Expert verdict
Steering: 7.6× the national share
Steering accounts for 19.5% of everything recorded on the 2020 Kia Stonic Connect, against 2.6% nationally — 16.9 points above. Tyres are still the single largest share at 24.9%, but at 19.8% nationally that one is ordinary. Ask for the steering to be checked for play with the wheels on the ground, not on a jack.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 90.7% and this one manages 93.9% — 3.2 points ahead of what its age and mileage predict.
- Based on a small sample. 346 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

What fails a 2020 Stonic Connect
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2020 Stonic Connect
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the wipers and washers 2.9% of tests
“wipers blade defective”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
-
Check the suspension joints 1.7% of tests
“track rod end ball joint has excessive play”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
Check the windscreen 1.7% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
