Gas/pump door actuator failed. Unable to open and put gas in car. This car is only 1.5 years old.
My [XXX] son locked himself and his [XXX] brother in the car today. The scenario which is repeatable is if the cars start button is pushed to turn on accessory power the key fob will no longer unlock the doors. My father had the key fob outside of the car, while my son scrambled up front and pushed both the start button on the car and the door lock button. Again at this point the key fob is outside the car and will not unlock the doors. The daycare had to call 911 because two children were locked inside the car. This is an unacceptable situation for a minivan. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) I have not yet brought the vehicle to a dealer, there are no warning lights on the vehicle and the key fob is working and has power.

Gas door outside cover would not open which makes it impossible to pump gas. Dealership removed door to enable the ability to pump gas. This then disables the safety feature that keeps the van door from sliding open which a rear passenger may mistakenly open the door and the gas pump hose would be knocked off. if Dealership opens the door to the gas area, and leaves the door to the gas cover ajar slightly to enable the ability to pump gas, this causes an issue if the door is mistakenly opened by a rear passenger, there is no clearance and the door to the gas area would be ripped off. One incident Dec 2023, another incident May 2025
The windshield started cracking while the car was parked and continued cracking over the next week. The crack now runs from the center top, 3/4 of the way across the driver's side
The rails in the middle row where the seats connect to, get extremely hot to the point where it is very hot to touch. This is a safety issue that could potentially cause a fire and/or burn my children’s’ feet. It doesn’t matter if the car has been driven for a short period of time or on a long trip, regardless the rails get very hot
The metal rails on the floor where the seats slide are very hot and we are afraid it will run our children. It is more in the center near the second row.
The sliding power doors do not reverse when hitting a person or object. You have to use excessive force to get them to reverse and only some of the time do they even reverse. I have taken this to the dealership and they said they would contact me within 48 hours with an update but it's been a month and in spite of me attempting to contact them for a follow up they have not returned calls or emails. Safety of myself and others have been put at risk when the door is closed it does not stop and will crush whatever is in the door. Dealer was able to reproduce the problem about half of the time. Occasionally, if you hit the door in a specific spot, it might reverse but when an actual person stands in the door it does not reverse. No warning lights or messages occur I purchased the Carnival July 1 of 2022 and was not aware at the time of the sliding door problem. It wasn't until I read of others having the issue that I tested mine. I was honestly shocked that the doors in most cases did not reverse. I've tested it multiple times and I've had to get out of the way when in spite of using a lot of force it didn't reverse. I also have a 2004 Honda Odyssey that I've had for almost 20 years and this door works perfectly. Reverses with even a minor resistance. I expected all minivans to perform the same way. There are multiple incidents found online where these doors have crushed people. I'm aware of a recall just released but this does NOT fix the issue! It only adds 2 beeps and slows down the door. This is unacceptable in a real life situation so this "recall" is not acceptable. I realize KIA does not want to pay to have these doors fixed but when a child dies or suffers a severe injury they will be forced to.
I have an issue that involves the metal railings in the center of the vehicle (on the floor) to get hot enough to burn and blister you. I filed a complaint with Kia which opened a case. I also took my vehicle in and this issue was verified by their mechanic. I was assigned a case number and after the employee on my case spoke with the enginer team it was determined that the only option for me was to purchase mats to cover the metal railings. I purchased both all weather and fabric mats when i purchased the vehicle. these mats do not cover the railing nor would you want them to. it would prevent the seats from moving forward and back and it would also be a fire risk. I have tried to find a solution with kia with no success. There are other forums of people complaining of the same issue such as this one https:// [XXX] I just purchased my car brand new and Kia has put me in a position to just deal with these safety issues. Besides mats that i already have the suggestion was to just not touch the rails that are on the floor where you put your feet. I put 10,000 down on a brand-new vehicle because i had the intentions of keeping it long term. now im in a position where I have to look for a safer vehicle with no help from KIA. This complaint may not help me but maybe it can help someone else. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
Rear sliding door safety sensors not working properly. Doors do not stop closing unless excessive force is applied by an adult before the sensors start working. Young children would not be able to stop the door from closing on them and likely would get hurt because of it.
today while I was driving my sunroof shattered, big explosion, luckily my sunshade was close and not to many vehicles were around me. I call dealer, they didn't want to hear it and told me to call my insurance !!??? My car is barely 2 month old???
Very small rock hit windshield and cracked entire windshield; crack spread quickly and has continued to progress
Sliding door shut on toddlers fingers, the safety mechanism for the door to open failed.
