Average for cars of the same age and mileage
Top failures
Headlamp aim set too low 2.37%
Headlamps aimed too low light the road poorly and reduce the driver's view ahead, especially at night.
Stop lamp not working 1.82%
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
Tyre ply or cords exposed 1.7%
Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.
Tyre cut reaching ply or cords 1.54%
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 1.2%
Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.
Tyre pressure monitoring system faulty 1.13%
A faulty tyre pressure monitor cannot warn about low tyre pressure, so check tyres manually and have the fault diagnosed.
Common advisories
Tyre worn close to legal limit (11.13%) · Tyre slightly damaged or cracking (7.14%) · Brake disc pitted or scored (6.34%) · Brake pads wearing thin (4.91%) · Nail in tyre, monitor (1.99%) · Tyre worn close to legal limit (1.74%)
