NHTSA campaign 14V553000
Hazard
Mack Trucks, Inc. (Mack) is recalling certain 2015 CHU, CXU, and GU trucks manufactured June 4, 2014, through June 18, 2014. In the affected vehicles, the bolts that attach the seat belt to the seat frame may not have been torqued to the required specification. This could cause the bolts to loosen over time, allowing the seat belt to detach.
Consequence
If the seat belt detaches from its mounts, the seat belt would fail to properly restrain to the seat occupant, increasing the risk of injury in the the event of a crash.
Remedy
Mack will notify owners, and dealers will tighten the bolts to the required specification, free of charge. The recall began in October 2014. Owners may contact Mack customer service at 1-800-528-6586. Mack's number for this recall is SC0383.
