Mercedes Unknown (2022)
2022 Mercedes Unknown
CarHunch analysed 187 real MOT records for the 2022 Mercedes Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2022 Mercedes sits bang on the UK average with a 79.6% first-time pass rate, and only 2.1% have ever recorded a dangerous defect—both reassuring signs. The diesel-heavy cohort (163 of 187 vehicles) passes at 78.3%, which is slightly below the Mercedes overall figure, suggesting petrol variants may be marginally more robust.
These cars are running light at 11,842 miles median—typical for their age—and they're failing rarely (0.1 failures per vehicle) with minimal advisory issues (0.3 per vehicle), indicating genuinely trouble-free early ownership. Before committing, verify the exact fuel type and specification, since the unknown designation here masks whether you're buying a petrol or diesel model, and that gap could matter for your maintenance costs.
What to check before buying a 2022 Mercedes Unknown
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.
