Average for cars of the same age and mileage
Top failures
Position lamp not working 2.89%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Airbag warning lamp shows fault 2.61%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Wiper blade not clearing windscreen 2.3%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Headlamp beam pattern obviously incorrect 2.27%
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
Stop lamp not working 1.92%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Engine warning light inoperative or lit 1.7%
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 (11.79%) · Brake disc pitted or scored (8.64%) · Sub-frame showing corrosion (6.22%) · Engine oil leak, not excessive (5.93%) · Brake pads wearing thin (4.82%) · Flexible brake hose slightly deteriorated (4.18%)
