The picture
Grand Cherokee: a below-average pass rate worth digging into
Across 2,590 MOT tests, the Grand Cherokee returns 69.5% first-time pass — well below the UK fleet average. The single most-logged Major fail is a number-plate lamp out. The strength or continuity of the load bearing and windscreen damage round out the top three. Average tested mileage sits at 116,727, 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 Cherokee?
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 Cherokee 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.
