Top failures
Suspension ball joint excessively worn 3.97%
A worn ball joint can fail and cause loss of steering control, so it must be replaced promptly.
Suspension mounting area seriously corroded 3.61%
Corrosion near suspension mountings can seriously weaken the body structure, so an expert inspection is needed.
Stop lamp not working 3.47%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Rigid brake pipe excessively corroded 3.14%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Position lamp not working 3.07%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Parking brake efficiency below minimum 2.81%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Common advisories
Brake pipes corroded and greasy (21.61%) · Engine oil leak, not excessive (15.26%) · Tyre worn close to legal limit (11.79%) · Suspension arm pin/bush showing wear (6.95%) · Brake disc pitted or scored (6.81%) · Tyre slightly damaged or cracking (6.68%)
