Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 3.15%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre ply or cords exposed 1.46%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre tread below 1.6mm 1.46%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre cut reaching ply or cords 1.45%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Registration plate lamp not working 0.63%
A dark number plate lamp makes the plate hard to read at night, which is illegal and must be fixed.
Windscreen washer fluid insufficient 0.44%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Common advisories
Tyre worn close to legal limit (11.74%) · Tyre slightly damaged or cracking (8.34%) · Brake disc pitted or scored (3.4%) · Tyre has a shallow cut (2.02%) · Child seat limits belt inspection (2%) · Tyre worn close to legal limit (1.99%)
