Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 7.75%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Brake pads worn below 1.5mm 2.98%
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 2.23%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre cut reaching ply or cords 1.45%
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 1.24%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Rigid brake pipe excessively corroded 0.92%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Common advisories
Brake pads wearing thin (13.64%) · Tyre worn close to legal limit (11.39%) · Brake disc pitted or scored (11.3%) · Tyre slightly damaged or cracking (10.06%) · Brake pipes corroded and greasy (6.5%) · Brake discs showing some wear (2.46%)
