PARKING BRAKE
- The defect
- Mack Trucks, Inc. (Mack) is recalling certain 2008-2019 TerraPro (MRU) and 2019-2022 TerraPro (TE) vehicles. A brake control valve air leak into the attached exhaust hose can create excessive back pressure, causing the parking brake to release unexpectedly.
- What it can cause
- The unexpected release of the parking brake may allow the vehicle to rollaway, increasing the risk of a crash.
- What the dealer does
- Dealers will remove the exhaust tube and fitting from the valve, free of charge. Owner notification letters were mailed February 8, 2022. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0433.
- 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 20,668 vehicles this is a bigger campaign than 84% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2008 to 2022, so the oldest vehicles on it were 13 model years old when the defect was reported to NHTSA.
Mack vehicles have been recalled over the parking brake 6 times before this, most recently in January 2015 as 15V025000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry 5 other recalls published here, the newest being: 26V139000 (engine and engine cooling), 25V030000 (service brakes, air), 24V792000 (service brakes, hydraulic), 22V401000 (steering).
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 December 9, 2021 as campaign 21V953000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
