Saxo: a below-average pass rate worth digging into
Across 5,749 MOT tests, the Saxo returns 63.3% 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 split CV-joint boot and a missing CV-joint boot round out the top three. Average tested mileage sits at 74,297, 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

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 Saxo?
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 Saxo 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.
