Top failures
Engine warning light inoperative or lit 1.86%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Brake pads worn below 1.5mm 1.5%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre cut reaching ply or cords 0.92%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Stop lamp not working 0.81%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Tyre tread below 1.6mm 0.67%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Diesel engine warning light faulty 0.57%
A lit or non-working engine warning light can hide faults, so diagnosis is needed before buying.
Common advisories
Brake pads wearing thin (7.4%) · Tyre worn close to legal limit (6.52%) · Tyre slightly damaged or cracking (3.25%) · Brake disc pitted or scored (2.61%) · Tyre has a shallow cut (1.96%) · Brake discs showing some wear (1.66%)
