Terracan: a below-average pass rate worth digging into
Across 1,996 MOT tests, the Terracan returns 64.8% first-time pass — well below the UK fleet average. The single most-logged Major fail is a number-plate lamp out. A worn steering ball joint and a defective headlamp lens round out the top three. Average tested mileage sits at 114,223, 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 Terracan?
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 Terracan 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.
