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.
A timing chain is designed to last the engine's lifetime, so there's no scheduled replacement — one less recurring service to budget for than belt-driven rivals.

When does the Lexus RX timing belt need replacing?
The Lexus RX uses a timing chain, which is designed to last the life of the engine — there is no scheduled replacement interval. Inspect if you hear rattling on cold start.
What happens if a timing belt breaks?
On an interference engine, a snapped timing belt lets the valves and pistons collide, which can destroy the engine. That's why belt replacement intervals are not optional.
