Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.77%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 0.94%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Brake pads worn below 1.5mm 0.57%
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 0.51%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Headlamp aim set too high 0.34%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Wiper blade not clearing windscreen 0.34%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Common advisories
Tyre worn close to legal limit (11.01%) · Brake pads wearing thin (5.28%) · Brake disc pitted or scored (4.58%) · Tyre slightly damaged or cracking (4.04%) · Nail in tyre, monitor (2.18%) · Tyre has a shallow cut (1.73%)
