The picture
Grand Voyager: a below-average pass rate worth digging into
Across 2,000 MOT tests, the Grand Voyager returns 64.2% first-time pass — well below the UK fleet average. The single most-logged Major fail is a number-plate lamp out. A weak handbrake and windscreen damage round out the top three. Average tested mileage sits at 117,414, 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 Grand Voyager?
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 Grand Voyager 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.
