Sovereign: middle-of-the-pack on first-time pass

Across 468 MOT tests, the Sovereign returns 75.4% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is the strength or continuity of the load bearing. Windscreen damage and a torn suspension dust cover round out the top three. Average tested mileage sits at 88,569, 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 Sovereign?

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.

If you own a Sovereign and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
