- On certain transit buses with cummins ISB02 engines, the hydraulic line coming off of the power steering pump is rubbing on top of the air governor.

Has your Optima 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 Optima dealer can also check your VIN. Recall repairs are free.
