2026 Kia Sportage Problems

While adaptive cruise was engaged, the vehicle read Alabama highway 80 west state road sign and incorrectly interpreted the sign for a speed limit sign which is 55 MPH.The vehicle displayed a “80 MPH” speed limit sign on the instrument cluster and then began to accelerate. When I took it to the dealer for repair, the “turned off safety feature”.

My car had begun to accelerate when pressing the brake pedal. The first time it happened the car kinda stuttered as it fought itself, but the car stopped. That was also the only time it stuttered and corrected itself. The next few times it happened, the car was not as easy to control but was able to stop safely. I took the car in to the dealer to have it checked, but the problem could not be replicated. I even told the dealer the date and time of one of the events and they weren't able to do anything with that information. Just hours after I picked up the car from the dealer, it happened again. Only my daughter was driving and the car just took off as she was braking. She wasn't able to stop it, and the fail-safes that are supposed to avoid accidents and force the car to stop never kicked in. We rear-ended someone not going very fast since she was far away from them when she began to brake. But since the car started accelerating, it was enough force to have both airbags deploy and wreck the car. Kia Corporate requested that we send the ACU to them, but when no one was available who could do that, they said their hands were tied and wished me well. The insurance company offered to have them send someone qualified to pick it up, but they just washed their hands of the entire case. My case # with Kia is 26150176. Had this been the only car affected, I would be less concerned... but my husband's 2025 Sportage SX-Prestige has also been having the same issue and also has an open case with Kia Corporate. He's just had better luck in stopping the car once it takes off. And the dealer looked over it and tried replicating the issue in his car too with no luck. His case # with Kia is 26150395. The strange thing though is that this issue started happening to both cars very suddenly. I had had my car for 9 months before it was totaled, and it only started happening to both cars less than a month before the accident.

When attempting to disengage the cruise control, I must apply sufficient force as to actually apply the brakes. My expectation is that a simple tap on the brake pedal would release the cruise control and begin a coasting mode. This is not the case; the SUV continues at the same forward speed until I press the brake pedal the second time a little harder.

Odometer Fraud. The contact owns a 2026 Kia Sportage. The contact stated that after purchasing the vehicle, it was determined that there was a mileage discrepancy. At the time of the purchase, the mileage was 0. The vehicle was a dealer sale. The document from the dealer indicated that the mileage was 488. The vehicle was a used rental vehicle prior to the purchase. The contact determined that the actual mileage was 1,060. The contact called the attorney general and Penn DOT regarding odometer fraud.

I am reporting two separate safety-related failures on this low-mileage vehicle. The first occurred at 2,431 miles while driving on the highway. The vehicle suddenly lost propulsion and coasted with no throttle response, and multiple warning lights and messages appeared simultaneously, including braking, electronic parking brake, and driver-assistance warnings. A sudden, unexpected loss of power at highway speed creates a serious crash risk, including rear-end collision, particularly with faster or following traffic. The vehicle was taken to an authorized Kia dealer on 3/9/26 and returned on 3/19/26 after wiring/connector-related work. The second failure occurred at 4,658 miles when the panoramic sunroof glass suddenly shattered while the vehicle was in motion. A spontaneous glass failure while driving is a safety hazard: had the interior sunshade been open, falling glass could have struck rear-seat passengers, and shattering glass while driving can cause driver distraction and loss of vehicle control, as well as a road hazard to surrounding vehicles. The vehicle was taken to the same authorized Kia dealer on 4/1/26 and remained there until 5/21/26. The sunroof was not repaired. The dealer's repair order states that it "cannot identify a specific outside object or cause" and that "no damage was found clearly identifying an external object as the cause," which is consistent with a spontaneous glass failure rather than external impact. Despite this, warranty assistance was denied on the basis that an outside impact "could not be ruled out." I am concerned these represent defects involving the panoramic sunroof glass and/or the vehicle's electrical and safety systems. Both failures occurred well under 5,000 miles and within months of each other. Across the two repair visits, the vehicle was out of service for approximately 60 total calendar days, including roughly 50 days for the sunroof issue, which remains unrepaired.

The glass piece that sits between the front windshield and the sunroof cracked from side to side of the car. When I called the dealership to get it repaired they said this has happened to a few models with this same type of glass between the windshield and the sunroof.

I am reporting a potential safety issue involving the lane assist system on our Kia Sportage. On Monday morning, my wife was driving on a straight road and began turning left onto a side street. During the turn, the vehicle’s lane assist system suddenly applied a strong steering correction. The steering wheel jerked unexpectedly and momentarily resisted the driver’s attempt to correct the steering. This sudden steering intervention caused the vehicle to veer toward a guardrail, resulting in a collision. The driver did not intentionally steer toward the guardrail and attempted to correct the vehicle, but the steering wheel resisted input at the moment the lane assist system intervened. A dashcam in the vehicle recorded the incident, and the responding police officer reviewed the footage at the scene and concluded that the steering wheel jerked toward the guardrail. The police report notes that the accident appeared to involve a possible vehicle malfunction. After the incident, we discovered that this vehicle is included in NHTSA Campaign 26V046000, which states that a software error may cause the instrument panel display to fail to show critical safety information such as warning lights. If a malfunction warning occurred but was not displayed, the driver would not have been aware of a problem with the system. The lane assist feature in this vehicle also automatically reactivates each time the vehicle is started, meaning the driver cannot permanently disable it. Because the steering intervention occurred unexpectedly during a normal turn and resulted in a collision, we are reporting this incident so it can be reviewed as a potential safety defect involving the lane assist or related vehicle systems.

The contact owns a 2026 Kia Sportage equipped with Kumho Tires, Tire Line: Crugen HP71, Tire Size: 235/60/R18, DOT Number: 1K2CMYA8E . While the contact’s daughter was driving approximately 75 MPH, the vehicle suddenly started shaking violently and vibrated abnormally, causing the driver to almost lose control of the steering wheel. The driver regained control of the steering wheel and parked the vehicle. The Police and a towing service was called to the scene. Upon inspection, it was discovered that the front passenger’s side tire had tread separation at the center of the tire, causing the center rim of the wheel to be exposed and caused damages to the wheel well and fender. The vehicle was later towed to the residence. The cause of the failure was not yet determined. The vehicle manufacturer and rental car company were notified of the failure. The tire manufacturer was not yet contacted. The failure mileage was 3,900.

I turned on my vehicle and began driving in Philadelphia. I noticed the dashboard where the speedometer was supposed to be was dark. The Apple car play on the right side of the dashboard was on but no other components were visible. Such as turning signal, lane keep assist, speedometer, etc. I was on the highway and this was extremely scary. This vehicle has less then 200 miles. I’ve taken it to Kia and they are looking into it. But this is a big concern. I have videos of this but it won’t let me add them to this file.
