Average for cars of the same age and mileage
Top failures
Parking brake efficiency below minimum 5.63%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Airbag warning lamp shows fault 5.35%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Coil spring fractured or broken 2.54%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Suspension mounting area seriously corroded 2.45%
Corrosion near suspension mountings can seriously weaken the body structure, so an expert inspection is needed.
Tyre tread below 1.6mm 2.36%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Rigid brake pipe excessively corroded 2.36%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Common advisories
Brake pipes corroded and greasy (15.61%) · Brake disc pitted or scored (12.61%) · Tyre worn close to legal limit (11.98%) · Suspension arm showing corrosion (8.62%) · Sub-frame showing corrosion (6.62%) · Tyre slightly damaged or cracking (6.17%)
