After defects were fixed at the test centre
72.2% of Ford Fiesta tests and 80.0% of MINI Hatch tests passed, including defects fixed during the test. This is a different outcome from passing at the first attempt.
What explains the difference?
The clearest difference is suspension: against its own class and age, the Ford Fiesta runs +3.0 items per 100 tests and the MINI Hatch −9.2, so the MINI Hatch has 12.2 fewer per 100 tests (95% interval 12.2 to 12.3).
Each model is compared with its own class and age; the fleets can differ in mileage and use.

At what age does one of them fail more?
The MINI Hatch fails less at 14 of 17 ages where both are tested, and the gap points the same way at every age where it is clear. Across the 4 yearly tests from age 4 to 7, the gaps add up to 30.3 extra failed tests per 100 for the Ford Fiesta (a sum of yearly rates, not the chance of one car failing).

Where do their MOT failures diverge?
The clearest difference is suspension: against its own class and age, the Ford Fiesta runs +3.0 items per 100 tests and the MINI Hatch −9.2, so the MINI Hatch has 12.2 fewer per 100 tests (95% interval 12.2 to 12.3).

If one fails, which is more likely to fail again?
A failure carries about the same extra risk of failing again on both: 11.0 percentage points on the Ford Fiesta, 11.5 on the MINI Hatch.

| After a failed test, % | 39.5 | 34.3 |

Recalls, other countries and running costs, side by side
DVSA lists 32 recall campaigns matched to the Ford Fiesta and 27 to the MINI Hatch; more campaigns do not by themselves mean a less reliable car. Abroad, compare each model with that country's own average, because pass rates do not carry across rulebooks. Repair bills are catalogue estimates, not quotes.
