Here’s a comprehensive list of common issues and complaints for the 2019 Lexus RX450hL, organized by category and powertrain configuration.

The 2019 Lexus RX 450hL is a luxury crossover SUV known for its comfortable ride, fuel efficiency (thanks to its hybrid powertrain), and upscale interior. The “L” designation signifies a longer wheelbase and a third-row seat, albeit a somewhat cramped one. The sole powertrain option for the 450hL is a 3.5-liter V6 engine paired with a hybrid system. The engine produces 259 horsepower and 247 lb-ft of torque, while the total system output is 308 horsepower. Owners generally appreciate the smooth and quiet ride, the high-quality interior materials, and the reliability associated with the Lexus brand. Criticisms often include the less-than-spacious third-row seating, the somewhat dated infotainment system (controlled by a touchpad), and the higher price point compared to some competitors.
