Top failures
Brake pads worn below 1.5mm 1.6%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre cut reaching ply or cords 1.15%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Brake effort excessively fluctuating 0.62%
Uneven braking through each wheel turn can make stopping unpredictable, so the brakes need inspecting and repair.
Airbag warning lamp shows fault 0.53%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Windscreen washers not working 0.5%
Without working washers the windscreen cannot be cleaned while driving, which is a safety risk in dirty weather.
Tyre tread below 1.6mm 0.42%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Brake disc pitted or scored (6.1%) · Brake pads wearing thin (5.01%) · Tyre worn close to legal limit (4.76%) · Tyre slightly damaged or cracking (2.32%) · Child seat limits belt inspection (1.18%) · Nail in tyre, monitor (1.06%)
