- 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.

Engine recalls for the 2004 Orion Vii
- 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.
- The problem
- Certain my 2000-2005 detroit diesel series 50g engines manufactured between october 2, 2002, and march 22, 2005, equipped on certain 2002-2004 orion v and 2002-2005 orion vii transit buses. Higher than expected temperatures will allow the low pressure natural gas regulator gasket to leak coolant and drip onto the terminals of the battery charging alternator.
- The risk
- This can result in a short in the electrical circuit and the potential for an engine compartment fire.
- The fix
- Detroit diesel will notify owners and repair the engines by replacing the low pressure regulator gasket with an improved gasket free of charge. The recall began on april 7, 2006. Owners may contact detroit diesel at 313-592-3708.
