2018 Isuzu D-Max MOT pass rate: 79.3% (11,506 tests)
Is the 2018 D-Max getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 82.0% -6.1 vs same-age |
|
| 2024 | 78.4% -7.9 vs same-age |
|
| 2025 | 77.4% -7.4 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 D-Max?
