SUSPENSION:FRONT:HUB
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.
Risk: 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.

ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER
Mack Trucks, Inc. (Mack) is recalling certain model year 2010-2016 Granite (GU), LR, and TerraPro (LEU, MRU) trucks manufactured November 17, 2009 to October17, 2015. The affected trucks have engines with a turbocharger oil supply line that may contact or interfere with the turbocharger inlet elbow, clean air intake clamp, or the air fuel control tube, and result in an oil leak.
Risk: If the turbocharger oil supply line oil leaks in the proximity of the engine exhaust manifold there would be an increased risk of a fire.

ELECTRICAL SYSTEM
Mack Trucks, Inc. (Mack) notified the agency on February 20, 2014, that they are recalling certain model year 2010-2012 CHU, CXU, GU and TD vehicles manufactured from June 16, 2009, through July 8, 2011. While continuing to research the scope of the issue, Mack expanded the recall on November 18, 2014 to include certain model year 2008-2009 and 2013-2014 CHU, CXU, GU and TD vehicles manufactured from June 16, 2009, through July 8, 2011. Having completed its investigation, Mack once again expanded the recall during February 2015 to include an additional 53,780 vehicles from model years 2007 and 2015. The recall now covers model year 2007-2015 includes CHU, CXU, GU and TD vehicles produced October 13, 2006, through October 3, 2014. In the affected vehicles, the Electronic Power Distribution Module (EPDM) may be contaminated from water leaks in, and around, the windshield. If exposed to water leaks, contaminants such as road salts may deposit on the EPDM.
Risk: Deposits of contaminants may result in the circuits being bridged, creating a high resistance short, increasing the risk of a fire.

VISIBILITY:WINDSHIELD WIPER/WASHER:LINKAGES
MACK IS RECALLING CERTAIN MODEL YEAR 2012 CHU, CXU, AND GU VEHICLES, MANUFACTURED FROM OCTOBER 10, 2011, THROUGH NOVEMBER 17, 2011. HARDWARE USED TO SECURE THE WINDSHIELD WIPER LINKAGE TO THE WIPER MOTOR MAY NOT BE SUFFICIENTLY TORQUED, AND MAY CAUSE THE WINDSHIELD WIPER LINKAGE TO DETACH FROM THE WIPER MOTOR. AS A RESULT, THE WINDSHIELD WIPERS WILL NOT FUNCTION.
Risk: IF THIS OCCURS, UNDER CERTAIN DRIVING CONDITIONS THE DRIVER'S VISIBILITY WILL BE REDUCED, INCREASING THE RISK OF A CRASH.

SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE
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.
Risk: 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.

POWER TRAIN:DRIVELINE
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.
Risk: 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.

SERVICE BRAKES, AIR:SLACK ADJUSTERS:AUTOMATIC
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.
Risk: SLACK ADJUSTERS WITH THIS FLOW NOTCH COULD CRACK UNDER NORMAL BRAKING CONDITIONS CAUSING LOSS OF BRAKING WHICH COULD RESULT IN A VEHICLE CRASH.
