Average for cars of the same age and mileage
Top failures
Diesel engine warning light faulty 2.71%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Coil spring fractured or broken 2.63%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Anti-roll bar linkage pin/bush excessively worn 2.48%
Worn linkage pins or bushes cause knocking and poor handling, and can get worse, so they need replacing.
Position lamp not working 2.44%
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 2.43%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 1.87%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Tyre worn close to legal limit (16.77%) · Suspension arm pin/bush showing wear (11.61%) · Brake disc pitted or scored (8.56%) · Brake pads wearing thin (6.95%) · Anti-roll bar linkage pin/bush worn (6.02%) · Tyre slightly damaged or cracking (4.98%)
