2025 Kia Carnival complaints

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)

This is the second time, while I was driving that the car would not want to pick up speed and shuddered. The engine light came on again. And stayed on this time. I brought it back to the Kia dealer. They ran a diagnostic. They first wanted me to pay the cost. It is under the warranty. Now I am waiting for the parts and was told to not drive my car until it gets repaired. No loaner was offered. They said to drive it home and they will contact me.

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

The passenger sliding door pinch sensor did activate; but not before child’s hand was pinched in door and it almost drew blood. Door closes forcefully I have noticed compared to other minivan experiences I have with automatic doors. Quite a bit of force is needed to activate the sensor and cause the door to open back up. It needs to be more sensitive to avoid injury.

The car doesn't start after overnight, or after a period of no usage for a certain time. Push button doesn't start the engine, it takes 25-30 attempts to get it started. It keeps happening almost every day.

I was turning onto a main thoroughfare fare, and the van was slow to accelerate, Engine light briefly blinked, then went off, and then when I was on the interstate I had to pull over the van was running rough. Once I went back on the road, the steering wheel was shuddering and finally the engine smoothed out. This has happened more two other times to me.

While I was driving on a highway, my vehicles "check engine" and "batter" lights were illuminated and a warning came across the car screen that said something along the lines of "Battery Management System Failure" and then "Powertrain failure". The car was not able to accelerate by pressing the gas pedal, and the heating/cooling features within the car stopped working. I quickly changed lanes to get to the far left shoulder of the highway, putting other cars at risk of my car that was slowing down to 50mph as I was getting over. When I would press on the gas pedal, nothing would happen. The car did remain on. When the dealership received the car the next morning they conducted what they referred to as a recall, but KIA refers to it as a "Service Action" - SA617 MCU DTC Logic Improvement. This requires a simply software update, which the dealership conducted, and the car was then working just fine, with no issues that I had indicated above. The dealership was Greenway KIA of Rivergate, 1526 Gallatin Rd North, Madison, TN 37115. The warning lights in the car illuminated about 5 seconds before the car was no longer able to accelerate due to the powertrain failure. In talking about the problem with a KIA representative, it was communicated that KIA has looked into this and it didn't pose any serious problems, so they left it as a "Service Action" item, not a recall.

On 6-9-25, for the second time in the 10 weeks that I have owned my new 2025 KIA Carnival it has failed to accelerate beyond 30 MPH after pulling away from a traffic light. The vehicle displayed a warning that The Speed Limit Was 30 MPH and would not accelerate beyond that speed. The speed limit was not 30 MPH. I was able to pull onto a side street and take a photo of the warning, I took the vehicle and the photo to Boniface-Hiers KIA on 6-10-25. The dealership was not able to determine the problem but thought it could have some connection with the cruise control system. Once again I was lucky not to be rear ended by the car behind me.

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.

The "consider taking a break" feature pops up every 5 minutes when I am driving and it is beyond distracting and leads me to believe I have something wrong with my vehicle. There is no way to turn it off. Please demand that Hyundai/Kia issue a software update so I can turn this off. Thnaks!

On [XXX], while folding the second-row seatback to access the third row, as the seatback folded forward, it did so with excessive and unexpected speed, causing the seatbelt housing to swing forward and strike my wife, [XXX] , in the head with great force, [XXX] 's face. The impact caused her to momentarily lose consciousness and rendered her unable to move for nearly 30 minutes, during which she remained slumped and dazed in the seat. Fortunately, I was present to support her, preventing further harm. Although we were forced to board a scheduled flight shortly afterward, she continued to experience facial pain, disorientation, and weakness for several hours. We are deeply alarmed that such a hazard exists in a family vehicle, and that no warnings are present in the owner's manual regarding this risk. As a father of three young children, I am deeply concerned about the potential consequences of this design. This type of violent seatback movement combined with a hard, unprotected seatbelt housing could have caused even more catastrophic injuries - especially if it had happened to one of our children. My wife, [XXX] , is still emotionally shaken by the experience, and the trauma has left her fearful of operating the seats at all. This incident has had a significant impact on our family's sense of safety when using the vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On April 22, 2025 my Kia Carnival Ex would not accelerate more than 30 mph after pulling away from a traffic light. A warning appeared on the dash display saying The Speed Limit Was 30 mph and the Kia Carnival would not go beyond 30 mph. The Speed limit was Not 30 mph. I took the vehicle to the Boniface-Hiers Kia dealership on April 24, 2025. They could not find a problem but did re-set the computer for the transmission. I was very fortunate not to have been rear ended by another vehicle.

In February I was driving on the highway at the speed limit, 65MPH when a rock flew back from a truck and hit the bottom middle part of the windshield. This formed a small dime sized crack, which eventually formed into a 3FT crack that spanned from the dent, up and to the right side of the windshield. In March, while waiting for the windshield to be repaired, another rock was launched from the back of another vehicle while driving on a local road going the the speed limit, 35MPh stuck the right side of the windshield making a nickel size crack. This can be a safety concern given the fact that the windshield can crack that easily and possibly injure someone inside. I have never had a windshield break so easily on other vehicles that I have owned when such event happened. A real bad injury can occur if an object going a a bit faster or bigger were to strike the windshield and shatter it. Can this type of windshield be thick enough or the material strong enough to prevent this to continue to happen?

Bought the car after 2 months of owning it and not driving for 3 days car wouldn’t start had to charge the battery Happened again over my kids winter break didn’t drive for 2 weeks and wounds start when I went out in January 7th to star it had to charge the battery

The vehicle's battery drain after turning off and cannot restart. It can cause to stall the vehicle on road. Kia Connect sent "Our backend team has determined that a TSB ELE341 (Network Reset) is needed to refresh your vehicle’s connection to the Kia Connect servers. To resolve this, please contact your preferred official Kia dealership to schedule an appointment and mention TSB ELE341 for the network reset." Took the vehicle to a Kia dealer's service; they reset, but problem remains. I just received from Kia"Dear [XXX] , This is nothing that we can troubleshoot. You will have to wait for your appointment to have them handle the issue. Thank you Sincerely, Kia America INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

One night while driving all lights went out even panel radio too and in a couple of seconds came back to normal..a few weeks after that while driving a loud warning sound came on and the info panel turned Red when I felt a breeze my door was opened by inself

See attached document for complaint.

The contact owns a 2025 Kia Carnival. The contact stated that the vehicle was taken to a dealer for service, and the contact was informed of a washer fluid leak. The water fluid hose was replaced. However, the failure persisted. Most recently, the contact stated that the sensors failed to function as intended, and the windshield wipers would turn on independently. The vehicle was taken to an independent mechanic where it was diagnosed that the water fluid hose had failed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 600.

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 fro

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.

Brand new car and the battery is draining. Leaving the vehicle unable to start.

Battery went dead. Been at dealer 2 weeks. They are waiting to hear from Kia but nothing is being done.

The battery has died twice within 3 months. I couldn’t leave my house to collect my kids. The problem has been commented on by a dealership. No.

There seems to be a very common problem of the 2025 Kia Carnival having a battery drain issue, leaving people stranded. I had a dead battery today with only one month and 300 miles of use. Thousands have had the same experience and have discussed this on various forums.

12V Vehicle battery drained. Unable to start Vehicle.

I'm getting an alert in the car app that says low battery and will not perform any lock/unlock/start, etc features. It says the battery level is under 40%.

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.

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.

Purchased brand new, went home to put car seats in and that's when we discovered the rear sliding door did not lock. Took the vehicle in on the 7th, took until the 23rd for it to be "fixed". Picked up the vehicle came home and the car now does not lock again. Kia customer care team has been little to no help and it was suppose to be escalated to the Kia escalation team but we have yet to hear from them.

Started about a couple weeks ago. Just bought my car and my battery drained 3 nights in a row. Had to jump start it Found out some fan run, when car is off, hours after it has been parked.

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.

My bran new 2025 with 3,000 miles has a completely dead battery. The Kia roadside assistance person was unable to jump start it.

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.

Battery drain which results in vehicle not starting. There have been a series of events that ended in my Carnival not starting. Purchased new on July 6, 2024. Picked up from to Dealership July 8, 2024 and drove home. The below events started Aug 2, 2024 1. Side mirrors didn’t “wake up” when I approached with key fob 2. Truck wouldn’t close (had to manually pull shut) 3. Received app notification when attempting to lock doors through app that battery was less than 40% 4. Received dashboard warning when attempting to start 5. Lights remained on for a few seconds after attempting to start 6. Vehicle wouldn’t start 7. Turn signal - Action required via app 8. Towed to Dealership 8/5/2025 a vehicle would not start

Battery randomly died in the car overnight

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.

I've owned my new car for less than two weeks and already my car has a dead battery. I did not leave any lights on or doors opened.

As noted my many drivers in the Kia forum, I bought a 2025 Kia Carnival SX prestige only have a dead battery 2 week into ownership.

Battery drain and dead battery when parked overnight.

Vehicle sat in my garage in for 2 days and when I went to go drive, I found the vehicle was dead and had to be jumped. The vehicle currently has 370 miles on it and when I started the vehicle, it returned an error stating that the electrical system drained the battery.

Battery died after owning the car for 4 days. Kia service could not determine a cause. Parasitic drain of the battery caused car to be dead.

New 2025 Carnival SXP that has been taken back to the dealer on 2 separate occasions in the first 2 weeks of owning the vehicle. The battery has died 4 times with no obvious reason for the parasitic draw. The dealer recharged the battery once but the issue again come back just a few days later. After the second trip to the dealer, they replaced the battery, but are unable to find any other reason for the problem to have occurred.

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. Kia dealer has replaced the battery but the issue still occurred after and now it is at the dealer for the third time in a month. They confirm the issue but have not been able to identify the cause of the parisitic drain yet.

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.

After a week of owning the car the battery died over night. Was jumped by roadside and died later that day and jumped again. After the 2nd jump, the AC and air bags didn’t work. Then the check engine light came on. Kia has had my brand new carnival since July 26 with no fix.

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.

Battery constantly dead. If the vehicle is locked, can't unlock, even with provided manual key. Dies on the highway creating dangerous conditions.
