STEERING:HYDRAULIC POWER ASSIST:PUMP
- The defect
- Mack Trucks, Inc. (Mack) is recalling certain 2021 Granite and LR vehicles. A machining defect may cause pressure to build in the power steering pump and break the shaft seal, resulting in a loss of power steering assist.
- What it can cause
- A loss of power steering assist increases the risk of a crash.
- What the dealer does
- Dealers will replace the power steering pump, free of charge. Owner notification letters were mailed on December 10, 2021. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0432.
- NHTSA's note
- 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.
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 79 vehicles this is a small campaign: 73% 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, 2021, and the defect was reported to NHTSA in 2021, at or before the oldest model year it covers — as current as a recall gets.
Mack vehicles have been recalled over the steering 28 times before this, most recently in April 2021 as 21V293000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry 8 other recalls published here, the newest being: 25V666000 (seat belts), 24V792000 (service brakes, hydraulic), 24V773000 (tires), 23V600000 (exterior lighting).
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 November 3, 2021 as campaign 21V856000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
