2017 Renault Koleos MOT pass rate: 82.6% (1,984 tests)
Is the 2017 Koleos getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 83.4% -2.3 vs same-age |
|
| 2024 | 81.9% -2.0 vs same-age |
|
| 2025 | 82.5% +0.1 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 Koleos?
