Average for cars of the same age and mileage
Top failures
CV joint boot split or insecure 6.48%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Coil spring fractured or broken 4.69%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Airbag warning lamp shows fault 3.72%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Position lamp not working 3.53%
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 3.49%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Stop lamp not working 3.48%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Common advisories
Tyre worn close to legal limit (19.26%) · Brake disc pitted or scored (11.73%) · Engine oil leak, not excessive (9.24%) · Suspension arm pin/bush showing wear (7.57%) · Tyre slightly damaged or cracking (7.39%) · Brake pads wearing thin (6.45%)
