Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 3.17%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Anti-roll bar linkage dust cover unsealed 1.59%
A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.
Tyre tread below 1.6mm 1.59%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 1.49%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Headlamp aim set too low 1.4%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Brake pads worn below 1.5mm 1.4%
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 (12.42%) · Exhaust has minor gas leak (4.67%) · Brake disc pitted or scored (4.3%) · Coil spring showing some corrosion (3.83%) · Brake pads wearing thin (3.83%) · Engine oil leak, not excessive (3.73%)
