What fails its inspection
Great Britain's MOT record for the 2020 3.0 hybrid. 25 of 233 tests failed, 11%.
Better than 23% of 2020 cars. The typical one fails 8%, across 906 models with enough tests behind them to say.
| Where | Share of failures | Failed tests |
|---|---|---|
| Tyres and wheels | 88% | 22 |
| Brakes | 8% | 2 |
| Lights and electrics | 8% | 2 |
| Plates and identity | 8% | 2 |

The defects inspectors cite
- A tyre seriously damaged
- Tyre tread depth not in accordance with the requirements
- A tyre cords visible or damaged
- A tyre has a lump, bulge or tear caused by separation or partial failure of its structure. This includes any lifting of the tread rubber
- Number plate does not conform to the specified requirements
- A suspension pin, bush or joint excessively worn
Where it stands out against its peers
- Tyres and wheels: failed more often than 94% of 2020 cars — 88% of its 25 failed tests, where an ordinary 2020 car has 55%.
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.
