Average for cars of the same age and mileage
Top failures
Wiper blade not clearing windscreen 4.19%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Windscreen washer fluid insufficient 1.48%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Anti-roll bar linkage dust cover unsealed 1.18%
A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.
Brake pads worn below 1.5mm 1.03%
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 0.89%
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 0.84%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Common advisories
Tyre worn close to legal limit (8.13%) · Brake disc pitted or scored (6.7%) · Brake pads wearing thin (4.09%) · Suspension ball joint slight play (2.56%) · Child seat limits belt inspection (1.58%) · Brake discs showing some wear (1.53%)
