Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 2.76%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Brake pads worn below 1.5mm 1.89%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre cut reaching ply or cords 1.55%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Headlamp aim set too high 0.9%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre tread below 1.6mm 0.88%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 0.5%
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 (10.61%) · Brake pads wearing thin (9.76%) · Brake disc pitted or scored (8.05%) · Tyre slightly damaged or cracking (7.96%) · Child seat limits belt inspection (3.46%) · Nail in tyre, monitor (2.24%)
