2025 Kia Carnival

The vehicle's passenger cabin continually has a strong odor smell after longer drives or after the vehicle idles for a longer duration in time. The vehicle was brought to Horne, KIA in Gilbert, AZ twice in June for same. Both times the service department stated they could not duplicate the problem and could not ascertain that it has anything to do with recall SC368. The problem continues at time of this writing (07/14/2026). The strong fuel odor is causing headaches to family and young children. The problem could not be reproduced but matches the SC368 recall. KIA Customer Service was contacted today, and they advised the only thing they can do is trust their authorized service department that there are no concerns (Horne KIA). I requested the matter be escalated, but my request was denied.

On five separate occasions, while turning onto a high-speed roadway and attempting to accelerate to the flow of traffic, the vehicle suddenly lost the ability to accelerate. Despite pressing the accelerator, the vehicle would not exceed approximately 35 mph and then began to decelerate. During both incidents, a "Check Hybrid System" warning appeared, and I was forced to quickly pull over to the side of the high-speed road. The vehicle would only return to normal operation after it was turned off and restarted. This loss of power while merging into traffic created an extremely dangerous situation. Having three young children in the vehicle made the experience especially frightening, and I no longer have confidence that the vehicle can be relied upon to operate safely. Because this defect affects the vehicle's ability to accelerate safely in traffic, I am deeply concerned that it could result in a serious collision if it happens again. I took it into the dealership and the service center experienced the same issue. They thought they had resolved the issue and that it was a "one off" occurrence but it happened to me again just 3 weeks after the attempted repair. This time the engine light came on after the "Check Hybrid System" warning light.

The contact owns a 2025 Kia Carnival. The contact stated that while parked in a bank drive-thru, the contact's son mentioned that his seat belt was stuck. The contact parked the vehicle in a parking spot and attempted to remove the seat belt; however, the seat belt retracted tightly around his abdomen as the lower half of his body was turning blue, requiring the contact's husband to cut the seat belt. The contact mentioned that it was discovered that all seat belts located in the rear row seats failed. The contact stated that several unknown warning lights were flickering on and off back in April. The vehicle was taken to a dealer, where it was diagnosed that all the third-row rear seat belts had failed and needed to be replaced. The vehicle was repaired by replacing the seat belts. The manufacturer was notified of the failure and informed the contact that the seat belts were replaced and that the vehicle was ready to be picked up. The approximate failure mileage was 46,000.

I live in [XXX]. On the way to [XXX], out of no where the car stopped accelerating. Was in eco mode at the time and dropped completely while trying to accelerate in the middle of the road. Pulled over completely turned off the car checked the engine nothing seemed out of the ordinary. Ran the diagnostics from the car and didn’t show any errors. Turned off again for a bit and turn on and everything was fine. Moved from eco to smart and turned around worked fine for about 5 m so we thought everything was on and tried to go back north to finish our trip and while on smart mode started to accelerate again and didn’t want to accelerate. Turned around and decided best to take it to dealership Monday. We have about another 1 hour to 2 hours to get home and it’s working fine in smart mode but it shouldn’t randomly drop acceleration at all in the middle of driving. Only at 16,487 miles. Doing it again only driving 33 m an hour and in smart mode. Not even going uphill just dropped acceleration while driving around town. About 15 m after. There’s still no error happening when it happens each time. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

**Vehicle:** 2025 Kia Carnival **Current Mileage:** Approximately 18,000 miles I am reporting a serious and ongoing safety defect involving the center LCD display in my 2025 Kia Carnival. The problem began immediately after the vehicle's first scheduled service at an authorized Kia dealership and has continued ever since. The center LCD screen intermittently flickers and then goes completely blank while I am driving. When this happens, the rearview camera image is also lost while the vehicle is in Reverse, leaving the display completely black and preventing me from seeing behind the vehicle during backing. This creates a significant safety hazard and increases the risk of striking a pedestrian, child, vehicle, or other object. The display failure while driving is also extremely distracting because critical vehicle information and functions become unavailable. I have taken the vehicle to authorized Kia dealerships multiple times for warranty repairs, but the defect remains unresolved. The LCD display has been replaced, yet the problem continues to occur. The dealerships have kept my vehicle for extended periods during several repair attempts without permanently correcting the issue. Service dates include: * September 9, 2025 * March 10, 2026 * March 18, 2026 * June 1, 2026 The issue is intermittent but repeatedly occurs without warning. I transport my family, including infants, in this vehicle, and I am extremely concerned about their safety and the safety of others. Losing the backup camera and display while reversing or driving creates an unacceptable safety risk. I believe this may be a safety-related defect affecting the vehicle's display system. I respectfully request that NHTSA investigate this issue because multiple warranty repair attempts, including replacement of the display, have failed to resolve the defect.

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

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)

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!!!!

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.

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.

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.

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.

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.

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?

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.

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.

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.

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.

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

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.

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?

TL;DR : Vehicle engages limp home mode without any notification to the driver that it is in limp home mode and doesn’t generate any codes for technicians to identify why the vehicle went into limp home mode. During oil changes, a significant amount of residual oil remains in the engine. When the lube tech fills the oil using the recommended amount, engine is actually over full of oil as indicated on the dip stick. The vehile will start and run fine for a while. Later however, an oil pressure sensor will detect the over full status and put the car into limp home mode. No check engine light, no oil light, no indicator saying it’s in limp home mode, and when the service tech investigates, no code thrown for the issue. A manual checking of the dip stick will reveal the oil is over full. The fix is to drain oil to normal levels as shown on the dipstick. It isn’t a defect considering that it’s reasonable to expect a vehicle to be operated with the correct amount of oil. A future software update for the oil sensor to throw a code for the tech would be appropriate.

My 2025 Kia Carnival Hybrid produces externally audible audio while the vehicle is locked, with all doors and windows fully closed. Private phone calls, navigation instructions, and other in-vehicle audio can be clearly heard from outside the vehicle indefinitely, even after locking the car. This behavior occurs without warning to the driver and cannot be disabled or controlled through any user setting. The dealership and manufacturer have confirmed this behavior is “by design” and have declined to correct it. This presents a safety and security concern, as it exposes private communications, signals whether a vehicle is occupied, and may attract unwanted attention or increase the risk of harassment, stalking, or theft—especially in parking garages, residential areas, or public locations. The vehicle appears secure to the driver (locked, windows closed), yet continues to broadcast audio externally, which is unexpected and undocumented behavior. I believe this constitutes an unintended external output of vehicle systems while secured, creating a potential safety vulnerability.

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? Just the message on the screen

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.

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.

The component that has failed are both Rear Entertainment System (RES). The vehicle is at the dealership and they are unable to determine the cause hence the vehicle is at the dealership for an additional day. There were no warning lamps, messages or other systems of the problem prior to the failure. The failure happened Oct. 5, 2025. I also called KIA Connect Center on Oct. 9, 2025 and they recommended a soft reset which did not resolve the issue hence finally able to take it to the dealership on Nov. 24, 2025.

The 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.

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.
