Best years to buy used
2016–2022 (4th gen)The strongest generation for used buyers. The 3.5L V6 is proven and durable. Hybrid variant (RX 450h) adds complexity but has also proven its long-term reliability. Low NHTSA complaints throughout this generation.
2010–2015 (3rd gen)Extremely solid. The 3.5L V6 and hybrid powertrain are both well-documented by this point. Strong reliability record at high mileage.
Years to think twice about
2023 (3rd gen hybrid complexity)Some early complaints on the 450h+ plug-in hybrid system. Too early for a full reliability verdict on the newest variant.

Common problems to know
Sunroof glass (multiple years): Known to crack or fail on some examples. Check the sunroof before buying.
Electrical niggles: Minor and infrequent compared to German competitors. Generally software-resolvable.
Brake actuator (2010–2015 hybrid): Occasional complaints but not widespread. Worth asking about service history.
Bottom line
A 2016–2022 Lexus RX is one of the best used luxury SUV buys available — premium feel, Toyota reliability underneath, and lower maintenance costs than comparable German rivals.
