Top failures
Coil spring fractured or broken 3.31%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Brake pads worn below 1.5mm 2.64%
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 1.72%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Wiper blade not clearing windscreen 1.43%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Suspension ball joint excessively worn 1.42%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Position lamp not working 1.31%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Common advisories
Tyre worn close to legal limit (14.02%) · Brake pads wearing thin (10.93%) · Brake disc pitted or scored (9.46%) · Tyre slightly damaged or cracking (7.16%) · Suspension arm pin/bush showing wear (6.96%) · Brake pipes corroded and greasy (4.44%)
