Parking brake
Problem: 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.
Fix: 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.
Electrical system
Problem: Mack Trucks is recalling certain model year 2008-2009 GU, LEU, and MRU trucks, manufactured from December 12, 2007, through May 8, 2008 and equipped with a certain focal mounted retarder control box. The control box may lose its electrical ground.
Risk: If the control box loses ground, it may have localized overheating. This could lead to a vehicle fire.
Fix: All affected vehicles were sold to one customer that has already been notified. An official owner notification letter will be mailed to the one customer in early November 2012.

Fix: Dealers will install a relay harness to prevent the mirror switch from overheating. They will also inspect the mirror switch and if signs of overheating are shown, replace that switch. All inspections and repairs will be performed free of charge. The safety recall began on june 30, 2011. Owners may contact mack trucks at 1-800-866-1177.
