No MOT history yet — it's too new
UK cars don't need their first MOT until they're 3 years old, so there's no test history for the 2023 Kia Stonic GT Line yet. We'll have real reliability data as they start coming through for their first tests.

The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.
The 2023 Kia Stonic GT-Line has not yet accumulated enough MOT test data in the DVLA light-vehicle database to provide reliable pass rates or defect statistics—these vehicles are too new, and many have not yet reached their first test. What we do know is that the median mileage sits at just 7,024 miles, confirming these are barely-run-in cars still within their warranty period, which is why the absence of failures and advisories tells us nothing meaningful about long-term reliability.
If you're considering buying one of these, focus instead on Kia's manufacturer reputation for the Stonic nameplate and the five-year warranty that comes with new Kia vehicles. Once these 2023 models accumulate two to three years of real-world use and pass through their MOTs, the actual reliability picture will become clear—check back then for genuine MOT-based insight, or speak to Kia dealers about build quality and common ownership experiences with the GT-Line trim.
We have 389 2023 Kia Stonic GT Line vehicles on record but don't have enough MOT test data yet to show reliable statistics — as a 2023 model, most vehicles won't have reached their first MOT test date.
