Top failures
Wiper blade not clearing windscreen 2.11%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 1.68%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Parking brake efficiency below minimum 1.01%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Tyre cut reaching ply or cords 0.83%
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 0.61%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Service brake efficiency below minimum 0.54%
The brakes are not stopping the car effectively enough, a serious safety risk that needs urgent repair before driving.
