Is the 2015 I40 getting worse?

Pass rate of 2015-registered cars across recent test years:

Test year	Pass rate
2023	79.6% -1.0 vs same-age
2024	77.5% -1.0 vs same-age
2025	77.6% +0.6 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 2015 Hyundai I40 reliable?

What mileage is too high for a 2015 I40?

The median tested example shows 88,442 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.
