2018 Lexus NX problems: engine and transmission complaints and recalls
HIGH COMPLAINT SIGNAL
44%
11 of 26 relevant owner complaints are about the engine, transmission or fuel system
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 1,789 model years we track (2010–2023).
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.
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2018 Lexus NX
Ask the seller whether the fuel system has ever been repaired or replaced, and whether the car has shown hard starts, stalling, hesitation, a fuel smell or a check-engine light.
Drive it from a cold start and long enough to warm up. Many fuel system faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the fuel system.
1 recall campaign on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A fuel system already replaced under warranty is a different car from one that was not.

Should I buy a 2018 Lexus NX?
That depends on the car in front of you, not just the model year. The 2018 Lexus NX has an elevated fuel system complaint pattern, so treat it as a car that needs proof: service records showing fuel system work, a cold-start test drive, and an independent pre-purchase inspection focused on the fuel system. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
