Average for cars of the same age and mileage
Top failures
Position lamp not working 4.32%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Coil spring fractured or broken 3.05%
A broken coil spring can leave the car sitting low or unstable, so it must be replaced before driving.
Stop lamp not working 2.95%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Steering rack gaiter no longer sealed 2.5%
A damaged gaiter lets dirt into the steering rack, causing wear and possibly costly repairs later.
Rigid brake pipe excessively corroded 2.47%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Shock absorber serious fluid leak 1.91%
A shock absorber leaking heavily has likely lost its damping, so the car will handle and brake less safely.
Common advisories
Engine oil leak, not excessive (22.04%) · Tyre worn close to legal limit (15.45%) · Brake pipes corroded and greasy (14.74%) · Shock absorber light oil misting (5.53%) · Brake disc pitted or scored (5.36%) · Suspension arm pin/bush showing wear (4.86%)
