Mack Trucks Inc. (Mack) is recalling certain model year 2010-2015 CXU trucks manufactured November 20, 2009, through January 27, 2014, and equipped with dual vertical exhaust pipes. The white conspicuity reflectors on the rear of the cab could be blocked by the exhaust pipes. As such, these vehicles do not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence & remedy
Consequence: A blocked reflector makes the truck-tractor less visible when operating the vehicle without a trailer in the dark, increasing the risk of a crash.
Remedy: Mack will notify owners, and dealers will inspect the trucks and if the reflectors are blocked, they will add two vertical white reflectors to the rear glass , free of charge. The recall began on May 30, 2014. Owners may contact Mack Customer Service at 1-336-393-2000. Mack's number for this recall is SC0378.
Mack Trucks Inc. (Mack) is recalling certain model year 2010-2014 CHU, CXU, and MRU, 2007 CT and CV, 2008-2014 GU, and 2011-2014 LEU, and TD trucks manufactured February 28, 2006, through November 8, 2013, and equipped Hamsar Electronic Flasher. The hazard warning lights may fail.
Consequence & remedy
Consequence: A failure of the hazard warning lights could reduce the trucks visibility, increasing the risk of a crash.
Remedy: 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. The recall began on July 25, 2014. Owners may contact Mack customer service at 1-866-298-6586. Mack's number for this recall is SC0379.
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.
Consequence & remedy
Consequence: Deposits of contaminants may result in the circuits being bridged, creating a high resistance short, increasing the risk of a fire.
Remedy: Mack has notified owners, and dealers will inspect the EPDM. If contamination has occurred, dealers will replace the EPDM and address the leak, free of charge. Owners of model year 2010-2012 CHU, CXU, GU and TD vehicles were initially notified April 24, 2014. Owners affected by the recall expansions were notified in February 2015. Owners may contact Mack Trucks at 1-336-393-2000. Mack's number for this recall is SC0375.
Mack is recalling certain model year 2007-2010 CHU and CXU vehicles, manufactured from October 13, 2006, through December 23, 2009 and equipped with daytime running lights and fog lights. A short in the fog light circuit may cause the low beam headlight circuit to cut out.
Consequence & remedy
Consequence: If the low beam headlights go out, the driver may lose visibility, increasing the risk of a crash.
Remedy: Mack will notify owners, and install an additional wiring harness on the affected vehicles, free of charge. The safety recall began on November 14, 2012. Owners may contact Mack Trucks at 1-800-866-1177.

On October 3rd 2010 the Office of Defects Investigation (ODI) received two complaints on 2009 - 2010 Mack CXU612 and CXU trucks for failing bolts that clamp the 5th wheel to the frame of the truck. On January 19, 2011 ODI opened this Preliminary Evaluation.During the course of the investigation ODI took possession of fasteners from the field.These fasteners, taken off subject complaint vehicles, exhibited 'hourglass like stretching' indicating plastic deformation.This same source supplied ODI with new fasteners (for the subject vehicle) that were recently purchased and never used.The bolts supplied by the manufacturer are M16 x 2 Class 10.9 bolts.Per SAE J1199, these bolts should have a proof load 130 kN (~29,000 lbf) and tensile strength of 163 kN (~36,600 lbf).These bolts are not designed to be torque to yield.ODI took possession of these field samples and sent them to (VRTC) Vehicle Research and Testing Center for testing.Some of the new and used fasteners from the field were tested to the SAE J1199 standard and all passed.Other tests at VRTC indicated that the stretched bolts were likely the result of over torque during installation or maintenance.VRTC tested other methods to pre-tension the bolts and found that load indicating washers and turn-of-the-nut method both gave better clamping load control than a torque wrench.In February 2011 Mack started to perform field inspections associated with this investigation in an attempt to understand the cause of the bolt failures.During these inspections, Mack discovered that there was an interference with the bolts used to secure the fifth wheel to the frame.This interference can prevent the bolts from being torqued to specification.If this occurs, the bolt(s) may fail and in extreme cases may result in the fifth wheel coming loose causing the trainer to separate from the tractor.Mack has issued a voluntary Safety Recall 11V-209 for (failure of fifth wheel mounting bolts). However, claims in the field suggest the manufactured supplied fasteners are inferior and stretch regardless of interference.ODI will continue to monitor this issue and follow the completion progress.If failures continue, ODI may open another investigation to investigate future failures.Mack Truck's recall action resolves the issues raised by this investigation and, therefore, this investigation is closed.
