2018 Hyundai I30 MOT pass rate: 87.1% (21,805 tests)
Is the 2018 I30 getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 88.3% +0.2 vs same-age |
|
| 2024 | 87.2% +1.0 vs same-age |
|
| 2025 | 85.8% +1.0 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 I30?
