Top failures
Brake pads worn below 1.5mm 2.44%
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 2.36%
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 1.03%
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 0.95%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too low 0.72%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre pressure monitoring system faulty 0.53%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Common advisories
Tyre worn close to legal limit (8.18%) · Brake pads wearing thin (6.2%) · Tyre slightly damaged or cracking (2.93%) · Brake disc pitted or scored (2.66%) · Brake discs showing some wear (1.48%) · Nail in tyre, monitor (1.18%)
