The affected vehicles were built with front wheel hubs that cannot support the gross axle weight rating of the front axle.

Consequence: Overloaded front wheel hubs can result in premature failure of the hubs, bearings, and the related components, which can cause the front hub assembly to separate from the front axle.

The lower volume of air may result in increased distances being needed to stop the truck. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 121, "Air Brake Systems."

Consequence: If the truck unexpectedly requires extra distance to stop, there is an increased risk of a crash.

Remedy: Mack will notify owners, and dealers will install a larger air brake reservoir tank, free of charge. The recall began April 1, 2015. Owners may contact Mack customer service at 1-800-528-6586. Mack's number for this recall is SC0389.

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.

Mack Trucks, Inc. (Mack) is recalling certain model year 2015 and 2016 CXU and LEU trucks manufactured May 20, 2014, to March 24, 2015, equipped with certain Haldex Life Seal Type 30/30 Long Stroke Air Brake Actuators manufactured from January 9, 2014, through February 3, 2015.
