2021 Hyundai I20 N T Gdi

CarHunch analysed 311 real MOT records for the 2021 Hyundai I20 N T Gdi. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2021 Hyundai i20 N T-GDI is a reliably robust first-time passer, with an 89.2% pass rate that sits well above the UK average of 80%, and only 8.4% of vehicles ever registering a dangerous defect—a low concern figure for buyer safety. Its petrol engine maintains that same 89.1% pass rate, showing consistency across the fleet.

With a median mileage of just 25,481 miles for cars now three years old, this cohort is running light, which explains the modest average of 0.28 failures per vehicle and 1.2 advisories per vehicle—both suggesting minimal wear so far. When you come to buy, check the service history carefully and budget for typical wear items like tyres and brake pads, but don't expect major structural or mechanical surprises in the next couple of years.

What to check before buying a 2021 Hyundai I20 N T Gdi

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.
