Equipment Problems of Hyundai Kona - part 1

The horn on my 2023 Hyundai Kona has failed for the third time. This is a dangerous situation. The time before this I barely avoided an accident when a pickup truck was accelerating very fast in reverse from a driveway and didn't see me. Luckily no one was in the oncoming traffic lane and I was able to accelerate into that lane and avoid an accident. But I could not warn him, my horn wasn't working. I can't warn anyone that they're about to drive into my space/lane. It isn't safe. Hyundai needs to permanently fix the horns. I have to test mine everyday when I start my vehicle. I shouldn't have to do that!! do you do that?? do most people have to do that?? do something to help me!!!.

Consider taking a coffee break distracts driver. This issue warrants immediate consideration for a recall. Anytime I drive, this warning keeps going off shortly after going on a windy or pothole filled road (all of PA). Despite driving safely and normally, the problem persists. This occurs regardless of the time of day, weather conditions, or whether I am sitting upright or reclining. The warning randomly activates and deactivates, sometimes without any intervention. Occasionally, I simply allow the warning to sound without taking any action, and it remains active for a few seconds or until it triggers a warning that the system will be turned off, at which point it deactivates. I have attempted various troubleshooting methods, such as keeping my eyes open, adjusting my seating position, wearing and removing my glasses, and tilting them to minimize glare. None of these methods have proven effective in preventing the warning from activating or in making it deactivate. This is a persistent problem. Hyundai dealerships initially informed me that the warning might be an annoyance and their response was to simply refrain from using it. However, if a basic feature like cruise control in a 2024 & 2025 model is rendered unusable due to a design flaw (which this certainly is), it constitutes a clear violation of safety standards and should be addressed through a recall. The incessant alerts are highly disruptive and can be quite frustrating. For instance, driving with an arm in the 12 o’clock position triggers a warning, while wearing polarized sunglasses also results in an alert. The presence of a setting to disable the warning is a welcome feature, but the system’s persistent alerts can be overwhelming. The alerts continue even after taking a break. It is distracting and a safety hazard. Drivers should be able to adjust the sensitivity of the feature or turn it off all together.

The dash will completely go black except for red words signal. * and all warnings are no longer visible, I cannot tell what speed I’m going, or what percentage battery my car is at. I don’t see visible lane or collision warnings. It is very unsafe and I have been to the dealership twice to try and fix it. The issue returned both times.

While I was driving, my car turned off and on again while the car was in motion. I wasn't in an accident, but I did notice the headlights turn off, my dashboard turn off, and a red light appear on the dashboard before the car turned itself back on.

Car went into a limp mode several times, potentially could cause major accident. Towed to dealer who found nothing wrong. Would not give me loaner. I had to sell the Kona in order to have a car, car was bought new had 770 mikes on it. What can I do?.

Recall with car regarding coolant. Last year Hyundai apparently addressed; however, coolant light came on, despite coolant being full. Told by different dealership that with these issues, it needs to be checked and rechecked multiple times; otherwise, issues arise again (as in my case). Want this addressed by dealership. They are charging me a diagnostic fee of $198. Previously, when brought car in for recall work, equipment not always working.

Charging port door will not open. Not sure if it is an issue with acuator, which employee in service dept at dealer said that is common problem. Seems like if this issue with less than 20k, perhaps should also be recall item.

On April 20, 2026 I was pulling into a parking space. I began to break but something went terribly wrong. My car accelerated on it's own, went over the curb and crashed into a building. Three air bags deployed: two on the drivers side of the car (front and side air bag) and one in the back seat behind the driver (the side air bag). I had a [xxx] in the back seat behind the passenger side of the car in a car seat. I was told at the time of the incident that there was not structural damage to the building that was hit. I have asked my insurance company to inspect the car for any malfunctions but they won't. They deem it totaled and say I am at fault because it's my responsibility to control my car. The police arrived but they did not inspect the car either. I have contacted the dealership (parkway Hyundai), but they are of no help either. There were not warning lamps, messages or other symptoms of the problem prior to the failure. However, I did notice recently that when I put my foot on the break to start the car that sometimes the break was very stiff and other times it was not. I thought it strange but thought it was just the way my car was. My insurance is progressive. Claim # xxx information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Basically normal driving the car stalled. It slowed to a stall. I had to restart the car. This has happened a couple to times.

On 3/29/26 my Kona caught fire while parked in the front left side of the engine and burned completely within eight minutes. This is not an electric car. Prior to that I drove the car all day with no incident. It was later in the evening around 5:40 pm. I had driven from my house to a restaurant which is about 6. 8 miles from my house. I parked my car and then my son-in-law noticed that my engine was smoking. My husband went to check to see if it was the radiator, but he noticed that it was fire and we called [xxx] . I know there are no recalls for my car, but I wanted to report it to you. The car only had 44,900 miles on it and was only serviced by west nyack Hyundai. The last service was on 1/19/26. If you have any questions, you can email me at [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My horn is not working again. It was replaced when I initially got the Kona in 2023. It did not work coming out of the dealership. And now again it is back to not working. This is a liability and also a danger to my children.

Much like in the NHTSA bulletin concerning 2024-25 Hyundai's santa fe, santa cruz, and tuscan, my 2024 Hyundai Kona sel has a glitching/flashing infotainment screen. Perhaps it is due to the coaxial shield as in the bulletin for other same model years Hyundais. The screen flickers and the pace at which it flickers and becomes static-y increases, and eventually turns all snowy and sometimes goes blank. A simple pushing of the reset button does not fix the issue. It is distracting, and dangerous, especially if one is relying on the maps for guidance, because there is no way to get the screen to stop the glitching when it occurs. But, it is very random when it happens. Maybe once out of every 10 drives. Seems to be an issue with other drivers with the same 2024 Hyundai Kona.

Hyundai needs to eliminate the “consider taking a coffee break “ alert! its completely distracting, comes in way too frequently, and is loud.

Was driving when the car seemed to lose power and would not accelerate and started shaking. Check engine light came on and got it read, the code indicated a misfire and other errors. There was no one local to fix it as we were out of town. So we replaced the plugs that were indicated and noticed how badly damaged they were. Vehicle started to drive better before stalling out again and replacing the rest of the plugs. Was able to get it home and seemed to be driving normally but then we noticed it has an oil leak now. We have to keep a religious check on the oil because of the amount leaking and the fact the car isn't giving us a low oil warning. We took it to the dealership and they said we needed a new engine and it was just outside the power train warranty. All of this occurred our 78,000-80,000 mile mark. The dealer would not even change the oil before of how bad the leak was. This car was for our teenage daughter and its not safe for anyone to drive. I believe the dealership knew this car had issues, we bought it pre-owned and have only had it 6 months.

Dear Hyundai motor America consumer affairs, I am formally escalating a safety defect involving my 2023 Hyundai Kona, VIN [xxx] , purchased [xxx]. Since the purchase, the vehicle’s horn has repeatedly failed. I have brought the car in for service multiple times, and the issue is thoroughly documented in service records and email correspondence. Despite these efforts, the defect has not been permanently resolved. A non-functioning horn is a serious safety issue. This defect is not isolated; identical horn failures in Hyundai Kona vehicles are widely documented across public internet forums, consumer complaint sites, and owner reports, further underscoring the seriousness of this issue. Given the repeated repair attempts and ongoing safety risk, I am requesting immediate corporate-level review and a clear, permanent resolution. This matter requires prompt attention. [xxx] , service manager, informed me today that my horn was changed/serviced 4 times already. As of today, 2-10-2-26 he is ordering me another horn. Please respond in writing with next steps. Sincerely, [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle trunk doors pops open. This has been happening for several months. We’ve taken it to the dealership. They said that it was not covered and there has been no recall on this, but it’s still happening and it’s very dangerous. It’s happened on the freeway on the back roads at night it doesn’t matter it just when it feels like it wants to open up it beeps loudly and light comes on the dashboard as something is wrong and it will just pop open.

Attempted to sound horn when driver ahead of me crossed lanes at roundabout. Horn did not work. No warning messages appear on dashboard indicating an issue. Inspected the horn fuse in engine compartment and found it to be functional. Vehicle has not yet been taken for repair.

The car was burning through oil every 14 -21days. Car has been jerking and taking a while to accelerate. Went to machine to see what’s going he suggested I go to the dealership because there’s no leaks visible. But added more oil so I wouldn’t go without oil there was nothing available for me to come in right away and before my appointment my car started to speed up out of nowhere then completely slowed down then jerked until I could find a safe space to pull over. Check engine came on and the code was reading a misfire. Got a tune up still reading as a misfire now just stuck at the dealership playing guessing games with what’s wrong with the vehicle.

Liftgate was clicking leaving interior lights on drained battery- had to buy new battery! now liftgate wil not open at all.

I brought vehicle in once for horn not working to dealer. They fixed it. Seven months later in a near traffic incident horn not working. Outside temperatures were below freezing at the time. Following week outside temperatures goes above freezing & horn is working again. It appears horn has an intermittent problem.

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.

The rear left passenger will not open. The dealer thinks it is a faulty door latch actuator ($530 parts and labor). They said this is a common problem and they have a special tool to open the door, but they couldn't get it to work on my car. They think they will damage the interior door panel trying to fix this (approximately an additional $1,000). Warranty expired last year. This is a safety issue because in an emergency a passenger could be trapped in the vehicle or at best delayed in their escape. Also, the dealer said it is a common problem and online forums confirm that across several models and years. Also, it seems to be common for multiple doors to fail.

I was in a rotary and there were two lanes and they both exited to a bridge. I was on the outside lane of the rotary and when exiting the rotary the car from the inside cut me off and I was unable to alert the driver because me horn wasn't working. I blew out 2 tires hitting a curb and needed to be towed. State police arrived on the other side of the bridge. My horn has been replaced by the dealer 3 times now.

Safety system that automatically puts the car in park if a door is opened while in gear failed to apply.

I have gotten a oil change over a month ago and my car is still running low on oil. Sometimes my car would shut off while I’m driving on the road with cars behind me. I have gotten my car oil topped off three different times since getting my oil change. It also makes a fan like noise as well. There’s no leak at all. It’s very bizarre.

The component that failed was the connecting engine rod bearing. The engine is currently in the vehicle located at a Hyundai dealership. The connecting engine rod bearing failure came after 1 or 2 engine miss-fires. The vehicle suffered poor performance, I was unable to start the car and properly accelerate the vehicle. The vehicle has exhibited poor acceleration/ jerk acceleration since purchase. However, this incident occurred immediately during initial startup in a parked position. The vehicle rode roughly upon initial observance of this engine miss fire which led us to deem the engine and car unsafe to use. The vehicle was initially towed to an independent service center where they identified the engine missfire code. The vehicle was then towed to our frequently used independent servicer where they said the problem related to low compression in the engine possibly something internal in the engine. Next we towed the vehicle to our preferred Hyundai dealership. Hyundai confirmed the engine missfires and connecting rod bearing failure. A claim is in process with Hyundai to assess the vehicle further. The check engine light came on when the engine miss-fired initially. An earlier check engine light came on for a missfire earlier in the 2025 and earlier in 2022 and in 2023 which led to a catalytic converter replacement. While not certain, we think that low compression and poor engine performance has plagued the vehicle since purchase. The vehicle drive jerky(poor/delayed acceleration when pressing the gas) and had early catalytic converter issues prior to 50k miles.

I’ve been having issues that align with the safety recall 239 to repair a condition involving the ?electric power control unit ("epcu")?. I seem to be having by a coolant leak, my car is overheating, has stalled and has struggled to start. I started noticing something wasn’t right a couple of weeks ago but wasn’t sure what until more “symptoms” have occurred since and I found the recall information. My air conditioner also will stop blowing cool air when the over heating happens. No lights have come on my dash board alerting me of anything needing to be serviced.

Car keeps stalling no matter what speed you're driving. Took the car to ntb and they said nothing is wrong with it. It continues to happen even in busy highways where someone almost ran into the back of me. Not safe to drive. Concerned as numerous forums suggest this is a problem with 2019-2021 Hyundai Konas.

The dct(dual clutch transmission) has always been an issue since I purchased the vehicle. Anytime I would be going at a slow pace in a drive-thru or traffic on the freeway the car would jolt and shake. I brought my car to a Hyundai dealership in 2021 at 36,000 miles and was told this was normal with the transmissions provided by Hyundai and there was no need to worry. Now, at 72,000 miles I was driving down CA-60 when my car transmission died. The car would not go when I was giving it gas and would make a whirring noise when trying to accelerate across the freeway until I could pull off to the shoulder. It was extremely dangerous and I could've been hit by someone especially a semi-truck as it was sudden and I was in the left hand lane. I've been bringing it to an independent mechanic for years and he always told me to wait until there's a recall as it's a faulty transmission however there has not been a recall for my car yet. The car is now in possession of a Hyundai dealership however I was told since my warranty has passed they are not claiming any responsibility but that their transmission is faulty. There was no warning lamps or messages in the car just the issue of jolting while at slow paces prior to the transmission dying.

The embedded navigation system tends to provide directions getting the vehicle into off road areas that are not designated to be driven. This not only causes damages to the car but also leads to unsafe situations. While driving in the upper peninsula of michigan headed to the kitch-iti-kipi, it took me to tall grass and high voltage towers almost getting me to a ditch. While driving in st. Augustine beach, it almost took me to the ocean. While driving near lubbock texas around a detour due to construction, it almost took me to a cliff.

The issue is the horn. On three different occasions, I've attempted to use the horn and it wasn't working. I've taken it to hallmark Hyundai in flowood and they've repaired and/or replaced the horn on four separate occasions. The new horn is always working when I leave the dealership, but it eventually goes out. Or it goes out for a period of time and then comes back without explanation. My most recent horn outage happened while I was driving on I-55 in jackson ms and an 18 wheeler started shifting in my lane. I wasn't able to notify them with my horn and ended up having to drive on the shoulder to avoid a collision. This is a major safety issue and they haven't taken the time to remedy it.

While slowing down from highway speed during hot weather, the front passenger door suddenly became unlatched and partially opened. A warning alert sounded, and I had to pull the door closed. There were no prior warnings or symptoms, and the dealer has not been able to reproduce the issue.

I was trapped inside the liftgate of my 2023 Hyundai Kona and was unable to operate the emergency release. I had the key fob with me and the car was unlocked, but the trunk would not open from the inside. I tried sliding a standard key and a flat card into the release, but it would not engage. It was not specified that the mechanical key inside the Hyundai fob was required. The release is a small black sliding latch at the bottom of the liftgate with only a car symbol. It is recessed, not easily visible in low light, and does not glow in the dark. I also could not climb over the rear seats because the liftgate hood was sealed, so the fire department had to open the trunk to get me out. Even the operator and the fire department found the instructions difficult to determine. While this may be a rare circumstance, it could have been dangerous. I was able to get out safely, but it would be helpful if the emergency release were redesigned with clearer instructions or made more visible, such as using neon or glow in the dark markings, so that in the future it can be accessed more easily by anyone inside.

The air conditioning system has a drain for condensation. If it gets plugged up, from debris, algae, etc. , it accumulates and sprays it into the passenger cabin. In my auto it sprays considerable water onto the floor boards of both the driver side and passenger side. I encountered such spraying onto my right foot making it slip off the accelerator pad while turning left. While turning right it sprays onto the passenger side. This is an actual spray of water. The dealer reports this is an owner maintenance item. This is not addressed in owner manuals. A search of google issues shows this to be a very big issue. To issues exists. Water onto the accelerator and the brake pedal are safety issues. Wet carpeting causes mold. It is a very bad design.
