This page covers 2 recalls, 18 owner complaints and NHTSA crash-test ratings for the 2018 Lexus Rx350.
4/5 Overall
NHTSA 5-Star Safety Rating
Throttle response is the dominant theme in 2018 RX350 complaints. Owners frequently report inconsistent acceleration behavior, sometimes the engine hesitates for several seconds after pressing the accelerator, and other times it surges with more power than expected. A few owners also describe the instrument cluster displaying a pedal obstruction warning during these hesitation events. The fuel and propulsion system complaints overlap with this pattern, pointing to throttle and engine response as the core concern. A single report describes complete brake pedal failure with the pedal going to the floor and the vehicle not slowing, though this appears isolated. Separate isolated reports mention premature tire wear on OEM Bridgestone tires at around 14,000 miles and a loose wiper linkage bolt causing the passenger-side wiper to stop working.
