Convoy: a below-average pass rate worth digging into
Across 2,525 MOT tests, the Convoy returns 61.2% first-time pass — well below the UK fleet average. The single most-logged Major fail is the strength or continuity of the load bearing. A number-plate lamp out and structural corrosion round out the top three. Average tested mileage sits at 91,264, 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.
Top ten reasons for rejection.
- 01
The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired
311 occurrences · 12.3% of tests
- 02
A rear registration plate lamp or light source missing or inoperative in the case of multiple lamps or light sources
237 occurrences · 9.4% of tests

143 occurrences · 5.7% of tests

Windscreen or window damaged or seriously discoloured but not adversely affecting driver's view

Wiper blade missing or obviously not clearing the windscreen
121 occurrences · 4.8% of tests

Counts cover Major and Dangerous defects logged at test. Advisory items excluded so this shows why a car was rejected, not just what the tester flagged in passing.

Buying or keeping a Convoy?
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 Convoy 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.
