19V616000

Date: 2019-08-21. Systems: SUSPENSION.

Defect: Mack Trucks, Inc. (Mack) is recalling certain 2015 Pinnacle (CXU) vehicles equipped with Meritor FF967 Non Drive Front Steer Axles. The axles missed the heat treating operation during manufacturing, reducing their strength and possibly causing the axle beams to fracture.

Consequence: Fracture of the axle beam can cause a loss of vehicle control, increasing the risk of a crash.

Remedy: Mack will notify owners, and dealers will inspect and replace the axles as necessary, free of charge. The recall began September 27, 2019. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0419.

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. Mack's recall campaign number for t (excerpt)

Do not drive: No. Park outside: No.

15V521000

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

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2013-2015 Pinnacle (CXU) trucks manufactured from October 3, 2012, through February 18, 2014 and equipped with Meritor air disc brakes. In the affected vehicles, the brake chambers may have been incorrectly mounted resulting in internal contamination of the air brake calipers. (excerpt)

Consequence: Contamination of the calipers may cause a loss of brakes on one wheel, lengthening the distance required to stop the vehicle, increasing the risk of a crash. (excerpt)

Remedy: Mack will notify owners, and dealers will inspect the disc brake caliper and brake chamber to determine if the washers are located in the correct position. If the washers are in the correct position, no further action is required. If the washers are not located in the correct position, replacement of the disc brake caliper and brake chamber will be performed and the addition of two washers per b (excerpt)

Do not drive: No. Park outside: No.

15V139000

Date: 2015-03-11. Systems: TRAILER HITCHES.

Defect: Mack Trucks, Inc (Mack) is recalling certain model year 2012-2015 CXU trucks manufactured February 4, 2011, to December 23, 2014, and equipped with an air release fifth wheel latch. The affected vehicles have a switch to release the fifth wheel latch that may invertently be pushed and cause the trailer to unintentionally disconnect from the tractor after the parking brake has been released.

Consequence: An inadvertent decoupling of the trailer from the tractor may increase the risk of a crash.

Remedy: Mack will notify owners, and dealers will install a secondary action that operators will need to activate before the fifth wheel will release, free of charge. The recall began on May 6, 2015. Owners may contact Mack customer service at 1-800-528-6586. Mack's number for this recall is SC0390.

Do not drive: No. Park outside: No.

15V057000

Date: 2015-02-03. Systems: SERVICE BRAKES, AIR.

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2014-2015 CXU trucks manufactured June 1, 2013, to November 28, 2014. These trucks may be equipped with an 88 liter air reservoir for the brakes instead of a 96 liter air reservoir. 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 Feder (excerpt)

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

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. (excerpt)

Do not drive: No. Park outside: No.

15V025000

Date: 2015-01-22. Systems: PARKING BRAKE.

Defect: 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. The affected actuators may have an incomplete attachment of the internal rubber diaphragm to the actuation mechanism of (excerpt)

Consequence: If the diaphragm is not completely attached, there may be internal leakage from the service section past the diaphragm, potentially trapping air pressure in the parking brake section. This air pressure in turn, if not vented, may prevent full release of the actuator unit, and may induce brake drag and may result in overheated wheelend service brakes, increasing the risk of a fire. (excerpt)

Remedy: Mack will notify owners, and dealers will inspect the brake actuator and replace, as necessary, free of charge. The recall began March 20, 2015. Owners may contact Mack customer service at 1-610-709-2131. Mack's number for this recall is SC0387. (excerpt)

Do not drive: No. Park outside: No.

14V738000

Date: 2014-11-20. Systems: ENGINE.

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2015 CXU and GU trucks manufactured January 1, 2014, to August 20, 2014. The affected vehicles contain an incorrectly wired Automatic Shut-down Protection System, which may not operate as expected.

Consequence: If the Automatic Shut-down Protection System does not operate as expected, the operator may be unable to control the increase in the engines rpms, increasing the risk of engine failure and vehicle fire.

Remedy: Mack will notify owners, and dealers will inspect the system for correct operation and repair if necessary, free of charge. The recall began on January 16, 2015. Owners may contact Mack customer service at 1-610-709-2131. Mack's number for this recall is SC0386.

14V737000

Date: 2014-11-18. Systems: STEERING.

Defect: Mack Trucks, Inc. (Mack) is recalling certain model year 2015 CHU and CXU trucks manufactured from March 31, 2014, through June 26, 2014. In the affected vehicles, the collars that prevent the ball sockets from backing out of the tie rod may have been incorrectly positioned. This may allow the ball sockets to come loose.

Consequence: If the ball sockets come loose from the tie rod, a complete loss of steering may result, increasing the risk of a crash.

Remedy: Mack will notify owners, and dealers will inspect and re-position the collar if necessary, free of charge. The recall began on January 20, 2015. Owners may contact Mack customer service at 1-800-528-6586. Mack's number for this recall is SC0385.

Do not drive: No. Park outside: No.

14V553000

Date: 2014-09-11. Systems: SEAT BELTS.

Defect: Mack Trucks, Inc. (Mack) is recalling certain 2015 CHU, CXU, and GU trucks manufactured June 4, 2014, through June 18, 2014. In the affected vehicles, the bolts that attach the seat belt to the seat frame may not have been torqued to the required specification. 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.

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.
