Grand Cherokee: above-average pass rates, with caveats

Across 7,411 MOT tests, the Grand Cherokee returns 84.2% first-time pass — above the UK fleet average. The single most-logged Major fail is windscreen damage. Tyre tread under the limit and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 68,843, 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.
