Average for cars of the same age and mileage
Top failures
Parking brake efficiency below minimum 3.69%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Tyre tread below 1.6mm 2.72%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Shock absorber serious fluid leak 2.44%
A shock absorber leaking heavily has likely lost its damping, so the car will handle and brake less safely.
Airbag warning lamp shows fault 2.34%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Windscreen washer fluid insufficient 2.11%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Position lamp not working 2.08%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Common advisories
Tyre worn close to legal limit (16.34%) · Engine oil leak, not excessive (15.07%) · Brake pipes corroded and greasy (12.94%) · Flexible brake hose slightly deteriorated (11.15%) · Suspension arm pin/bush showing wear (8.34%) · Brake disc pitted or scored (7.42%)
