My 2025 Kia Carnival Hybrid was purchased new in January 2025. The problem began almost immediately, with the vehicle first presented to an authorized Kia dealer for this condition at only 810 miles. The vehicle repeatedly and unpredictably enters reduced-power or “limp mode,” causing a sudden loss of normal acceleration and limiting it to approximately 35 mph. This creates a serious safety risk on highways, while merging, crossing intersections, or whenever acceleration is needed to respond to traffic. Equally concerning, the vehicle does not consistently display a warning or retain a hard diagnostic error code when the loss of power occurs. Sometimes a check-engine light or “Check Hybrid S
October 20, 2026Unknown or Other1 injury
On XXX, at about 4:50 PM, my [XXX] son’s hand was caught in the left (driver-side) power sliding door of our 2025 Kia Carnival Hybrid (VIN [XXX]; approximately 30,000 miles). The power sliding door was enabled and the door-close function was activated using the interior button. The door did not stop or automatically reverse. It closed completely and stayed latched on his finger. I had to open the door manually to release his hand. An X-ray confirmed a broken finger. I am concerned that the powered sliding door’s obstruction detection and reversal features did not prevent this crushing injury. I request that NHTSA review this incident as a potential child-injury motor vehicle safety defect. I

In May 2026, after driving through a heavy rainstorm on the highway, the car suddenly cut off cruise control and showed multiple warning lights (for most, if not all assistance systems) and an error message that was some version of "check hybrid system." When searching the code it seemed to be related to an electrical short in the hybrid system. I had no electric power to the engine, but the gas functionality still sort of worked, so I could drive, but there was a 2-3 second delay between pushing the gas pedal and getting any acceleration, and said acceleration was minimal. This occurred at 70+ mph on a busy highway, so the sudden lack of acceleration and control was alarming and put us and

The contact owns a 2025 Kia Carnival. The contact stated that her child screamed when the rear passenger’s side sliding door failed to detect the child's hand and closed on the child’s hand on four separate occasions. The contact pressed the rear sliding door button to release the door from the child's hand. The failure resulted in a door indentation across the child's four fingers, but no medical attention was received. Prior to the failure, the vehicle was taken to the dealer for the front driver's side door that failed to latch unless the door was slammed closed. The dealer previously inspected the doors, but the vehicle was not diagnosed or repaired. The manufacturer was notified of the
