2009 THOMAS BUILT BUSES SAF-T-LINER HDX

EQUIPMENT

Daimler Trucks North America LLC (DTNA) is recalling certain 2002-2017 Thomas Built Buses Saf-T-Liner C2, Saf-T-Liner HDX, FS65, and Minotour school buses, equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

EQUIPMENT ADAPTIVE/MOBILITY

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2006-2015 Thomas Built Buses FS-65, Saf-T-Liner C2, Saf-T-Liner EF, Saf-T-Liner EFX, Saf-T-Liner HDX, and Minotour DRW school buses manufactured January 3, 2006, to August 1, 2014, and equipped with certain Ricon model S2005, S2010, S5005, S5010, S5505, S5510 wheelchair lifts. The affected lifts are equipped with folding link arms that may have pivot holes that are too big, allowing the bearings to move out of position.

Risk: If the bearings move out of position, the stowed platform may have excessive movement resulting in failure of the platform mounting. This failure could cause the wheel chair lift platform to fall out of the vehicle when the doors are opened, increasing the risk of injury for the lift operator.

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2002-2004 Thomas Built Buses Saf-T-Liner ER, 2001-2005 Saf-T-Liner Conventional, 2002-2013 Saf-T-Liner MVP-EF, 2013 Saf-T-Liner EFX, 2001-2008 Saf-T-Liner FS65, 2005-2013 Saf-T-Liner C2, 2003-2013 Saf-T-Liner HDX, 2002-2003 Saf-T-Liner MVP-ER, 2002 Vista, and 2002-2003 TL-960 non-school buses. In the affected vehicles, the stem that connects the outside emergency door handle to the emergency door opening mechanism may corrode.

Risk: If the stem corrodes, the door handle could detach from the emergency door opening mechanism, delaying the opening of the door and the evacuation of the bus. In the event of an emergency, this may increase the risk of injury to the bus occupants.

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2008-2015 Thomas Built Buses Saf-T-Liner HDX school buses manufactured May 25, 2008, to December 18, 2014, and 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.

Daimler Trucks North America LLC (Daimler) is recalling certain model year 2009-2015 Thomas Built Saf-T-Liner HDX school buses manufactured February 25, 2008, through February 11, 2014, equipped with Cummins Westport Model ISL 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.
