Recalls
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."
Ferrara Fire Apparatus, Inc. (Ferrara) is recalling certain 2015-2016 Inferno and International 4400, 2013-2016 Igniter, 2014-2017 Cinder and Freightliner M2 106, 2013-2014 Ember and 2013-2017 Kenworth T370 fire-fighting vehicles, equipped with Hale pressure relief valves in the water pumps used for fire fighting. Rings securing the valves may corrode over time after exposure to water, causing the ring to fail and the pressure relief valve to open, reducing the water pressure available for fire fighting.
E-One Incorporated (E-One) is recalling certain 2013-2017 E-One Cyclone II, Quest, Typhoon, 2016 Freightliner M2 112, 2013-2015 International 7400, 2014-2017 International 4400, Freightliner M2 106, 2016-2017 Kenworth T370, and 2015 Kenworth T800 vehicles equipped with Hale pressure relief valves in the water pumps used for fire fighting. Rings securing the valves may corrode over time after exposure to water, causing the ring to fail and the pressure relief valve to open, reducing the water pressure available for fire fighting.
Fontaine Modification is recalling certain model year 2014-2016 Freightliner M2 vehicles converted to be equipped with dual steering wheels by Fontaine Modification between March 13, 2014 and September 1, 2015. In the affected vehicles, a locating pin in the dual steering linkage may break or fall out resulting in the momentary loss of steering or steering lock up.
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.
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."
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.
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.
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.
Daimler Trucks North America LLC (DTNA) is recalling certain model year 2014 Freightliner 108SD, 114SD, 122SD, Coronado, Argosy, Cascadia, Columbia, and M2 Business Class, and Western Star 4700, and 4900 vehicles manufactured August 5, 2013, through November 15, 2013, and equipped with IMMI-brand L9 seat belt buckles. When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 209, "Seat Belt Assemblies."
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.
