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

Vehicles covered
As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.
Has your Orion been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Orion dealer can also check your VIN. Recall repairs are free.
