Top failures
Coil spring fractured or broken 2.57%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Wiper blade not clearing windscreen 1.37%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre ply or cords exposed 1.33%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 1.25%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Engine warning light inoperative or lit 1.21%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Road wheel fractured or welded defect 0.9%
A fractured wheel can fail suddenly and cause loss of control, so it must be replaced before driving.
Common advisories
Tyre worn close to legal limit (10.22%) · Brake disc pitted or scored (5.8%) · Tyre slightly damaged or cracking (4.37%) · Brake pads wearing thin (4.25%) · Engine oil leak, not excessive (3.76%) · Shock absorber light oil misting (2.64%)
