Hyundai Sonata Factory Maintenance Schedule

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

The service schedule on a Hyundai Sonata is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

How often does a Hyundai Sonata need servicing?
