Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 1.74%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Wiper blade not clearing windscreen 1.45%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
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.
Tyre tread below 1.6mm 0.98%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
LED or HID headlamp cleaner inoperative 0.62%
Without a working cleaner, dirt can build up on LED or HID lenses and reduce light output, so repair is needed.
Tyre tear from structural failure 0.53%
A tear in the tyre's structure means it can fail suddenly, so it must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (11.68%) · Tyre slightly damaged or cracking (4.84%) · Brake disc pitted or scored (2.7%) · Tyre has a shallow cut (2.14%) · Tyre worn close to legal limit (1.76%) · Brake discs showing some wear (1.61%)
