Lexus RX 350/450h High Mileage Guide – 100,000 km+ Malaysia
RX 350 at 100,000 km: change ATF, all AWD diff and transfer fluids, 6 spark plugs, coolant flush, brake fluid, and suspension inspection. RX 450h: add inverter coolant flush and hybrid battery health test. Both: inspect front upper suspension arms, wheel bearings, and timing chain. A well-maintained RX 350 runs reliably to 200,000 km; RX 450h regularly exceeds 250,000 km.

RX High Mileage Tips
- RX is well-known for exceeding 200,000 km reliably — key is consistent servicing
- At 100,000 km: replace front upper control arm (common wear), check ATF, spark plugs
- At 150,000 km: coolant flush, all suspension bushings, rear shock absorbers
