Polaris Unknown (2014)
2014 Polaris Unknown
CarHunch analysed 730 real MOT records for the 2014 Polaris Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2014 Polaris is an exceptionally poor performer: only 6.6% pass first time, compared to the UK average of 80%, meaning roughly 93 out of every 100 fail their MOT on the first attempt. Diesel variants are particularly problematic at 3.3% pass rate versus petrol's 10.2%, though both are dire. The good news is dangerous defects are rare (1.1% of vehicles), so failures tend to be fixable rather than safety-critical.
The median mileage of 9,600 is extremely low for a 10-year-old vehicle, suggesting most of these are either lightly used or very new to the fleet—yet they're still failing at catastrophic rates, which points to design or manufacturing issues rather than wear. With an average of 0.06 failures and 0.3 advisories per vehicle, the problem isn't severity per failure; it's the sheer number of different things going wrong. If you're considering this model, budget heavily for remedial work and get a full pre-purchase inspection by someone familiar with Polaris quirks, because the statistics suggest ownership will be expensive.
What to check before buying a 2014 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.
