Every Kia Stonic model year
Pass rates fall as cars age, so the only fair comparison for a 2020 car is other cars of the same age. The full run for the Kia Stonic:

What a 6-year-old car fails on
A 2020 car is 6 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:
- Lights and electrical: 10.36% of all cars tested
- Suspension: 8.65% of all cars tested
- Tyres: 6.23% of all cars tested
- Brakes: 6.1% of all cars tested
- Visibility: wipers, washers, glass: 4.65% of all cars tested
- Body, chassis and structure: 3.18% of all cars tested
That is low mileage, which usually means light urban use. Short journeys are harder on batteries, brakes and exhausts than motorway miles, so do not assume low miles means low wear. On a 2020 Kia Stonic the average at test was 24,808 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.
2020 is the strongest year on record for this model at 93.1%, ahead of every other year we hold data for.
