2. 16V929000Received 23 Dec 2016. 200 units.

   Suspension / Front / Hub

   Defect, in the NHTSA record

   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.

11. 12V037000Received 1 Feb 2012. 2 units.

    Service Brakes, Air / Supply / Check Valve

    Defect, in the NHTSA record

    Mack is recalling certain model year 2012-2013 gu, manufactured from december 2, 2010, through january 18, 2012, and equipped with bendix atr-6 traction relay valves. In extremely cold conditions, these bendix relay valves may potentially develop internal leakage. Internal leakage can lead to air pressure being delivered to affected primary or secondary brake causing continuous brake application.

    Consequence, in the NHTSA record

    Inadvertent brake application can cause the brakes to overheat and lead to a fire. Inadvertent brake application can cause the wheels to lock-up leading the driver to lose control of the vehicle, increasing the risk of a crash.

    Remedy, in the NHTSA record

12. 11V295000Received 20 May 2011. 584 units.

    Power Train / Driveline

    Defect, in the NHTSA record

    Mack trucks is recalling certain model year 2012, chu, cxu, gu, mru, leu, and td trucks equipped with a meritor driveline. The tubing used to assemble the affected drivelines has a nonconforming seam weld with insufficient bonding of the material.

    Consequence, in the NHTSA record

    This can result in seam weld fracture when torque is applied. Once the tube seam weld is fractured, the driveline may become inoperable which may result in a disabled vehicle or debris from the driveline may fall on the roadway, both of which can increase the risk of a crash.

    Remedy, in the NHTSA record

    Dealers will replace the drivelines free of charge. The safety recall began on july 25, 2011. Owners may contact mack trucks at 1-800-528-6586.

    Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0353. Owner notification date in the NHTSA record: 25 Jul 2011.

13. 11V272000Received 3 May 2011. 1,524 units.

    Defect, in the NHTSA record

    Mack trucks is recalling certain model year 2011-2012 chu, cxu, gu, leu and mru trucks manufactured from october 15, 2010, through january 31, 2011, and equipped with gunite automatic slack adjusters. Due to an incomplete "knitting" of the iron at the time of casting, inadequate structural integrity of the slack adjuster housing can occur, which could cause the housing to break at the handle under normal operating loads.

    Consequence, in the NHTSA record

    Slack adjusters with this flow notch could crack under normal braking conditions causing loss of braking which could result in a vehicle crash.

    Remedy, in the NHTSA record

    Mack trucks will notify owners and dealers will replace the subject slack adjusters free of charge. The safety recall began on august 24, 2011. Owners may contact mack trucks at 1-800-528-6586.
