Kia Stonic 2 (2021)
2021 Kia Stonic 2
CarHunch analysed 1,640 real MOT records for the 2021 Kia Stonic 2. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Kia Stonic 2 is a notably reliable first-time passer, with 91.8% of vehicles passing their MOT compared to the UK average of 80%—a solid 11.8 percentage point advantage. Only 5.5% have ever recorded a dangerous defect, which is well below concern threshold and suggests this model's safety systems and critical components are holding up well.
At an average mileage of 25,853 miles for a three-year-old car, these Stonics are running low, which partly explains the strong pass rate but also means you won't find much evidence of how they perform at higher mileages. When failures do occur, they're light (0.23 per vehicle on average) with minor advisories dominating the picture—so if you're buying one, get a pre-purchase inspection focused on those advisory items like worn wipers or minor trim issues, but don't expect major structural or mechanical surprises.
What to check before buying a 2021 Kia Stonic 2
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.
