I was driving about 65 mph down the highway with my 3 children and husband in the car when out of nowhere my front sunroof EXPLODES. It sounded like a gunshot and was absolutely terrifying for my entire family. I went back and forth with Kia (dealership and service advisors acknowledged this is a known occurrence/recall for KIAs) however, after multiple attempts of a goodwill replacement, I was continuously denied.

"UPDATE TO EXISTING COMPLAINT the federal safety agency ID 11747231 LCD CENTER DISPLAY / BACKUP CAMERA FAILURE UPDATE TO the federal safety agency COMPLAINT ID 11747231 I am submitting an update regarding the same unresolved safety defect reported in the federal safety agency Complaint ID 11747231 involving my 2025 Kia Carnival SX. Mileage when the problem start approximately 8k miles. The vehicle has now undergone five repair attempts for the same recurring LCD/display failure. Repairs have included replacement of the LCD/display, replacement of the radio/head unit, work involving coaxial connections, and most recently repair of what the dealership diagnosed as “insufficient pin tension.” Kia Tech Line has also been involved. Most recently, I was told the vehicle was repaired and ready for pickup. However, when I arrived at the authorized Kia dealership, the LCD began flickering again while the vehicle was still in the dealership parking lot. Dealership personnel witnessed the failure and recorded video of it. The defect remains unresolved. The display has previously gone blank while driving, caused navigation to become unavailable, and caused the rearview/backup-camera image to become unavailable while reversing. This recurring failure is causing me significant stress and distraction while driving because I do not know when the screen will suddenly begin flickering or go blank again. When the screen unexpectedly flickers or fails while I am driving, it draws my attention away from the road. The loss of the rearview-camera image while reversing also creates a serious safety concern because I unexpectedly lose the camera view behind the vehicle. I regularly transport my family, including young children, and I am extremely concerned about these unpredictable failures. After five repair attempts, the same safety-related defect continues to occur without warning. I respectfully request that the federal safety agency associate this update with Complaint ID 11747231 and review this continuing safety defect.

The battery is draining due to external things but it’s not attached to anything and now all screens in the car flash on and off and go black including speedometer

On August 31, 2026, while traveling eastbound on I-14/US-190 in Killeen, Texas toward Temple, an original factory-installed Continental CrossContact RX 235/55 R19 101H tire on a 2025 Kia Carnival Hybrid suffered a major failure at approximately 28,975 vehicle miles. A toddler was a passenger in the vehicle. Prior to the failure, there was an unusual tire noise, followed by a much louder noise and the smell of burning rubber as the tire came apart. There were no known tire-pressure warnings or other warning messages before the failure. Fortunately, the driver was able to maintain control of the vehicle and safely pull off the highway. There was no crash, fire, or injury. Kia Roadside Assistance towed the vehicle to a Kia dealership. The failed tire was replaced. A service advisor at the dealership who personally observed the failed tire subsequently stated that what he observed was tread separation and not road-hazard damage. Approximately 7,091 miles before the failure, at 21,884 vehicle miles, a Kia multipoint inspection documented all four factory-installed Continental tires at 7/32-inch tread depth with “NO DAMAGE.” The tires had also received documented rotations during the vehicle's service history. The failed tire is no longer available for inspection. I contacted the servicing dealership the morning after the incident specifically regarding retaining the failed tire. When I later returned to the dealership to follow up, I learned that the tire had been disposed of. Continental was notified of the incident but has not physically inspected the failed tire because it was disposed of by the dealership. Three other factory-installed Continental CrossContact RX tires remain on the vehicle. I am submitting this complaint because of the serious safety concern associated with a reported tread separation occurring at highway speed and because three tires from the original factory-installed set remain in service.

Fuel evap canister leak was suspected due to very strong gas smell inside vehicle. Dealership had to change out entire fuel tank to deal with whatever was leaking. Got the car back, and the next day, the smell was back. Dealership told us not to worry about the smell, that it was normal. Drove one more time and smell was so strong that it made two adults dizzy and nauseous within five minutes. Nausea lasted multiple hours. Parked and had it towed to dealer. After multiple days, still waiting to hear back, service apartment claims they're waiting for research from Kia. Vehicle has been too dangerous to drive so sitting at dealership for nearly 30 days now, total. No warning lights or messages ever came on to notify us of the problem.

The vehicle's passenger cabin continually has a strong odor smell after longer drives or after the vehicle idles for a longer duration in time. The vehicle was brought to Horne, KIA in Gilbert, AZ twice in June for same. Both times the service department stated they could not duplicate the problem and could not ascertain that it has anything to do with recall SC368. The problem continues at time of this writing (07/14/2026). The strong fuel odor is causing headaches to family and young children. The problem could not be reproduced but matches the SC368 recall. KIA Customer Service was contacted today, and they advised the only thing they can do is trust their authorized service department that there are no concerns (Horne KIA). I requested the matter be escalated, but my request was denied.
