Vauxhall Insignia (2021)
2021 Vauxhall Insignia
CarHunch analysed 299 real MOT records for the 2021 Vauxhall Insignia. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Vauxhall Insignia is a solid performer, with an 87.8% first-time pass rate that sits well above the UK average of 80%—suggesting owners are maintaining these cars properly. The 12.4% rate of dangerous defects is manageable and below the threshold that would ring alarm bells, so safety isn't a major concern for this cohort.
At 46,900 miles average, these cars are running relatively light for their age, which helps explain why they're seeing only 0.36 failures per vehicle on test. The 2.2 advisories per car indicate minor wear items cropping up (likely suspension, lighting, or brake wear), so budget for routine servicing and consumables, but don't expect major structural problems—a straightforward buy if you find one with full service history.
What to check before buying a 2021 Vauxhall Insignia
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.
