2025 Kia Carnival

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.

Passenger sliding door failed to detect my son and closed completely on his arm. The doors will push the kids and don’t detect even adults at times. He now has a buckle fracture that they are concerned is a full fracture in both bone on his forearm. He is [XXX] old.

I am writing concerning the Driver Attention Warning system and how it seems to be way too sensitive and when it keeps going off, trying to see what is causing this issue. This seems to be creating more distractions than it is designed to solve. From my understanding Kia through a software update removed any sensitivity adjustments which makes this problematic.

Today, my young daughter pressed the button on the inside of the door to close the sliding door. Her hand was still in the way and the door did not stop. Part of her hand was completely closed in the door and she screamed and cried in excruciating pain. Right away I noticed bruising and took her to the ER for an X-ray. Since she is so young, her bones are very pliable and thank goodness the X-ray showed no fracture, just bruising and swelling. The sliding door has previously not stopped for my older daughters as well. This is a major safety issue.

The component that has failed are both Rear Entertainment System (RES). The vehicle is at the dealership and they are unable to determine the cause hence the vehicle is at the dealership for an additional day. There were no warning lamps, messages or other systems of the problem prior to the failure. The failure happened Oct. 5, 2025. I also called KIA Connect Center on Oct. 9, 2025 and they recommended a soft reset which did not resolve the issue hence finally able to take it to the dealership on Nov. 24, 2025.

The 12-volt battery fully discharges and leaves the vehicle inoperable ONLY when parked in my attached townhouse garage (overnight or 1–3 days). The vehicle starts and runs normally when parked elsewhere (work, airport, etc.) for the same duration. Symptoms: No warning lights prior to failure Dashboard completely dark; no power to doors, lights, or start button Requires jump-start or tow

I WAS DRIVING TO WORK AND HEARD A LOUD NOISE, THEN THE SOUND OF GLASS SHATTERING. I PULLED OVER AND LOOKED AT ALL MY WINDOWS AND DIDNT SEE ANYTHING. I CONTINUTED DRIVING AND I COULD HEAR AIR COMING FROM ABOVE, WHILE AT A REDLIGHT I STARTED OPENING THE SUNROOF COVER AND SAW GLASS. I IMMEDIATELY CLOSED IT AND RETURNED HOME AND GOT MY OTHER VEHICLE. THERE WAS NO CARS IN FRONT OF ME AND NOTHING ABOVE ME.

I live in Alabama. Temperature here is 34 degrees so far in the morning. My check engine light is on. I have taken it in and had diagnostics and they can't find a code or code history. My heat and AC do not work properly if the ambient temperature on the cluster doesn't show up or is not correct. 72 degrees when it's not working right will run you out of the car it's so hot. The cluster currently says it's -15 degrees outside and has the snowflake beside it. I am scheduled bc they are booked out at the dealership to have diagnostics run on 11/14. I don't know if it is wiring, ambient temperature sensor, max air sensor, HVAC module (dealership had previously cleared water out of the module and then replaced the module, initially when they couldn't find the problem they disconnected the battery and reconnected to reset and clear the code). The dealership in Auburn Al has addressed all the issues and done all the services, updates, and trouble shooting. I'm having to run three different temps in the car and crack the windows when I need heat and AC just crack the windows and adjust the three temps again. I feel like I'm just getting a quick fix each time I go instead of the problem being resolved for good. This has been an ongoing issue especially when the temperature changes (seasons) or fluctuates (throughout the day). I've listed below the most recent start date. I would have to contact that dealership to get the exact timeframe that it ALL started.

The 2025 Kia Carnivals have a safety systems that prompts the driver to, "Take and coffee break". The system cannot be turned off and is extremely distracting. The system prompts the driver even if the adaptive cruise control is turned off. I called Kia and they told me to take the vehicle to the dealer. The dealer was not able to turn the computer nag off either. The car makes a noise and the prompt flashes at the driver every few miles. This happens when traveling at highway speeds and in traffic. The driver has to look down from the road to see what the noise is and is greeted with the infuriating "Take a coffee break" message. It is extremely distracting and annoying to the point it induces road rage. The NTSB needs to investigate this system and require manufacturers to either allow owners to turn it off or do not include this feature in their vehicles. The next question is irrelevant because this happens on almost every highway drive. It is not a one time occurrence.
