Average for cars of the same age and mileage
Top failures
Tyre cut reaching ply or cords 1.34%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Wiper blade not clearing windscreen 1.14%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 1.06%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 0.92%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre ply or cords exposed 0.84%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Windscreen washer fluid insufficient 0.61%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Common advisories
Tyre worn close to legal limit (10.56%) · Brake pads wearing thin (6.33%) · Nail in tyre, monitor (2.12%) · Child seat limits belt inspection (2.06%) · Brake disc pitted or scored (1.96%) · Tyre worn close to legal limit (1.6%)
