Owner reports
Selected complaints filed with NHTSA by 2023 Kia Sportage Hybrid owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2023 Kia Sportage Hybrid. The contact stated while driving at 13 MPH from an exit and entering a roundabout, a right turn on an incline was attempted to be made when the vehicle veered in the left direction independently violently. The contact also stated the driver assist was engaged and the vehicle went off to the side of the road and over an embankment where the vehicle came to a stop. The contact mentioned that the driver assist failed to disengage to give the contact control of the vehicle and the brake pedal was depressed but failed to respond. In addition, the wheels locked. The contact sustained bruising on the left side of the body. No medical attention was required. The vehicle was towed to an independent mechanic but no diagnosis was completed. The vehicle was not repaired. A police report was not filed. …
The contact owns a 2023 Kia Sportage. The contact stated that while driving at an undisclosed speed, there was smoke coming from the engine compartment and the vehicle stalled. The check engine and battery warning lights were illuminated. The vehicle was towed to a dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 104,000.
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. …
I was driving east from Austin, Tx on [redacted], and as I approached a major intersection in Elgin, Tx., a warning light appeared on my dashboard that said "hybrid system failure: pull over safely". I was able to pull over into the left turn lane and then was barely able to make it over a curb and onto a highway median strip, before my car engine stopped and all dashboard lights went out. This happened in about 30 seconds. My two year old car with fewer than 30,000 miles on it went completely dead. It would not start even after several attempts. I called Kia roadside assistance, and was told I needed to have the car towed to a dealership. The tow truck driver backed the car into the space they indicated at the dealership, and it started to roll forward as it was apparently in neutral. He had to borrow a board to put under the back wheels. …
The hybrid powertrain system failed. Specifically, the vehicle remains stuck in EV mode and does not switch to the gasoline engine under acceleration, leading to complete loss of power while driving. Yes, the vehicle is available for inspection upon request. This malfunction caused the vehicle to lose all forward power in traffic. I had to pull over into emergency lanes and restart the vehicle multiple times. This is extremely dangerous and could lead to a crash, especially on highways or during merging. It puts both myself and others on the road at risk. The Kia authorized service center was able to reset the adaptive system, and the hybrid warning light turned off temporarily. However, the issue reappeared the same day. The dealer claims they cannot reproduce it and refuses further diagnosis without replication. The vehicle was only inspected by a Kia-authorized dealership. …
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 am filing a safety complaint regarding my 2023 Kia Sportage Hybrid. The vehicle developed a "Check Hybrid System" warning and was diagnosed by a Kia dealership as having a failure involving the high-voltage hybrid system, specifically the MCU (Motor Control Unit). The dealership informed me that the vehicle may be unsafe to drive due to the possibility of fire risk associated with the high-voltage system. I was told technicians had to use specialized protective equipment while diagnosing the issue and that the diagnosis process took nearly a week. The repair estimate was approximately $5,000, in addition to approximately $750 charged for diagnostics alone. The vehicle is reportedly out of warranty due to mileage, even though this appears to involve a major hybrid system component and a potential safety defect. …
Was driving my child to school when the Hybrid System alert came on, I only had a few seconds to try and pull over before the car completely shut down, we lost all motive power. I was on a downward incline right in front of an uncontrolled intersection with very little shoulder as I live in a rural mountain town. Since the parking brake is part of the integrated system I did not feel I had full control of the car while pulled to the side and even moved a bit while trying to wait to restart the system via the 12volt re-set button. This was a very serious safety issue, the difference of less than a minute could have led to my child and I being helpless in the middle of a highway intersection. This is a reoccurrence of a previously documented problem from April of 2026. …
I was driving my 2023 Kia Sportage Hybrid when the vehicle displayed a "Check Hybrid System"/ "Stop Safely" warning and suddenly lost motive power/acceleration. I was unable to accelerate normally. I had luckily pulled of the road that I was going 55 mph into a parking lot prior to the lass of power or I would have stopped right on the roadway with cars going the same speed directly behind me. This created a serious safety concern because if this had occurred while traveling at highway speed or in heavy traffic, the sudden loss of power could have resulted in a collision. There had been no indication to me that the vehicle was about to lose motive power before the hybrid-system warning appeared. The vehicle is currently at an authorized Kia dealership for inspection and diagnosis. The cause has not yet been provided to me. The vehicle is available for inspection. …
Traveling at 70 MPH on [redacted] in traffic, the vehicle suddenly lost power and I was forced to unsafely maneuver to the shoulder of the road as the vehicle decelerated through the traffic. As soon as I stopped, the vehicle lost all power. I had difficulty engaging the parking brake as I was on a hill and the vehicle started to roll back. The brake pedal did work so I could stop the car but I could not exit the vehicle in fear of it rolling back into traffic. I called 911 to explain the situation. After 20 more minutes I engaged/disengaged the parking brake several times and it finally held. I still would not leave the vehicle because I could not trust it at that point. Another 20 minutes passed and a road ranger arrived and placed a wooden block behind the wheel and at that point I felt comfortable to get out of the car. …
