"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.

**Vehicle:** 2025 Kia Carnival **Current Mileage:** Approximately 18,000 miles I am reporting a serious and ongoing safety defect involving the center LCD display in my 2025 Kia Carnival. The problem began immediately after the vehicle's first scheduled service at an authorized Kia dealership and has continued ever since. The center LCD screen intermittently flickers and then goes completely blank while I am driving. When this happens, the rearview camera image is also lost while the vehicle is in Reverse, leaving the display completely black and preventing me from seeing behind the vehicle during backing. This creates a significant safety hazard and increases the risk of striking a pedestrian, child, vehicle, or other object. The display failure while driving is also extremely distracting because critical vehicle information and functions become unavailable. I have taken the vehicle to authorized Kia dealerships multiple times for warranty repairs, but the defect remains unresolved. The LCD display has been replaced, yet the problem continues to occur. The dealerships have kept my vehicle for extended periods during several repair attempts without permanently correcting the issue. Service dates include: * September 9, 2025 * March 10, 2026 * March 18, 2026 * June 1, 2026 The issue is intermittent but repeatedly occurs without warning. I transport my family, including infants, in this vehicle, and I am extremely concerned about their safety and the safety of others. Losing the backup camera and display while reversing or driving creates an unacceptable safety risk. I believe this may be a safety-related defect affecting the vehicle's display system. I respectfully request that the federal safety agency investigate this issue because multiple warranty repair attempts, including replacement of the display, have failed to resolve the defect.

We have been having persistent safety issues with this vehicle. The issues have ranged from unsecured gas cap to loss of power. We’ve also had severe transmission issues where the car will not shift out of first gear. This happened on the Garden State Parkway and nearly caused an accident as the car wasn’t able to go above 27 mph safely.

For the third time the 2025 KIA Carnival Prestige I own lost power while driving on the interstate! Without warning, the vehicle would no longer respond to the accelerator pedal. No matter what I did I could not get the vehicle to accelerate past 35 mph. The minimum speed limit on the interstate is 45 mph. I had to immediately engage my hazard lights and make my way over to the shoulder of the road from the passing lane. This was a dangerous situation for me and my family and others on the highway. Warning lights came on, check engine light, charging system, and a maintenance service message. Driving in Sport mode, Smart mode, nor Econo mode could change the negative situation. This took place multiple times during the final leg of my last trip to [XXX] , extending for over 120 miles. This is a very unsafe, unreliable vehicle, that should never be driven on public roadways… especially not highways nor interstates. Three negatively, traumatic experiences is ENOUGH!!! I’m DONE!!!!
