Average for cars of the same age and mileage
Top failures
Position lamp not working 4.51%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Tyre tread below 1.6mm 2.77%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Headlamp beam pattern obviously incorrect 2.51%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Wiper blade not clearing windscreen 2.17%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Engine warning light inoperative or lit 1.93%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Brake pads worn below 1.5mm 1.88%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Common advisories
Tyre worn close to legal limit (14.97%) · Brake disc pitted or scored (8.6%) · Brake pads wearing thin (8.11%) · Tyre slightly damaged or cracking (5.58%) · Brake pipes corroded and greasy (5.51%) · Exhaust has minor gas leak (4.75%)
