Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 1.48%
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 1.03%
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 0.87%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too high 0.59%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Windscreen washer fluid insufficient 0.48%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Tyre ply or cords exposed 0.46%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (7.3%) · Brake disc pitted or scored (3.11%) · Tyre has a shallow cut (1.32%) · Tyre worn close to legal limit (1.25%) · Tyre slightly damaged or cracking (1.19%) · Nail in tyre, monitor (1.03%)
