- 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.

Engine recalls for the 2007 Orion Vii
- The problem
- 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.
- The risk
- The improper operation of the sensor 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.
- The fix
- Cummins Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Owners may contact DBNA at 1-905-403-7807 or Cummins Inc. at 1-800-343-7357. Cummins' number for this recall is C1462 (for ISL G engines) or C1461 (for ISX12 G) engines.
- The problem
- Daimler buses is recalling 175 my 2004-2008 orion v and vii buses equipped with a cummins isl diesel engines. Due to various alternator cable routing configurations, it may be possible for the cable to rub on engine components.
- The risk
- When the cable rubbing is not detected during regular maintenance inspections, the insulation can rub to expose the electrified cable. Arcing can cause a fire to occur.
- The fix
- Daimler buses will reroute the alternator cable to ensure that the cable does not contact engine components. The recall is expected to begin on or before january 2009. Owners may contact daimler buses at 1-800-716-7466.
- The problem
- On certain transit buses equipped with cummins engines configured with diesel particulate filters (dpf) and ultra compact modules (ucm), the ucm may fail. The ucm is located in a wiring harness inside the engine compartment on the curb side.
- The risk
- The engine may stall and the ucm may fail causing a fire.
- The fix
- Owners will be provided with instructions and parts to replace the 5 amp circuit breaker with a 2 amp fuse to mitigate the failure of the ucm from subsequently causing a fire. The recall began on january 25, 2008. Owners may contact dcbusna/orion bus at 905-403-7832.
- The problem
- On certain transit buses built with cummins isl engines, the exhaust elbow was incorrectly assembled and welded during production. The upper flange has a butt type weld instead of a fillet type weld.
- The risk
- An exhaust system that is not maintained to ensure that there are no leaking sections can cause heat damage to surrounding components increasing the risk of a fire.
- The fix
- Owners will be reimbursed for the replacement of the exhaust elbow. The recall began during september 2007. Owners may contact orion at 1-800-716-7466.
