Average for cars of the same age and mileage
Top failures
Airbag warning lamp shows fault 1.78%
A lit airbag warning means the airbag system may not deploy in a crash, so it needs diagnosing and repairing.
Tyre cut reaching ply or cords 1.26%
A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.
Tyre tread below 1.6mm 1.12%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre ply or cords exposed 0.52%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Number plate does not meet standards 0.37%
The plate does not meet legal specifications, so it must be replaced with a compliant one before the car is driven.
LED or HID headlamp cleaner inoperative 0.37%
Without a working cleaner, dirt can build up on LED or HID lenses and reduce light output, so repair is needed.
Common advisories
Tyre worn close to legal limit (6.54%) · Tyre slightly damaged or cracking (2.53%) · Nail in tyre, monitor (1.93%) · Brake disc pitted or scored (1.78%) · Brake pads wearing thin (1.41%) · Tyre has a shallow cut (1.04%)
