Defect:
Mack trucks is recalling certain model year 2011 chu and cxu, heavy trucks manufactured from july 13, 2010, through august 13, 2010, without rear mud flap hanger brackets. these vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 108, "lamps, reflective devices, and associated equipment." the rear conspicuity treatment typically found on the mud flap hanger brackets may not have been installed in the alternate positions as allowed in the regulation on vehicles manufactured without rear mud flap hanger brackets.
Consequence:
Lack of reflectors could lead to reduced visibility of the vehicle increasing the risk of a crash.
Correction:
Dealers will inspect and install conspicuity treatment as required free of charge. the safety recall began on february 2, 2011. owners may contact mack trucks at 1-800-866-1177.

Affected:
808
Defect:
Mack trucks is recalling certain model year 2008-2011 chu and cxu heavy trucks manufactured from january 2008 through july 2010. there may be an interference with the bolts used to secure the fifth wheel to the frame that can prevent the bolts from being torqued to specification.
Consequence:
The bolts may fail and could result in the fifth wheel coming loose causing the trailer to separate from the tractor increasing the risk of a crash.
Correction:
Dealers will inspect and replace the bolts as required free of charge. the safety recall began on may 30, 2011. owners may contact mack trucks at 1-800-866-1177.
Notes:

Mack trucks is recalling certain model year 2011-2012 chu, cxu, gu, leu and mru trucks manufactured from october 15, 2010, through january 31, 2011, and equipped with gunite automatic slack adjusters. due to an incomplete "knitting" of the iron at the time of casting, inadequate structural integrity of the slack adjuster housing can occur, which could cause the housing to break at the handle under normal operating loads.
Consequence:
Slack adjusters with this flow notch could crack under normal braking conditions causing loss of braking which could result in a vehicle crash.
Correction:
Mack trucks will notify owners and dealers will replace the subject slack adjusters free of charge. the safety recall began on august 24, 2011. owners may contact mack trucks at 1-800-528-6586.

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