Average for cars of the same age and mileage
Top failures
Coil spring fractured or broken 5.56%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Suspension ball joint excessively worn 4.3%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Airbag warning lamp shows fault 2.85%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Parking brake efficiency below minimum 1.97%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Rigid brake pipe excessively corroded 1.78%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Tyre tread below 1.6mm 1.69%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Common advisories
Brake pipes corroded and greasy (12.47%) · Tyre worn close to legal limit (11.14%) · Tyre slightly damaged or cracking (6.83%) · Brake disc pitted or scored (5.5%) · Suspension arm pin/bush showing wear (4.88%) · Exhaust mounting defective (3.69%)
