Top failures
Engine warning light inoperative or lit 2.04%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Tyre ply or cords exposed 1.57%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre cut reaching ply or cords 1.04%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Suspension ball joint excessively worn 1%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Tyre bulge from structural failure 0.73%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Rigid brake pipe excessively corroded 0.64%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Common advisories
Tyre worn close to legal limit (8.68%) · Brake pipes corroded and greasy (3.94%) · Tyre slightly damaged or cracking (3.56%) · Suspension ball joint slight play (2.86%) · Brake pads wearing thin (2.46%) · Brake disc pitted or scored (1.93%)
