Defect: Mack is recalling certain model year 2007-2010 CHU and CXU vehicles, manufactured from October 13, 2006, through December 23, 2009 and equipped with daytime running lights and fog lights. A short in the fog light circuit may cause the low beam headlight circuit to cut out.
Risk: If the low beam headlights go out, the driver may lose visibility, increasing the risk of a crash.
Fix: Mack will notify owners, and install an additional wiring harness on the affected vehicles, free of charge. The safety recall began on November 14, 2012. Owners may contact Mack Trucks at 1-800-866-1177.
