2017 Lexus NX MOT pass rate: 93.1% (11,165 tests)
Is the 2017 NX getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 94.3% +8.5 vs same-age |
|
| 2024 | 92.6% +8.8 vs same-age |
|
| 2025 | 92.4% +10.1 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

What mileage is too high for a 2017 NX?
