Which cars fail their MOT most on suspension?

How this is worked out

Every figure is computed from the full DVSA MOT test and defect record, not a survey or a poll. Rates are the share of MOT tests that end in a failure (or a pass); area figures count that area's recorded defects against tests taken. A model is only ranked once it clears a minimum test count, so a single unlucky batch cannot distort a list. Motorcycles, which share the MOT dataset, are excluded so these are genuine car rankings. Age is the strongest driver of MOT failure, so older models and vans naturally rank higher. Figures describe how a model performs across the fleet; they are not a diagnosis of any individual car.
