2018 Lexus RX problems: engine and transmission complaints and recalls
39% of relevant owner complaints on the 2018 Lexus RX are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.
Better than 56% of the 1,790 model years we track (2010–2023).
Excludes 3 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 36%).
Does the 2018 Lexus RX have fuel system problems?
More than most. The pattern is elevated rather than severe. 17 of 44 relevant complaints filed with NHTSA about the 2018 Lexus RX concern the engine, transmission or fuel system (39%), and the largest group is filed under fuel/propulsion system (9). For comparison, the 2017 scores 31% and the 2019 scores 51%. On a test drive, check for hard starts, stalling, hesitation, a fuel smell or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
