Average for cars of the same age and mileage

Top failures

  1. Tyre ply or cords exposed 2.68%

    Exposed ply or cords can let the tyre fail suddenly, so the tyre must be replaced before the car is driven.

  2. Tyre tread below 1.6mm 1.15%

    Tread below 1.6mm is illegal and reduces grip in wet conditions, so the tyre must be replaced.

  3. Windscreen washer fluid insufficient 0.92%

    Washers are not supplying enough liquid, so the windscreen cannot be cleared properly, which is a safety issue.

  4. Wiper blade not clearing windscreen 0.8%

    Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.

  5. Tyre cut reaching ply or cords 0.69%

    A cut reaching the ply or cords weakens the tyre and can cause a burst, so it must be replaced.

  6. Tyre pressure monitoring system faulty 0.46%

    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 (9.41%) · Brake disc pitted or scored (1.68%) · Tyre slightly damaged or cracking (1.41%) · Tyre worn close to legal limit (1.22%) · Nail in tyre, monitor (0.88%) · Shock absorber light oil misting (0.84%)
