Average for cars of the same age and mileage
Top failures
Tyre tread below 1.6mm 1.57%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 0.8%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre ply or cords exposed 0.4%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Brake pads worn below 1.5mm 0.36%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Engine warning light inoperative or lit 0.25%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Headlamp aim set too high 0.22%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Common advisories
Tyre worn close to legal limit (8.78%) · Brake pads wearing thin (4.81%) · Spring mounting corroded, not weakened (1.65%) · Nail in tyre, monitor (1.39%) · Tyre slightly damaged or cracking (1.3%) · Brake disc pitted or scored (1.19%)
