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.
