Lexus has quietly built a reputation for quality and reliability in the luxury SUV market, and the RX (Mk4, 2016-2022) is a prime example. While it doesn’t dominate sales charts, the RX consistently scores highly in customer satisfaction surveys, offering a unique blend of refinement, dependability, and distinctive design that sets it apart from European competitors. If you’re seeking an alternative to the typical luxury SUV, the RX deserves consideration.
A Quarter-Century of Innovation
The Lexus RX has been a fixture in the premium SUV segment for 25 years, pioneering the hybrid SUV concept with the second-generation model in 2004. The RX has become a cornerstone of Lexus’s lineup, accounting for 30% of all sales by the time the Mk4 arrived. Despite strong owner loyalty, the RX often flies under the radar for used car buyers, making it a potentially overlooked gem.
Model History and Options
The Mk4 RX debuted in UK showrooms in January 2016, offering two core options: the RX 200t with a turbocharged 2.0-liter four-cylinder engine (234bhp) and the RX 450h, a hybrid combining a 3.5-liter V6 (259bhp) with an electric motor. Both were available in front-wheel or all-wheel drive. In 2018, Lexus introduced the RX 450hL, a seven-seater variant stretched by 11cm, though third-row space is limited to children. A 2020 facelift brought styling updates, improved infotainment, stiffer chassis, and enhanced driver-assistance systems before the Mk5 took over in 2022.
What to Buy on the Used Market
Finding a used RX 200t is rare. The five-seat RX 450h dominates the market, while the seven-seat RX 450hL is less common. All trims come well-equipped, including adaptive cruise control, parking sensors, and heated seats. Luxury trims add larger infotainment screens and wireless charging. The Premier trim offers a high-end experience with a premium sound system, panoramic roof, and head-up display.
Key Alternatives
The RX competes with formidable rivals like the Mercedes GLE, Audi Q7, Porsche Cayenne, Range Rover Sport, and BMW X5, many of which offer plug-in hybrid options. The Audi Q7 and Range Rover Sport stand out for their standard seven-seat configurations, while the Cayenne and BMW X5 provide superior driving dynamics. The Volvo XC90 is another strong contender, blending luxury with practicality.
Common Issues and What to Check
- Catalytic Converter Theft: RX models are frequent targets for catalytic converter thieves; inspect for underside damage.
- Tire Wear: Michelin Cross Climate tires are a popular choice among owners for their all-weather performance.
- Fuel Economy: While Lexus claims over 50 mpg with the RX 450h, real-world figures typically range from 35-38 mpg.
- Wheel Lacquer: Diamond-cut wheel lacquer can corrode; refurbishment costs around £100 per wheel.
- Interior Design: The RX interior is high-quality but may not appeal to those accustomed to German-style interiors.
Running Costs and Maintenance
RX models require annual servicing (Intermediate at £340 or Full at £660), with brake fluid replacement every two years. Hybrid models have a separate inverter coolant that needs replacing after 15 years or 150,000 miles. The RX’s chain-driven engine eliminates the need for cambelt replacements. The original warranty covered three years/60,000 miles (hybrid powertrain extended to five years/60,000 miles).
Recalls and Reliability
The Mk4 RX has been recalled twice: once in 2016 for faulty airbags and again in 2020 for a potential fuel pump issue. Despite these minor recalls, the RX has maintained a strong reputation for reliability.
Owner Satisfaction
Lexus consistently ranks high in Driver Power surveys. The RX Mk4 secured third place in the 2023 New Car poll and 11th in the Used Car survey, praised for its reliability, practicality, and interior quality. However, running costs and fuel economy were noted as drawbacks.
Verdict
The Lexus RX (2016-2022) offers a compelling alternative in the premium SUV segment. While not the most dynamic choice, it excels in refinement, reliability, and distinctive design. Its high owner satisfaction ratings and well-equipped trims make it a smart purchase for those prioritizing comfort and dependability over outright performance.
