Is the 2015 500X getting worse?

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

Test year	Pass rate
2023	79.9% -0.6 vs same-age
2024	74.1% -4.4 vs same-age
2025	71.5% -5.5 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 Fiat 500X reliable?

2015-registered examples passed 75.2% of their MOT tests (21,117 tests, 2023–2025), -3.5 points versus all UK cars registered in the same year. At roughly 11 years old with a median 63,105 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2015 500X?

The median tested example shows 63,105 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 2015 500X?

In this cohort petrols pass 77.1% of tests against 72.7% 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.
