Each recall: problem, risk and fix
Engine And Engine Cooling › Engine (15V275000, 2015-05-11)
Problem: 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.
Free fix: 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.

Risk: A failure of the hazard warning lights could reduce the trucks visibility, increasing the risk of a crash.
Free fix: Mack will notify owners, and dealers will replace the electronic flasher unit, free of charge. The recall will begin by mid-June 2014. Interim letters went out to owners on June 23, 2014.

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.
Free fix: Cummins and Cummins Westport will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on March 12, 2014.

Problem: 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.
Free fix: Mack will notify owners. The recall began on April 21, 2014. The recall is expected to begin in late April 2014. Owners may contact Mack Trucks at 1-336-393-2000. Mack's number for this recall is SC0376.

Problem: Mack is recalling certain model year 2010-2012 leu and model year 2011-2012 mru vehicles, manufactured from may 14, 2009, through october 31, 2011, and built to operate on compressed natural gas. On these vehicles the alternator ground cable runs directly to the starter, which defeats the circuit protection.
Risk: In the event of an electrical short, a vehicle fire may result.
Free fix: Mack will notify owners, and dealers will relocate the alternator ground cable to the engine ground stud. This service will be performed free of charge. The recall began on april 19, 2012. Owners may contact mack trucks at 1-800-866-1177.

Risk: Complete fractures can cause the driver to lose control of the vehicle, increasing the risk of a crash.
Free fix: Mack will notify owners, and replace the axle beams on affected vehicles when sufficient quantities are available. As an interim measure, a mag particle inspection will be provided to mitigate risk and identify vehicles with cracked axle beams. This service will be performed free of charge. The safety recall began march 30, 2012. Owners may contact mack trucks at 1-800-866-1177.

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.
Free fix: 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.

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.
Free fix: Dealers will install a relay harness to prevent the mirror switch from overheating. They will also inspect the mirror switch and if signs of overheating are shown, replace that switch. All inspections and repairs will be performed free of charge. The safety recall began on june 30, 2011. Owners may contact mack trucks at 1-800-866-1177.
