About the Lexus RX
AI-generatedThe Lexus RX is a premium mid-size SUV that has been a cornerstone of the Lexus lineup since 1998, combining Japanese reliability with luxury refinement. Available in both petrol and hybrid variants (RX 450h), it offers a spacious, beautifully crafted interior with exceptional build quality and a smooth, comfortable ride. The RX is particularly popular in the UK for its reputation for bulletproof reliability, low running costs for its class, and strong residual values. The fourth generation (2015-2022) brought striking angular styling and improved hybrid efficiency, while the fifth generation (2022-present) features a more driver-focused design with enhanced technology. The RX typically seats five in excellent comfort, though a seven-seat RX L variant has been available. Known for its whisper-quiet cabin, supple ride quality, and generous standard equipment, the RX appeals to buyers seeking a premium SUV without the maintenance concerns often associated with German rivals.

Owner Tips
- 1Always maintain the full Lexus service history to retain the 10-year hybrid battery warranty and maximize resale value
- 2Clean alloy wheels regularly to prevent brake dust from baking on and damaging the finish
- 3Use premium 98 RON fuel for best performance and economy, though 95 RON is acceptable
- 4Take time to learn the infotainment system when stationary to avoid distraction while driving
- 5Check hybrid battery warranty status when buying used - full Lexus history required for continuation
- 6Consider extended warranty coverage through Lexus for older models, as it's excellent value
- 7The RX drives best in Comfort mode for typical use; Sport mode makes the ride unnecessarily firm
- 8Keep an eye on tyre wear as the RX's weight can accelerate wear, especially on front tyres
