2018 Lexus NX problems: engine and transmission complaints and recalls
44% of relevant owner complaints filed with NHTSA on the 2018 Lexus NX are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 55% of the 1,790 model years we track (2010–2023).
Does the 2018 Lexus NX have fuel system problems?
Owner complaints say yes, as a model-year pattern. 11 of 26 relevant complaints filed with NHTSA about the 2018 Lexus NX concern the engine, transmission or fuel system (44%), and the largest group is filed under fuel/propulsion system (8). For comparison, the 2017 scores 19% and the 2019 scores 36%. 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.
