Top failures
Tyre tread below 1.6mm 2.76%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Suspension ball joint excessively worn 1.78%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Coil spring fractured or broken 1.66%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre ply or cords exposed 1.35%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced 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 pads worn below 1.5mm 1.09%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Common advisories
Tyre worn close to legal limit (15.03%) · Brake pads wearing thin (6.32%) · Brake disc pitted or scored (6.16%) · Tyre slightly damaged or cracking (3.13%) · Brake discs showing some wear (3.05%) · Suspension ball joint slight play (2.56%)
