2026 Kia Sportage Problems

I am writing to formally report a severe and life-threatening safety defect regarding my 2026 Kia Sportage Hybrid. On September 28, 2026 around 8 am, I experienced a terrifying Sudden Unintended Acceleration (SUA) event while operating the vehicle. I was completely stopped at an intersection, waiting to make a left turn. The vehicle was stationary with the AUTO HOLD function engaged. When it was time to proceed, I lightly pressed the accelerator pedal to begin moving. Instead of accelerating normally, the vehicle dangerously surged and accelerated on its own. I immediately removed my foot from the accelerator pedal and attempted to stop the vehicle by repeatedly pressing the brake pedal. However, the vehicle did not slow down as expected and continued moving at a high speed. At this time, my foot was completely off the accelerator. The unexpected acceleration lasted for approximately 10 seconds. While repeatedly applying the brake pedal and trying to maintain control, I managed to steer the vehicle into a nearby side street/alley, where the vehicle eventually came to a stop. Fortunately, there was no collision, injury, or property damage. However, this was an extremely frightening and dangerous event. No warning lights or error messages were displayed on the instrument cluster during or after the incident. I requested the Kia Tustin dealer for Inspection and Data Preservation. I also reported to Kia Amerca.

Wiring harness keeps getting chewed up by rodents in engine bay. Had to have Kia fix 2 times for the parking distance sensors. Have done lots of prevention things to keep from engine bay, but attracted to this vehicle. My 2 other vehicles no problems. They are not Kias. It causes loss of driver assistance systems.

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.

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.

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 2026 Kia Sportage X-Line was involved in a multi-vehicle rear-and-frontal collision. While stationary waiting to turn from a highway to a secondary road, my vehicle was struck from behind and pushed forward into an oncoming vehicle then continued into guard railing. There were no tire marks from the rear at fault vehicle to indicate any attempt to brake prior to impact. The resulting frontal impact caused severe crush damage extending all the way back to the radiator and significantly bent the hood. Despite the severity of the frontal collision—which caused enough structural damage for the at fault insurance company to declare the vehicle a total loss—none of the vehicle's airbags (front driver, passenger, side, or curtain) deployed during either impact. Prior to the crash, no airbag or Supplemental Restraint System (SRS) warning light was illuminated on the dashboard (note: this vehicle model year is subject to Kia Recall SC361 / NHTSA 26V-046 regarding instrument panel display failures that can omit warning lights). The driver sustained minor injuries in the collision. The vehicle is currently declared a total loss and stored at an insurance salvage facility pending title transfer, and the Event Data Recorder (EDR) has not yet been downloaded.

A deer ran out on the parkway when I was coming home from work and it totaled my vehicle. The ambulance had to pry the door open to get me out. The airbag never deployed and the seatbelt popped open.

When driving into the sun, thousands of tiny dust like sparkles illuminate in the windshield. These dust like sparkles can and do obstruct vision through the windshield. This has been a problem since the day I putchased my new 2026 KIA Sportage SX Prestige Hybrid from KIA of Portland on July 30, 2026. I took attached photo with my cell phone and you will need to zoom in a bit to see sparkles.

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.

The contact owns a 2026 Kia Sportage. The contact stated that his wife had driven for 6.5 hours at 35-70 MPH with the seat heater activated, the seat heater overheated. Upon exiting the vehicle, the driver discovered second-degree burns on her right thigh and significant bruising extending from her left thigh to her buttocks. The contact stated that the failure had occurred while the contact and wife were traveling on a 6.5 hours trip. The contact's wife received medical treatment for the injuries. The manufacturer was contacted by phone and a case was filed. The failure mileage was approximately 14,223.

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 vehicle has developed a persistent, severe rattling noise coming from the engine bay and front chassis area. The noise becomes significantly worse and amplifies at highway speeds, raising severe concerns about high-speed mechanical instability. The vehicle has undergone multiple repair attempts at an authorized dealership, but mechanics have been unable to identify or resolve the root cause of the noise. The vehicle is currently considered unfit for road use and has remained restricted to the dealership repair facility for 29 consecutive days since October 2, 2026. Because the source of this heavy mechanical rattle cannot be identified by factory technicians and worsens at speed, it presents an immediate safety risk. An unresolved, unknown mechanical defect in the front end or engine compartment raises serious concerns regarding potential sudden component failure, steering/suspension compromise, or structural detachment while operating at high speeds, which could result in a catastrophic loss of vehicle control.

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.
