2025 Kia Carnival: Recalls, Complaints & California Lemon Law

Due to soy-insulated wiring used in wiring harnesses, rodents are attracted to the wiring components in the engine bay. Even using deterrents doesn't see to affect them. What started as a simple check engine light for what was assumed to be a faulty sensor turned into a total wiring harness replacement. Without knowing that the wiring provided an added risk to damage from external factors, there was no need to check any of the wiring. If the check engine light didn't come on, it was possible that total power loss to the vehicle could've occurred at any time, due to the various wires damaged by the rodents. We were driving on the freeway at the time when the initial check engine light came on, and a loss of power while going 65 mph could've been devastating to both our family and other drivers on the road at the same time. Insurance confirmed that the cause of the wiring damage was related to the rodents being attracted to the material, and at the dealership there were at least 2 other cars needing full wiring harness replacements due to similar damage from rodents.

I am submitting a safety-related complaint regarding my 2025 Kia Carnival with approximately 4,000 miles. The vehicle experienced an electronic system failure that required diagnosis by an authorized Kia dealership. The dealer has informed me that the issue is due to a failed Body Domain Controller (BDC), which must be replaced. The vehicle is currently not safe or suitable for normal operation and will remain at the dealership for at up to one week, with the possibility of a longer delay depending on parts availability. The vehicle has very low mileage and has been maintained normally. A failure of a central body control module at under 4,000 miles raises serious concerns regarding vehicle reliability, quality, and potential safety implications, as the Body Domain Controller manages multiple critical vehicle systems. Additionally, during this repair period, the dealership has provided only a Kia K5 sedan as a loaner vehicle. This is not a comparable replacement to a Kia Carnival minivan and does not adequately meet the functional needs of my household, which relies on the Carnival’s passenger and cargo capacity. While this is not a safety issue itself, it compounds the impact of the vehicle failure. I am concerned that this failure may indicate a broader defect affecting other 2025 Kia Carnival vehicles and request that NHTSA review this issue for potential investigation, recall consideration, or further monitoring.

12v Battery died 2 times first on 12/26 then on 1/25. We had to call in roadside assistance for jump start. This was reported to Kia Dublin and Kia Manteca in California. Kia Dublin ran the diagnostics and couldnt find anything. Kia Manteca later found the battery logs showing issues. But said it could have been related to the HVAC recall which is now fixed. But the problem re-occured. This is a brand new vehicle less than 1 year old, still unders warranty. Have reported this to Kia customer care as well. Kia Customer Care Case#XXX So far, we have had the following issues: 1. The front passenger seat recliner stopped working. Kia Manteca replaced the seat frame under warranty. 2. Both rear entertainment screens stopped working. Kia Dublin has ordered them under warranty. Replacement planned for 1/26. 3. Battery died 2 times, luckily car was in the garage we were not stranded anywhere outside. But its frustrating how the new car is not working as expected and stalls so frequently.

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.

Allegedly reported: 1 injury (as reported to NHTSA). NHTSA #11723970

The car fails to accelerate sporadically, occurred multiple times in a 2 day period. First time was getting on an on ramp to the highway, I got up to 55 MPH then couldn’t accelerate anymore even with my foot on the gas. I dropped down to 32 MPH and had to merge onto the highway at that speed. I had a semi fly up behind me and swerve around me because I was going so slow, I’m thankful there wasn’t an accident, I had 6 passengers and it could’ve been a very bad situation. It finally gave some acceleration but even then later gave out when driving on the highway. I went from 70 to 53 MPH before I could accelerate again. Other times it happens I was on a road going 35 MPH and it wouldn’t accelerate anymore, dropped down to 26 MPH. I can only coast and pressing the gas just revs the engine, going up to 4000 RPM. It only happens when already driving, not from a dead stop (at least so far). This has happened in all 3 driving modes, Eco (happened the most in this mode), Sport and Smart mode. This has to be addressed and fixed, I’m nervous to drive the car or have my family ride in it. There were no warning lights showing and the diagnostics are stating normal. I’m taking it to a dealership today. The one detail I noticed that happened consistently was the car seemed to be stuck in a mode not being able to determine if it’s in charging, electric or hybrid mode and tries to combine them. There’s a graphic on the display that shows the power either coming from the battery to the front wheels OR from the front wheels to the battery, never arrows both ways. When this happened, there were arrows going both ways from the batteries to the front wheels and from the front wheels to the battery at the same time. Finally when I could accelerate again, the arrows were going one direction. Please report this and make Kia fix this terrible safety issue.

I was stopped in in the left turn lane with my right foot on the brake pedal. Suddenly the car began to rapidly move forward. I jammed my right foot down and stopped the car, avoiding an accident.

NHTSA #11695410

My carnival is only a few weeks old. The first week of driving I was on the freeway and I was suddenly unable to accelerate. The started slowing down and pressing the gas did nothing. I was able to get off to the side of the freeway where I turned off the car. Once the car was back on it was fine. However later in the drive while street driving the same thing happened and I again had to pull over and turn off then on the car again. I explained this to the dealership on the phone thinking it may be an issue with the mode I was driving in. The dealer told me he had heard of this before and I need to switch modes. I have since switched to smart mode where it goes in and out from economy to sport and it failed to accelerate again twice this weekend where I had to pull over and turn off the car. I have an appointment with the dealer however I have no seem posts and complaints of others with this same issue and no resolution. This is extremely dangerous.

NHTSA #11657366

Van made a loud pop noise and lost power. The HSG belt tensioner spring fell off it's seat loosing tension on the HSG belt. Was unsafe but luckily it happened before getting on the freeway, and coasted into a parking lot. Yes, it's at the dealership getting a replacement tensioner and belt. I believe so. No notification prior to failure, it was sudden.

NHTSA #11744526

Carnival was working fine then, without warning, I was unable to accelerate. Had entered highway and reached a maximum speed around 30 mph in a 55 mph zone. Pedal fully depressed and zero acceleration, dashboard read "check hybrid system, stop safely". Tried changing driving modes to no effect. Lots of cars speeding past as I pulled to the side to restart the vehicle, then it worked again without issue. Happened one other time, similar circumstances and results.

NHTSA #11734666

Despite being only 18 months old with under 26,000 miles, the vehicle suffered a catastrophic failure with no prior dashboard warnings. While driving at highway speeds, loud cracking noises occurred while the engine was running, though we were able to pull off safely. The incident resulted in a burning smell, fumes, and rapid battery drain; subsequent inspection revealed a sheared tensioner spring and a critical VDCU diagnostic code (P1A7795), indicating a "Check Generator Belt" error and a major hybrid power control system failure.

NHTSA #11735023

I am filing this complaint to report a recurring, life-threatening safety defect in my 2025 Kia Carnival Hybrid involving the battery and hybrid propulsion system. This defect has occurred twice, and despite dealer repair attempts, it has not been resolved. On both occasions, while the vehicle was in operation, the hybrid system failed without warning. The vehicle displayed a hybrid system failure alert, lost the ability to accelerate normally, and became unable to maintain safe driving speeds. On the most recent occurrence, the sudden and unexpected loss of vehicle power created an immediate risk of collision. The vehicle’s failure while in traffic nearly resulted in a serious crash. I was driving with passengers at the time. The vehicle was taken to an authorized Kia dealership for repair following each incident. The same defect has now recurred after the first repair was completed, demonstrating that the underlying cause has not been identified or corrected. This defect substantially impairs the safety of the vehicle. The sudden loss of hybrid system function and propulsion while driving at road speed creates a direct and serious risk of accident, injury, or death to the vehicle’s occupants and to other drivers on the road. I am a [XXX] resident and am aware that this defect is not isolated to my vehicle. Numerous other 2025 Kia Carnival Hybrid owners have filed similar NHTSA complaints regarding battery failure and sudden loss of acceleration. I urge the NHTSA to open a formal investigation into this defect and to require Kia Motors America to issue a safety recall. I am currently too frightened to operate this vehicle and request urgent attention to this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

NHTSA #11741345

While driving around, the van will go into "limp mode" effecting my speed and acceleration. Then the battery will become drained and the car alarms me to "Check Hybrid System. Stop safely." It seems the hybrid system fails to switch from battery to engine when the battery gets too low, creating the alert. While the vehicle is still running, I will check the diagnostics on the dashboard and it shows no faults: "all systems normal." This is very dangerous as the vehicle can stop running at any moment and could leave me stranded in the middle of the road. I brought the vehicle into the dealership, but they were unable to recreate the problem. While the vehicle was at the dealership, they performed the HVAC control unit upgrade due to a recall. After receiving the vehicle back, this issue has persisted. I do not know if the dealership inspected the vehicle. No other company or entity has inspected the van. This issue first appeared in the first week of November 2025. The issue didn't happen again until 2 weeks later. Now the issue persists almost daily.

NHTSA #11705121

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.

NHTSA #11683819

For the third time the 2025 KIA Carnival Prestige I own lost power while driving on the interstate! Without warning, the vehicle would no longer respond to the accelerator pedal. No matter what I did I could not get the vehicle to accelerate past 35 mph. The minimum speed limit on the interstate is 45 mph. I had to immediately engage my hazard lights and make my way over to the shoulder of the road from the passing lane. This was a dangerous situation for me and my family and others on the highway. Warning lights came on, check engine light, charging system, and a maintenance service message. Driving in Sport mode, Smart mode, nor Econo mode could change the negative situation. This took place multiple times during the final leg of my last trip to [XXX] , extending for over 120 miles. This is a very unsafe, unreliable vehicle, that should never be driven on public roadways… especially not highways nor interstates. Three negatively, traumatic experiences is ENOUGH!!! I’m DONE!!!!

We have been having persistent safety issues with this vehicle. The issues have ranged from unsecured gas cap to loss of power. We’ve also had severe transmission issues where the car will not shift out of first gear. This happened on the Garden State Parkway and nearly caused an accident as the car wasn’t able to go above 27 mph safely.

NHTSA #11740593

When pulling out onto the highway from my drive way the car would no accelerate when I pressed the gas, the car would not exceed 35mph, when caused me and my kids to almost get rear ended when pulling out since the car would not go..... the car will start to flash a " check hybrid system pull over safely" light and then the car will start to coast and I have to find somewhere safe to coast off to, to turn the vehicle off and then on again, it will run fine after that but it will eventually do it again... I have taken the car to 2 different dealerships to have it looked and and they tell me nothing is wrong with it

We purchased this vehicle toward the end of 2024. Within the first 10 months, there were two major recall issues with this vehicle. The recalls were for the 2nd row seating becoming detached from the frame of the vehicle and the other recall was for the computer logic board having the chance of dying and/or frying. These recalls were less than 10 months since date of purchase. There is now another National Recall on this vehicle that was initiated on April 10, 2026. We are a non profit organization and this vehicle is part of our necessary fleet. We called the dealership and was told to bring it in. We brought it in the following week and was told they were not notified yet of a recall. We were told to call back in like 2-3 weeks. We then called back three weeks later and were scheduled to bring the car in for repair. When we arrived at the dealership, we were told "Oh we don't have the parts to fix this. Call back in a few weeks." We waited another three weeks and called back and were scheduled to bring the car in for repair. Now today (June 11, 2026) I went to the dealership and was told once again..."Oh we don't have the parts. Call back in like a month." Now, this recall states that the car should not be driven as the fuel leak is a high chance for a fire. We are desperately trying to have this taken back to the dealership as a lemon car because after we bought this car there have now been three emergent recalls on this car. We paid a lot of money to be able to use this vehicles for our non profit work and over an 18 month period, the car has been out of service for well over 6 months. Dealership seems unable or unwilling to help us. Dealership is: Mark Kia 3333 N 89th St. Scottsdale, AZ 85251

Kia has a recall (Campaign SC 368) on a fuel pipe that may be defective causing a gas leak leading to fire. I called the dealer I bought the vehicle from to request an inspection of the part. I was told Kia will not send letters out until June 2 so dealers are under no obligation to inspect the impacted area before then. Why should a family have to wait six weeks or more on such a critical issue for it even to be visually inspected. Kia's direction is simply to be on the lookout for gas smell and park the vehicle outside. The length of time that they are going to be taking shows a lack of concern for safety, especially since the initial step simply requires inspection of the part. Does the NHTSA have any plans to require car manufacturers to handle all recall matters in a more expedient manner?

Was driving to work this morning and the first time I tried to get accelerate, I was unable to get above 31 MPH no matter how hard I pushed the pedal. Had to stop and restart. Not sure if it is due to the -1 degree weather this morning?

Being a new vehicle the 2nd row seats do not easily slide forward and back. My wife was attempting to move the 2nd row seat forward using the mechanism on the outside of the seat. The back of the seat and the seat moved forward suddenly, striking her in the forehead. The mechanism that holds the 2nd row seat belt is made of a very hard plastic. This hard plastic is what made contact with my wife's forehead, knocked her glasses off and left a swollen lump. The seat belt mechanism and/or plastic material needs to be re-engineered. This could result in a serious injury to a young child or elderly person.

I was on the on-ramp getting on the highway and whenever I started to increase speed and try to get over into the next lane, I noticed the car all of a sudden jumped a little bit and then it started consistently jumping in the check engine light was flashing, and I couldn’t keep the car over what ended up being 50 mph anytime I tried to go over 50 mph. The car jumped in was shaking pretty pretty aggressively I was able to finally make it to a gas station at the very next highway stop and after I shut the car off and turn it back on it seems like it was OK, but I’m still very scared to drive it. I then took it to the dealership to have them check for any store or pending codes because after we had stopped and turned the car back on it no longer had the check engine light on, and the dealership was not able to locate any stored codes in the system to see what it happened nor were they able to replicate the issue that we had found. Is a rec out on my vehicle, but no remedy is available and notices will not be sent for another month and a half at this point I am extremely uncomfortable driving my vehicle as I have young children and anything with a fire hazard is not safe.

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.

NHTSA #11669584

Temperature was 28 degrees outside. Car had 4500 miles on it. Car warmed up for 10 minutes before driving. At the one mile mark, it locked up at 31 mph and 1.4 rpm. It would not accelerate and it maintained the speed and rpm without pressing on the gas. The brakes did work. It lasted for another mile and then resolved. No indicator lights came on. The car did. It recognize there was a problem. It has not been replicated. It is available to be inspected. Not being able to accelerate above 31mph poses significant risk to both my family and other drivers.

NHTSA #11646163

The vehicle shows a Driver Assistance System Warning randomly. Then the vehicle is unable to accelerate past ~30MPH. We almost got hit when this happened. The warning does not show up in notifications nor does it show up in diagnostics. It gets reverts back to normal when the vehicle is turned off then turned back on. It seems to reset.

What component or system failed or malfunctioned, and is it available for inspection upon request? While driving all of the lights in the car went off. Everything internal, and atleast the head lights externally. This lasted for a second or 2 before everything came back on. The screen said something about loss of something, but I don't remember what exactly. This has only happened once. Yes it can be inspected How was your safety or the safety of others put at risk? Atleast the head lights went off while driving at night. Possibly my break lights as well. Has the problem been reproduced or confirmed by a dealer or independent service center? no Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

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.

NHTSA #11627633

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.

NHTSA #11683507

I'm not sure which component caused the issue, but this happened a couple of times already, when I stepped on the accelerator pedal, but the vehicle didn't response at all. The first time, when I was turning into a parking lot, I had to let off the gas pedal, and try it again. The second time this happened was very scary, I was trying to get on to the main road, but I was coming up from a steep hill side road, and I saw a car was coming, but I should have enough/time distance to get on the road, but after the initial acceleration, the car moved forward, but when I applied more power, but it wouldn't move at all! Luckily the oncoming car slowered down and let me go, I was on the opposite lane (incoming traffic), and luckily no car was coming my way. This is 100% safety issue!!!

NHTSA #11640771

My wife and I have a 2025 Carnival SX Prestige Hybrid. We live in northern Maryland (lots of cold days lately!). This exact issue has happened three times and counting. While driving, our car will randomly lose all ability to accelerate. You can press the gas pedal all the way to the floor, and it will not gain speed. It seems to happen at lower speeds, around 30mph and it just caps off and will not accelerate and lose all power. The only thing that fixes the issue is literally pulling over and restarting the car, and then it drives fine. We took it into the dealer after the second incident and they claimed that a camera was just obstructed by ice, so the car probably thought it detected something in front of us so it stopped accelerating as a safety feature. To that, I said “but if the car thought there was something in front of us, it would have applied emergency braking, not just simply stopping any acceleration”… to which they replied “yeah I don’t know. Cars these days are just a giant rolling computer”. The dealer just could not replicate the issue, so they had no way of really seeing or diagnosing it, which I understand but still frustrating. They said they drove it 3 times but it didn’t happen. But again, it happens randomly (though cold weather seems to be a common factor). So we left and said okay, they tried, they cleared off the camera, let’s see what happens. One week later (this morning) happened again. Taking into the dealer this evening. We have a Case open with the Kia Customer Care “Escalations” team. But they’ve been no help.

NHTSA #11637906

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.

NHTSA #11681167

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 contact owns a 2025 Kia Carnival. The contact stated that while driving in warm weather, heat from the exhaust pipe could be felt inside the cabin of the vehicle. As a result, the second row floor would become hot and cause discomfort to occupants seated in the second row. Upon investigation, the contact discovered TSB(Technical Service Bulletin) PI2501, which accurately described the failure the contact had experienced. The vehicle was taken to a dealer where they informed the contact that the TSB remedy was performed on the vehicle prior his ownership. The manufacturer was also notified of the failure and was given the same information as the dealer. The contact was then given a case number and was then referred to the NHTSA Hotline to file a complaint. The vehicle had not been repaired. The failure mileage was approximately 2,5000.

NHTSA #11735144

The Kia Carnival Hybrid wouldn't allow me to accelerate, topping out at 30/31 MPH despite me fully pressing down on the accelerator. It has happened twice now (a few days apart) and can only be resolved by turning the car off and then back on. Compared to similar complaints logged on the NHTSA website, the difference is that this happened when it was roughly 50-60 degrees outside--not during extremely low temperatures as the other examples have described.

NHTSA #11659865

The contact owns a 2025 Kia Carnival Hybrid. The contact stated that while driving at undisclosed speeds, the vehicle hesitated before accelerating while depressing the accelerator pedal. There were no warning lights illuminated. The vehicle was taken to the dealer, who was able to duplicate the failure; however, the vehicle was not diagnosed, and the cause of the failure was not yet determined. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 3,000. The VIN was not available.

NHTSA #11697908

I own a 2025 Kia Carnival SX Prestige Hybrid, and the vehicle intermittently fails to exceed 31 mph when the outside temperature is cold, typically in the single digits or low teens. This issue occurs when I use the remote start system and get into the car to leave for work around 6:50 to 7 am. I have not attempted to replicate this without using the remote start. I have taken the vehicle to the dealership, and they are aware of the problem. They have attempted to recreate the issue but were unable to do so. I have also provided them with a video of the situation and have multiple videos documenting the occurrence.

NHTSA #11645673

When driving the vehicle it would not accelerate beyond 31 mph. We were in traffic so not being able to drive the speed limit posed a risk of other vehicles hitting us. Also when merging into highway speed traffic this was very unsafe. No warning limits or check engine lights came on and the dealer can not replicate the issue nor can they tell us why this happened.

NHTSA #11644663

While driving in the cold the hybrid vehicle will not go over 31 miles an hour. I was turning on to a road that is 45mph and unable to reach a safe speed with traffic. This has happened twice to me now. The dealer can not make it repeat the issue at this time and no warning lights come on.

NHTSA #11643993

The shifter would indicate it's in neutral but the car would think it's in drive. The car was immobilized and could not be moved when hitting the accelerator. This happened in the middle of Baltimore. I had to 'reboot' the car to get it to work, 3-4 times, while sitting in traffic. Problem has surfaced multiple times and is currently at the dealer for this issue. Was recreatable at the dealer. This was after some issue with the hybrid system on the highway where the electrical part of the drive train was inoperable and I had put it in park at a stop light to to try and see if that would fix it. I know the electrical part was inoperable because of how sluggish the car was and the car itself was saying Regen options were not available and the hybrid battery was drained to 0.

NHTSA #11647191

I am submitting a safety complaint regarding the driver monitoring/driver assistance system in the 2025 Kia Carnival. The system repeatedly issues “take a break” or inattentive driver warnings during normal, attentive driving conditions. These alerts are overly sensitive, frequent, and intrusive. Rather than improving safety, the warnings are highly distracting. The visual and audible alerts demand attention at critical moments, pulling focus away from the road. This creates a counterproductive and potentially hazardous situation, especially in traffic or complex driving environments. There appears to be no reasonable way to adjust the sensitivity or disable these alerts without impacting other safety features. A driver assistance system should support the driver—not introduce additional distraction or frustration. I request that this issue be investigated, including the calibration, trigger thresholds, and user control options for the system. A redesign or update may be necessary to ensure the feature enhances safety instead of undermining it.

NHTSA #11734940

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!

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.

Car would not allow me to accelerate. It seemed to keep me running only on the electric motor vs the gas engine (the vehicle is a hybrid). This has happened multiple times. The fix is to turn the car off and on again.

NHTSA #11651616

Car would not accelerate past 30 or 31 MPH no matter how hard gas pedal was engaged. The RPMs increase, acknowledging the gas, but the speed stays the same. Stopping the vehicle and putting in park doesn’t fix it. This is particularly dangerous when going from city street to highway or interstate driving. It eventually self-corrects after about 5 minutes. We’ve experienced multiple instances now, and all have been in cold weather (<10° F).

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?

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.

The component of the vehicle that malfunction was the front passenger seat. The driver came to a stop at an intersection and the front passenger seat started auto reclining. The seat was reclining into a life, flat position, almost. The driver was concerned because no one was pressing buttons and put the vehicle in park in the seat did not stop auto reclining so the driver turned off the vehicle, but the seat reclined as far as it could into the middle section of the vehicle and encountered the driver’s child in a car seat. The seat reclined onto the child's legs and pinned them down against the car seat and the seat below them. The driver was unable to remove the child from under the seat nor able to physically lift the seat, but the buttons on the front passenger seat on the lower right side, did work in order to lift the seat back into an upright position and unpinned the childs legs. The driver took it and to a dealership to get it looked at and they failed to reproduce the issue. The local dealership did look at the vehicle, but failed to reproduce the issue. There were no warning lights to indicate this was going to occur. The local dealership suggested this was a user error, and that something must have damaged the components of the seat to activate an auto recline, which is still problematic. The dealership said due to the owner unplugging the power to the seat that the issue could not occur again, but they did not solve the mystery or issue of how it actually occurred. The child was restrained in a car seat, and the seat was pushed back in the middle section of the vehicle as far back as it can go. The front seat was still able to auto recline somehow into the child’s car seat and pin them down.

4/6/2026 vehicle stalled in traffic multiple times, entered "Limp Mode", unable to accelerate after stopping or after deceleration. I had to press the gas to the floor to get the vehicle to move. While driving, if I had to brake or lay off the gas at all, the vehicle would not accelerate back to the original speed quickly. This put myself and my four children at risk of being rear-ended. I drove with the hazard lights on to Kia of Wesley Chapel Service center. The Battery Management System Warning displayed at the time of the stalling. The Kia Access App displayed the BMS Warning and code P0AA600 (High Voltage Isolation Fault). Initially, Kia of Wesley Chapel Service Advisor stated No warnings displayed and No historical or active codes found. I provided a screenshot of the Kia Access App showing the active BMS Warning and active P0AA600 code at 2:48PM on 4/8/2026. The Service Advisor maintained that they could not find any active or history codes. At 3:00PM the same day, the Kia Access App suddenly showed "No Issues Found". The code was obviously manually cleared. I filed a complaint with Kia Customer Care the same day (4/8/2026) and requested a Kia Technical Specialist be assigned to the case. On 4/12/2026, the original Kia Service Advisor stated "the history code has finally appeared which was the one presented in the screenshot but we cannot replace parts based off of a code that is no longer active unfortunately". He stated they would "keep driving and testing" to try and duplicate the issue. The Kia Access App shows the last trip was 4/7/2026 (the day after I dropped off the vehicle). Interestingly, the vehicle was not moved from the drive up lane at the Service Center until 10:40AM that day, after being dropped off at approximately 6PM the evening prior. I believe they could not get the car to move the evening of 4/6/2026. The vehicle remains at Kia of Wesley Chapel. I am sending the Motor Vehicle Defect Notification to Kia Corporate today.

NHTSA #11732931

The harness straps on the seat have begun to loosen while my child is riding in the seat. You do not need to use the harness adjuster button to loosen the straps. This is allowing a secure fit to become dangerously loose while the vehicle is in motion. I removed the car seat from the vehicle and was able to replicate the issue. A slight tug or movement makes the straps become loose and I can pull them completely out of the shell without using the harness adjuster. This is the same issue that started the Rava recall recently. The harness adjuster is clear of any debris and fully covered by fabric in this seat. There is no valid explanation to this other than a manufacturer defect. The seat is a few years old and has been used daily since receipt in Spring of 2023. It was purchased from the manufacturers website. One minor crash and the seat was not replaced because of the manufacturers stance on replacement (crash was May of 2024). This has been reported to the manufacturer as of 4/29/26.

Date/time of incident 03-16-2026 18:09-18:17 * Faulting component: Infotainment screen (screen to the right of gauge cluster) * Incident: While backing out of a parking spot and utilizing the cameras to watch my surroundings, the infotainment screen became unresponsive and began flashing between visual noise similar to 'snow' on old broadcast television, primary colored jagged/blocky artifacts, and a black screen. The screen would occasionally revert back to normal imagery but with severely lagging touch response and stuttering screen transitions. This persisted until I pulled over, parked the car, & restarted the vehicle. After restarting the vehicle the infotainment screen flashed: Solid Black - Solid White - Solid Red - Solid Green - Briefly solid black - Briefly Solid Green - Then the infotainment functionality returned to normal operation after a brief stutter. --I have a video of the last portion of this incident that I can share upon request * All camera related safety functionality became unresponsive/unusable during this incident * I've requested an appointment with the local Kia dealership * As this incident just occurred, I have not yet reached out to other parties * No warning lamps or diagnostic warning appeared during or after the incident

While driving the car it will stick in the electric mode and not go back into gas mode. You will only be able to go up to 30-35 miles an hour and in order to fix this issue as of right now all I could do was have to pull over to the side of the road put the car in park turn it off and turn it back on. I worry that this issue will be even worse if I was on the interstate and my car was getting stuck in electric mode and then it’s a safety issue, especially since I have kids in the car. I’m majority of the time being a minivan. I have seen other people post on forms about this issue and it not being fixed by Kia

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 car gave alert of "hybrid system failure" and showed a picture of a drained battery. After about 20 seconds, we were unable to drive over 30 mph. After about 30 more seconds, the car shut off and had to be jumped to work again. Luckily we were pulling over into a parking lot when it shut off, but were blocking the entrance. This is the 4th time this has happened in a couple of months since we bought the car.

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.

The vehicle (2025 Kia Carnival Hybrid) has suffered from a systemic parasitic 12V battery drain since the first month of ownership. The first occurrence was July 20, 2025, requiring a jump-start from Kia Roadside Assistance. On 02/26/2026, the vehicle was presented at Moritz Kia Alliance for the same issue. The dealer diagnosed the 12V battery as defective (Code R04) and replaced it under warranty. However, the defect persisted. On 03/10/2026, only 12 days later, the vehicle suffered another total electrical failure. I had to utilize Kia Roadside Assistance for a jump-start and drive the vehicle directly to the dealer without turning the engine off to ensure it could be serviced. This marked the second official repair attempt for this recurring defect. The vehicle has remained in dealer possession since March 10 (21 consecutive days). On March 11, only one day after drop-off, the Service Director threatened that the vehicle would be "impounded" after 60 days, despite the vehicle being the subject of an active Texas DMV Lemon Law Case (#26-0012638.CAF). On March 26, a critical safety failure occurred: during a start-up attempt, the Integrated Power Brake (IPB) system malfunctioned, causing the brake pedal to pulsate and physically "kick back" with significant force against my foot. I have serious concerns that this braking failure could occur while in motion, posing an unreasonable risk of high-speed collision, serious injury, or death. No root-cause diagnosis has been made. Furthermore, the main fuse box cover was left off during service, exposing critical electrical components. The vehicle is available for inspection.

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)

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.

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

Vehicle lost power and would not accelerate past 30 mph even when fully pressing down on the accelerator. After a few minutes a warning flashed to check vehicle hybrid system. Pulling over to the shoulder and restarting the car returned the car to normal operation.

NHTSA #11652939

While coasting at very low speed with foot off accelerator or brake, into a crowded parking spot, the brakes failed after foot applied to the brake petal. This caused our vehicle to collide with a vehicle in front of us, pushing it a few feet backwards. Despite strong effort to push brake pedal down further, car would not stop. Pushed circular park button simultaneously with emergency brake tab which we believe ultimately stopped the car. No usual parking system alerts, beeps, lights, etc., turned on during the collision or near pre-collision. Finally, when car reversed to go home, the car made an unusual jerking movement without the usual reverse 'beeping' noise for the hybrid. Car then behaved normal for the 10 minute tense drive home. We are afraid to drive the car for fear of fatal brake failure to ourselves or others. Vehicle is intact and currently at local Kia dealer for past several days, though purportedly they 'found nothing' and are offering to return the car. Auto claim still pending and once car returned to us, we will have auto insurance rep evaluate the car.

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 a day which had a high temperature of 16F our Kia Carnival Hybrid SXP, after not being used most of the day, when driving would not exceed 31 miles per hour. The engine would not rev loudly or give any indication of an error but would not go over 31 mph even with the gas pedal fully depressed. After pulling over and turning the car off and on the problem did not repeat.

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.
