2018 Tesla Model X MOT pass rate: 81.4% (4,125 tests)
Is the 2018 Model X getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 82.7% -5.3 vs same-age |
|
| 2024 | 80.5% -5.7 vs same-age |
|
| 2025 | 81.0% -3.7 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 2018 Model X?
