Kia Carnival Electrical problems by year

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 NHTSA associate this update with Complaint ID 11747231 and review this continuing safety defect.

brought to Kia of Columbia, Connecticut, for evaluation. During diagnosis, the service technician was required to force the door open. Once opened, the door could no longer be closed. The dealership determined that the power sliding door motor actuator had failed and required replacement. When I arrived to pick up the vehicle on [[redacted]], the sliding door remained stuck in the open position and could not be latched or secured. Because the door could not be closed, the vehicle was not safe to operate on public roads and was effectively undrivable. The replacement actuator was ordered on September 21, 2026. The part did not arrive until September 29, 2026, and repairs could not be completed immediately upon arrival. The actuator was finally replaced and repairs completed on September 30, 2026. As a result, the vehicle remained unusable for approximately twelve days due to the inability to safely secure the sliding door. This failure presents multiple safety concerns: The vehicle could not be legally or safely driven because the sliding door would not close or latch. Occupants were exposed to an open side doorway if the vehicle were operated. In an emergency, passengers could be placed at risk due to door system malfunction. Failure of a critical door component rendered the vehicle unusable without warning. I am particularly concerned because Kia has previously recalled Carnival vehicles for safety defects involving power sliding door INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

noticed that the seat/floor rails and other exposed metal components in and around the second-row passenger area became extremely hot to the touch. I could only keep my hand on some of these metal components briefly before the heat became too uncomfortable and I had to remove my hand. I am concerned about the safety of this condition because these hot surfaces are in an area routinely accessed by passengers, including children entering and exiting the second row. I am concerned about the potential for contact burns as well as whether the amount of heat being transferred into the floor, rails, and surrounding components could indicate an exhaust, emissions, heat-shielding, or other mechanical problem. The vehicle is available for inspection upon request. At this time, the exact component or system responsible for the excessive heat has not been identified. The issue has not yet been reproduced or confirmed by a Kia dealer or independent service center. I have contacted Kia service personnel regarding having the vehicle inspected. I was informed that if the vehicle is inspected and the dealership cannot reproduce or identify a problem, I may be responsible for an approximately 210 diagnostic charge. The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or another independent party regarding this issue. There were no warning lights or dashboard messages indicating a problem before or when I noticed the heat

for repair a combined 38 days across two visits. The dealer initially attributed the first event to a failed alternator voltage regulator, replaced it, but the same warning codes and behavior returned on the second occasion. Crash/injury: No collision occurred; avoided through evasive braking. Speed: Highway speed (both instances). Incident description: While driving, the vehicle's dashboard illuminated all warning lights (ABS, traction control, battery, check engine, forward safety system) and the engine revved to approximately 8,000 RPM with unintended rapid acceleration. Driver had to apply hard braking to maintain control and avoid a collision. A nearly identical event occurred approximately one month earlier while driving on the highway, at which point the vehicle suddenly braked hard on its own. The vehicle has been at the dealership for repair a combined 38 days across two visits. The dealer initially attributed the first event to a failed alternator voltage regulator, replaced it, but the same warning codes and behavior returned on the second occasion. Crash/injury: No collision occurred; avoided through evasive braking. Speed: Highway speed (both instances).

stated that several unknown warning lights were flickering on and off back in April. The vehicle was taken to a dealer, where it was diagnosed that all the third-row rear seat belts had failed and needed to be replaced. The vehicle was repaired by replacing the seat belts. The manufacturer was notified of the failure and informed the contact that the seat belts were replaced and that the vehicle was ready to be picked up. The approximate failure mileage was 46,000.

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 NHTSA investigate this issue because multiple warranty repair attempts, including replacement of the display, have failed to resolve the defect.
