   Exterior Lighting / Turn Signal / Flasher Unit

   Defect, in the NHTSA record

   Report filed by Mack Trucks, Inc.. Manufacturer campaign number SC0379. Owner notification date in the NHTSA record: 25 Jul 2014.

2. 14V078000Received 21 Feb 2014. 70,208 units.

   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. 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, 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. Owners may contact Mack Trucks at 1-336-393-2000. Mack's number for this recall is SC0375.

   Defect, in the NHTSA record

   Mack is recalling certain model year 2008 through 2011 gu and mru model vehicles manufactured with a front tow glad hand option. The actuation and release timing of the vehicles exceeds the limit which fails to conform to the requirements of federal motor vehicle safety standard no. 121, "air brake systems."

5. 07V478000Received 11 Oct 2007. 61 units.

   Exterior Lighting

   On certain trucks, the daytime running lights (drl) module may contain a suspect metal-oxide-semiconductor field effect transistor (mosfet) that could overheat.

   Consequence, in the NHTSA record

   If the transistor overheats, it could possibly result in a vehicle fire.

   Remedy, in the NHTSA record

   Dealers will replace the suspect drl module free of charge. The recall began on october 31, 2007. Owners may contact mack trucks at 1-800-528-6586.

6. 07V361000Received 15 Aug 2007. 21,847 units.

   Service Brakes, Air / Supply / Check Valve

   Defect, in the NHTSA record

   On certain trucks equipped with parker single check valves (scv) provided by bendix. The defect exists in the parker scv that connects with the supply port of the sr-7 spring brake modulating valve. After prolonged use of the parker scv, the valve body retainer may become excessively worn and eventually break apart. Pieces of the parker scv can become lodged inside the sr-7 spring brake modulating valve, potentially causing either leakage out of the sr-7 valve or preventing air from properly exhausting from the sr-7 valve.

   Consequence, in the NHTSA record

   This condition can cause a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button. These conditions can occur without warning, leading to unintended vehicle rollaway, brake drag, or in the case of loss of primary circuit, inability to modulate the spring brakes.

   Remedy, in the NHTSA record

   Mack is working with bendix to replace the parker single check valve. The recall began on january 9, 2008. Owners may contact bendix at 1-440-329-9000 or mack at 1-800-528-6586.

   Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0334. Owner notification date in the NHTSA record: 9 Jan 2008.

7. 07V360000Received 15 Aug 2007. 18,805 units.

   Parking Brake

   Defect, in the NHTSA record

   On certain trucks equipped with bendix sr-7 spring brake modulating valves, the internal rubber check valve may leak causing a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button.

   Consequence, in the NHTSA record

   This could delay or failure in applying the parking brakes which could result in a vehicle roll away, increasing the risk of a crash.

   Remedy, in the NHTSA record

   Mack is working with bendix to repair these vehicles (please see 07e037). Bendix will install a check valve repair kit for the affected sr-7 spring brake modulating valve free of charge. The recall began on january 10, 2008. Owners may contact bendix at 1-440-329-9000 or mack at 1-800-528-6586.

   Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0335. Owner notification date in the NHTSA record: 10 Jan 2008.

8. 07V322000Received 24 Jul 2007. 1,072 units.

   Steering

   Defect, in the NHTSA record

   On certain trucks, the nut used to retain the steering shaft may or may not be a lock nut that has the locking feature. A lock nut is required to provide additional resistance to ensure that the nut does not come loose.

   Consequence, in the NHTSA record

   If the nut were to come loose and be left untreated, the steering shaft could potentially separate increasing the risk of a crash.

   Remedy, in the NHTSA record

   Dealers will replace the steering shaft pinch bolts and locknuts free of charge. The recall began on august 24, 2007. Owners may contact mack trucks at 1-800-528-6586.

   Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0326. Owner notification date in the NHTSA record: 24 Aug 2007.

9. 07V098000Received 14 Mar 2007. 3,587 units.

   Service Brakes, Hydraulic / Pedals and Linkages

   Defect, in the NHTSA record

   On certain trucks, the cotter pin that retains the brake pedal clevis pin may not have been installed. The clevis pin connects the brake pedal to the brake foot valve.

   Consequence, in the NHTSA record

   If the pin were to come loose, the driver would not be able to apply the service brake, which could result in a crash.

   Remedy, in the NHTSA record

   Dealers will inspect to see if the cotter pin is missing. If the pin is missing, the cotter pin will be installed. Owners are being advised not the drive the vehicle until the pin has been installed. The recall began on march 26, 2007. Owner may contact mack truck at 1-800-528-6586.

   Report filed by MACK TRUCKS, INC. Manufacturer campaign number SC0321. Owner notification date in the NHTSA record: 15 Mar 2007.
