- Summary
- On certain buses equipped with compressed natural gas fuel containers, the thermal properties of the original exhaust blanket were insufficiently achieved with the component supplied. The performance of the exhaust temperature and the exhaust blanket were incorrectly evaluated for the supplied blanket.
- Consequence
- The exhaust blanket can be degraded and lose insulating value. Surrounding components can degrade in the engine compartment and can malfunction due to the effect on wires and hoses.
- Remedy
- Dealers will install a replacement exhaust blanket. The recall began July 17, 2005. Owners should contact orion at 905-403-7832
- Notes
- Customers can also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

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.
