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. This last service was on Friday, August 1st, and on Sunday August 3, the car slid and accelerated again - without the floor mat being wedged under the break. On Monday morning (August 4th) I called Hyundai so many times that I lost count. I was never able to speak with a service employee but I was given an appointment for a week and half later. According to chatgpt, it is a common issue with the 2022 Kona and it should be recalled.
Car stalled while stopped in drive or while in park. Forward collision system error warning. Every yellow warning light illuminated. Car would restart and would shift gears up when accelerating but would not shift back down. Tachometer would not move although engine was revving. Park and turn off car. Open door. Close door. Restart and all lights off and engine runs fine until it stalls again. Repeat process. No accidents. Car at 62000 miles. Very dangerous on highway.
While accelerating onto the highway, the engine backfired and suddenly lost speed, violently shaking.
My Kona sputters when I put it in gear every time. I have purchased gas at several stations so getting bad gas in the tank cannot be an issue. I’ve also had to replace the coil packs twice within 6 months. December 2024 and July 2025.
The contact owns a 2021 Hyundai Kona. The contact stated while driving at undisclosed speeds, the vehicle started accelerating slowly. The contact stated that while driving at an undisclosed speed, the vehicle stalled. There was an abnormal dinging sound coming from the vehicle. There was no warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed and determined that the battery needed to be replaced, and the vehicle was experiencing excessive oil consumption. The mechanic recommended additional testing. The contact declined the additional diagnostic test. The vehicle was not repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 35,000.
The button that sets or changes the speed control broke and no longer provided functionality, requiring replacing the whole right-side steering wheel button control module. This in turn required removing the entire steering wheel, which included removng the driver’s side airbag.
This has happened 3 times and I’ve only owned the car since sept 2023, the first time was Feb 4 2024, then Feb 28th and March 11, 2024, when I am trying to accelerate I push on the gas and the rpm’s will go higher but the car doesn’t gain any speed. So when trying to pass a vehicle I can’t because it will do this and it’s dangerous, I do have a video of this.
Loss of power to speed unable to acceleration had to pull over.
For about a month, the car is pausing for a second or two during acceleration. The car was brought for service to great lakes Hyundai of columbus (ohio) on 12/19/2023. This is diagnosis and remediation that was offered: needs immediate attention 1 of 5 services related requested service [primary]: 10hyz06 - c/s check engine light check and advise: c/s check engine light check and advise check engine light - diagnosis - customer states the car is driving rough when changing gears, does not want to accelerate, has to put the peddle on the floor. [other]: transmission control unit update speak with your service advisor for more information on this recommended service. There were no warnings. I just noticed to the problem, and it was getting worse.
While driving on the highway on an extended trip my cruise control dropped its speed from 71 to 65 without warning. On one occasion it happened while I was in the passing lane with a lot of traffic behind me. It created a very dangerous situation before I could get into the right lane. Another incident was when again I was driving along, no one in front of me, beside me or behind me and the speed dropped once again. Had I been in traffic who knows what would have happened. I have turned the automatic breaking system off because while on a trip I was in the right lane when a car cut me off. The breaks went on and the car went totally out of control! I have filed a complaint with Hyundai and after waiting 8 weeks for a call regarding my case number they refuse to acknowledge that it is a manufacturing issue. I have had the vehicle into the dealer 3 times and they have not been able to replicate it by driving around the area, but have not taken it out on the highway at a higher speed which is when it occurs and when one would use the cruise control. I have only 9,000 miles on the car at this point and no remedy in sight.
Car stopped accelerating on the highway and held me at 40mph. This happened twice. Then before being able to get it in for service while driving the car made a loud bang and came to a rolling stop again on the highway and the transmission control system alarm went off and the car would not move. Had to get towed off the highway and in a rental now. This was a brand new 2023 Hyundai Kona sel limited.
While traveling at 70 mph on the freeway my 2023 Kona with less than 2,000 miles dropped into neutral and lost speed, almost causing a crash. I’m lucky the driver behind me braked in time. The dealer has informed me that the transmission needs to be replaced.
After the recall was corrected, the engine light came on two months later. I noticed the car will not accelerate and now will not start. The engine rumbles on the occasion that it does start.
My car has approximately 14,000 miles on it and was purchased brand new. It still has 1,000 miles to go before the next servicing. Saturday I when driving approximately 40 miles an hour, the engine suddenly cut off and the car stopped in the middle of the road. I was able to start the car and drive for approximately 15 minutes before it slowed to 3mph and shut off again. I called the dealership where I purchased it and explained what happened. Initially they said they had not serviced the car in a year. I let the car sit for a day then checked all the fluids. The coolant level was fine and so was the oil. Monday, it cut off twice on my way to work. I drove to the nearest dealership and left it there. I had to rent a car as no loaners are available. It has been at the dealership for 5 days. They thought they fixed but when they test drove it, the car cut out again. Later that day, I received an email from Hyundai blue link with an automatic dtc notification that a possible condition has been detected with my engine control system.
The cruise control on this 2023 Kona has not worked since the day I purchased it. When the cruise control is engaged it will suddenly decelerate, but the cruise still appears engaged. It sometimes then suddenly reaccelerates. This causes traffic to suddenly back up behind me, and also to be in danger in front of me when it reaccelerates rapidly. I informed the dealer immediately of the issue. They advised there was a 2022 in their shop for the exact same issue at 8,000 miles. They asked me to bring mine in, which I have done now three times. That shop now has 4 Konas with the exact same issue, yet they do not have a fix. The Hyundai forum boards are full of this same complaint. I have contacted Hyundai corporate. They also don’t have a solution, but won’t take back my new vehicle. I have less than 1,000 miles on this Kona - most of that from driving one hour to/from the dealer 3 times. I have been understanding and professional in my dealings with them however, I have run out of patience. I did not get what I paid for and am being asked to put myself/my family in danger driving this vehicle back and forth to this dealer who doesn’t even have a fix.
The car is set at a speed for cruise control. For no reason it loses power, after a while it returns speed as set. At the beginning the doors weren’t working for locking and unlocking by the handle. Seems okay now but I made a video showing the rear camera staying on while driving. Also included, two pictures of maintenance reports with different results.
Vehicle will not go out of 3rd gear when on the interstate. The vehicle will go pass the redline and hit the fuel cut off and will not accelerate. Have to slow the car down and attempt to speed up again. Vehicle has almost been in accident multiple times due to almost being rear ended because can not get the vehicle up to speed.
This is my 2nd report on the same issue. There is another report from me on the first and I will be discussing this with my Hyundai dealer today. On a 250 mile road trip, on the expressway, two separate times, the car suddenly braked hard and the emergency warning flashed on the speedometer. Each time it was about 3-5 seconds. On the second incident, my passenger thinks she noticed it happening in conjunction with a car appearing on my side. She said the side mirror warning lit up at the same time the car started braking. It could just be a coincidence though. Thankfully, neither time did the brakes fully stop the car, but damn, it is very scary when it happens on the expressway and I am very nervous to drive with the feature on.
There are multiple issues with the adaptive cruise control: -when setting the cruise control speed, it can drop 10-15 mph until it kicks in. -when a car pulls in front of you with the adaptive cruise control on, it takes to long to recognize it has to slow down and has to abruptly decrease speed when it finally does. -if the adaptive cruise control does slow down because of a driver in front of you and that driver changes lanes, the adaptive cruise control can again take 10-mph drop until it kicks in. .

It is called a "Smart cruise" and it does not hold the speed. When driving on the interstate and the speed does not hold that would cause a risk of collision by other vehicles that are driving the appropriate speed. I took the car to my Hyundai dealer and a tech drove it. He said he got the same result of not holding the speed it was set at. I was told this is a problem with the Smart cruise and that there was nothing that could be done at this time. There was nothing to say the cruise control was not working correctly.
Cruise control on the 2022 Kona is not viable. In the standard cruising gears the cruise control is unresponsive for a long duration resulting in reductions of speed of up to 11 mph at highway speeds, in traffic. The response of the cruise control to following a car can take up to 1 minute to actually try and recover speed.
The adaptive cruise control does not engage in a timely fashion when activated. The speed reduces 8-12 mph before it kicks in. Speed always decreases 5 to. 21 mph on every hill. This inconsistency causes traffic to bunch around me. The dealership says nothing can be done to fix the problem. This problem is so frustrating and dangerous that I no longer use the feature.
While driving on cruise control set for 45mph the vehicle accelerated to 53 mph. Noticed this multiple times. Also steering wheel making noise and at times hard to turn. All fluids at good level. Then burning smell coming and vehicle revs up when at stop light. And then hard to start. Have had multiple issues with this vehicle. Dealer states all is good. Hyundai is no help. This is a 2021, a new vehicle that should not be acting like this.
Adaptive cruise control is practical non-functional. There is a major delay when setting the cruise control speed before it actually kicks in. Speed can slow down upwards 10-15 mph below the intended set speed and take roughly 30 seconds. Once it engages its spotty with it's functionality. Depending on traffic scenarios it seems to reset the ability to re-engage cruise control and will again dropping down speed taking 15-30 seconds for before re-engaging.
The cruise control does not engage. When setting the adaptive cruise control I have had the car slow down 15-20 mph before turning the cruise control off because traffic is backing up behind me and I become a hazard on the road. I have taken it to 2 different dealerships, the one I purchased the car from and one that is closer to my home as I moved and now live in a different state from where I purchased the car. Both dealerships claimed they were not able to replicate the issue. However, every time I drive the car and try to use cruise control I have the same issue of the cruise control not engaging. The car dashboard's speed indicator is supposed to turn green and make a "ding" sound when you engage the cruise control at the posted speed limit. My car does not do this. The speed limit on the freeway here is 80mph and it will turn green and "ding" at 81mph but still not actually engage and maintain the speed. I have had numerous incidents where cars behind me honk and have to go around because I was slowing down so much. I spoke with another 2022 Kona owner and they stated that they have had the same problem and they were told the same thing by a different dealership that they bought their vehicle from.
Car lost speed on going uphill. Took car to dealer and they found nothing related. I am concerned about this recall. The length of time it has taken to repair and the fact that they do not know how to repair these piston rings.
On 30 may 21, I was getting ready to pull into my driveway, stopped the vehicle to let a passenger out of car, when suddenly the vehicle accelerated at a high speed crashing into my house. I nor the braking assist could stop the vehicle, resulting in the collision with house. I and my passengers sustained seat belt injuries.
When I drive the car on the street and freeway I have to hold the steering wheel in place so I don't go into the next lane. The car feels like it hydroplanes and shifts on the freeway. When turning the car shifts as well. The car bounces when driving and on the freeway when I go over a bump I have to pull the wheel so the car doesn't go into the next lane. The car lags when accelerating. One tire wasn't holding air so I took it to the tire center to have it fixed. The car drives this way everyday.
On Tuesday, March 2020, I pulled into a parking space at a local cvs store shortly after 5 pm, about to come to a complete stop and shift into park, when my 2020 Hyundai Kona suddenly and inexplicably accelerated, jumped the policeman, then the curb and rammed into the wall of cvs store. My airbag was activated and the car rolled back after the impact. There was no damage to the wall and the sheriffs deputy who arrived after the car's emergency notification system was activated did not make a report since the employees at cvs declined to press any charges. My vehicle sustained medium damage to the front end, but was drive-able. I sustained a very strong blow to my upper chest and have had problems breathing. I took pictures of the area but did not go to a doctor the same evening. I have been driving over 12 years and have not had a single accident or even a ticket in all this time and I am 100% certain I did nothing wrong!!! please rsvp ASAP !!! thank you.
