Top failures
Coil spring fractured or broken 4.13%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Suspension ball joint excessively worn 3.75%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Rigid brake pipe excessively corroded 3.02%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Tyre tread below 1.6mm 2.73%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Parking brake efficiency below minimum 1.83%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Tyre ply or cords exposed 1.76%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Common advisories
Brake pipes corroded and greasy (16.61%) · Tyre worn close to legal limit (15.72%) · Brake disc pitted or scored (6.56%) · Brake pads wearing thin (6.5%) · Engine oil leak, not excessive (5.9%) · Suspension arm pin/bush showing wear (5.07%)
