2020-2024 (DN8) Hyundai Sonata — 2.5L NA, 1.6L turbo, or 2.5L turbo (N-Line); 0W-20 / 0W-30 (2.5T); 8-speed auto / 8-speed DCT.
Answer: Timing CHAIN — no scheduled replacement.
| Belt or chain | Timing chain — no scheduled replacement |
|---|---|
| Engine | 2.5L NA, 1.6L turbo, or 2.5L turbo (N-Line); 0W-20 / 0W-30 (2.5T); 8-speed auto / 8-speed DCT |
| Interference engine? | Not flagged in our data — confirm in your manual |
The Hyundai Sonata uses a timing chain designed to last the engine's lifetime, so there's no scheduled replacement — one less recurring service to budget for than belt-driven rivals.
Hyundai Sonata note: Same Smartstream chain engines as its Kia K5 twin. Turbo trims need ~45k plugs; the N-Line uses an 8-speed dual-clutch. Watch the short second coolant cycle after the long first one.
