Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 1.97%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Coil spring fractured or broken 1.67%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre cut reaching ply or cords 1.02%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre tread below 1.6mm 0.66%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Windscreen washer fluid insufficient 0.45%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Suspension ball joint excessively worn 0.43%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Common advisories
Tyre worn close to legal limit (7.57%) · Brake disc pitted or scored (2.84%) · Brake pads wearing thin (1.39%) · Tyre slightly damaged or cracking (1.34%) · Engine oil leak, not excessive (1.17%) · Nail in tyre, monitor (1.15%)
