Should I check the MOT history before buying a 2021 Vauxhall Insignia?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Vauxhall Insignia?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Vauxhall Insignia?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2021 Vauxhall Insignia reliable?

Based on MOT data from 299 vehicles, the 2021 Vauxhall Insignia has a first-time MOT pass rate of 89.1%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

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.

We have limited data for the 2021 Vauxhall Insignia — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
