ENGINE
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.

STRUCTURE
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.

LANE DEPARTURE: WARNING
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.

Chest Clip, Buckle, Harness
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.

ENGINE
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.

ENGINE, FUEL/PROPULSION SYSTEM
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.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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?

SEATS, ELECTRICAL SYSTEM
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.

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.

ELECTRICAL SYSTEM
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.

POWER TRAIN, ELECTRICAL SYSTEM, SERVICE BRAKES
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.

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, ELECTRICAL SYSTEM
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

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.

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.
