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.

Risk. The unexpected release of the parking brake may allow the vehicle to rollaway, increasing the risk of a crash.

Remedy. 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.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
