2017 Tesla Model X MOT pass rate: 81.4% (5,968 tests)
Is the 2017 Model X getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 83.7% -2.1 vs same-age |
|
| 2024 | 80.7% -3.2 vs same-age |
|
| 2025 | 79.6% -2.7 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 Model X?
