Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 1.79%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 1.32%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Registration plate lamp not working 0.8%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Brake pads worn below 1.5mm 0.63%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Rear fog lamp not working 0.61%
A failed rear fog lamp reduces visibility in fog and leaves you less visible to following traffic, so repair it.
Position lamp not working 0.56%
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 (6.74%) · Brake pads wearing thin (2.58%) · Tyre slightly damaged or cracking (2.14%) · Brake disc pitted or scored (1.81%) · Tyre worn close to legal limit (1.35%) · Brake discs showing some wear (0.79%)
