Top failures
CV joint boot split or insecure 5.16%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Suspension ball joint excessively worn 4.95%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Track rod end ball joint excessively worn 2.68%
Worn steering ball joints can affect steering control and safety, so repair is needed before the car is driven.
Coil spring fractured or broken 2.68%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Airbag warning lamp shows fault 2.65%
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.
Common advisories
Brake disc pitted or scored (15.81%) · Engine oil leak, not excessive (13.01%) · Tyre worn close to legal limit (11.27%) · Suspension arm pin/bush showing wear (7.73%) · Wheel bearing slight play (7.46%) · Tyre slightly damaged or cracking (6.16%)
