4 recalls.
Date: 2014-11-18. Systems: STEERING.
Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2015 CHU and CXU trucks manufactured from March 31, 2014, through June 26, 2014. In the affected vehicles, the collars that prevent the ball sockets from backing out of the tie rod may have been incorrectly positioned. This may allow the ball sockets to come loose.
Consequence: If the ball sockets come loose from the tie rod, a complete loss of steering may result, increasing the risk of a crash.
Remedy: Mack will notify owners, and dealers will inspect and re-position the collar if necessary, free of charge. The recall began on January 20, 2015. Owners may contact Mack customer service at 1-800-528-6586. Mack's number for this recall is SC0385.
Do not drive: No. Park outside: No.
Date: 2014-09-11. Systems: SEAT BELTS.
Defect: 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.
Do not drive: No. Park outside: No.
Date: 2014-09-09. Systems: FORWARD COLLISION AVOIDANCE.
Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2013-2015 CXU and 2014-2015 CHU trucks manufactured August 23, 2012, through June 27, 2014, and equipped with adaptive cruise control. Due to a software error, the affected vehicles may not provide visual or audible alerts to the driver warning them that an obstruction in the road was detected.
Consequence: If the driver is not warned of something being in the truck's path, there is an increased risk of a crash.
Remedy: Mack will notify owners, and dealers will reprogram the vehicle control unit, free of charge. The recall began on September 30, 2014. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0381.
