Top failures
CV joint boot split or insecure 5.13%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Position lamp not working 3.96%
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 3.78%
A major exhaust leak can let poisonous gas into the car and is illegal, so it must be repaired before driving.
Stop lamp not working 2.61%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Wiper blade not clearing windscreen 2.52%
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
Seat belt anchor area weakened 2.52%
Corrosion near a seat belt anchor can weaken the body and make the belt fail, so expert repair is needed.
Common advisories
Brake pipes corroded and greasy (16.46%) · Engine oil leak, not excessive (12.77%) · Wheel bearing slight play (12.14%) · Tyre slightly damaged or cracking (7.19%) · Tyre worn close to legal limit (6.83%) · Coil spring showing some corrosion (5.67%)
