2017 MACK PINNACLE (CHU) Recall

Item Affected: SUSPENSION:FRONT:HUB

Date Announced: 12/23/2016

Description of Recall: 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.

Conequence: 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.

Conequence: 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.

Action Need To Fix It: 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.

Description of Recall: Mack Trucks, Inc. (Mack) is recalling certain model year 2016-2017 Titan vehicles manufactured from February 25, 2015, through February 12, 2016. The bolt connecting the upper steering shaft to the lower steering shaft may not properly secure the upper steering shaft, which can lead to separation of the steering shaft.

Conequence: Separation of the steering shaft will result in complete loss of steering which may lead to a vehicle crash.

Action Need To Fix It: Mack strongly recommends that the affected vehicles not be driven until the interim remedy is applied. An interim notice was sent to Mack owners on March 21, 2016, and an interim repair is available now. A second notice was mailed on May 12, 2016. The final remedy is now available.

2016 MACK LEU Recall

Item Affected: ENGINE AND ENGINE COOLING:ENGINE

Date Announced: 05/11/2015

Description of Recall: Mack Trucks, Inc. (Mack) is recalling certain model year 2011-2016 Mack MRU and LEU trucks manufactured June 25, 2010, to April 30, 2015, and 2015-2016 LR6 trucks manufactured from December 18, 2014 through March 6, 2015. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.

Conequence: If engine oil comes into contact with a hot surface, there could be an increased risk of a fire.

Action Need To Fix It: Cummins will notify owners on behalf of Mack, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Mack customer service at 1-800-528-6586 or Cummins Inc. at 1-800-343-7357. Mack's number for this recall is SC0391.

Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

2016 MACK LEU Recall

Item Affected: PARKING BRAKE:DRIVELINE:HYDRAULIC:ACTUATOR

Date Announced: 01/22/2015

Description of Recall: 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 the parking brake section of the Life Seal actuator.

Conequence: 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.

Action Need To Fix It: 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.

Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
