Average for cars of the same age and mileage
Top failures
Tyre cut reaching ply or cords 0.98%
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 0.6%
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 0.51%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 0.45%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too low 0.35%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre pressure monitoring system faulty 0.21%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Common advisories
Tyre worn close to legal limit (10.24%) · Tyre slightly damaged or cracking (4.07%) · Tyre worn close to legal limit (1.82%) · Brake disc pitted or scored (1.7%) · Child seat limits belt inspection (1.4%) · Brake pads wearing thin (1.4%)
