Top failures
Coil spring fractured or broken 1.15%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre cut reaching ply or cords 0.97%
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 0.84%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Wiper blade not clearing windscreen 0.78%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre ply or cords exposed 0.72%
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 0.65%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Common advisories
Tyre worn close to legal limit (8.13%) · Brake pads wearing thin (6.96%) · Tyre slightly damaged or cracking (2.15%) · Brake disc pitted or scored (2.15%) · Tyre has a shallow cut (1.9%) · Child seat limits belt inspection (1.72%)
