Of every 100 Kia Stonics tested at age 5, about 14 failed the MOT first time; at age 7, about 15 (rough estimate). These are one-year rates for different cars tested in the same year, not a fleet followed over time (2024).

In the Netherlands, 26.8% of Kia Stonics failed their periodic roadworthiness inspection, against 50.8% for all cars there (2024 by country, n = 5,188 inspections).
Inspections abroad point the same way: in Finland and the Netherlands the Kia Stonic also fails less often than the national average.

How the MOT Risk Index and every figure on this page are calculated: methodology.
What is wrong on this page? One tap sends the category only, no text and nothing about you.
88.0% of first attempts passed in 2024 (26,811 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.
Other sites may count retests or all attempts. This page uses 26,811 primary tests: 12.03% failed first time and 91.2% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 81.3 is shown separately.
