2025 Kia Carnival Complaints

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.

The rear sliding door on the driver's side was not locking. I took it to the dealership and they have replaced the actuator, the wiring harness, and the IPM power module. None of this has fixed it. We now have a Kia special mechanic coming to [XXX] to take a look at it. I was told there are 19 other vehicles in [XXX] with the same issue.

The contact owns a 2025 Kia Carnival. The contact stated that while parked in a bank drive-thru, the contact's son mentioned that his seat belt was stuck. The contact parked the vehicle in a parking spot and attempted to remove the seat belt; however, the seat belt retracted tightly around his abdomen as the lower half of his body was turning blue, requiring the contact's husband to cut the seat belt. The contact mentioned that it was discovered that all seat belts located in the rear row seats failed. The contact 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.

The contact owns a Chico Car Seat, Model Type: Fit 360, Model Number: 08087216240070, Manufactured Date: December 2025, and used in a 2025 Kia Carnival. The contact stated that the magnetic chest clip failed to remain closed as needed. The manufacturer was contacted and provided a replacement chest clip. The manufacturer stated that the chest clip operated as designed and was designed to come apart. The contact was concerned that the replacement chest clip was defective, and in the event of crash the car seat would not perform as intended. The contact requested a nonmagnetic chest clip from the manufacturer.

**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...
