POWER TRAIN
URGENT SAFETY CONCERN/ISSUE On [XXX], while driving my 2026 Kia Carnival Hybrid SX Prestige, it lost all power without warning, leaving me unable to accelerate or control the vehicle. This created an unsafe situation as I was traveling at 40 mph when all power was lost. What happened to me was a serious safety hazard. The vehicle was brand new with only 1351 miles at the time. Several warning lights came on including the hybrid system warning light. The vehicle was not drivable; there was no power at all. I had to tow the vehicle to a Kia dealer where it took 17 days to repair with a new power module. On [XXX], (after the vehicle was repaired), I was driving the vehicle when the POWER alert flashed on the dashboard. I did not lose total power yet, but the literature advises that I take the vehicle into the dealership asap to have them look into the Power warning light coming on. I have an appointment on September 18, 2025. I have reported my issue to Kia customer service, and the dealership is aware of what is going on. I believe what is happening, (the abrupt loss of total power while driving) may be a widespread defect affecting the Carnival hybrid system in 2025 and 2026 model years. This is a serious safety issue that need corrected before someone is killed or seriously injured. Total loss of power at 40 mph or more cannot be permitted to happen. There should be some sort of safety bypass whereby the gas engine totally engages to the exclusion of the hybrid system, so total power is NOT lost at High speeds.

ELECTRICAL SYSTEM
I went to use my vehicle horn when another driver pulled out in front of me and the sound was way off...it sounded like a clown horn. I subsequently took to the Kia dealer where they diagnosed that one of the horns failed and it was replaced under an extended warranty with a deductible payment. The failure of the horn compromised my safety and the other driver's as the other driver may not have heard my warning that my vehicle was where it was. There was no warning that the horn failed until I went to use it.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY
The contact owns a 2025 Kia Carnival. The contact stated that on several occasions the vehicle failed to start due to the 24-Volt battery failure. The vehicle was jump-started and operated normally, but the failure reoccurred. Additionally, the contact indicated that the emergency key failed to open the doors of the vehicle after the battery malfunction. A locksmith was called to the scene to open the doors. The cause of the failures was not yet determined. The local dealer and manufacturer were notified of the failures. The failure mileage was 600.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
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.

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM, POWER TRAIN
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.

ELECTRICAL SYSTEM, ENGINE
While driving, the vehicle intermittently fails to accelerate when the accelerator is pressed; it will only coast at about 30 mph. At the same time, the hybrid battery indicator shows a low charge that continues to drop rather than recharge. The “Check Hybrid System – Stop Safely” warning also comes on. This recurring loss of propulsion creates a significant safety risk because we cannot reach or maintain normal traffic speeds. We have taken the van to our local Kia dealership about this situation on two separate occasions; the first time it was reported no faults found bc they couldn’t replicate the problem. I was told there was a recall and it should fix the problem. The second time I was able to capture video of it happening multiple times to show the service technician. I was told it was something about the air intake system not being properly positioned. Now that the car is out of the shop, about two weeks later I’m experiencing issues where I’m unable to switch gears properly on multiple occasions as well. It’s been one thing after the next since I’ve gotten this vehicle.

The power sliding door does not reverse when an object is in its path. The door closed on my sons body. He was okay we were able to pull the handle to make it open again but it did not stop on its own. Another instance the door did not stop closing when a toy went into the door. The door just crunched the toy and shut while beeping.

ENGINE, VEHICLE SPEED CONTROL, POWER TRAIN
The hybrid car intermittently switches into EV mode after coming to a complete stop (e.g., at a traffic signal or after briefly stopping to pick up my child). When this happens, the vehicle does not accelerate properly once back on the road and feels stuck in EV mode, unable to accelerate beyond ~45 mph. This creates a safety concern when merging or crossing intersections.

The Kia Carnival was parked a slight decline and when the button to close the passenger sliding door the door closed rapidly like a guillotine. Thankfully no children or body part were in the path of the door because it would have severely damaged them. After it closed rapidly the door was unable to be opened. The dealership is still working on the Carnival and it has been over 3 weeks and they said they have never seen anything like this since it tore off a bolt in the body frame and caused damage to the body frame and they were unable to open it. Still don't have a timeline for repair. Also concerned it may happen to the other side and the safety issues around it.

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.

Side passenger doors do not stop when something is in the way when the automatic door close feature is used. We tried holding a hot dog and large piece of celery in the way of the door as it closed. The sensor did not detect either item and broke them both in two. If this was a human limb, finger, neck or other body part, great bodily harm would occur.

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.

VEHICLE SPEED CONTROL, POWER TRAIN
When traveling on the highway, the vehicle would not shift into a higher gear limiting the control of the vehicle to accelerate to the flow of traffic. The transmission would not shift for approximately 1/4 of a mile and was stuck at a max speed of ~35 mph and it would not accelerate. This loss of control almost caused an accident and put my family and self at extreme risk. Eventually the vehicle did finally shift gears allowing us to accelerate with the flow of traffic (60mph) This issue with a delay in shifting gears has intermittently happened on prior occasion when accelerating from a full stop, however, this was the first time it happened at an accelerated speed. The vehicle is not safe to operate and was towed to a service center; however, the issue is intermittent and not easily reproducible -- making it even more dangerous as you do not know when it will happen next.

While driving at random times, there is no acceleration while pressing the gas pedal. The battery shows low charge and gradually goes down instead of up. Sometimes the “check hybrid system stop safely” warning light comes on. Our safety was put at risk because it has happened while trying to merge on to the freeway or when there is no shoulder or area to stop safely. Since we can only glide no more than 30 mph we can easily cause an accident if we are not able to exit the road safely. We have taken the van in for inspection to two different Kia dealers and they are not able to find anything wrong. We were stranded 2 hours from home and had to take an uber because the van would not accelerate fast enough to drive on the freeway. The check hybrid system light has turned on at least 3 times but the dealership says there is no record of any warning lights turning on. We took a picture of the light while it was on the last time. This problem has occurred over 8 times putting our lives at risk.

Driver assistance system. This system monitors vehicle variables and unnecessarily SOUNDS A WARNING to take a COFFEE BREAK!! Here is the issue. When driving I need critical warning information. It is distracting while driving to be alerted to a COFFEE BREAK warning. PLEASE direct KIA to enable drivers to TURN OFF this feature. Every 10 minutes I am getting a warning and the warning is completely unrelated to driver status or restfullness. Driver assistance systems should be able to have HUMAN control. This is an assistance system, not a safety system. Please direct KIA issue as system update to allow human control of driver assistance.
