The VIN is on the listing, the driver’s door jamb, and the bottom of the windshield on the driver’s side.

Does the 2020 Lexus NX have engine problems?

Owner complaints say yes, as a model-year pattern. 14 of 27 relevant complaints filed with NHTSA about the 2020 Lexus NX concern the engine, transmission or fuel system (54%), and the largest group is filed under engine (8). For comparison, the 2019 scores 36%. On a test drive, check for stalling, loss of power, rough idle, oil consumption 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.

FUEL/PROPULSION SYSTEM08/31/2026
I have been noticing sluggish acceleration since the end of 2024, specially when fuel falls below or equal to half tank, I took my vehicle to the dealership several times and specifically instructed them to inspect my acceleration issue but every time said no issue on fuel pump. They even failed to reproduce my problem…
