Top failures
Suspension ball joint excessively worn 7.31%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Coil spring fractured or broken 5%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Engine warning light inoperative or lit 4.07%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Tyre tread below 1.6mm 2.89%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Parking brake efficiency below minimum 2.47%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Anti-roll bar linkage dust cover unsealed 2.28%
A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.
Common advisories
Brake pipes corroded and greasy (16.39%) · Tyre worn close to legal limit (15.23%) · Brake disc pitted or scored (8.06%) · Brake pads wearing thin (6.58%) · Suspension arm pin/bush showing wear (6.09%) · Suspension ball joint slight play (5.73%)
