Better than 73% of 2004 cars. The typical one fails 28%, across 750 models with enough tests behind them to say.
| Where | Share of failures | Failed tests |
|---|---|---|
| Suspension | 47% | 41 |
| Body and structure | 28% | 24 |
| Exhaust and emissions | 26% | 23 |
| Tyres and wheels | 18% | 16 |
| Brakes | 16% | 14 |
| Lights and electrics | 15% | 13 |
The defects inspectors cite
- The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired
- Lambda coefficient outside the default limits or the range specified by the manufacturer
- Exhaust system leaking or insecure
- The strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired
- A tyre seriously damaged
- Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced

When it starts failing
At 80–100k miles this one fails 29% of its inspections, against the 28% an ordinary car of the same age fails.
| Odometer | Failure rate | Rate | Its age | Tests |
|---|---|---|---|---|
| 20–40k miles | 13% | 17% | 55 | |
| 40–60k miles | 23% | 22% | 115 | |
| 60–80k miles | 30% | 25% | 107 | |
| 80–100k miles | 29% | 28% | 55 |
332 British inspections, grouped by the odometer reading recorded at the test.
Half of these have more than 40k miles on them. That is how far people drive this car, not how long it lasts.
