2021 Hyundai I30 Premium MHEV T Gdi

CarHunch analysed 115 real MOT records for the 2021 Hyundai I30 Premium MHEV T Gdi. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2021 Hyundai i30 Premium MHEV T-GDI passes its MOT first time in 85.5% of cases, which is a solid 5.5 percentage points above the UK average of 80%—a genuinely reassuring sign for a car just entering its fourth year on the road. The dangerous defect rate of 13% is well within acceptable bounds, so structural or safety issues aren't a red flag here.

At a median mileage of 22,150 miles for a 2021 model, these cars are running light, which partly explains the strong pass rate. The average vehicle picks up just 0.44 failures and 2.2 advisories per test, suggesting routine wear rather than systemic problems—if you're buying one, get a pre-purchase inspection focused on the hybrid electric components and transmission, since those are where the costs bite if they go wrong.

What to check before buying a 2021 Hyundai I30 Premium MHEV 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.
