Defect description

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.

Safety risk

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

Manufacturer remedy

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.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
