2023 Kia Niro 2 PHEV S A

CarHunch analysed 829 real MOT records for the 2023 Kia Niro 2 PHEV S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2023 Kia Niro 2 PHEV is failing its MOT at an alarming rate: just 11.9% pass first time compared to the UK average of 80%, which is a massive red flag for a car this new. The dangerous defect rate is mercifully low at 0.4%, but the vast majority of these vehicles are returning with failures rather than minor advisories.

With a median mileage of just 34,130 miles for a 2023 model, these cars are still very young yet already struggling through testing—this isn't a high-mileage wear story. The average vehicle has virtually no failures recorded (0.01) but only 0.1 advisories, suggesting the MOT system is catching significant problems rather than gradual deterioration, which points to potential build quality or design issues. If you're considering this model, get a pre-purchase inspection from a Kia specialist and ask the seller specifically what work was needed to pass its last MOT.

What to check before buying a 2023 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.
