2025 KIA CARNIVAL Unknown Or Other Problems

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.

Vehicle Malfunction Report What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle's transmission and/or gear shifter system has failed to function as intended. When the gear shifter is set to "Reverse," the transmission has repeatedly shifted into "Drive" or "Neutral" instead. Concurrently, the vehicle's electronic backup camera system and audible sensor beep activate, indicating that the vehicle believes it is in reverse. The van is available for inspection upon request. How was your safety or the safety of others put at risk? My safety and the safety of others were put at risk on multiple occasions due to the vehicle shifting into the wrong gear. This has caused the van to unexpectedly lurch forward when I intended to back up. I have nearly collided with other parked vehicles and my garage door between 10 to 20 times. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem has not yet been reproduced or confirmed by a dealer or service center, but it has occurred on numerous occasions and is a confirmed issue by the driver. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? To date, the vehicle and its components have not been inspected by the manufacturer, police, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or messages displayed prior to the problem occurring. The primary symptoms of the malfunction are the vehicle shifting into "Drive" or "Neutral" instead of "Reverse," while the backup camera and an audible beep are active. These symptoms began almost immediately after the vehicle was purchased.

On two separate occasions, [XXX] and [XXX], I received emails from Kia Connect giving me a 12-Volt Battery Discharge Warning. I have the car out at the local dealership right now and they say there is nothing wrong with the battery but they are replacing it. I have noticed online multiple owners are complaining of the same issue and Kia has had a recall of a similar issue with a different model of car in the past.

When I was trying to accelerate over 30 MPH I got a driver assistance warning 10 warning lights came on so I pulled over and once I put the car into park it would no longer shift into drive.

Battery randomly dies.

On or around [XXX] the rear occupant sensor warning light came on. We scheduled a service appointment with the dealership for 7/15/25 at 7:00 a.m.. We were informed later that morning that it was a defective module that could affect the air bags and it wasn’t safe to drive the car. It is 7/26/25 and we still wait on the part. Yesterday we were told by the service department that they didn’t know when the part would be available, it is back ordered due to the number of vehicles with the same issue. While our car waits at the dealership we got an email from Kia Connect giving us a 12 volt battery discharge warning. We don’t know if this is related or not but when looking online we found several people with that same problem as well. Our mechanic agreed that the 12 volt battery should not be discharging that fast due to just not being driven. The car sits at Russ Darrow Kia in Madison WI where parts and other information should be available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The floor behind the passenger side gets very hot and you cannot touch where the tracks for the seat are with your hand for risk of pain. This occurs for the middle passenger behind the front passenger and also the third row floor on the passenger side. Also the temperature in the cabin is substantially warmer due to this heat

Carnival came with DVD players for kids in the back seat. It contains a volume control that can be controlled by the child. The child at any point can blast the stereo insanely high which can distract the driver and could cause an accident. This needs to be recalled immediately. There is no reason for the sound to be able to be blasted that loud. Then if it happens, there is no fast way to turn it down which causes the driver to fumble. Please look into this immediately as it can effect any owner.

On [XXX], I was in a busy parking garage holding my [XXX] child on my hip and pushing the stroller, with my [XXX] safely procured inside, as I approached my Kia Carnival 2025 to load the children and depart. To avoid active traffic while allowing enough room for the automatic doors to open safely, I moved as close to the Kia Carnival as possible with my [XXX] and infant in the stroller, engaging the safety breaks of the stroller. Due to the tight space, I underestimated the length the door needed to fully open by approximately 3 inches; this should not have been an issue as there is a sensor in the door that stops when it senses any object in its way. However, the sensor failed. The door did not stop when it came in to contact with the stroller that had my [XXX] baby in it. With the safety brakes engaged to prevent the stroller from rolling away, I desperately tried to drag away the locked stroller as quickly as possible. The door hit the stroller, continuing to open regardless of the object (my infant in her stroller) in the way, hooking the stroller on the lip of the door and pushing it up and over. If I did not have my hand on the stroller and acted so quickly, my daughter could have been seriously injured or worse. If the stroller had been facing the other way, I fear what would have happened. In addition, had it been my toddler standing there, she would have been crushed. I also endured bodily injury, physical strain, and mental anguish while keeping my children safe from this malfunction. I was in shock by the pure fear created by that situation. It was devastating. The door will not physically stop opening if you try to pull on it. The sensor does not work in detecting any body when opening. It needs physical force exerted against it, the size of an adult male to kick in. It is negligent. (Kia was already sued for this in previous models- they know it’s an issue!)

At around 200 miles, I could no longer gain access to my vehicle via via both keys and the Kia app. My vehicle has been sitting at the dealership for 20 days without a resolution and little communication from Kia
