Top failures
CV joint boot split or insecure 6.64%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Coil spring fractured or broken 6.21%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Suspension ball joint excessively worn 4.58%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Windscreen washer fluid insufficient 4.41%
Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.
Stop lamp not working 3.98%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Rigid brake pipe excessively corroded 3.34%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Common advisories
Brake pipes corroded and greasy (16.92%) · Tyre worn close to legal limit (14.8%) · Brake disc pitted or scored (12.48%) · Tyre slightly damaged or cracking (9.76%) · Brake pads wearing thin (7.14%) · Coil spring showing some corrosion (4.88%)
