2021 Hyundai I30 N T Gdi

CarHunch analysed 132 real MOT records for the 2021 Hyundai I30 N T Gdi. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2021 Hyundai i30 N T-GDI passes its MOT on the first attempt 88% of the time, meaningfully better than the UK average of 80%, and only 9.8% of these cars have ever recorded a dangerous defect—well below the concern threshold. This is a genuinely reliable hot hatch for its age and spec.

At 27,556 miles median, these cars are running light for three-year-olds, which partly explains the strong pass rate, but they're still averaging just 0.2 failures per test and 1.3 advisories, suggesting the i30 N is built to last. Before buying, grab the full MOT history to check what those advisories typically are—suspension and brake wear are normal on performance models—but this cohort shows no hidden gremlins.

What to check before buying a 2021 Hyundai I30 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.
