Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 1.55%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Tyre tread below 1.6mm 0.7%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp aim set too high 0.65%
Headlamps aimed too high can dazzle other drivers, and adjusting them is usually a quick job.
Tyre cut reaching ply or cords 0.49%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Headlamp levelling device inoperative 0.4%
A faulty levelling device means the headlamps may dazzle others or light the road poorly when the car is loaded.
Headlamp aim set too low 0.36%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
