Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 3.19%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre tread below 1.6mm 1.97%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 1.82%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre cut reaching ply or cords 1.27%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Anti-roll bar linkage dust cover unsealed 0.91%
A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.
ABS warning lamp shows a fault 0.75%
A lit ABS warning means the anti-lock system may not work, so wheels could lock during emergency braking.
Common advisories
Tyre worn close to legal limit (12.3%) · Brake disc pitted or scored (5.88%) · Tyre slightly damaged or cracking (4.4%) · Brake pads wearing thin (3.4%) · Brake discs showing some wear (2.48%) · Wheel bearing slight play (2.41%)
