Average for cars of the same age and mileage
Top failures
Headlamp aim set too low 4.55%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Brake pads worn below 1.5mm 2.48%
Pads worn below 1.5mm lose stopping power and can damage discs, so replacement is needed before the car is driven.
Tyre tread below 1.6mm 2%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
ABS warning lamp shows a fault 1.97%
A lit ABS warning means the anti-lock system may not work, so wheels could lock during emergency braking.
Tyre pressure monitoring system faulty 1.64%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Airbag warning lamp shows fault 1.42%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Common advisories
Brake disc pitted or scored (15.54%) · Tyre slightly damaged or cracking (13.51%) · Tyre worn close to legal limit (10.93%) · Brake pads wearing thin (6.74%) · Child seat limits belt inspection (2.68%) · Nail in tyre, monitor (2.58%)
