Average for cars of the same age and mileage
Top failures
Position lamp not working 3.28%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
CV joint boot split or insecure 3.21%
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
Stop lamp not working 2.99%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Rigid brake pipe excessively corroded 2.84%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Shock absorber serious fluid leak 2.46%
A shock absorber leaking heavily has likely lost its damping, so the car will handle and brake less safely.
Parking brake efficiency below minimum 2.01%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Common advisories
Engine oil leak, not excessive (21.64%) · Brake pipes corroded and greasy (16.27%) · Tyre worn close to legal limit (14.03%) · Shock absorber light oil misting (7.09%) · Brake disc pitted or scored (6.64%) · Suspension arm pin/bush showing wear (5.82%)
