Top failures
Coil spring fractured or broken 3.06%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre tread below 1.6mm 1.98%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
CV joint boot split or insecure 1.98%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Tyre ply or cords exposed 1.62%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Engine warning light inoperative or lit 1.35%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Carbon monoxide high after fast idle 1.26%
High carbon monoxide can point to engine or catalytic converter faults, so ask for diagnosis before buying.
