Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 1.31%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Brake pads worn below 1.5mm 0.78%
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 0.7%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Headlamp aim set too low 0.61%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Tyre bulge from structural failure 0.52%
A bulge means the tyre's structure has failed and it could burst suddenly, so it must be replaced at once.
Engine warning light inoperative or lit 0.52%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Common advisories
Tyre worn close to legal limit (5.32%) · Brake pads wearing thin (3.23%) · Tyre slightly damaged or cracking (2.01%) · Track rod ball joint slight play (1.48%) · Tyre has a shallow cut (1.22%) · Brake disc pitted or scored (0.96%)
