2022 Hyundai Kona

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.

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.

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.

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

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.
