19V107000

Date: 2019-02-21. Systems: SERVICE BRAKES, AIR.

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."

Consequence: 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.

Remedy: 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.

Do not drive: No. Park outside: No.

16V929000

Date: 2016-12-23. Systems: SUSPENSION.

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.

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. 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.

Remedy: 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.

Do not drive: No. Park outside: No.

16V099000

Date: 2016-02-19. Systems: POWER TRAIN.

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2012-2016 Granite (GU), Pinnacle (CHU, CXU), TerraPro (LEU, MRU), Titan (TD), and LR trucks manufactured from September 1, 2011, through September 8, 2015. The cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may loosen. (excerpt)

Consequence: If he cap nut loosens and falls off, the yoke can separate from the axle input shaft and allow the drive shaft to disconnect, increasing the risk of a crash. (excerpt)

Remedy: Mack will notify owners, and dealers will replace the cap nut. The input shaft threads will be inspected for damage. Any damaged input shaft will be replaced. These repairs will be performed free of charge. An interim notice was sent to owners on April 25, 2016. The recall began on June 7, 2016. Owners may contact Mack customer service at 1-610-709-2131.

Do not drive: No. Park outside: No.

15V522000

Date: 2015-08-17. Systems: ELECTRICAL SYSTEM, SERVICE BRAKES, AIR.

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2013 and 2015 Titan (TD), model year 2014 and 2015 Pinnacle (CHU), and model years 2009-2010, 2012, and 2014-2016 Granite (GU) trucks. The chassis harness and air lines may not be properly clipped to the crossmember, which can allow the cables and air lines to fall and get twisted in the driveline.

Consequence: If the electrical cables and air lines were to fall and get tangled in the driveline, it could affect the electrical system and braking system, increasing the risk of a vehicle crash.

Remedy: Mack will notify owners, and dealers will inspect the vehicles and properly clip the harness and air lines, free of charge. The recall began on September 30, 2015. Owners may contact Mack customer service at 1-800-528-6586. Mack's number for this recall is SC0393.

Do not drive: No. Park outside: No.

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
  • NHTSA's complaints API and bulk file list no complaint for this make, model and model year in this data build.
