The picture
Trax: middle-of-the-pack on first-time pass
Across 1,921 MOT tests, the Trax returns 74.1% first-time pass — below the UK fleet average. The single most-logged Major fail is a torn suspension dust cover. A missing suspension dust cover and a broken or weak spring round out the top three. Average tested mileage sits at 75,605, 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 Trax?
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 Trax 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.
