2021 Kia Niro 2 PHEV S A
CarHunch analysed 708 real MOT records for the 2021 Kia Niro 2 PHEV S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Kia Niro 2 PHEV is a reliably built car, passing its MOT first time in 92.5% of cases—well above the UK average of 80%—and only 7.3% of vehicles have ever recorded a dangerous defect, which is reassuringly low. Petrol-hybrid drivetrains on this generation appear to suit the Niro's engineering well, keeping major failures rare.
At 40,576 miles median for a three-year-old vehicle, these cars are running at a typical pace with minimal failure history (0.29 per car on average). The 1.7 advisories per vehicle suggest minor wear items are cropping up as expected, so budget for routine maintenance but don't expect expensive structural surprises—get a pre-purchase inspection focused on the hybrid battery condition and charging system to confirm the PHEV-specific components are sound.
What to check before buying a 2021 Kia Niro 2 PHEV S A
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.
