Top failures
Tyre tread below 1.6mm 3.01%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Suspension ball joint excessively worn 2.06%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Coil spring fractured or broken 1.9%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Diesel engine warning light faulty 1.36%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Tyre ply or cords exposed 1.29%
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 1.26%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Common advisories
Tyre worn close to legal limit (15.42%) · Brake disc pitted or scored (6.27%) · Brake pads wearing thin (6.26%) · Suspension ball joint slight play (4.01%) · Brake discs showing some wear (2.86%) · Tyre slightly damaged or cracking (2.79%)
