Top failures
Wiper blade not clearing windscreen 4.22%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Dipped beam headlamp not working 2.88%
A failed dipped beam makes it hard to see and be seen at night, so the lamp needs fixing before driving.
Tyre tread below 1.6mm 1.85%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Windscreen washers not working 1.76%
Without working washers the windscreen cannot be cleaned while driving, which is a safety risk in dirty weather.
CV joint boot split or insecure 1.6%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Position lamp not working 1.37%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
