SERVICE BRAKES, AIR:SUPPLY:RESERVOIR/TANK

Daimler Trucks North America LLC (DTNA) is recalling certain 2004-2019 Freightliner 108SD, 114SD, 122SD, Cascadia, Columbia, Classic, FL80, FLD 120SD, Business Class M2, Western Star 4700, 4900, 6900, Sterling Acterra, L7500, LT7500, L8500, LT8500, L9500, and LT9500 vehicles. The vehicles may have an insufficient service brake air reservoir capacity. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

Risk: An insufficient air reservoir volume may reduce brake effectiveness, increasing the risk of crash.

EQUIPMENT ADAPTIVE/MOBILITY

Farber Specialty Vehicles (Farber) is recalling various specialty vehicles modified by Farber and equipped with model S2005, S2010, S5005, S5010, S5505, and S5510 wheelchair lifts manufactured by Ricon Corporation. The platform side plate of the affected wheelchair lifts may crack.

Risk: If the platform side plates crack, the lift platform can separate from the lift and come to rest against the vehicle's lift door. When the doors are opened, the platform may fall out, increasing the risk of injury to the lift operator.

ENGINE AND ENGINE COOLING:ENGINE

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2007-2016 Freightliner 114SD and M2 Business Class trucks, 2008-2009 Sterling LT8500 trucks and Thomas Built Bus Saf-T-Liner HDX transit buses equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.

Risk: If engine oil comes into contact with a hot surface, there is an increased risk of a fire.

SERVICE BRAKES, AIR

Fontaine Modification (Fontaine) is recalling certain model year 2006-2015 Freightliner M2 trucks manufactured January 2, 2006, to January 23, 2015 and modified by Fontaine to have dual steering. Brake lights of the affected vehicles will not illuminate if the primary brake air supply is depleted below 6 psi. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

Risk: If the primary brake air system fails causing the truck to rely on the secondary brake air system, the brakes lights may not illuminate when the brakes are applied, increasing the risk of a crash.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

Daimler Trucks of North America LLC (DTNA) is recalling certain model year 2011-2015 Freightliner Cascadia and M2 trucks manufactured June 2, 2011 to October 23, 2014. The vehicles are not in compliance with the requirements of the Federal Motor Vehicle Safety Standards No. 303, "Fuel System Integrity Of Compressed Natural Gas Vehicles." Specifically, the tail pipe on these vehicles terminates under the compressed natural gas (CNG) tank and can overheat the fuel system.

Risk: Due to the area of its placement, the exhaust system forces heat around, and may overheat, the fuel system components, increasing the risk of a vehicle fire.

ENGINE AND ENGINE COOLING:ENGINE

Daimler Trucks North America LLC (Daimler) is recalling certain model year 2008-2015 Freightliner 114SD, Cascadia, M2 Business Class, Sterling LT8500, and Thomas Built Buses Saf-T-Liner HDX vehicles manufactured February 19, 2008, through February 11, 2014, and equipped with Cummins Westport Model ISL G and Cummins Westport Model ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.

Risk: The sensor malfunction could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.

SERVICE BRAKES, AIR:SLACK ADJUSTERS:AUTOMATIC

DTNA IS RECALLING CERTAIN MODEL YEAR 2011 FREIGHTLINER CASCADIA, COLUMBIA GLIDER KIT, CORONADO, M2, AND WESTERN STAR4900 HEAVY TRUCKS MANUFACTURED FROM OCTOBER 16, 2010, THROUGH MARCH 9, 2011, EQUIPPED WITH GUNITE AUTOMATIC SLACK ADJUSTERS MANUFACTURED FROM OCTOBER 15, 2010, THROUGH JANUARY 31, 2011. 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.

Risk: IF THE SLACK ADJUSTER HOUSING WERE TO BREAK, THE WHEEL BRAKE TO WHICH THE SLACK ADJUSTER IS ATTACHED WOULD NO LONGER FUNCTION, CAUSING THE VEHICLE TO HAVE REDUCED BRAKING CAPACITY AND, IF MOUNTED ON THE STEER AXLE, THE VEHICLE COULD PULL TO ONE SIDE, POSSIBLY RESULTING IN A CRASH.

POWER TRAIN:DRIVELINE

THE TUBING USED TO ASSEMBLE THE AFFECTED DRIVELINES HAS A NONCONFORMING SEAM WELD WITH INSUFFICIENT BONDING OF THE MATERIAL.

Risk: A TUBE SEAM WELD THAT IS NOT PROPERLY BONDED CAN RESULT IN THE DRIVELINE ASSEMBLY FRACTURING ALONG THE LENGTH OF THE TUBE SEAM WELD. THE FRACTURED TUBE CAN TWIST OR SEVER. THIS COULD RESULT IN ADDITIONAL DAMAGE TO THE DRIVELINE, THE VEHICLE TO WHICH IT IS ATTACHED AND ANY ADDITIONAL NEARBY COMPONENTS. THIS MAY INCREASE THE RISK OF A CRASH.

ELECTRONIC STABILITY CONTROL (ESC)

DAIMLER TRUCKS IS RECALLING CERTAIN MODEL YEAR 2006-2012 FREIGHTLINER BUSINESS CLASS M2, CASCADIA, CENTURY, COLUMBIA, CORONADO AND STERLING A-LINE VEHICLES BUILT WITH MERITOR WABCO ELECTRONIC STABILITY CONTROL (ESC) SYSTEM MANUFACTURED FROM SEPTEMBER 15, 2005 THROUGH SEPTEMBER 1, 2011. UNDER CERTAIN ROAD AND DRIVING CONDITIONS, VEHICLE BODY ROLL AND ROAD INCLINATION CHARACTERISTICS MAY ADVERSELY AFFECT THE SLIP ANGLE CALCULATION OF THE ELECTRONIC STABILITY CONTROL (ESC) SYSTEM. THIS MIGHT CAUSE THE ESC TO PERCEIVE AN OVER STEERING SITUATION AND THEREFORE APPLY THE OUTER WHEEL BRAKE ON THE FRONT AXLE UNTIL THE VEHICLE IS PERCEIVED TO BE STABLE.

Risk: IF THE DRIVER IS SLOW TO REACT DURING THIS ESC INTERVENTION, THE VEHICLE MAY DEVIATE FROM THE INTENDED LINE OF TRAVEL INCREASING THE RISK OF A CRASH.
