Top failures
Coil spring fractured or broken 9.44%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Tyre tread below 1.6mm 3.74%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Brake pads worn below 1.5mm 3.41%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Registration plate lamp not working 2.13%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Wiper blade not clearing windscreen 1.97%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Dipped beam headlamp not working 1.66%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Common advisories
Tyre worn close to legal limit (18.43%) · Brake pads wearing thin (9.52%) · Suspension arm pin/bush showing wear (5.3%) · Tyre slightly damaged or cracking (5.22%) · Brake disc pitted or scored (4.83%) · Engine oil leak, not excessive (3.39%)
