2024 Kia Sportage

On December 24, 2025, while driving in traffic, my Kia Sportage experienced severe lurching, bucking, and jerking, causing the engine to shut down. All dashboard warning lights illuminated, including a message prompting me to "turn engine back on." The vehicle would not restart, necessitating a tow to Horne Kia. After several days of diagnostics, it was determined that a blown ignition fuse and a bad fuel pump relay were the issues, along with a battery replacement. However, just 19 days later, while attempting to merge onto the freeway, the vehicle again bucked violently, and the engine shut down with all warning lights flashing. The police had to assist in moving my vehicle out of traffic, and it was towed to Courtesy Kia in Mesa, AZ. Once again, no error codes were found. After further diagnostics, it was discovered that the same ignition fuse had blown and that the catalytic converter had "shattered." The catalytic converter was replaced. Upon picking up the vehicle from the dealership, and driving less then 5 miles on freeway, the vehicle was bucking and hard shifting once again resulting in a third tow to dealership just 48 hours later after the previous service. The dealership ran several diagnostics under Kia's tech line, which revealed that the engine pistons are slipping and not functioning properly, resulting in loss of compression. Per Kia's tech line, a new engine long block was ordered and replaced.

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.

The contact owns a 2024 Kia Sportage. The contact stated that while driving at an undisclosed speed, the sunroof exploded. The contact stated that there was no evidence of an impact on the sunroof glass. The dealer was made aware of the failure. The contact was advised to take the vehicle to a Collision Center for assistance. The vehicle was taken to the Collision Center, and the contact was informed that the failure was a known failure with similar vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact was advised to contact the NHTSA Hotline and the manufacturer to report the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 28,525.

While driving the vehicle and selecting EV only mode the engine RPMs surge to about 3000. This happens frequently and I have it on Video. Kia has had the car multiple times for electrical may electrical related repairs but say the vehicle is normal. The tech line person even had the dealer drive a similar car for a baseline. I would expect they had a baseline prior to manufacturing the car. This is an ongoing unrepaired issue. Date below is first reported date of electrical concerns.

Blank Instrument Panel Screen. abnormal CAN message which can cause certain instrument clusters with a 4.2” screen to reboot while driving. During this rebooting, the cluster will not show information such as the speedometer or telltales for approximately five (5) seconds. As a result, the subject vehicles do not comply with the visibility and illumination requirements of FMVSS 101, §§ S5.1.2 and 5.3.1

6” Snow ice storm & negative degree temps 12/13/25 used heated windshield deicer. On 12/15 driving to work on a country road no other traffic, heard pop cracking noise above my head checked sunroof snow ice melting no visible cracks thought noise from thawing ice. Parked vehicle in my home garage while I went out of town. Returned home 12/22 found large crack origination point in front windshield originating in glass down the middle of rear view mirror sensor housing black box mounted on inner windshield the crack spans from top middle to bottom of black box glass over to right center half of windshield. Believe this is a manufacture defect design flaw low quality integrity of glass weaker than standard glass making it more susceptible to temperature changes or minor impact. Entire crack feels smooth interior exterior glass as if the crack is in the inner layers of glass windshield. Due to multi complaints & prior class action lawsuit regarding manufacture defect of KIA windshields I am reporting my complaint as it is quite similar to others complaints, issues & lawsuits. The massive crack in windshield is a driving safety hazard & a manufacture defect that needs recalled & resolved before injury or death occurs. KIA must acknowledge, issue recall &/or post a bulletin, accept responsibility this is a manufactures defect, notify the public and replace the windshields under Good Faith Customer Relations Warranty

While traveling at approx 65 mph on a clear, debris-free Alaska highway in -5°F temperatures, the panoramic sunroof of my 2024 Kia Sportage spontaneously shattered with an explosive sound. There were no vehicles in the immediate vicinity (nearest car was maybe 50 to 75 ft away) and no observation of flying debris or falling objects from overpasses. The failure appears to be a spontaneous glass breakage (SGB) incident potentially caused by thermal stress or manufacturing defect rather than external impact. Crucially, some of the remaining glass fragments and one large attached piece are displaced and flexed OUTWARD (upward toward the sky). There are also fracture lines in the remaining glass along and parallel to the sides of the vehicle as well as parallel to the front frame of the glass. They do not radiate out from a central point as one would expect from an object strike. This geometry to me indicates internal tension or cabin pressure release, as an external impact from a projectile would have forced the glass inward into the cabin. Additionally, there was very little glass in the vehicle cabin, certainly far less than one would expect given the size of the opening in the sunroof and the amount of glass missing. I have personally previously been in a vehicle whose side window was blown out from a vehicle kicked rock strike and in that case was showered with a lot of glass. Yesterdays catastrophic failure resulted in some glass intrusion into the passenger cabin at highway speeds, creating a severe distraction with sound was loud & sudden enough to potentially cause a loss of vehicle control. I am aware of similar reports regarding the 2023-2024 Sportage (and previous Kia panoramic sunroof class actions) regarding the use of ceramic glazing or assembly stresses that contribute to such failures. I request an investigation into whether the current model's panoramic roof assembly is capable of withstanding extreme thermal differentials and body flex.
