"UPDATE TO EXISTING COMPLAINT NHTSA ID 11747231 LCD CENTER DISPLAY / BACKUP CAMERA FAILURE UPDATE TO NHTSA COMPLAINT ID 11747231 I am submitting an update regarding the same unresolved safety defect reported in NHTSA Complaint ID 11747231 involving my 2025 Kia Carnival SX. Mileage when the problem start approximately 8k miles. The vehicle has now undergone five repair attempts for the same recurring LCD/display failure. Repairs have included replacement of the LCD/display, replacement of the radio/head unit, work involving coaxial connections, and most recently repair of what the dealership diagnosed as “insufficient pin tension.” Kia Tech Line has also been involved. Most recently, I was told the vehicle was repaired and ready for pickup. However, when I arrived at the authorized Kia dealership, the LCD began flickering again while the vehicle was still in the dealership parking lot. Dealership personnel witnessed the failure and recorded video of it. The defect remains unresolved. The display has previously gone blank while driving, caused navigation to become unavailable, and caused the rearview/backup-camera image to become unavailable while reversing. This recurring failure is causing me significant stress and distraction while driving because I do not know when the screen will suddenly begin flickering or go blank again. When the screen unexpectedly flickers or fails while I am driving, it draws my attention away from the road. The loss of the rearview-camera image whil

On August 31, 2026, while traveling eastbound on I-14/US-190 in Killeen, Texas toward Temple, an original factory-installed Continental CrossContact RX 235/55 R19 101H tire on a 2025 Kia Carnival Hybrid suffered a major failure at approximately 28,975 vehicle miles. A toddler was a passenger in the vehicle. Prior to the failure, there was an unusual tire noise, followed by a much louder noise and the smell of burning rubber as the tire came apart. There were no known tire-pressure warnings or other warning messages before the failure. Fortunately, the driver was able to maintain control of the vehicle and safely pull off the highway. There was no crash, fire, or injury. Kia Roadside Assistance towed the vehicle to a Kia dealership. The failed tire was replaced. A service advisor at the dealership who personally observed the failed tire subsequently stated that what he observed was tread separation and not road-hazard damage. Approximately 7,091 miles before the failure, at 21,884 vehicle miles, a Kia multipoint inspection documented all four factory-installed Continental tires at 7/32-inch tread depth with “NO DAMAGE.” The tires had also received documented rotations during the vehicle's service history. The failed tire is no longer available for inspection. I contacted the servicing dealership the morning after the incident specifically regarding retaining the failed tire. When I later returned to the dealership to follow up, I learned that the tire had been disposed of. Con

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

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.

**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.

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 v

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!!!!

Chest Clip, Buckle, Harness
Filed Apr 30, 2026FL

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.

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.

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.

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. F

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.

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.

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

I WAS DRIVING TO WORK AND HEARD A LOUD NOISE, THEN THE SOUND OF GLASS SHATTERING. I PULLED OVER AND LOOKED AT ALL MY WINDOWS AND DIDNT SEE ANYTHING. I CONTINUTED DRIVING AND I COULD HEAR AIR COMING FROM ABOVE, WHILE AT A REDLIGHT I STARTED OPENING THE SUNROOF COVER AND SAW GLASS. I IMMEDIATELY CLOSED IT AND RETURNED HOME AND GOT MY OTHER VEHICLE. THERE WAS NO CARS IN FRONT OF ME AND NOTHING ABOVE ME.

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.

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.

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

The 2025 Kia Carnivals have a safety systems that prompts the driver to, "Take and coffee break". The system cannot be turned off and is extremely distracting. The system prompts the driver even if the adaptive cruise control is turned off. I called Kia and they told me to take the vehicle to the dealer. The dealer was not able to turn the computer nag off either. The car makes a noise and the prompt flashes at the driver every few miles. This happens when traveling at highway speeds and in traffic. The driver has to look down from the road to see what the noise is and is greeted with the infuriating "Take a coffee break" message. It is extremely distracting and annoying to the point it induces road rage. The NTSB needs to investigate this system and require manufacturers to either allow owners to turn it off or do not include this feature in their vehicles. The next question is irrelevant because this happens on almost every highway drive. It is not a one time occurrence.

Vehicle Malfunction Report What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle's transmission and/or gear shifter system has failed to function as intended. When the gear shifter is set to "Reverse," the transmission has repeatedly shifted into "Drive" or "Neutral" instead. Concurrently, the vehicle's electronic backup camera system and audible sensor beep activate, indicating that the vehicle believes it is in reverse. The van is available for inspection upon request. How was your safety or the safety of others put at risk? My safety and the safety of others were put at risk on multiple occasions due to the vehicle shifting into the wrong gear. This has caused the van to unexpectedly lurch forward when I intended to back up. I have nearly collided with other parked vehicles and my garage door between 10 to 20 times. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem has not yet been reproduced or confirmed by a dealer or service center, but it has occurred on numerous occasions and is a confirmed issue by the driver. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? To date, the vehicle and its components have not been inspected by the manufacturer, police, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

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

On two separate occasions, [XXX] and [XXX], I received emails from Kia Connect giving me a 12-Volt Battery Discharge Warning. I have the car out at the local dealership right now and they say there is nothing wrong with the battery but they are replacing it. I have noticed online multiple owners are complaining of the same issue and Kia has had a recall of a similar issue with a different model of car in the past.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
