- The problem
- 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.
- The risk
- If the engine oil comes into contact with hot surfaces, it can increase the risk of a vehicle fire.
- The fix
- 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.

A port authority owned 2006 orion vi diesel powered airport shuttle bus was destroyed by fire on 6/28/08 at about 12:00 a.M. Fortunately the bus was not carrying passengers at the time, as the fire spread quickly and destroyed the bus even though it was equipped with an on-board fire suppression system that discharged agent into the engine compartment. Following an investigation by a forensic engineer with extensive experience in diesel fires, it was determined that the probable cause of the fire was the wear and...
