Hymer: middle-of-the-pack on first-time pass

Across 1,658 MOT tests, the Hymer returns 78.4% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is headlamp aim out of spec. A split CV-joint boot and wipers that don't clear the screen round out the top three. Average tested mileage sits at 57,399, 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 Hymer?

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 Hymer 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.
