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

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM
Mack Trucks, Inc. (Mack) is recalling certain model year 2010-2015 LEU vehicles manufactured May 14, 2009, through February 14, 2014, and equipped with a Cummins ISL engine. In the affected vehicles, the exhaust pipe may disconnect from the muffler/catalyst.
Risk: If the exhaust pipe separates from the muffler on a twin-steer configured vehicle where the vehicle is operated from the right side, the operator may be exposed to carbon monoxide levels which may cause personal injury.

Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
Risk: The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.

ELECTRICAL SYSTEM
MACK TRUCKS IS RECALLING CERTAIN MODEL YEAR 2008-2012 MRU AND LEU HEAVY TRUCKS MANUFACTURED FROM JANUARY 3, 2007, THROUGH FEBRUARY 3, 2011. THE ELECTRICAL CIRCUITRY IN THESE VEHICLES MAY NOT PROVIDE ADEQUATE OVERCURRENT PROTECTION.
Risk: IN THE EVENT OF AN ELECTRICAL OVERAGE, THE FUSE THAT SHOULD PREVENT THE OVER CURRENT FROM REACHING THE MIRROR SWITCH CIRCUIT MAY FAIL, SUCH THAT THE MIRROR SWITCH CAN OVERHEAT. AN OVERHEATED SWITCH COULD CAUSE A VEHICLE FIRE.
2011 MACK LEU
1524 vehicles affected
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.
