Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.68%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 1.34%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre cut reaching ply or cords 0.78%
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 0.77%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre bulge from structural failure 0.74%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Windscreen washer fluid insufficient 0.66%
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 (10.26%) · Brake pads wearing thin (7.86%) · Tyre slightly damaged or cracking (6.59%) · Brake disc pitted or scored (2.61%) · Nail in tyre, monitor (2.37%) · Brake discs showing some wear (2.24%)
