Top failures
Brake pads worn below 1.5mm 1.22%
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 1.16%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 0.76%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too low 0.52%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre cut reaching ply or cords 0.52%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre bulge from structural failure 0.46%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Common advisories
Tyre worn close to legal limit (8.6%) · Brake pads wearing thin (6.91%) · Brake disc pitted or scored (6.39%) · Tyre slightly damaged or cracking (2.44%) · Tyre has a shallow cut (1.8%) · Child seat limits belt inspection (1.28%)
