Daimler Buses North America (DBNA) is recalling certain model year 2007-2012 Orion VII natural gas-powered transit buses manufactured January 1, 2007, to October 1, 2012. 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.
Daimler Buses North America (DBNA) is recalling certain model year 2007-2012 Orion VII transit buses manufactured January 2007 through October 2012 equipped with certain 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.
Daimler Buses North America Ltd. (DBNA) is recalling certain model year 2003-2008 Orion V and model year 2002-2010 VII buses equipped with Sure Power equalizers and DC-DC Converters.
