5/5 Overall
NHTSA 5-Star Safety Rating
The dominant complaint pattern for the 2020 Hyundai Kona centers heavily on the engine. Owners most often describe the engine shutting off unexpectedly while slowing for stops or traffic signals, requiring a shift to park and a manual restart before the vehicle will move again. Many also report the check engine light illuminating, sometimes accompanied by flashing warning lights and occasional oil light activation. Clicking or grinding noises from the engine show up across several reports as well. The electrical system draws the second-highest complaint volume, with owners describing issues ranging from door latch actuator noise to broader electrical faults. The powertrain category includes a handful of reports about transfer case seal leaks. A small number of isolated reports describe more dramatic events, but the recurring theme owners consistently raise is unexpected engine shutdown at low speeds or during deceleration.

By System
The 2020 Hyundai Kona has 6 recalls, the most serious affecting Electric models: the high-voltage battery can short-circuit internally and catch fire, and the electronic brake system can lose braking power significantly, extending stopping distances.
On the non-electric side, vehicles with the 2.0L engine face two risks: the engine can stall unexpectedly, and oil can leak onto hot exhaust components and ignite. Two recalls address the same labeling issue, where the certification label lists an incorrect gross axle weight rating. If an owner relies on that figure to load the vehicle, the Kona can be overloaded, leading to poor handling or a tire failure.
