Average for cars of the same age and mileage
Top failures
CV joint boot split or insecure 7.91%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Position lamp not working 6.7%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Coil spring fractured or broken 6.62%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Stop lamp not working 5.96%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Airbag warning lamp shows fault 4.75%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Engine warning light inoperative or lit 3.78%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Common advisories
Tyre worn close to legal limit (21.15%) · Brake disc pitted or scored (12.82%) · Engine oil leak, not excessive (12.15%) · Suspension arm pin/bush showing wear (10.25%) · Sub-frame showing corrosion (8.14%) · Coil spring showing some corrosion (7.44%)
