The 2026 Kia K4’s routine factory schedule centers on 7,500-mile oil changes and tire rotations, with brake, filter, spark plug, and coolant services coming at longer intervals. The engine uses a timing chain rather than a scheduled timing belt, so there is no routine replacement interval for that item.
