Reliability & safety Rating

4.0 out of 5

The Stonic is a completely new model but it borrows some of the tried-and-tested parts from elsewhere in the Kia and Hyundai ranges. This proved to be a good move, as the Kia Stonic scored highly in our 2020 Driver Power owner satisfaction survey. The news isn’t quite so good on the safety front, as Euro NCAP gives a different score to cars with and without the safety pack.

Kia Stonic reliability

The Stonic finished 27th out of the top 75 cars featured in our 2020 Driver Power survey, which is very impressive and higher than many of its rivals. Just 8.8% of buyers reported a fault in the first year of ownership, and respondents raved about the infotainment system, the amount of kit on board and low running costs.

The seven-year/100,000-mile warranty is undoubtedly a big selling point for Kia’s cars and while it offers fantastic peace of mind for owners foreseeing problems, it also demonstrates how confident Kia is in its products.


The Kia Stonic has been given two ratings by Euro NCAP, and cars with the optional safety pack get the full five stars. Without the pack, the car only received a three-star rating, which may be enough to put some buyers off, as most rivals have five-star scores.

The Stonic comes with six airbags, ISOFIX points for rear seats, hill-start assistance and stability control as standard. Only the ‘3’ and ‘4’ trims come with auto emergency braking and lane-keeping assist - these are standard on most new cars.
