About & method Where this comes from. Computed from the DVSA anonymised MOT results for Great Britain, 2025 (42.7 million tests). Failure rates are first-time tests only, excluding retests. Wear items like tyres and pads are shown separately from faults with the car itself.
Fault File is independent and not affiliated with the DVSA. Covers over 340 of the most common cars on UK roads, split by generation where the data allows.
