2019 Mercedes-Benz X MOT pass rate: 83.7% (4,772 tests)
Is the 2019 X getting worse?
Pass rate of 2019-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 84.4% -5.4 vs same-age |
|
| 2024 | 83.2% -5.1 vs same-age |
|
| 2025 | 83.4% -3.6 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 2019 X?
