Common repairs in this area (not a diagnosis)

These are repair jobs that sit in the areas owners report most. A complaint may need a diagnosis first: the same symptom can come from many causes, and a serious one such as engine failure is not fixed by a cheap part. They are not a forecast of what your Optima will need. Ranges are US estimates for all makes.

This model year has an engine recall in NHTSA's data. Before you pay for an engine repair, check the recalls and ask the dealer about warranty extensions for your VIN. Those repairs can be free.
