2023 Kia Sportage Hybrid Acceleration Problems

Owner reports

Selected complaints filed with NHTSA by 2023 Kia Sportage Hybrid owners, lightly cleaned up (personal details are redacted by NHTSA).

While on a 65 mph enforced highway, cruise control was turned on via the button on the steering wheel. The digital cruise control set itself at 110 mph and the vehicle began to accelerate to match the speed. Aside from turning on the cruise control, no other buttons on the steering wheel were pushed. The car's cruise control feature had previously been set at 70 mph to match current conditions and was used regularly throughout the length of the trip. While the car continued to accelerate on its own to match the self-set speed, we tried to decrease the speed both by trying to set it at the current speed, and by holding the dial down to decrease the speed manually. The car did not reflect any changes in speed and a message popped up saying "Cruise Control conditions not met" and it tried to disengage cruise control and acceleration. …

After driving for roughly 7 hours upon activating my cruise control, after using the entire drive with no issues, it went up to 110 mph as soon as I hit the button and would not allow me to adjust the speed down. It would turn off upon pressing pause, cruise control, or brakes but would rise to 110 mph everytime. I searched for recalls for this and could find none. But I did find posts of other people with the same issue. The only thing I could find was an emissions campaign that seems like it may be related. This appears to me to be much more of a safety issue especially if the driver is not paying attention. Or for example let's say you're driving behind someone and turn cruise control on you could very easily rearend someone at a high rate of speed. …

I've had two issues with my 2023 Kia Sportage cruise control. 1. When I press the 'set' cruise control button, it will set at a speed far grater than I'm driving and escalate to that speed. Example: I'm driving 65 on the highway. I set the cruise control. It sets to 100 mph and quickly gains to that speed. This has happened about 5 times. It doesn't happen every time I try to use cruise control. The last time it happened, I could click the 'set' button to disengage cruise control but it would never set to 60 mph- always 100. So I pressed 'set' at 60 MPH. It went to 100 MPH. Then I pressed Set to disengage. Then pressed 'set'again at 60 MPH and it went to 100 MPH. The only way to get it to actually re set was to pull over and re-start the car. 2. When you actually get it to 'set' to 60 MPH and then press the toggle to speed up, it will often toggle up to 90 MPH instead of to 65MPH. …

I purchased my car in August 2022, and the cruise control issue began in September 2023. It occurs randomly and significantly makes me feel UNSAFE in my vehicle. I have not been able to enjoy full use of my vehicle. Kia has been aware of this issue since at least April 2024 (when they first called me), even though I made my report to the NHTSA in October 2023 (NHTSA ID: 11549711). Today, Kia informed me that the video that I risked my life to take of my car almost killing me and other road drivers was not enough and that they could not replicate the issue. The response time from my case manager has literally been atrocious. These issues have significantly limited my use and enjoyment of the vehicle, making me regret my purchase. I did not expect to rely on rentals without the features that led me to choose this car, especially due to delays in addressing my case.

The vehicle frequently fails to engage gas engine when depressing gas pedal to any degree. A full push of the gas pedal does not result in gas engine engagement. This has happened over 15 ties since the recall computer update last summer (2025). This creates extreme danger because the operator expects the full power of the engine to engage when pulling out of intersections or crossing oncoming traffic, but the engine does not engage causing a slow, creeping acceleration from the electric motor only. I took it into the Kia dealer and they found nothing wrong. No warning lights occur when the malfunction happens. And no check engine lights occur either. The only correction is to fully turn the vehicle off and back on. Doing that resets everything back to normal. This malfunction usually occurs within the first 25-30 minutes of vehicle operation.

I had a number of systems suddenly cut out on me. The dealership thinks it was a fuse or fuses that went bad. They affected the car's following systems: * Primary Instrument Cluster (Left side) * Forward Collision Avoidance-Assist w/Car, Pedestrian and Cyclist Detection * Advanced Collision Avoidance (Auto-breaking) * Lane Following Assist * Lane Keeping Assist * Driver Attention Warning w/ Leading Vehicle Departure Alert * Blind-Spot Collision-Avoidance Assist (In Mirrors) * Door Unlock Warning (I received several warnings that my doors were unlocked even when they were locked) * Entrance/Exit Chime * Blinker Sound * Compass * Internal Navigation (GPS worked but because the compass was broken, the mapping system did not know which way my car was traveling.) * Fuel Efficiency was incorrect. I never got above 31 miles to the gallon

I was driving for approximately 30 minutes, using cruise control as needed. There was a decreased speed area so I toggled down to reduce speed from 65 to 55. My cruise control speed jumped from 65 to 110. NOTHING I did would reduce the speed. I had to turn off the cruise control to get control of my vehicle again. I thought I did something wrong so I turned on cruise control and attempted to set the speed again. Immediately upon using the toggle to set the speed, the speed jumped to 110. This happened several time and I couldn't get cruise control to work correctly for approximately 30-45 minutes. Finally I found a safe area to pull off the interstate, turn the vehicle off and back on. At which time the speed controls began working correctly again. Very scary and unsafe situation!

While driving on the highway at 80 mph, the accelerator suddenly stopped working and was completely unresponsive. The dashboard displayed the message "Check Hybrid system. Stop safely" and a warning ding sounded. The gas engine was still operating and showing RPMs on the dashboard, but all acceleration and/or engagement with the engine was lost. I was able to coast and safely pull over to the side of the road. After pulling over, I turned off the engine and pushed the 12v battery reset button. The car restarted, and I was able to continue driving. The issue repeated about 20 miles later and again on a different drive four days later. Each time, there is no early warning or noticeable issue with the vehicle before the sudden warning and loss of power.

I have had three separate instances over the past year, most recently days ago, where I pressed the cruise control button, then pressed the cruising speed increase button, and the cruise control setting jumped to 110 mph. I could press the cruise control button again to turn off cruise control, but if I pressed cruise control again, it would immediately jump to 110 mph, no matter what my current speed was. Pressing the decrease cruise control speed button didn't lower the cruise control speed. The only workaround is to turn the vehicle off and the turn it back on. There are multiple online forum posts, and several YouTube videos, of other Kia Sportage owners experiencing the same problem.

3 times in the last two days, and dozens of times over the last six months, while driving or while idling, the "check hybrid system" warning has flashed. When it happens the car does into limp mode, where it will go no faster than 13mph. this has happened in the left lane of a highway where there is no where to pull over except the lane, since there is no time to get over before the vehicle shuts down. the car essentially will shut down in the middle of driving, no matter where it is. Especially with my kids in the car it is terrifying hazard. I have brought the car to the Kia service and since its not easily reproducible they have not been able to help and have offered no solutions.
