Average for cars of the same age and mileage
Top failures
Parking brake efficiency below minimum 2.74%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Wiper blade not clearing windscreen 2.67%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Track rod end ball joint excessively worn 2.37%
Worn steering ball joints can affect steering control and safety, so repair is needed before the car is driven.
Suspension ball joint excessively worn 2.22%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Engine warning light inoperative or lit 2.17%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Suspension arm corroded and weakened 2.08%
A corroded suspension arm can fail, causing loss of wheel control, so it needs immediate inspection and repair.

Brake disc pitted or scored (12.16%) · Sub-frame showing corrosion (8.75%) · Tyre worn close to legal limit (5.85%) · Tyre slightly damaged or cracking (5.85%) · Suspension ball joint slight play (5.79%) · Track rod ball joint slight play (4.52%)
