My wife was pulling into a parking place at Home Depot when the car suddenly accelerated, jumped the curb & hit a tree on the sidewalk. It did significant damage to the front bumper of the car but the airbags did not deploy & my wife was not hurt. I am guessing that it will be several thousand dollars to repair.

While driving approximately 70 mph on I-10 in Louisiana late at night, my 2020 Hyundai Kona EV displayed a “Check EV System” warning while I was on the highway. There were no safe areas or emergency shoulders available to pull over, so I continued driving toward the nearest exit. Approximately 15 minutes after the warning appeared, as I attempted to exit the highway, the vehicle suddenly lost power and rapidly slowed. The vehicle came to a complete stop and could not accelerate, move forward, or reverse. This created a serious safety risk because the vehicle lost propulsion while traveling at highway speed. The vehicle had approximately 62,000 miles at the time of the incident. The vehicle was towed to Giles Hyundai where the dealership diagnosed an internal temperature sensor and resolver failure. Because these components are integrated into the drive system, the dealership replaced the entire traction motor assembly. The repair cost was approximately $9,000. The sudden loss of propulsion at highway speed created a dangerous situation for both the driver and surrounding traffic.

This has happened about 15 times since I bought my Hyundai Kona EV Ultimate new in February 2021: When a car in front of me slows very quickly, occasionally my car tries to help me too much. I have been in complete control of the situations, but my car beeps it's warning, adds it's efforts and the brakes lock up with tires squealing, and we stop with plenty of space in between myself and the car in front of me. This usually happens in freeway traffic. It is terrifying and I always immediately look in my rearview mirror to see if I'm going to get rear-ended. I haven't been hit yet, though I have been flipped off a few times. One of these days, people will be hurt, along with the damages to the cars. The first time it happened was only about 2 weeks after the purchase. I had my 5-year old twin granddaughters in their car seats. Just as described above, the brakes locked up and it really scared them (me too!). I took it back to the salesman I bought it from at Stevens Creek Hyundai and he said it was just a setting with the response time, so he changed it. But it kept happening intermittently. I brought into the Future Hyundai of Concord dealer and they test drove it, could not replicate it, and after checking with their computers, said that the "system is working as designed". Frustrated that I wasn't being heard, I contacted Hyundai Consumer Affairs. They supported me and I got a case number and another appointment at a different dealer, Dublin Hyundai. This time, I went on the test drive and the technician was able to replicate the situation. At first he said it was a setting, but I said that I didn't care what the setting was, this should never happen. It is very dangerous. He agreed and said he would need to contact "Techline" the next day. But when I tried to find out any information about this conversation, I got only silence. Then I got a message that I could come pick up my car and that "the system is working as designed". Help!

Is 27 complaints a lot? They were filed between 2020 and 2026, roughly 4 a year, which is fewer than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2020 has 27 complaints on file, fewer than the 2019 (54) and more than the 2021 (26). Of the 5 model years of the Hyundai Kona Electric we cover, the 2019 has the most (54). Older model years have had longer to collect complaints.
