• 11/27/2024· ELECTRICAL SYSTEM,EXTERIOR LIGHTING

  While driving at highway speeds the exterior and interior lighting/electrial system shut down completely. My headlights shut off, as well as all electrical/lighting inside the vehicle for approximately 1 minute before turning back on as if I had turned the car off and restarted it. I have a low tire pressure warning that comes on when the car is started, and it came on again as if my car had just started, while I was still driving. This poses a safety risk to myself and other drivers depending on the headlights for visibility. The incident did not cause my vehicle to stop driving although I did break due to the sudden loss of all electrical components.

  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.

  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.

• 11/01/2024· EXTERIOR LIGHTING

  In the general design of the Kia Carnival, among other vehicles from the same manufacture (i.e. Kia Sportage) and different manufacturers (i.e. Chevy Bolt), the false taillight cluster has created a safety issue when signaling. With specific mention of the turn signals being in the lower third of the vehicle height, and not in the taillamp cluster, drivers may not ever see the turn signals from the rear of the Kia Carnival, as most drivers are looking at the large taillamp cluster, not the bottom of the rear bumper for turn signals. The poor visibility is further enhanced when combined with the height or size of other vehicles (trucks with lift-kits, large front end vehicles, or large A-pillars) or poor driving from either the vehicle mentioned, or others. Attached photo taken from the Autopian [XXX] ) as a visual reference. No warning lamps appear, and no failures occurred, as it is normal function. This is a manufacturer-created/designed problem. I believe it was done intentionally by the manufacturers to circumvent other design limitations on signaling lamps not being placed on moving surfaces such as liftgates or trunks, and thus crated a new safety issue with large false taillamp clusters that are just the dim lights for illuminating the vehicle.

  12V battery drains if the car is left unused for more than 3-4 days. Car needs to be jumped to start it up again. The issue occurred in August and I jumped it first time. It started happening again September and had a service appointment with Kia. They hard reset the software but the issue occured again every time I left the car unused for more than 3-4 days.

  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.

  I purchased brand new 2025 Kia Carnival SX less than 2 months ago and it is back at the dealership for service for the second time. First time it had an airbag light stay on the dash and the battery kept reading low voltage and would not allow us to use any features on Kia Access app such as remote start and 360 view. The dealership fixed the airbag light but did not find any electrical issues with battery after testing. The car is driven daily and after sitting for approximately 16 hours the car battery is completely dead. Tried to do a quick jump and would not crank over. I am convinced it has a parasitic draw. It is currently at second service center in hopes of a resolution. So far Kia has not been very supportive.

  The contact owns a 2025 Kia Carnival with an external Harmar Swing Away Lift, Model Number: AL100, with a mobility scooter attached. The contact stated that while driving approximately 65-70 MPH, after driving for two hours on [XXX] approaching Grand Rapids, Michigan, there was an abnormal sound coming from the vehicle, and the driver became aware that the scooter had detached. The driver was able to pull over and became aware that the scooter was in the left bound lane. Other vehicles had to swerve to avoid a crash. Another driver was able to assist with securing the scooter on the vehicle. After the failure, the contact noticed there was a four-inch gap on the lift while lying on a flat surface. The lift was taken to the installer, who confirmed that the lift was working as designed. The vehicle was not repaired. The manufacturer was contacted and referred the contact to another local dealer for further inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  The battery on this car drains despite standard operation. Battery replacements do not work and it must be jumped. Some programming aspect clearly is wrong and drains the battery when not in use. It needs to be fixed asap for safety and to avoid stranding.

  After day or two purchasing the car, I started getting notifications at the car battery was low eventually after two weeks it completely died, and I was locked out with no way to enter the car because they no longer provide a manual key in the key fob. Multiple chargers and charging with another car for hours with no luck to get the car back up once I finally did get the car open. Seems like the dealerships themselves are aware of this issue and they have no way of fixing it. They keep playing games and making circles about how they’re escalating they’re doing they’re doing that and they have not provided me with a loaner.

  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.

  Battery inexplicably drains to death. I purchased the vehicle new and, within 5 days, had battery failure. The first sign of the issue is the inability to utilize remote commands via the Kia app, receiving a message that the vehicle's battery is at a low charge of <40%. Without intervention, the battery will then drain to death.

  Brand New 2025 KIA Carnival SX model - experiencing major electrical failure within the first month (around 800 miles). There's a battery negative draw issue, and the car battery will die completely within 3 days, if not driven. Had to jump-start the car 4 times within the first month. One of the incidents had me stuck right in the middle of the road - When the battery is low, turning on the AC will result electrical system flickering, and then shutting the car down entirely. The dealership acknowledges the issue but stated no solution has been found yet.

  The battery on my new Kia Carnival 2025 SX has repeatedly died within the first few weeks of ownership. There seems to be some issue causing it to drain within 2-3 days. The battery has drained down to 4V and 7V in two of the instances. It does charge back up to full but will resume draining afterward, usually dying in 2-3 days.

  On July 19, 2024, my 2025 Kia Carnival SXP experienced a significant battery drainage issue, rendering the vehicle inoperable. The cause is currently unknown, but it seems to involve a parasitic electrical draw that drained the battery while the car was parked and turned off. This issue occurred despite no prior warning or indication of battery problems. Compounding the situation, the door locks, including the mechanical lock, were disabled, preventing access to the vehicle. Kia roadside assistance sent a locksmith, who had to jump-start the vehicle to restore operation. After the jump-start, I received warnings that multiple systems were inoperable, including critical safety and driver assistance features such as the integrated braking system, motor-driven power steering, and tire pressure monitoring system. These failures raise serious concerns about the vehicle's reliability and safety, as it became inoperable and inaccessible without warning, potentially leaving drivers and passengers stranded in dangerous situations.

• 08/09/2024· ELECTRICAL SYSTEM

  The first sign of the parasitic battery drainage is typically a warning in the Kia Access app that says the vehicle's 12v battery levels have dropped below 40% and remote functions are halted. The app will not inform you of this issue. It's only when you try to use remote functions will you find out. The more direct way of knowing about the issue is obviously discovering a dead battery which will have to be jump started. For me, this happened around 400 miles after purchasing the vehicle brand new. The vehicle is now at the dealership for servicing.

• 08/09/2024· ELECTRICAL SYSTEM

  Vehicle was purchased 7/31. Due to seeing others reporting battery drain, I began testing battery charge. I can report that my vehicle is also affected. Voltage drops significantly after just 12 hours of sitting. There’s a parasitic draw somewhere in the vehicle that is killing the batteries in EX, SX, and SX Prestige trims. I’ve purchased a jump box and I now hook it up to a battery tender every night. So far, this has prevented a dead battery, but this shouldn’t have to be done with a vehicle that isn’t yet a month old.

  Parasitic battery drain leaves car dead and unusable no matter how many jumps/replacement batteries. It happens overnight. This is WIDESPREAD - there are entire Facebook and Reddit groups with thousands of people with the issue. We need to have a fix so we can drive our cars. Driving it home from the dealership just to have it jumped or towed back to Kia and have it sit for weeks without a solution is UNACCEPTABLE. $60k for a car we can’t drive. Absolutely insane. It’s so unsafe to have a family vehicle - a minivan - have dead batteries with no warning on brand new cars. There were less than 75 miles on my car when it first happened. I had made one trip home from the dealership and one trip to the grocery store. This problem is affecting EVERYONE and Kia is about to be out of service techs and out of loaner cars with everyone in the shop until this is sorted out. Unbelievable. This is going to lead to thousands of new 2025 carnival owners going through lemon law to get cars replaced.

  Fuel evap canister leak was suspected due to very strong gas smell inside vehicle. Dealership had to change out entire fuel tank to deal with whatever was leaking. Got the car back, and the next day, the smell was back. Dealership told us not to worry about the smell, that it was normal. Drove one more time and smell was so strong that it made two adults dizzy and nauseous within five minutes. Nausea lasted multiple hours. Parked and had it towed to dealer. After multiple days, still waiting to hear back, service apartment claims they're waiting for research from Kia. Vehicle has been too dangerous to drive so sitting at dealership for nearly 30 days now, total. No warning lights or messages ever came on to notify us of the problem.
