2022 Hyundai Kona: adaptive cruise control problems

Filed Nov 12, 2024 · Engine · TX

On 10/4/2024 I was driving my 2022 Hyundai Kona SEL (61, 492 miles on odometer) with a cruise control set at 75 mph for my morning commute into work. I was approx 15 miles away from my house and at least 7 miles away from my place of employement. Suddenly and without warning the engine revved to beyond 4500 RPM and shut off. The lights on the dashboard all lit up and a message flashed on the screen stating engine cut off, turn off car and restart. I was surrounded by several cars at this time. I was able to navigate to the shoulder of the 2 lane road I was on and bring the car to a stop. When I tried to turn the car back on it would not. I had the car towed to the dealership. First they had to replace the battery as they stated there was not even enough juice in the battery to update the onboard computer for diagnostic. Then, after a week of waiting, I called and was informed that the engine was deak (advisor used the phrase "the engine when clunck"). As of today, 11/12/2024, I do not have a full diagnosis for the engine failure as the dealership has yet to inform me even though I have submitted multiple requests through various means. Service advisors states that the engine will be covered under the CPO warranty. At the time of the incident, the engine had not given any indications of any issues (like noices, stalls, etc). My sister had driven the car two days before and said it was driving fine. I had had the oil changed a week before and the tech did an inspection at that time and all parts were in working/good condition.

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.

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.

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

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. https://www.konaissues.com/ https://www.hyundai-forums.com/threads/2022-kona-cruise-control-unusable.680949/ https://www.reddit.com/r/Hyundai/comments/q80vhz/cruise_control_in_2022_kona_limited_is_whack/ https://www.carproblemzoo.com/hyundai/kona/2022/adaptive-cruise-control-problems.php

During collision, airbags did not deploy. In attempt to avoid collision, automatic breaks failed and did not stop the vehicle, cruise control continued to attempt to drive the vehicle despite collision warning and did not stop- coupled with my manual breaking, the car did not stop. Car is currently at a tow lot waiting for insurance. My safety was put at risk due to airbags not deploying during serious collision, the breaks malfunctioned. At this time, the car is in the beginning stages of insurance. My car did not display any prior failure features.

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.
