SERVICE BRAKES, AIR:DRUM
- 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."
- What it can cause
- Reduced brake function can extend the distance required to stop, increasing the risk of a crash.
- What the dealer does
- 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.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

How this campaign compares
At 36 vehicles this is a small campaign: 81% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published are as large or larger. The middle campaign on file covers 472. It covers one model year, 2026, and the defect was reported to NHTSA in 2025, at or before the oldest model year it covers — as current as a recall gets.
Mack vehicles have been recalled over the service brakes, air 32 times before this, most recently in January 2025 as 25V030000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry one other recall published here: 25V352000 (equipment).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by Mack Trucks, Inc. with NHTSA on July 29, 2025 as campaign 25V495000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
