2016-2024 (3.5L V6 / 2.4L turbo / hybrid) Lexus RX — 3.5L V6 (2GR), 2.4L turbo (2023+) or 350h/450h hybrid; 0W-20 synthetic; 8-speed auto / eCVT.
Answer: Timing CHAIN — no scheduled replacement.
| Belt or chain | Timing chain — no scheduled replacement |
|---|---|
| Engine | 3.5L V6 (2GR), 2.4L turbo (2023+) or 350h/450h hybrid; 0W-20 synthetic; 8-speed auto / eCVT |
| Interference engine? | Not flagged in our data — confirm in your manual |
The Lexus RX 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.
Lexus RX note: Mechanically a luxury Toyota Highlander/Camry underneath — very low-maintenance, chain-driven, plugs at ~120k. The hybrid adds an inverter-coolant item but no extra engine burden.
