Focus St Ecoblue: a strong MOT record by UK norms
Across 923 MOT tests, the Focus St Ecoblue returns 85.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a tyre with the cords showing. A seriously damaged tyre and a seriously damaged tyre round out the top three. Average tested mileage sits at 28,844, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a Focus ST Ecoblue?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
