Renault Koleos GT Line Blue DCI 4x4cvt (2020)
2020 Renault Koleos GT Line Blue DCI 4x4cvt
CarHunch analysed 181 real MOT records for the 2020 Renault Koleos GT Line Blue DCI 4x4cvt. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 Koleos is a strong performer, with a 90.8% first-time pass rate well above the UK average of 80%, and dangerous defects recorded in just 13.8% of vehicles—a reassuring figure that keeps it out of the high-risk zone. The diesel engine shows solid reliability characteristics with minimal failure issues averaging only 0.41 per vehicle.
These cars are running at a sensible 31,187 miles median for their age, which supports the strong pass rate and suggests owners are maintaining them reasonably well. The 3.3 advisories per vehicle point to minor wear items rather than structural problems, so budget for routine maintenance but don't expect major surprises; have any advisory items checked by a trusted mechanic before purchase to avoid inheriting someone else's deferred work.
What to check before buying a 2020 Renault Koleos GT Line Blue DCI 4x4cvt
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.
