2017 Mack Pinnacle (Chu) recalls

Defect: Mack Trucks Inc. (Mack) is recalling one 2014 Pinnacle (CXU) vehicle and certain 2018-2019 Mack Anthem (AN) vehicles equipped with air brake supply tanks that have an air volume amount ranging from 70% to 96% of the amount required by the regulation. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems.".

Why it matters: The undersized air brake supply reservoir may provide an insufficient air supply to properly operate the brakes during repetitive brake applications, reducing braking performance and increasing the risk of a crash.

Mack will notify owners and dealers will add an air tank to the affected vehicles, free of charge. The recall began April 10, 2019. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0417.

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2012, 2014-2015 and 2017 Granite (GU), 2012-2017 Pinnacle (CHU, CXU), and 2013-2015 and 2017 Titan (TD) trucks manufactured January 7, 2011, to September 29, 2016. The affected vehicles were built with front wheel hubs that cannot support the gross axle weight rating of the front axle.

Why it matters: 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. Because of this, the driver may lose control of the vehicle or parts may be dropped on the road, increasing the risk of a crash.

Mack will notify owners, and dealers will replace the hub assemblies, free of charge. The recall began on February 16, 2017. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0406.

The tires on the affected vehicles may have cured improperly causing an incomplete adhesion, possibly resulting in a partial tread separation.
