2018 Ford S-Max MOT pass rate: 84.4% (7,103 tests)
Is the 2018 S-Max getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 85.1% -3.0 vs same-age |
|
| 2024 | 83.5% -2.7 vs same-age |
|
| 2025 | 84.6% -0.2 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 S-Max?
