The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Plain-English summary

Mack Trucks, Inc. is recalling certain model year 2012-2013 Mack Granite (GU) trucks manufactured between December 2, 2010, and January 18, 2012. These vehicles are equipped with Bendix ATR-6 traction relay valves.

In extremely cold conditions, these specific relay valves may develop internal leakage. This leakage can cause air pressure to be delivered to the primary or secondary brakes, resulting in continuous brake application. The inadvertent brake application can cause the brakes to overheat and lead to a fire. Additionally, it can cause the wheels to lock up, leading the driver to lose control of the vehicle and increasing the risk of a crash.

Mack will notify owners and provide a temporary repair free of charge until Bendix develops a permanent remedy. Owners may contact Mack Trucks at 1-800-866-1177 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
