2021 Kia Rio 3 MHEV
CarHunch analysed 515 real MOT records for the 2021 Kia Rio 3 MHEV. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Kia Rio 3 MHEV is a solid performer on the MOT test, with a 92.7% first-time pass rate that sits well above the UK average of 80%, suggesting these cars are generally well-maintained and reliable. Dangerous defects are uncommon at just 4.9%, so serious safety issues are not a concern for this cohort.
At 20,992 miles median (average 25,761), these vehicles are still relatively young and lightly used, which partly explains the strong pass rate. Owners typically encounter just 0.21 failures and 1.3 advisories per test, indicating straightforward, inexpensive maintenance; before buying one, confirm the service history is complete and check for any pattern of hybrid battery work, as that's where costs could diverge from a petrol equivalent.
What to check before buying a 2021 Kia Rio 3 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.
