Is the 2018 I20 getting worse?

Pass rate of 2018-registered cars across recent test years:

Test year	Pass rate
2023	91.9% +3.8 vs same-age
2024	89.4% +3.2 vs same-age
2025	88.4% +3.6 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.

FAQs

Is a 2018 Hyundai I20 reliable?

2018-registered examples passed 89.9% of their MOT tests (25,643 tests, 2023–2025), +3.5 points versus all UK cars registered in the same year. At roughly 8 years old with a median 35,636 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2018 I20?

The median tested example shows 35,636 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
