Vauxhall Insignia (2012)
2012 Vauxhall Insignia
CarHunch analysed 30,237 real MOT records for the 2012 Vauxhall Insignia. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2012 Vauxhall Insignia passes its MOT slightly less often than the UK average, with a first-time pass rate of 78.6% versus 80%, which is a marginal concern—but the real warning sign is that nearly 47% of these vehicles have recorded a dangerous defect at some point, well above what you'd expect and a serious buyer consideration. Diesel and petrol versions perform almost identically (78.5% and 79.5% respectively), so fuel type isn't a differentiator here.
At 86,400 miles median mileage, these cars are showing their age, and they're racking up an average of 2.78 failures per test, suggesting wear is catching up with them. The high advisory count of 16.3 per vehicle points to numerous minor issues accumulating—worn suspension, tired trim, and general deterioration—so budget for steady maintenance if you're buying one. Before purchase, get a full pre-buy inspection with particular attention to suspension, brakes, and steering components, as these defects cluster heavily on this model.
What to check before buying a 2012 Vauxhall Insignia

- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
