My 2025 Kia Carnival Hybrid was purchased new in January 2025. The problem began almost immediately, with the vehicle first presented to an authorized Kia dealer for this condition at only 810 miles. The vehicle repeatedly and unpredictably enters reduced-power or “limp mode,” causing a sudden loss of normal acceleration and limiting it to approximately 35 mph. This creates a serious safety risk on highways, while merging, crossing intersections, or whenever acceleration is needed to respond to traffic. Equally concerning, the vehicle does not consistently display a warning or retain a hard diagnostic error code when the loss of power occurs. Sometimes a check-engine light or “Check Hybrid System - Stop Safely” message appears, but at other times the vehicle enters limp mode with no warning. After turning the vehicle off and restarting it, normal operation may return and the error disappears, leaving the dealer unable to retrieve a stored code showing what occurred. The vehicle has been presented to an authorized Kia dealer for this recurring issue at least five times. In August 2026, it remained in limp mode and had to be towed to the dealer. We were initially told no error code had been found. Near the end of the service period, we were told a code had appeared indicating a faulty sensor, which was replaced, but the reduced-power problem later recurred. The vehicle’s automatically generated August performance report also indicated no vehicle issues despite the August incident. A Kia TechLine case was later opened, but the recurring problem was not identified or permanently corrected. The vehicle is available for inspection.

On XXX, at about 4:50 PM, my [XXX] son’s hand was caught in the left (driver-side) power sliding door of our 2025 Kia Carnival Hybrid (VIN [XXX]; approximately 30,000 miles). The power sliding door was enabled and the door-close function was activated using the interior button. The door did not stop or automatically reverse. It closed completely and stayed latched on his finger. I had to open the door manually to release his hand. An X-ray confirmed a broken finger. I am concerned that the powered sliding door’s obstruction detection and reversal features did not prevent this crushing injury. I request that NHTSA review this incident as a potential child-injury motor vehicle safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In May 2026, after driving through a heavy rainstorm on the highway, the car suddenly cut off cruise control and showed multiple warning lights (for most, if not all assistance systems) and an error message that was some version of "check hybrid system." When searching the code it seemed to be related to an electrical short in the hybrid system. I had no electric power to the engine, but the gas functionality still sort of worked, so I could drive, but there was a 2-3 second delay between pushing the gas pedal and getting any acceleration, and said acceleration was minimal. This occurred at 70+ mph on a busy highway, so the sudden lack of acceleration and control was alarming and put us and the cars around us at risk due to sudden speed change. When we pulled into a safe stop and turned the car off for a few minutes and then back on, the error messages were gone and hybrid system seemed functional again. The check engine light remained, but turned off after the next short trip. There had been no warnings, lights, or symptoms of any issues at any point prior to this occurring. The car was not seen at the time due to being on vacation and not near any Kia dealership. It is being seen in a few weeks, but as this was 5 months ago, I do not anticipate anything being found to explain the issue, particularly after reading other online reports of this issue. A similar issue happened recently (Oct 2026) with no rain present. I had just started driving, and got a warning about lane-keeping assist, but no others. I pulled over, couldn't find any other errors or details, and everything else seemed fine. I continued driving, and 1-2 minutes later, while trying to accelerate onto the highway, I suddenly had no acceleration power with the pedal touching the floor. I was again at risk of a high-speed accident if I had not been able to move the car toward the shoulder quickly. No error code appeared at the time of acceleration loss. Power returned after restarting the car.

The contact owns a 2025 Kia Carnival. The contact stated that her child screamed when the rear passenger’s side sliding door failed to detect the child's hand and closed on the child’s hand on four separate occasions. The contact pressed the rear sliding door button to release the door from the child's hand. The failure resulted in a door indentation across the child's four fingers, but no medical attention was received. Prior to the failure, the vehicle was taken to the dealer for the front driver's side door that failed to latch unless the door was slammed closed. The dealer previously inspected the doors, but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure by email. The failure mileage was 18,529.

Within 5 minutes of driving, the car stopped accelerating. Check hybrid system alert appeared one minute later. Car stalled out within approximately 1-2 minutes after warning light appeared. No other warning lights were present prior. This is a 2025 new Kia Carnival Hybrid. I was stranded on the side of a 55mph road. The first time the police helped me roll it off the road. The second time it couldn’t be pushed even though it appeared to be in neutral. The car dies but the accessory functions will not turn off. We have to unplug the battery each time. This car could die ANYWHERE leaving you stranded in a very dangerous situation. There is very little warning. This is extremely hazardous. This is the SECOND time this has occurred with a combined total of 5 hours waiting for tow trucks and countless hours contacting Kia. Kia kept the car for two weeks and recharged the battery. That’s it. It died again within 24 hours of being returned to us. This is UNSAFE and unreliable.

This complaint is a follow up to complaint #XXX. I took the car in to Dennis Eakin Kia in [XXX] to repair what caused the car to go into Limp Mode after slamming on the brakes. The dealership did a deep scan of the hybrid control and power train control module for historical or iintermittent codes. They could find none because the car apparently does not save them after the ignition is turned off. They are trashed. They also tried 4 times to re-create the event by slamming on the brakes, but were unable to re create it. They returned the car to me without fixing it. This is another deep -imbedded safety hazard of this car that a well-documented safety hazard from many drivers cannot be fixed because the car trashes any evidence of these incidences. This car is a clear danger to drivers, a danger that can only be fixed through a recall to get them off the road until a fix is executed by the manufacturer.

I had to slam on my brakes and the car went into Limp Mode, not allowing acceleration above 20 MPh. I drove for a while and then pulled into a parking lot and turned off the car and back on again. I was able to achieve normal acceleration after turning the car back on. We felt unsafe having no control over our speed and cars honking and racing around us. I am afraid to drive my family in this car for fear of having to slam on my brakes at a highway intersection or off/on ramp, which could cause a fatal crash. A Kia dealership is performing a diagnostic now and will advise. The vehicle has not been inspected by another agency. No warning lights went on that I can recall.

On random occasions, car will display "check hybrid system" and go into limp mode (limiting speed significantly) check engine, oil, and battery lights also illuminate. Had car serviced twice by dealership who cannot replicate the error, nor can they find any engine codes stored. However, this incident keeps occurring. Planning on having the car serviced again and not picking it up until it's figured out, but also wanted to report this incidence as I have seen several posts with other people complaining of the same issue. Concern is for if this happens randomly at freeway speeds and becomes a serious road hazard.

The passenger-side sliding door closed while I was holding my son and leaning into the passenger doorway. At the time the door was closing, my son’s left foot was still inside the doorway. The sliding door closed directly onto his left foot and remained fully closed on his foot rather than stopping or reversing. His foot was trapped by the closed door until we were able to open it. This incident resulted in significant bruising to his left foot and concern for a possible fracture. The failure of the sliding door to detect the obstruction and stop or reverse put my son’s safety at serious risk and resulted in injury. The component involved was the passenger-side power sliding door and/or its obstruction detection/anti-pinch safety system. The vehicle and door are available for inspection upon request. At this time, the problem has not been reproduced or confirmed by a dealer or independent service center. The vehicle/component has not yet been inspected by the manufacturer, police, insurance representatives, or others in connection with this incident. There were no warning lamps, warning messages, or other symptoms that we noticed prior to the incident indicating that the sliding door or its safety system was malfunctioning.

The digital instrument panel display on the right side that shows map direction goes blank or start flickering. Audio also fails to function. When it goes blank, the rear camera also stops showing and causes difficulting in reversing the car. This happens randomly, but mostly once car has driven 10-15 mins or more and not right away. Points to some effect due to heat or vibration since the screen flickering begins once its driven a little bit.

I am writing to formally report a serious, recurring safety defect involving the Heating, Ventilation, and Air Conditioning (HVAC) system in my vehicle. The system intermittently shuts off completely without warning and suffers from a malfunctioning airflow diverter. This directly impacts driver visibility due to immediate windshield fogging or the inability to de-ice during cold weather conditions. Below are the logged details of the intermittent shutdowns: July 9: System shut off 22 minutes into the drive. Local time: 07:58. Ambient temperature: 76°F. Vehicle settings: 72°F, Fan Speed 3.July 11: System shut off 34 minutes into the drive. Local time: 17:10. Ambient temperature: 92°F. Vehicle settings: Low, Full Blast. Furthermore, the airflow diverter is partially stuck on defrost mode. Air constantly blows onto the front windshield regardless of the chosen setting on the selector. This uncommanded airflow creates rapid temperature differentials on the glass, causing severe condensation and clouding the driver's line of sight during operation. These compounding HVAC failures constitute a significant safety hazard by unexpectedly distracting the driver and severely reducing visibility. I request that these issues be documented and investigated for potential safety recalls. Currently, my vehicle is in the shop with a local KIA dealership. A KIA corporate service technician is on ground and investigating the electrical and HVAC issues. Feel free to reach out for additional observational notes that I have compiled.

This is a bran new vehicle purchased and only driven by me. I have video evidence that on the morning of 8/10/26 my windshield was perfectly fine. On returning at the end of the work day there is a 2 foot long crack internal to the windshield, a stress crack, that starts where the sensor panel is. There are numerous reports of this happening to a large number of Kia Carnival owners and Kia refusing to warranty this.

My 2025 Kia Carnival Hybrid is experiencing repeated electrical and hybrid battery failures. The battery has died multiple times, and the vehicle has shut off while driving, including at higher speeds. When the vehicle shuts off, all electrical systems reset, warning lights flash, and the dashboard displays “User Authorization” notifications. This creates a serious safety hazard for me and my passengers. The defect has occurred multiple times and remains unresolved despite dealer visits. Kia corporate is not responding and is redirecting me back to BBB Auto Line without providing any repair plan. The defect is ongoing and poses a risk of crash, injury, or loss of vehicle control. These symptoms match other Carnival electrical/battery complaints already filed with NHTSA, including sudden shutdowns, battery failures, and electrical resets. I am submitting this report because the defect continues and Kia has not provided a permanent repair.

While my 2025 Kia Carnival Hybrid was parked, my [XXX] child attempted to unbuckle the rear passenger seat belt to exit the vehicle. The buckle mechanism jammed completely and would not release. The seat belt retractor then switched into Automatic Locking Retractor (ALR) mode, continuously tightening and squeezing my child against the seat. Due to the jammed buckle and the aggressive ratcheting of the belt, my child was nearly choked, and I could not create enough slack to free them. I was forced to call 911, and responding emergency services had to physically cut the seat belt to extract my child safely from the vehicle."

I had two very serious incidents. July 8th: Horn just started blaring unprompted. Locking/unlocking doors, turning motor on, disconnecting battery did nothing to stop it. I was trying everything and as I was trying to find the correct fuse to disable (it wasn't labeled), the horn burned out and started smoldering. If the car was not in my driveway AND I wasn't home, I believe a fire would have started if I didn't pull the fuse AND douse it with water. It was parked next to my garage, so that would have been at risk as well. July 11th: When driving, my brake line burst resulting in a complete failure of my brakes. I narrowly escaped two accidents before I realized something was amiss. But the only warning was ABS was inactive, and active cruise control wasn't working. I had no warning that complete brake failure was imminent. I was extremely lucky. Mechanics had never seen a brake failure fail in a relatively new car in very good condition.

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.

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)

The vehicle began shaking and having ABS problems when driving at ~30 mph after having driven for several miles without issue. The vehicle did not have any history of problems or recent symptoms and was just over one year old. The vehicle was towed to the dealership. The dealership reported a broken driver side front wheel speed sensor wire and attributed it to rodent damage without other evidence.

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.

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)

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.
