2017 Hyundai I800 MOT pass rate: 77.2% (3,995 tests)
Is the 2017 I800 getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 78.8% -6.9 vs same-age |
|
| 2024 | 76.1% -7.7 vs same-age |
|
| 2025 | 76.7% -5.6 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 2017 I800?
