Adaptive Cruise Control Problems of Hyundai Kona

While the cruise is set, traveling on i44 with no other car in front of my Kona, the adaptive cruise control will start to flash and apply brakes immediately. The speed will drop instantly. Thankfully no other vehicle has been behind me, otherwise it would have caused a massive wreck. I have taken the Kona to the shop 5 to 6 times for this situation, but they will not do anything since they can not duplicate it. I took a video recording of it happening, and they still would not do anything. The first incident was December 31, 2024. This happens every other week when I travel out of town for my daughter parenting time with her dad.

While traveling from mn to ky on the interstate on two separate occasions the vehicle suddenly applied the brakes at highway speeds around of 80mph. There was nothing infront of me on either occasion. Then the next day it did it again at highway speed. Then I was driving on a mountain road in the smokies and it gave me a message that the front camera was blocked, and it was turning off the safety braking etc, I stopped when I could and took pictures there was nothing blocking the camera. I had a similar problem in March of this year which is documented by Hyundai customer service as the dealership told me that they could do nothing to help me.

I have two Hyundai vehicles one is a 2018 tucson and a 2019 Kona. They both broke down at precisely the same time at 109,000 miles. One was the catalytic converter dealership was going to charge $5,000 for repair found a less expensive place to do it for $2,000. I was told by several of the mechanics at both places that it was a common problem. My point is I just paid the vehicle off it was just out of warranty then your stuck with it. Dealership just shrugged it off as maybe you should buy a new vehicle. The second vehicle Kona had some catalytic damage but not enough to replace the crankshaft positioning sensor failed caused the car to basically shut down on the roadway all of the adas systems failed. Again dealership was going to charge $2,000 found aftermarket place to do for $1,000. I'm sure nothing can be done for me but I feel it should be documented if people in the industry are telling me this is a familiar occurrence then maybe someone should look into it.

Unknown I was backing out of a parking space using the back up camera when I bumped a vehicle behind me. Also, when driving on the highway, the cruise control doesn't always respond properly I just want to know if my car has the latest safety updates available for insurance purposes.

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.

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. .

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.

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.
