Selected complaints filed with NHTSA by 2022 Hyundai Kona owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2022 Hyundai Kona. The contact stated while the vehicle was parked, he noticed while starting the vehicle and switching the headlights from automatic to manual, that the headlights failed to operate as needed. The contact stated that when the headlight switch was placed in the OFF position, the headlights would activate. The contact stated that the switch was working in reverse order. Additionally, the headlights operated properly while using the auto-headlights feature activated. The contact stated that while shifting from Reverse to Drive, the sensor failed to recognize that the vehicle was in Drive. The Reverse audible beep would activate for several seconds. There was no warning light illuminated. The contact called the local dealer but was not able to schedule an immediate appointment for the vehicle to be diagnosed. The vehicle was not diagnosed or repaired. …

The contact owns a 2022 Hyundai Kona. The contact stated that the vehicle stalled while at a complete stop and would restart independently while shifting into park(P). There was no warning light illuminated. Additionally, the contact stated that while driving 65 MPH, a chime sounded, and the message "Think About Taking a Rest" was displayed. The dealer was notified of the failure via email. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 19,842.

When I first brought the car for its first service appointment (6 months after purchase), I informed the service dept at the dealership that the car seemed to accelerate itself when I was driving. They said they hit a reset button and that I shouldn't have any more problems. What I found was that the car then drove sluggishly but it did not accelerate anymore. Recently however (2.5 years into the purchase), the car started "sliding" when I hit the break pad. I took the car in again for service a few months ahead of time and they said that my car mat was wedged under the break pad and that was what was causing the car to slide when I hit the break. The car slid but also accelerated by about 5 miles, however I was able to quickly break and stop it without incident. …

I had the radiator replaced by the Ourisman Hyundai Laurel dealership on 10/1/25. Radiator replacement was under warranty. On 10/4/25car overheated while driving. I pulled the car over and called for a tow truck. Car was leaking lots of coolant. Brought it to service center at Ourisman Hyundai Laurel, they stated "the hose to the thermostat was not all the way on. Put hose on correctly no more leaking." On 10/15/25 multiple lights came on the dashboard including the master warning light. Took car to Ourisman Hyundai Laurel again; received the car back, dealership stated " TECH COULD NOT DUPLICATE THE LIGHTS POPPING ON DASHBOARD. UPON FURTHER DIAGNOSIS TECH FOUND THAT THERE WAS A CONNECTOR NOT GETTING THE PROPER CONTACT TO COIL NUMBER 1 TECH RECONNECTED THE CONNECTOR AND TEST DROVE THE VEHICLE FOR 5 MILES. …

COMPONENT/SYSTEM: Air Conditioning (HVAC) / Climate Control System and closed-loop refrigerant lines. The vehicle and all climate control components are available for immediate inspection. SAFETY RISK: Total loss of cooling in peak summer heat (90 F-95 F+) causes cabin temperatures to rapidly exceed 110 F. This sudden heat trapped in the vehicle caused me (the driver) acute heat exhaustion, culminating in a medical fainting episode. The vehicle regularly transports my newborn baby and toddler, subjecting them to severe heatstroke risks. Additionally, an ongoing 4-year chemical refrigerant leak inside an enclosed EV cabin creates an active toxic inhalation hazard for all passengers. DEALER CONFIRMATION: Yes. The failure has been repeatedly confirmed and documented by authorized Hyundai dealerships, including Paramus Hyundai, Garvey Hyundai, and Liberty Hyundai. …

Car will stop running and not start back up when stopped at a light or stop sign sometimes. I have started driving with the auto start stop off because I will be stuck at a light or stop sign because it will power off but not come back on again. This has occurred several times. The dealership told me there was no issue 11/22/24 but were willing to sell me another battery if I wanted to just replace the battery. The battery would test fine and then not and then fine again. I did price battery's and they tested my battery at auto zone when pricing them and it tested fine with them also. They did not feel like it was a battery issue. I don't either now since it stays on no problem when I turn off the auto start stop. There is something honestly wrong because if I leave that feature on, it will power off and sometimes stay off. …

I have had my horn replaced three separate times at my local Hyundai dealership. It recently passed the NC vehicle inspection, but the horn failed the third time sometime after that inspection in Feb-2025. I have never had a horn EVER fail on ANY car I have owned for the past 50 years. A horn is a critical safety necessity and it is expected to work - especially in times of emergency. I was almost run off the highway, once by a semi-trailer and each time I discovered my horn had failed - it was due to my needing to use it to alert pedestrians or other motor vehicles to avoid accidents. The dealer would not reveal WHY this has failed three times except to state that they 'replaced the horn'. The dealer is the only one to have attempted an examination, diagnosis and supposed repair for this problem. …

As I was backing out of my driveway, I noticed my camera started flashing a green screen and a message appeared intermittently with the flashing green screen saying 'no camera signal try again later. This lasted the entire time I was backing up including once I shifted into drive then it disappeared. I feel that this is a safety risk to others who may be walking or driving by me if I am unable to use the camera. Clearly I don't rely completely on the back up camera as I still tend to look at my surroundings as I back up. I am not even certain if someone was behind me if the warning would even work when the camera is acting up. I have not reported the problem to the dealer yet but I will first thing in the morning. The vehicle has not been inspected yet. The warning messages are described in the first paragraph. Today is first time this has happened. …

Randomly the check engine light turns on and the car begins to violently shake. This is the second day this already happened and only happened while on the highway. The car is only 3 weeks old with just over 1000 miles on it. After pulling over on the side of the road and turning the car off and on, the problem disappeared and the check engine light turns off. The vehicle does not acknowledge that there was an issue. After doing some research, it seems to be consistent with a common issue with Hyundai vehicles having defective ignition coils. Common issue in multiple Konas, Elantras and other Hyundai vehicle The danger of the control of the car on the highway when this issue occurs at random is sufficient enough to ensure that all these vehicles are recalled to get the problem fixed.

December 2025: Yet ANOTHER horn failure. Pressed the vehicle's horn to alert another driver that they were drifting into my lane on the highway, and it FAILED to produce the loud sound that it is SUPPOSED TO make. It needed to be replaced again for the FOURTH time. Part 96611-J9500 was replaced-AGAIN. This is a continued safety issue that Hyundai has neglected to address and fix. Spontaneous horn failure is a HAZARD. The horn is there to warn others of possible danger.
