EXTERIOR LIGHTING

Daimler Trucks North America LLC (DTNA) is recalling certain 2006-2020 Freightliner Columbia, 2006-2021 Freightliner Business Class M2, 2007-2020 Freightliner Coronado, 2014-2021 Freightliner 122 SD, 2007 Sterling A 9500, 2006 Freightliner Argosy, 2006-2007 Sterling AT9500, 2008-2021 Freightliner Cascadia, 2006-2008 Freightliner Classic, 2006-2011 Freightliner Century Class, 2006-2010 Freightliner FLD, and 2017 Western Star 5700 vehicles. The rear reflective tape may be partially covered by the mudflap hanger bracket, which may reduce the vehicle's visibility to other drivers on the road. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: The vehicle's rearward visibility may be reduced, increasing the risk of a crash.

STEERING:LINKAGES:TIE ROD ASSEMBLY

Daimler Trucks North America, LLC (DTNA) is recalling certain 2012-2015 Freightliner Cascadia, Coronado, Business Class M2, 114SD, and Western Star 4900 trucks. In certain front axle, brake lining, and brake spider combinations, braking may cause high vibrations, resulting in early failure of the tie-rod tube.

Risk: A tie-rod failure would cause a disconnect between the front wheels, resulting in a loss of steering ability, thereby increasing the risk of a crash.

SERVICE BRAKES, AIR:DISC:CALIPER

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2010-2017 Freightliner M2 Business Class, 108SD, 114SD, and Columbia trucks manufactured from January 6, 2010, through February 29, 2016, equipped with certain Bendix rear disk brakes and spring suspensions. The rear disk brake caliper may have been installed incorrectly, thus allowing the caliper to contact the suspension.

Risk: Caliper contact with the spring suspension may reduce the braking effectiveness, increasing the risk of a crash.

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2011-2014 Cascadia, Business Class M2, Coronado, and Columbia Glider vehicles manufactured April 5, 2010, to June 15, 2013. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.

Risk: If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.

POWER TRAIN:AUTOMATIC TRANSMISSION

Daimler Trucks North America (DTNA) is recalling certain model year 2009-2014 model year Freightliner Business Class M2 and Freightliner Custom Chassis MT45 and MT55 chassis manufactured August 27, 2008, through December 10, 2013 and equipped with Eaton hybrid automated transmissions. The software controlling the affected transmissions may improperly raise the vehicle's engine speed during downshifts without the driver's input.

Risk: The increase in engine speed may result in unintended acceleration, increasing the risk of a crash.

ELECTRICAL SYSTEM

Daimler Trucks North America (DTNA) is recalling certain model year 2012-2013 Business Class M2, 108SD, 114SD vehicle chassis, manufactured from December 3, 2011, through October 12, 2012 and equipped with a SmartPlex switch hub module. Residue left over in the manufacturing process of the switch hub module may lead to intermittent shorts and energizing of certain switch hub module outputs.

Risk: If the module is energized, the module may inadvertently activate body equipment or features, increasing the risk of injury to the vehicle operator or increasing the risk of a crash.

EQUIPMENT

Daimler Trucks North America (DTNA) is recalling certain model year 2009-2012 Freightliner, Sterling, and Western Star vehicles manufactured from July 7, 2008, through December 15, 2011, and equipped with perpendicular air tank mounting brackets. The air tank mounting brackets may develop cracks which can lead to the air tank brackets separating from the frame rail. The air tanks may also separate from the vehicle.

Risk: Air tanks that become separated from a moving vehicle may create a road debris hazard, increasing the risk of a crash.

ENGINE AND ENGINE COOLING:ENGINE:DIESEL

DAIMLER TRUCKS (DTNA) IS RECALLING CERTAIN MODEL YEAR 2006-2013 FREIGHTLINER, STERLING, AND WESTERN STAR VEHICLES, EQUIPPED WITH DETROIT DIESEL EPA07 AND EPA10, DD13 AND DD15/16 ENGINES, MANUFACTURED FROM JANUARY 20, 2006, THROUGH FEBRUARY 20, 2012. THE PUMP TO RAIL HIGH PRESSURE FUEL LINE SUPPORT SYSTEM USED ON THESE ENGINES IS SENSITIVE TO ASSEMBLY TORQUE AND MAY BE DAMAGED DURING SERVICE WORK. AS A RESULT OF OTHER REPAIRS, THE LINE SUPPORTS MAY LOOSEN, POTENTIALLY LEADING TO FUEL LINE CRACKING AND A FUEL LEAK.

Risk: A FUEL LEAK COULD CREATE A ROAD HAZARD, INCREASING THE RISK OF A CRASH. ALSO A FUEL LEAK IN THE PRESENCE OF AN IGNITION SOURCE CAN RESULT IN A FIRE.

SERVICE BRAKES, AIR:SUPPLY:QUICK RELEASE VALVE

DAIMLER TRUCKS (DTNA) IS RECALLING CERTAIN MODEL YEAR 2012-2013 FREIGHTLINER 108SD, BUSINESS CLASS M2, CASCADIA, CORONADO VEHICLES, EQUIPPED WITH A HALDEX QUICK RELEASE VALVE, AND MANUFACTURED FROM FEBRUARY 3, 2012, THROUGH MARCH 2, 2012. THE QUICK RELEASE VALVE COVER MAY NOT BE CORRECTLY MANUFACTURED, ALLOWING THE COVER TO BECOME SEPARATED FROM THE VALVE BODY. IF THE COVER SEPARATES FROM THE VALVE BODY, THE FRONT BRAKES MAY NOT FUNCTION.

Risk: IF THIS CONDITION OCCURS, INCREASED VEHICLE STOPPING DISTANCE MAY RESULT, INCREASING THE RISK OF A CRASH.

STEERING:COLUMN

DAIMLER TRUCKS (DTNA) IS RECALLING ONE 2012 CASCADIA AND CERTAIN MODEL YEAR 2012 AND 2013 FREIGHTLINER BUSINESS CLASS M2 VEHICLES, AND MODEL YEAR 2013 108SD AND 114SD VEHICLES MANUFACTURED FROM JANUARY 20, 2012, THROUGH FEBRUARY 17, 2012. CERTAIN PROPERTY CLASS 04 (PC04) STEERING WHEEL NUTS WITH INCOMPLETELY FORMED THREADS WERE SUPPLIED TO DTNA IN LIEU OF THE SPECIFIED PROPERTY CLASS 05 NUTS. THE STEERING WHEEL NUTS SUPPLIED MAY NOT PROVIDE THE CLAMP LOAD REQUIRED TO FULLY SEAT THE STEERING WHEEL ON THE STEERING SHAFT WHEN TIGHTENED TO THE SPECIFIED TORQUE.

Risk: A STEERING WHEEL THAT IS NOT FULLY SEATED ON THE STEERING SHAFT MAY WOBBLE AND MAKE IT DIFFICULT TO CONTROL THE VEHICLE, INCREASING THE RISK OF A CRASH.

ENGINE AND ENGINE COOLING

DAIMLER TRUCKS IS RECALLING CERTAIN MODEL YEAR 2011- 2012 BUSINESS CLASS M2 AND CORONADO TRUCKS MANUFACTURED FROM SEPTEMBER 1, 2010, THROUGH DECEMBER 31, 2010, EQUIPPED WITH A CUMMINS ISX OR ISL DIESEL ENGINE. THE V-BAND CLAMP ASSEMBLY, PART NUMBERS Q187684, Q187685, AND Q187686, USED TO CONNECT THE INLET AND OUTLET CONE SECTIONS TO THE DIESEL OXIDATION CATALYST (DOC)/DIESEL PARTICULATE FILTER (DPF) INCLUDE A T-BOLT WHICH CAN FRACTURE AND FAIL WHEN SUBJECTED TO STRESS OR LOAD. A FRACTURE OR FAILURE OF THE T-BOLT MAY CAUSE THE CLAMP TO LOOSEN AND THE INLET OR OUTLET SECTIONS ATTACHED TO THE DOC/DPF HOUSING TO DISCONNECT.

Risk: IF THE INLET OR OUTLET SECTIONS DISCONNECT, HOT EXHAUST GASES CAN VENT PRIOR TO EXITING THE TAILPIPE, CREATING THE RISK OF COMBUSTION AND A FIRE. IF BOTH CLAMPS FAIL, THERE IS A RISK IN SOME APPLICATIONS THAT THE DOC/DPF HOUSING MAY DETACH COMPLETELY, CREATING A ROAD HAZARD.
