Top failures
Coil spring fractured or broken 2.96%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre tread below 1.6mm 1.62%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Engine warning light inoperative or lit 1.53%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Tyre ply or cords exposed 1.26%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Suspension arm pin/bush excessively worn 1.26%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Suspension ball joint excessively worn 1.17%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Common advisories
Tyre worn close to legal limit (13.73%) · Suspension arm pin/bush showing wear (11.67%) · Engine oil leak, not excessive (7.81%) · Brake pads wearing thin (4.85%) · Brake disc pitted or scored (4.67%) · Sub-frame showing corrosion (3.59%)
