Top failures
Tyre tread below 1.6mm 2.52%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Track rod end ball joint excessively worn 2.18%
Worn steering ball joints can affect steering control and safety, so repair is needed before the car is driven.
Brake pads worn below 1.5mm 2%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre pressure monitoring system faulty 1.44%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Tyre cut reaching ply or cords 1.22%
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 1.09%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (12.84%) · Brake pads wearing thin (8.49%) · Brake disc pitted or scored (6.7%) · Tyre slightly damaged or cracking (6.14%) · Brake pipes corroded and greasy (2.87%) · Brake discs showing some wear (2.18%)
