Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 2.41%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre tread below 1.6mm 2.29%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.31%
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 0.98%
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 0.82%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Wiper blade not clearing windscreen 0.65%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Common advisories
Tyre worn close to legal limit (12.77%) · Brake pads wearing thin (7.89%) · Suspension arm pin/bush showing wear (4.4%) · Tyre slightly damaged or cracking (3.67%) · Brake disc pitted or scored (3%) · Child seat limits belt inspection (2.5%)
