Average for cars of the same age and mileage
Top failures
Stop lamp not working 4.96%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Position lamp not working 3.03%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Wiper blade not clearing windscreen 2.49%
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 2%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Coil spring fractured or broken 1.98%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Headlamp beam pattern obviously incorrect 1.97%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Common advisories
Brake pipes corroded and greasy (13.94%) · Tyre worn close to legal limit (11.9%) · Tyre slightly damaged or cracking (7.94%) · Wheel bearing slight play (7.3%) · Engine oil leak, not excessive (7.09%) · Coil spring showing some corrosion (5.74%)
