   Electrical System

   Defect, in the NHTSA record

   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.

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, in the NHTSA record

   Deposits of contaminants may result in the circuits being bridged, creating a high resistance short, increasing the risk of a fire.

   Remedy, in the NHTSA record

   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.

6. 08V331000Received 23 Jul 2008. 265 units.

   Exterior Lighting / Headlights

   Defect, in the NHTSA record

   Mack is recalling certain my 2009 trucks equipped with hella headlamps for failing to comply with the photometric output requirements of federal motor vehicle safety standard no. 108, 'lamps, reflective devices, and associated equipment." the headlamp's bulb shield may not have been completely seated into the headlamp's reflector.

   Consequence, in the NHTSA record

   This standard specifies requirements for required original and replacement lamps, reflective devices, and associated equipment and their installation. The purpose is to reduce traffic crashes, deaths and injuries resulting from crashes by providing adequate illumination of the roadway, and enhancing the conspicuity of motor vehicles on the public roads so that their presence is perceived and their signals understood, both in daylight and in darkness or other conditions of reduced visibility.

   Remedy, in the NHTSA record

   Dealers will inspect the headlamps for the suspect date codes and replace as required free of charge. The recall began on september 8, 2008. Owners may contact mack trucks at 1-800-528-6586.

   Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0340. Owner notification date in the NHTSA record: 8 Sep 2008.

7. 08V177000Received 17 Apr 2008. 66 units.

   Parking Brake / Conventional / Air

   Defect, in the NHTSA record

   Mack is recalling 66 my 2009 gu trucks equipped with bendix mv-3 dash control valves. The molded valve body has an incorrect core pin in the injection mold causing the valve body to be oversized in the double check valve area. This condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.

   Consequence, in the NHTSA record

   If the double check valve becomes lodged, in the event of a primary reservoir failure, air pressure can leak past the lodged double check valve thereby depleting the secondary reservoir, causing reduced ability for modulating the service emergency brakes increasing the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will inspect the mv-3 dash valve for the production date code. Valves in the affected production lots will be replaced free of charge. The recall began on may 9, 2008. Owners may contact mack trucks at 1-800-528-6586.

   Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0339. Owner notification date in the NHTSA record: 9 May 2008.
