2024 Kia Sportage: adaptive cruise control problems

Filed Feb 15, 2026 · Acceleration · MI

I was driving on the highway and had set the cruise control to 76. I then pushed the plus button once to increase the cruise control speed and the cruise control increased immediately to 110 mph. I braked right away which stopped the acceleration but could see it was still set at 110 mph. I pushed the button to turn the cruise control off. When I pushed it again, it went immediately back to 110. I tired multiple times over the next 45 minutes to turn the cruise control back on but it always went immediately to 110 mph.

A month after buying my vehicle in February of 2024, while driving my vehicle the screen behind my steering wheel will black out and come back on and do a system check as if I had just turned my car on. It happens at all times of day, at all speeds. I kept a log of some of the incidences and there are no two that are the same. I have even been in park with the car on and it will happen. When you are driving with cruise control on and it does it the cruise control shuts off then comes back on after it has done the system check again. This is extremely dangerous while driving on the interstate and a line of cars around you. I have taken it to the dealership and they have worked with Kia to try to figure it out and still have not been able to. I am now going on almost two years of this happening without any resolution. Below I put the last time it happened but this happens ALL the time and is not one isolated incident. I have attached a log I kept for two months of the incidences.

Two issues that I've taken to dealership 3 times since purchasing vehicle January 2024. 1. Adaptive cruise control -- I was in right lane of 4 lane highway with cruise control on. A car in left lane took a turn to cut through median and my car thought it was a collision and hard braked and took my vehicle from 60mph to 35mph in a few seconds. If a car had been behind me, I would have been rear ended. They cannot "replicate" so I no longer use cruise control unless there are no cars around. 2. Timing has been off (loud clicking every time I crank) since a few months after I bought the car. I sent approximately 9 videos to the service advisor. Took it in 2 times "cannot replicate." Left it overnight at dealership "cannot replicate." It's every time I first crank for the day. It's now louder and gotten worse. I have videos and can take more. I just want this fixed. Afraid I'll be stranded and it feels like they are pushing it farther and farther out so it will exceed warranty and they won't have to eat the cost to repair. It's been 1.5 years I've been dealing with this. Any help you can provide is greatly appreciated!!

While traveling on a 4-lane highway and using cruise control, a car in the left-hand lane was making a left turn across a median cut through, and my car's sensors detected a collision and took me from 60 mph down to 35 mph in about five seconds. If a car had been behind me, it would have rear ended me. I no longer use the cruise control for this reason. And yes, my sensors were clean. I had just gotten the car cleaned within a day or two prior. I have an appointment this coming Monday to take it to the dealership, to have them look at it. Separate incident. While parked in a parking lot, came out of restaurant and cars were parked very close on either side of my car. My car's sensors detected collision and would not let me back out. I had to pull forward and try to go back numerous times before it finally released the collision warning and allowed me to back out. This happened many months ago, but I am just now having the time to take it and drop it to the dealership because they want to keep it all day.
