Polaris Unknown (2012)
2012 Polaris Unknown
CarHunch analysed 555 real MOT records for the 2012 Polaris Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2012 Polaris is a serious reliability concern: only 3.3% pass first time against the UK average of 80%, with diesel variants performing even worse at 1.6% pass rate versus petrol at 5.1%. Nearly 1% of vehicles have recorded dangerous defects, which is unusually high and a genuine safety red flag for prospective buyers.
The low average mileage of 6,447 miles suggests these are niche leisure vehicles with sporadic use, yet they still accumulate failures (0.02 per vehicle) and advisories (0.1 per vehicle) at concerning rates. Before purchasing any 2012 Polaris, have an independent inspection specifically focused on safety-critical systems, as the MOT pass data indicates systemic reliability issues regardless of mileage.
What to check before buying a 2012 Polaris 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.
