3 recalls.

23V600000

Date: 2023-08-25. Systems: EXTERIOR LIGHTING.

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."

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

Remedy: 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.

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.

16V098000

Date: 2016-02-19. Systems: STEERING.

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2016-2017 Granite (GU) and TerraPro (MRU) trucks manufactured from November 9, 2015, through January 19, 2016. The affected trucks may be missing a roll pin to secure the upper steering yoke to the steering shaft.

Consequence: If the roll pin is missing, the steering shaft may disconnect from the yoke, resulting in a complete loss of steering and increasing the risk of a crash.

Remedy: Mack will notify owners, and dealers will inspect the vehicles and replace the steering shaft if the roll pin is missing, free of charge. The recall began on April 1, 2016. Owners may contact Mack customer service at 1-610-709-2131. Mack's recall campaign number for this recall is SC0400.

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.
