Average for cars of the same age and mileage
Top failures
Position lamp not working 0.88%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Headlamp aim set too low 0.78%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Coil spring fractured or broken 0.68%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Wiper blade not clearing windscreen 0.62%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Engine warning light inoperative or lit 0.47%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Tyre cut reaching ply or cords 0.47%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Common advisories
Tyre worn close to legal limit (4.37%) · Brake pads wearing thin (3.54%) · Tyre slightly damaged or cracking (3.38%) · Shock absorber light oil misting (3.33%) · Brake disc pitted or scored (1.4%) · Brake pipes corroded and greasy (1.35%)
