Vauxhall Insig SRI NAV VX RD Cdtieco SS

What fails its inspection

Great Britain's MOT record for the 2013 2.0 diesel. 13 of 67 tests failed, 19%.

Better than 48% of 2013 cars. The typical one fails 19%, across 828 models with enough tests behind them to say.

The defects inspectors cite

• A tyre seriously damaged
• A spring or spring component fractured or seriously weakened
• A brake lining or pad worn below 1.5mm
• A tyre cords visible or damaged
• Any fracture or welding defect on a wheel
• Engine MIL illuminated indicating a malfunction

Where it stands out against its peers

• Tyres and wheels: failed more often than 96% of 2013 cars — 54% of its 13 failed tests, where an ordinary 2013 car has 29%.

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.
