2021 Kia Sportage 3 CRDI Isg MHEV

CarHunch analysed 284 real MOT records for the 2021 Kia Sportage 3 CRDI Isg MHEV. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2021 Kia Sportage 3 CRDi ISG MHEV is a strong performer on the MOT test, with an 89.1% first-time pass rate that sits well above the UK average of 80%, and only 10.6% of vehicles have ever recorded a dangerous defect—suggesting this is a fundamentally sound vehicle. The hybrid-electric powertrain shows no reliability weak spot, maintaining that same 89% pass rate across the cohort.

These cars are running light for their age at an average of 36,031 miles, which helps explain the strong test results, though even accounting for lower mileage the 0.32 average failures per vehicle is genuinely impressive. The 2.1 advisories per test point to minor wear items rather than systemic problems—if you're considering one, check the service history and have a pre-purchase inspection focus on suspension and brake condition, as these typically account for the small advisory issues this model sees.

What to check before buying a 2021 Kia Sportage 3 CRDI Isg MHEV

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.
