What fails its inspection
Great Britain's MOT record for the 2010 1.6 diesel. 17 of 55 tests failed, 31%.
Better than 7% of 2010 cars. The typical one fails 24%, across 955 models with enough tests behind them to say.
| Where | Share of failures | Failed tests |
|---|---|---|
| Suspension | 65% | 11 |
| Brakes | 53% | 9 |
| Lights and electrics | 47% | 8 |
| Body and structure | 29% | 5 |
| Exhaust and emissions | 18% | 3 |
| Tyres and wheels | 18% | 3 |
The defects inspectors cite
- A spring or spring component fractured or seriously weakened
- A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning
- A suspension pin, bush or joint excessively worn
- A brake lining or pad worn below 1.5mm
- A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc
- Parking brake efficiency below minimum requirement
Where it stands out against its peers
- Suspension: failed more often than 96% of 2010 cars — 65% of its 17 failed tests, where an ordinary 2010 car has 42%.
- Brakes: failed more often than 96% of 2010 cars — 53% of its 17 failed tests, where an ordinary 2010 car has 29%.
- Body and structure: failed more often than 91% of 2010 cars — 29% of its 17 failed tests, where an ordinary 2010 car has 12%.
Same model year only, at least 30 peer cars, zeros included. Every car has a worst part; this shows which, and how far from ordinary it is. A high share means more to check, not a verdict.
NHTSA's investigations are American; no European regulator publishes an equivalent record, so this section has nothing to draw on for a European car. There is no European equivalent of the service-bulletin register either.
