Average for cars of the same age and mileage
Top failures
CV joint boot split or insecure 6.02%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Position lamp not working 4.64%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Exhaust has major gas leak 3.36%
A major exhaust leak can let poisonous gas into the car and is illegal, so it must be repaired before driving.
Wiper blade not clearing windscreen 2.86%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Stop lamp not working 2.47%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Suspension mounting area seriously corroded 2.27%
Corrosion near suspension mountings can seriously weaken the body structure, so an expert inspection is needed.
Common advisories
Brake pipes corroded and greasy (18.46%) · Wheel bearing slight play (13.62%) · Engine oil leak, not excessive (12.64%) · Tyre worn close to legal limit (7.11%) · Exhaust has minor gas leak (6.61%) · Chassis corroded but still rigid (6.42%)
