Grandis: a below-average pass rate worth digging into
Across 1,884 MOT tests, the Grandis returns 62.8% first-time pass — well below the UK fleet average. The single most-logged Major fail is a defective headlamp lens. A number-plate lamp out and headlamp aim out of spec round out the top three. Average tested mileage sits at 123,094, 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 Grandis?
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 Grandis 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.
