What this means for buyers
- Worse than average: 40.69% of tests found a failing defect — more than cars of the same age normally show.
- Most common specific failures: a transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc · a spring or spring component fractured or seriously weakened · a rear registration plate lamp or light source missing or inoperative in the case of multiple lamps or light sources.
- 46.4% of diesels fail vs 36.4% of petrols — the diesel versions age notably worse here.
- ≈17 dangerous defects found per 100 tests — a dangerous defect means the car legally cannot be driven away from the test.
- Ask the seller about: A transmission shaft constant velocity joint boot missing or
- Ask the seller about: A spring or spring component fractured or seriously weakened
- Try every light and switch — lamps are a top failure
- Ask the seller about: A steering ball joint with excessive wear or free play

Where they fail most
Every dot is a postcode area — size = how many were tested there, colour = share failing. Raw rates: coastal and rural areas run older fleets and salted roads.

Data details & how to cite
Scope: class-4 vehicles (cars), initial tests only, outcomes pass / fail / fixed-on-the-spot at the station (PRS counts towards the failure rate — the defect was present at arrival). Index = observed initial failures ÷ failures expected for this fleet's exact age profile, ×100; margin of error is a 95% confidence interval. Covers ALL generations together — a 3-year-old and a 15-year-old are very different cars; a generation split is on the roadmap. Dataset release dvsa-2024-v1, frozen baseline.
