Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 0.95%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 0.88%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Wiper blade not clearing windscreen 0.56%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre ply or cords exposed 0.45%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Diesel engine warning light faulty 0.39%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Headlamp aim set too high 0.37%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Common advisories
Tyre worn close to legal limit (6.38%) · Tyre slightly damaged or cracking (1.71%) · Nail in tyre, monitor (1.54%) · Brake pads wearing thin (1.5%) · Child seat limits belt inspection (1.13%) · Tyre worn close to legal limit (1.03%)
