2011 Vauxhall Insignia Exclusiv 128cdti

CarHunch analysed 282 real MOT records for the 2011 Vauxhall Insignia Exclusiv 128cdti. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2011 Vauxhall Insignia diesel is a reliability concern: it fails its MOT on first attempt in 62.5% of cases, significantly below the UK average of 80%, yet it has never recorded a dangerous defect across the 282 vehicles analysed. The diesel variant shows consistent weakness, with a 62.3% pass rate, so fuel type isn't the issue here.

At 105,000 miles median, these cars are mid-life and showing the strain through an average of 0.63 failures per vehicle, though the complete absence of advisories suggests problems tend to be material faults rather than wear items. If you're considering this model, budget for a pre-purchase inspection to identify common failure patterns before committing—the MOT track record indicates this isn't a "fix and forget" proposition.

What to check before buying a 2011 Vauxhall Insignia Exclusiv 128cdti

Practical pre-purchase checks for this age and model.

  • 📋 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.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
