Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 1.67%
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 1.35%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre ply or cords exposed 1.24%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 0.84%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
LED or HID headlamp cleaner inoperative 0.51%
Without a working cleaner, dirt can build up on LED or HID lenses and reduce light output, so repair is needed.
Tyre bulge from structural failure 0.49%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Common advisories
Tyre worn close to legal limit (12.06%) · Tyre slightly damaged or cracking (5.33%) · Brake disc pitted or scored (2.12%) · Tyre worn close to legal limit (1.74%) · Tyre has a shallow cut (1.74%) · Brake discs showing some wear (1.31%)
