2016 Vauxhall Insignia Sri Nav Cdti Eflex Ss

CarHunch analysed 241 real MOT records for the 2016 Vauxhall Insignia Sri Nav Cdti Eflex Ss. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2016 Insignia diesel is notably less reliable than the UK average, with a first-time pass rate of just 63.1% against the national 80%—meaning nearly four in ten fail their MOT. The good news is that dangerous defects are absent from this cohort, so safety isn't the issue; instead, you're looking at consistent wear-related failures that rack up repair costs over time.

At 76,900 miles median mileage, these cars are showing their age without running exceptionally high miles, yet they're averaging 0.54 failures per test, suggesting mechanical fragility rather than hard use. Before buying one, get a pre-purchase inspection from a diesel specialist and budget for regular repairs—this isn't a set-and-forget car.

What to check before buying a 2016 Vauxhall Insignia Sri Nav Cdti Eflex Ss

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.
