A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.
500X MOT pass rate by age
The same 2025 tests split by the car's age at test.
Fiat 500X cars aged 3 to 5 years passed 86.9% of MOT tests. For cars aged 6 to 10 years that fell to 69.3%, a drop of 17.6 percentage points.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years | 6,401 | 86.9% | 14.6 pts above |
| 6 to 10 years | 29,579 | 69.3% | 3 pts below |
That is a steep decline with age, so the headline rate flatters older examples. The UK average of 72.3% covers cars of every age, so compare like with like.
