What NHTSA recorded
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.
Possible 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.
