What should you check when buying a used Stonic?
The areas above, most common first, and what an MOT tester looks at in each.
1
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 24.2% of Stonic failure items.
2
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 23.5% of Stonic failure items.
3
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 18.5% of Stonic failure items.
4
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 17.9% of Stonic failure items.
5
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 6.7% of Stonic failure items.

What the MOT record doesn't tell you
Knowing Kia Stonic failures cluster around brakes and visibility tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Kia Stonic FAQs
Is the Kia Stonic reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is an 87.8% first-time pass rate for the Kia Stonic across 32,809 tests in 2025, above the 72.3% average for all cars.
Do older Kia Stonic cars fail their MOT more often?
Kia Stonic cars aged 3 to 5 years passed 88.2% of MOT tests in 2025; for examples aged 6 to 10 years that fell to 85%. On an older example, the car's own MOT history tells you more than the model average.
What should I check before buying a used Kia Stonic?
On the car itself, start with the areas it most often fails on: brakes, visibility and tyres. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a Kia Stonic's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
