Fatal crashes in the US
From 2020 to 2023, 3 2008 CHU vehicles were involved in crashes on US public roads in which someone died; 2 people died inside them, and 2 of the vehicles rolled over. This is a count, not a crash rate: it grows with the number of cars on the road.

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.
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.
ON CERTAIN TRUCKS, THE BOLTS THAT ATTACH THE STEERING GEAR TO THE FRAME MAY NOT HAVE BEEN TIGHTENED TO THE SPECIFIED TORQUE.
ON CERTAIN TRUCKS, THE DAYTIME RUNNING LIGHTS (DRL) MODULE MAY CONTAIN A SUSPECT METAL-OXIDE-SEMICONDUCTOR FIELD EFFECT TRANSISTOR (MOSFET) THAT COULD OVERHEAT.
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.
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.
ON CERTAIN TRUCKS, AN UNPROTECTED LEAD IN THE THERMOSWITCH OF THE HEATER MAY MAKE CONTACT WITH ANOTHER POST POSSIBLY CREATING A SHORT CIRCUIT, WHICH CAN RESULT IN CONTINUOUS OPERATION OF THE HEATING ELEMENT.
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.
