Top failures
Wiper blade not clearing windscreen 4.16%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Brake pads worn below 1.5mm 1.58%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre tread below 1.6mm 1.47%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.18%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre ply or cords exposed 0.63%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Windscreen washer fluid insufficient 0.59%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Common advisories
Tyre worn close to legal limit (11.16%) · Tyre slightly damaged or cracking (9.87%) · Brake pads wearing thin (6.93%) · Brake disc pitted or scored (2.79%) · Brake discs showing some wear (2.18%) · Child seat limits belt inspection (2.15%)
