07/01/2007 - 07/18/2007
Affected:
61
Defect:
On certain trucks, the daytime running lights (drl) module may contain a suspect metal-oxide-semiconductor field effect transistor (mosfet) that could overheat.
Consequence:
If the transistor overheats, it could possibly result in a vehicle fire.
Correction:
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.
Notes:

Component:
Service brakes, air
Manufactured:
10/21/2007 - 06/29/2010
Affected:
369
Defect:
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."
Consequence:
If the brakes do not perform as they should, a vehicle crash could occur.
Correction:
Mack will notify owners and repair the vehicle free of charge. the safety recall began on february 1, 2011. owners may contact mack at 1-877-800-4945.
Notes:
Mack's recall campaign number is sc0345.owners may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to <a href=http://www.safercar.gov>http://www.safercar.gov</a> .

Defect:
Mack trucks is recalling certain model year 2008-2012 mru and leu heavy trucks manufactured from january 3, 2007, through february 3, 2011. the electrical circuitry in these vehicles may not provide adequate overcurrent protection.
Consequence:
In the event of an electrical overage, the fuse that should prevent the over current from reaching the mirror switch circuit may fail, such that the mirror switch can overheat. an overheated switch could cause a vehicle fire.
Correction:
Dealers will install a relay harness to prevent the mirror switch from overheating. they will also inspect the mirror switch and if signs of overheating are shown, replace that switch. all inspections and repairs will be performed free of charge. the safety recall began on june 30, 2011. owners may contact mack trucks at 1-800-866-1177.
Notes:
Mack trucks safety recall no. sc0349/sc0350.owners may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to <a href=http://www.safercar.gov>http://www.safercar.gov</a> .

Mack trucks is recalling certain model year 2008-2009 gu, leu, and mru trucks, manufactured from december 12, 2007, through may 8, 2008 and equipped with a certain focal mounted retarder control box. the control box may lose its electrical ground.
Consequence:
If the control box loses ground, it may have localized overheating. this could lead to a vehicle fire.
Correction:
All affected vehicles were sold to one customer that has already been notified. an official owner notification letter will be mailed to the one customer in early november 2012. mack will replace the suspect control box on the affected vehicles, free of charge. owners may contact mack trucks at 1-800-866-1177.
Notes:
Mack's recall number is sc0366.customers may contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty: 1-800-424-9153); or go to http://www.safercar.gov.
