Top failures
Tyre tread below 1.6mm 1.9%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Airbag warning lamp shows fault 1.51%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Tyre cut reaching ply or cords 1.31%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Windscreen washer fluid insufficient 1.26%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Wiper blade not clearing windscreen 1.09%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre ply or cords exposed 0.59%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre slightly damaged or cracking (11.74%) · Tyre worn close to legal limit (11.61%) · Brake disc pitted or scored (7.45%) · Brake pads wearing thin (4.69%) · Road wheel slightly distorted (2.5%) · Child seat limits belt inspection (1.88%)
