Average for cars of the same age and mileage
Top failures
Tyre ply or cords exposed 1.69%
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 1.62%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Parking brake efficiency below minimum 0.66%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Tyre cut reaching ply or cords 0.63%
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 0.44%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too high 0.4%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Common advisories
Tyre worn close to legal limit (4.27%) · Tyre slightly damaged or cracking (2.43%) · Brake disc pitted or scored (1.25%) · Nail in tyre, monitor (0.77%) · Brake pads wearing thin (0.66%) · Tyre has a shallow cut (0.63%)
