9 recalls found. |
DEFECT #1 - SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE
Posted on: 2007-08-16
Description
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
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.
Corrective Action
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.

DEFECT #9 - ELECTRICAL SYSTEM
Posted on: 2014-02-28
Description
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.

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