Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 3.15%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Registration plate lamp not working 2.47%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Anti-roll bar linkage dust cover unsealed 2.25%
A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.
Tyre ply or cords exposed 1.92%
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 1.54%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Brake pads worn below 1.5mm 1.54%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Common advisories
Tyre worn close to legal limit (12.79%) · Tyre slightly damaged or cracking (7.38%) · Brake pads wearing thin (7.24%) · Brake disc pitted or scored (6%) · Brake discs showing some wear (3.55%) · Child seat limits belt inspection (2.83%)
