“The horn stopped working shortly after purchasing the vehicle in July 2021. We have been waiting for an appointment to get it looked at for months with our local Hyundai dealer but they don't have any service appointments. There have been several close calls with other vehicles and pedestrians and it is only a matter of time before something happens.”
NHTSA complaint #11498069, filed 2022-12“There has been a continuous popping noise on the right side of the vehicle near the tire like it’s an axle or something with the suspension. It has been checked and I was told it was normal. The horn will stop working along with the radio and other components in the car. The forward front accident component will say I’ve been in an accident when I have not even been near a vehicle. This has happened on several occasions. I don’t have all specific dates.”
NHTSA complaint #11665015, filed 2025-06“Transmission slip out of park I was at a complete stop in park got out of the car to get my purse an as I pull the hacker it was still locked so I came around and reached in the car to turn the car off an as I attempted to pull the key out the car started roll back drugged me about 150 feet down the inbank.”
NHTSA complaint #11429683, filed 2021-08“I had a flat tire (passenger side right front tire). Triple AAA removed tire and replaced with my spare tire. While driving to the Hyundai dealership, massive clouds of smoke poured out of my exhaust pipe in rear of car. I also had trouble steering the car. The result of using the spare tire burned the transmission fluid (also contained metal shavings). The transmission had to be replaced along with the fluids in my car.”
NHTSA complaint #11421821, filed 2021-06“I had a 2021 Hyundai Kona limited. On Friday 09/13/2024 my engine caught fire and my car was a total loss. Minutes before the fire I noticed some smoke, all of my dash lights came on and the car shut down. Seconds after stopping the vehicle and getting out the whole engine went up in flames. There are recalls active for my make model and year, nothing for my specific vin number but will be reaching out to Hyundai corporate to see if they want to come look at the car, in case it needs to be added to the recall list.”
