Top failures
Coil spring fractured or broken 6.57%
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 3.34%
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 1.71%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 1.65%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Rigid brake pipe excessively corroded 1.44%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Tyre cut reaching ply or cords 1.25%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Common advisories
Tyre worn close to legal limit (12.63%) · Brake pads wearing thin (11.11%) · Brake pipes corroded and greasy (8.65%) · Tyre slightly damaged or cracking (8.63%) · Brake disc pitted or scored (7.36%) · Suspension arm pin/bush showing wear (4.04%)
