Transit Custom: above-average pass rates, with caveats
Across 86,593 MOT tests, the Transit Custom returns 80.4% first-time pass — above the UK fleet average. The single most-logged Major fail is windscreen damage. Wipers that don't clear the screen and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 64,946, 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 Transit Custom?
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 Transit Custom 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.
