2023 Kia Carnival Service and Repair Manual

Known issues on the 2023 Carnival. Four recalls are on federal record for this model year. The first concerns the power sliding doors on certain 2023 Carnivals: the auto-reverse feature may not activate in all situations, and a power sliding door that does not auto-reverse can close on an occupant. The second covers the roof molding, which may loosen and detach — a detached roof molding can create a road hazard for other vehicles, increasing the risk of a crash. The third applies to Carnivals equipped with a tow hitch harness installed as original equipment, or purchased as an accessory through a Kia dealership; a fire while parked or driving can increase the risk of injury. The fourth sits in the fuel system: fuel may leak at the pipe connection between the fuel pipe and fuel rail, and a fuel leak increases the risk of a fire. Owners submitted 57 complaints for the year and Kia has issued 58 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you are verifying sliding-door auto-reverse operation, inspecting the fuel-rail pipe connection, or working through a routine service, it keeps you on Kia’s own procedure and the correct specification for your 2023 Carnival.

ABS was activating inappropriately creating a grinding/pulsating noise while I was attempting to stop at a light. The vehicle did slow down but despite the completely dry road service and sufficient stopping distance, the vehicle never came to a stop and ran into the vehicle in front of me. The vehicle is currently in the autobody shop to be repaired as it is not drivable (leaking fluids). I will be contacting my insurance company and an independent service center shortly to have it inspect
Passenger side sliding door periodically gets stuck trying to open or close. My 3 year olds finger got stuck in the closed position of the sliding door and we could not get the door open immediately because of the faulty door periodically getting stuck.
Daughter presses the button on the inside of the van. She didn't move her hand soon enough out of the way for the door to close. The door closed on her hand, she had to press the button open from the door closing on her thumb. She came balling her eyes out to me. Her thumb swelled 3 x's as big. The sensor should be way more sensitive like a garage door opener.
The metal rails where the middle seat of the middle row is located occasionally gets too hot to touch. My daughter who was sleep had her sandals off. She woke up because her foot was hot. Shortly after her toe blistered. You won’t notice it if you have shoes on. It has happened while we were traveling and it happens when we’re just idle.
The driver’s side sliding door was closing and crushed my wife between the door and B pillar. It did not retract upon encountering the resistance of my wife’s body, and continued to close. She has bruising on her arm, and shoulder pain. When submitting this report on the NHTSA website, there is a recall for this exact issue. We have not had the vehicle examined as it is a holiday weekend, and the dealer is closed. Medical attention will be pursued if the pain and bruising does not subside.
Our Carnival had the SC266 recall repair done on July 3rd, 2023, at 3074 miles. Then our [XXX] daughter was injured as a result of the safety function not working and the door closed without any chimes. [XXX] (my spouse) is a cardiac nurse at our local hospital, and I have combat medical training, so we took care of the minor injury. Her small hand was spared the devastation a larger one would suffer. The dealership is pretending it’s unreproducible (even though I supplied them with video evi
The side sliding (rear) doors do not stop when there is an object in between. Even when you put heavy force (this is in some angles), the door continues to close. With mild force, the door just refuses to recognize and closes out. It is a big safety concern with small children, since if the force applied by adults is not enough, then any force the child would apply is definitely not going to stop the door from closing.
The door closing automation applies excessive force before the safety function engages to re-open. This poses a high risk to children and small adults with narrow limbs and/or the fingers of any aged person. On January 11, 2023, my 4 year old's hand was closed in the door without the door stopping or re-opening. This resulted in deep lacerations to his fingers and swelling necessitating emergency room medicine and imaging to eliminate potential of fracture. I tested this morning with the doo
Kia Carnival's 2nd row seta pretensioners are not working. In the vent of suddent breaks, the seat belts are not latching, and hence not holding the kids in the seats. We have faced this issue several times. Once my daughter came out of seat completely, since the seat belt didn't latch the belt. We took to the dealership(Kings Kia, Mason, OH), the technician agreed, there is problem with 2 seats, however, there is problem with all 3 seats. The dealership said they are still waiting for K

On August 23, 2025, I purchased a certified pre-owned Kia Carnival. Within hours, the vehicle had a severe fuel leak that produced a strong gasoline odor. Driving it made me sick, and I feared for the safety of my three children in the vehicle. A Kia technician later confirmed a crossover fuel line leak so severe that he became ill while inspecting it and feared the vehicle could explode. Even after repair, the gas odor persisted. This vehicle was sold to me in unsafe condition, and I believe th
The contact owns a 2023 Kia Carnival. The contact stated there was oil leaking from the vehicle onto the floorboard nearby the brake pedal.
