2023 Kia Carnival Problems & Owner Complaints

Unknown Or Other 22 3 injury

“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 evidence to the contrary), and Kia Corporate (case # XXX) doesn’t appear any more likely to help. I rep…”

“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.”

“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.”

“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.”

“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.”

“Unknown. My vehicle has cut off in the middle of traffic several times. Another incident was when my vehicle was shaking uncontrollably and couldn't go over 40. The check engine light never comes on. One dealership looked at it and said nothing was wrong even though one of the techs heard the vehicle. They said because the check engine light wasn't on that there was nothing that they could do. Took it to the kia dealership in Huntsville. They know something is wrong but because no check engine light or codes. They don't know where the problem is . My main issue is when something is wron…”

Chest Clip 2

“Unknown as to what exactly happened, but my husband put my daughter in her car seat buckled her and was just fine. We arrived to our destination no more than 15 minutes later and her chest clip buckle had busted apart. I do have video of the chest clip and how it was apart, however, as soon as I get the new piece and I will not have it to show due to needing the car seat. I do have video of the incident right after I noticed it and other videos showing the parts and pieces. My daughter ended up having the pieces that you press together to unlock the magnetic chest clip apart in her mouth. Th…”

“The car seat harness fails to stay engaged in a safe and secure position. When tightened to the correct position it becomes loose. I contacted Nuna and they advised I should clean the harness adjuster button from debris but I did that and the harness is still coming loose. I don’t know how many times my children have been transported while wearing this faulty harness over time since purchasing our seats in 2021 but we are in our vehicle daily so my guess is upwards of 100’s of times. The manufacturer refuses to take accountability and recommends we wait indefinitely for a new car seat fabric c…”

“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.

Forward Collision Avoidance 1

“The vehicle throws a forward collision warning and then suddenly brakes to slow down while driving with no road hazard in front. This occurs about once every 10 days. This is a safety hazard because the forward collision warning has to be turned off every time the car is turned on. It will not stay off. During sudden braking, an accident may occur behind the vehicle. We have left the car at the dealer for 3 days while paying for a rental car and they said they could not reproduce the error. I have contacted KIA through their website about a week ago and have received no response. I have vi…”

Fuel/Propulsion System 1

“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 this may represent a larger safety issue that needs investigation.”

Service Brakes 1 1 crash

“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 inspected. I will also be contacting Kia America, Inc.. There were no warning lamps or symptoms of the pr…”
