Is the 2017 I30 getting worse?

Pass rate of 2017-registered cars across recent test years:

Test year	Pass rate
2023	86.9% +1.1 vs same-age
2024	83.6% -0.2 vs same-age
2025	84.2% +1.8 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 2017 Hyundai I30 reliable?

2017-registered examples passed 84.9% of their MOT tests (20,083 tests, 2023–2025), +0.9 points versus all UK cars registered in the same year. At roughly 9 years old with a median 52,638 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 I30?

The median tested example shows 52,638 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.

Should I buy the petrol or diesel 2017 I30?

In this cohort petrols pass 86.3% of tests against 82.5% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
