Top failures
Coil spring fractured or broken 2.82%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Seat belt retractor defective 2.21%
A defective retractor may not lock or spool properly, so the belt may not restrain you in a crash.
Brake pads worn below 1.5mm 1.61%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Wiper blade not clearing windscreen 1.55%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Seat belt not functioning as intended 1.21%
A seat belt not working properly may fail to protect you in a crash, so it must be repaired or replaced.
Tyre cut reaching ply or cords 1.19%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Common advisories
Tyre slightly damaged or cracking (10.67%) · Tyre worn close to legal limit (10.17%) · Brake pads wearing thin (9.4%) · Brake disc pitted or scored (6.07%) · Brake pipes corroded and greasy (3.91%) · Brake discs showing some wear (2.45%)
