Average for cars of the same age and mileage
Top failures
Shock absorber serious fluid leak 1.33%
A shock absorber leaking heavily has likely lost its damping, so the car will handle and brake less safely.
Tyre tread below 1.6mm 1.3%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.09%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Engine warning light inoperative or lit 0.88%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Airbag warning lamp shows fault 0.62%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Tyre ply or cords exposed 0.53%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (7.96%) · Brake pads wearing thin (3.68%) · Tyre slightly damaged or cracking (2.62%) · Nail in tyre, monitor (2%) · Tyre has a shallow cut (1.3%) · Tyre worn close to legal limit (0.91%)
