Top failures
Suspension ball joint excessively worn 3.67%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Tyre tread below 1.6mm 1.55%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.33%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Coil spring fractured or broken 1.12%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Brake pads worn below 1.5mm 1.1%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Diesel engine warning light faulty 0.93%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Common advisories
Tyre worn close to legal limit (12.43%) · Brake pads wearing thin (7.26%) · Suspension ball joint slight play (6.16%) · Brake disc pitted or scored (4.41%) · Brake discs showing some wear (3.41%) · Tyre slightly damaged or cracking (3.09%)
