In 2025, 28,343 Lexus NX cars had a regular MOT in Great Britain. 90% passed first time, compared with 80% for all cars of the same ages, which makes the NX better than average. Adjusted for age, it ranks 18 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 4 years old, 92% of NXs passed first time (all cars that age: 87%). By 11 years, that figure is 86% (all cars: 69%). It beats the average car at every age with enough data, from 4 to 11 years.

What to check when buying a used NX
Based on where the NX fails more often than other cars, these are the checks worth making before you buy:
- Plates and VIN: Check the number plates are legal and the VIN matches the V5C logbook. More
- Seat belts and airbags: Pull every belt out fully and let it retract, check the buckles latch, and make sure the airbag light goes out after starting. More
- Visibility: Check the windscreen for chips in the driver’s view, the wipers for smearing and the washers for working jets. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
