Top failures
Wiper blade not clearing windscreen 1.87%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 1.29%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 0.9%
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 0.77%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Headlamp aim set too low 0.58%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Windscreen washer fluid insufficient 0.58%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Common advisories
Brake disc pitted or scored (11.03%) · Tyre worn close to legal limit (10.38%) · Brake pads wearing thin (4.13%) · Child seat limits belt inspection (1.81%) · Tyre slightly damaged or cracking (1.61%) · Tyre has a shallow cut (1.48%)
