Nsc 50 Wh-C: above-average pass rates, with caveats
Across 496 MOT tests, the Nsc 50 Wh-C returns 81.8% first-time pass — above the UK fleet average. The single most-logged Major fail is a non-functioning shock absorber. A stop-lamp out and brake pads worn below 1.0 mm round out the top three. Average tested mileage sits at 14,494, 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 Nsc 50 WH C?
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 Nsc 50 WH C 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.
