Arona Xcellence Lux Ecotsi S-A: a strong MOT record by UK norms

Across 1,316 MOT tests, the Arona Xcellence Lux Ecotsi S-A returns 91.6% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is excessive fluctuation in brake effort through each wheel. Windscreen damage and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 20,035, 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 an Arona Xcellence Lux Ecotsi S A?

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 an Arona Xcellence Lux Ecotsi S A 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.
