Average for cars of the same age and mileage
Top failures
Position lamp not working 6.6%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Engine warning light inoperative or lit 6.09%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Coil spring fractured or broken 4.59%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
CV joint boot split or insecure 4.11%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Suspension arm pin/bush excessively worn 3.53%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Airbag warning lamp shows fault 3.39%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Common advisories
Brake pipes corroded and greasy (16.79%) · Suspension arm pin/bush showing wear (14.69%) · Tyre worn close to legal limit (13.3%) · Brake disc pitted or scored (11.69%) · Coil spring showing some corrosion (8.37%) · Engine oil leak, not excessive (6.57%)
