In 2025, 34,019 Fiat 500X cars had a regular MOT in Great Britain. 72% passed first time, compared with 77% for all cars of the same ages, which makes the 500X worse than average. Adjusted for age, it ranks 189 of the 217 most-tested car models.
That comparison matters: older cars fail more often, so a raw pass rate flatters models that are mostly young. We compare each model against every car on the road at the same age.
Pass rate by age
At 3 years old, 89% of 500Xs passed first time (all cars that age: 88%). By 10 years, that figure is 66% (all cars: 72%). It trails the average car at most ages, most noticeably at 9 years (8 points behind).

What fails most on a Fiat 500X

What to check when buying a used 500X
Based on where the 500X fails more often than other cars, these are the checks worth making before you buy:
- Steering: Feel for play or knocking through the wheel, and check power-steering fluid isn’t leaking. More
- Tyres: Check tread across the whole width (uneven wear hints at alignment or suspension faults), and look for cuts, bulges and mismatched brands. Repair guide
- Emissions and leaks: Look for oil and coolant leaks underneath, listen for exhaust blows on a cold start, and watch for smoke when revving. Repair guide
Then check the individual car: its own MOT history will show whether it follows the pattern. A car with repeated advisories in the same weak area is more likely to fail its next test.
