NHTSA Recall 15V288000
Filed by Daimler Buses North America. Component: Engine And Engine Cooling. Reported 2015-05-15. An estimated 455 vehicles are affected. Recall repairs are free at any authorized dealer.
Defect
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.
Risk
If the engine oil comes into contact with hot surfaces, it can increase the risk of a vehicle fire.
What the manufacturer will do
Cummins will notify owners on behalf of DBNA, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact DBNA at 1-905-403-7807 or Cummins Inc. at 1-800-343-7357.
