2017 Mack Granite (Gu) recalls

Defect: Mack Trucks, Inc. (Mack) is recalling certain 2015-2023 GU and GR vehicles. The turn signals may be positioned incorrectly, reducing their visibility. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment.".

Why it matters: Low turn signal visibility may not alert other drivers to a turning vehicle, increasing the risk of a crash.

Dealers will add additional turn signal lighting, free of charge. Owner letters were mailed September 25, 2024. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0448.

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.
