA campaign 25V495000 · 36 units potentially affected · filed Jul 29, 2025
What's wrong
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."
Why it matters
Reduced brake function can extend the distance required to stop, increasing the risk of a crash.
The fix
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.
