2013 FREIGHTLINER M2

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.

PARKING BRAKE:CONVENTIONAL:AIR

Daimler Trucks North America LLC (DTNA) is recalling certain 2013-2015 Freightliner M2 trucks manufactured December 10, 2012, to October 28, 2014, and equipped with the auto-apply brake feature. In the affected vehicles, the parking brake may apply unintentionally.

Risk: If the parking brake applies without warning while driving and without activating the brake lights, there is an increased 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.

FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2013 Freightliner Business Class M2 vehicles manufactured May 29, 2012, to June 11, 2012, and equipped with certain compressed natural gas (CNG) fuel tank systems manufactured by Agility Fuel Systems. In the affected fuel systems, due to a separation of the valve seat from the valve stem, the manual tank shutoff valve can get internally stuck in the closed position while being opened, although the knob may indicate that the valve is open.

Risk: If the valve is stuck closed, the flow of fuel would be blocked from the fuel container to the engine. Such a condition poses a safety risk to service personnel as there is no safe way to depressurize the fuel system and service the subject valve when it is stuck in the closed position, increasing the risk of injury to the service personnel. There may also be a small fuel leak through the valve stem when the valve seat becomes detached, increasing the risk of fire. The affected fuel container may also become over-pressurized if the stuck valve goes undetected for a period of time, or is not repaired in a timely manner, and the ambient temperature increases significantly.
