UNKNOWN OR OTHER
On XXX, the passenger-side power sliding door of my 2024 Kia Carnival EX closed on my [XXX] child’s torso/chest while she was exiting the vehicle and did not stop or reverse before trapping her. I had walked toward the house and reached the garage when I heard an extremely loud scream of pain. I immediately ran back to the vehicle. When I reached her, I personally observed that her torso/stomach was still pinned against the vehicle by the closed power sliding door. She could not move herself away. I had to press the power door button to open the door and release her. She immediately had pain and visible linear red pressure/abrasion marks on her chest/rib area, followed by bruising. She reported increased pain with certain arm/upper-body movements and discomfort in the injured area with a deep breath. Photographs were taken immediately afterward. This occurred during normal use while she was exiting. She was not intentionally obstructing or testing the door. I had previous concerns about these doors and routinely warned my children not to activate them until everyone was clear. Approximately two weeks earlier, a separate accidental obstruction occurred with the OPPOSITE (driver-side) power sliding door. A book accidentally fell into that door’s path without the adult closing the door realizing it. When we later reopened the door, we discovered the book crushed/trapped inside the fully closed door. This was not an intentional test. There were no warning lights or messages. The vehicle has not been repaired or inspected since this injury, and I will not intentionally reproduce the incident because of the risk of injury. The vehicle is available for inspection. I am concerned because two separate obstruction incidents have now occurred involving BOTH power sliding doors, and the latest resulted in my child remaining physically trapped until I manually activated the door to release her.

ELECTRICAL SYSTEM
2026 Kia Carnival Hybrid SX. The digital instrument cluster intermittently flickers, goes blank, and displays “NO SIGNAL” while driving, potentially causing loss of access to speed, gauges, warning indicators, and other safety information. The failures occur unpredictably. I initially noticed the issue after the vehicle had been parked in the sun and the dashboard was very hot, but I do not know whether temperature is related. I first brought the vehicle to an authorized Kia dealer in August 2026. The dealer documented and verified my complaint. The repair order states that moving the monitor caused it to flicker and display “No Signal.” The dealer identified Kia campaign SC361R1 as having an update for this concern and performed the update. The display flickered again while the technician was re-securing it. I was told to return if the problem persisted. It did. The instrument cluster screen goes blank for several minutes at a time while the car is running or it flickers on & off for extended time (up to minutes) and resets to normal randomly. I returned the vehicle for further diagnosis. The dealer again verified the blank/flashing/“NO SIGNAL” condition. Kia Techline directed diagnostic testing and then advised replacement of the instrument cluster. The dealer installed a replacement cluster, but it also went blank and displayed “NO SIGNAL.” Techline then approved replacement of the main dashboard wiring harness. During teardown, the dealer discovered an aftermarket amplifier had previously been spliced into the OEM harness. The dealer now states it is “likely” the amplifier was disrupting the cluster signal and is denying warranty coverage. The exact cause remains UNKNOWN. The vehicle is currently disassembled at the Kia dealer, and the original harness/splice is presently available for inspection. The replacement harness has not yet been installed. Kia America has been notified under Customer Care Case #26389879.

FUEL/PROPULSION SYSTEM
Fuel door actuator is electrically tied to cabin door locks with no manual release and frequently fails to open after repeatedly cycling cabin door locks. Issue is not due to bad batteries or other vehicle related electrical faults. Manufacturer has confirmed defect is present in all Kia models from 2020 until now with no after warranty support.

FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
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.

STRUCTURE:BODY, ELECTRICAL SYSTEM
The power sliding door actuator motor drive cables on my 2022 Kia Carnival snapped on both the passenger and driver sides. The doors are stuck shut, even in manual mode, creating a safety hazard for passengers since the only way to exit in an accident would be through the rear hatch or the front doors. The Kia dealer said they couldn’t open the doors without removing the interior sliding door panels, which would require damaging them because the doors are stuck shut. There were no warning signs before either cable broke. I have also researched online and it seems many Kia Carnival Owners are having the same sort of issue.

UNKNOWN OR OTHER, LANE DEPARTURE: ASSIST
The alert “consider taking a break” with the coffee cup symbol won’t stop going off. It goes off when I first start driving, it goes off every other minute sometimes, it does off for no reason all the time. It is so distracting. Today it was rainy and I’m sure is one reason it kept going off. It was also garbage day and someone put their garbage can on the road right on the line. The alert had gone off 15 times within my 20 minute drive after school drop off. It was making me angry and was super distracting. I was looking at the screen instead of the road as it started beeping again and didn’t see the garbage can. It smacked my side view mirror into the passenger window and shattered it completely. A minor thing, but is going to cost a ton. It’s frustrating to feel trapped into constantly being annoyed whenever I need to drive because there is no way to shut it off, but it literally goes off for no reason. It goes off so much I don’t take it seriously at all. It’s literally useless. And it’s not a little warning. The beeping is loud, the image covers a big portion of the screen, and it turns off my music and my gps prompts. It aggressively demands attention. It can’t keep doing this. I can’t be this distracted with my kids in the car. Every seat is full and I have to drive 30 minutes to one school and 10 minutes to the next school for drop off and pick up every single weekday twice a day. I need them to be safe, but that’s less possible when this alert is constantly going off and demanding attention the way it does. It’s a serious risk. It is reckless to put something so distracting in a vehicle that can cause death from an accident. I could understand if it went off after 4 hours of driving, but that’s not what’s happening. Multiple people have complained about it in social media. Something needs to be done to get this off of or vehicles. It’s unnecessary to suggest someone take a break. Especially after 5 min. That’s not a sensor warning about an actual problem.

Grill on bumper allows large objects to fly through hitting condenser. This is an issue, it happened to my vehicle and the identical loaner car we were given while our car was in the shop for repairs. I was told by the dealership to solve this problem carnival owners should follow other cars at a greater distance. Because I have children I already set my cruise control to follow other vehicles at a 4 car distance…. How much further should a carnival owner allow?

ENGINE
The contact owns a 2024 Kia Carnival. The contact stated that while driving 65 MPH, the vehicle jerked violently and experienced a loss of motive power, with reduced power. Several unknown warning lights illuminated. The vehicle was taken to a dealer; however, the vehicle was not diagnosed or repaired because the warning lights were no longer illuminated. The contact continued to drive the vehicle, and the failure recurred. The vehicle was towed to the dealer and was awaiting diagnostic testing. The manufacturer was notified of the failure. The failure mileage was 48,320.

TIRES:TREAD/BELT
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. Continental was notified of the incident but has not physically inspected the failed tire because it was disposed of by the dealership. Three other factory-installed Continental CrossContact RX tires remain on the vehicle. I am submitting this complaint because of the serious safety concern associated with a reported tread separation occurring at highway speed and because three tires from the original factory-installed set remain in service.

The contact owns a 2025 Kia Carnival. The contact stated that while driving at an undisclosed speed, there was a strong fuel odor inside the vehicle. The contact's minor children were unable to ride in the vehicle due to the odor. Several dealers were contacted and made aware of the failure. The vehicle was taken to the dealer; however, the cause of the failure was not determined. The manufacturer was contacted by the dealer and made aware of the failure. The failure mileage was approximately 6,000.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
My 2024 Kia Carnival smells strongly like gasoline after about 15–20 minutes of driving. The smell gets worse at idle, worse the longer I drive, and seems even stronger with the A/C on. Two dealerships in Las Vegas have told me this is “normal.” Meanwhile, I can’t park it in my garage because the smell fills my house. I’ve had headaches and nausea, and my kids have complained of headaches and stomach aches too.

STRUCTURE:BODY
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.

SERVICE BRAKES, UNKNOWN OR OTHER
On 8/25/2026 I dropped the vehicle at Plaza Kia, 2699 Nostrand Ave, Brooklyn, NY 11210 (Kia Repair Facility #7119189) for four open recalls: PI2501, PI2602, SC320, and SC368. Brakes were functioning normally at drop-off. Per repair order [XXX] dated 8/26/2026, only PI2501 and PI2602 (second-row seat recalls) were performed; SC320 (EGR valve) and SC368 (high-pressure crossover fuel pipe) were not completed — parts on special order. The dealer's multi-point inspection sheet, printed 8/26/2026 12:36 PM, marked brake fluid level/condition and brake system components as OK/green. The technician time log on the RO shows 0.0 actual hours for that day. The brake lining inspection panels on the sheet are blank. The dealer returned the vehicle to my residence via valet on 8/26/2026. On first use, the brake pedal was extremely hard and stiff with the engine running; the vehicle would only slow with full-force pedal pressure. I nearly collided with a parked vehicle exiting the parking space. I parked and did not drive it further. A vacuum-assist test (pump pedal engine off, hold, start engine) showed the pedal sinking only slightly, and braking under drive felt like engine-off braking — partial or total loss of power assist. Kia Roadside Assistance towed the vehicle to Plaza Kia. Plaza Kia refused to tow it themselves. Plaza Kia has since diagnosed a brake master cylinder failure and stated parts are approximately two weeks out. Repair is under warranty; updated RO pending. Kia Consumer Affairs case #[XXX] has been opened. Summary: brake power-assist failure on a 2024 Carnival at ~33,000 miles, occurring in dealer custody or immediately upon return from recall service, on the same day the dealer's inspection cleared the brake system. No prior brake symptoms. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STRUCTURE:BODY, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
I purchased a new 2026 Kia Carnival EX and noticed an unusually intense amount of heat coming from underneath the vehicle on the passenger side, particularly around the rear passenger door/second-row seating area. I first noticed the issue while the vehicle was parked and I was standing outside the open rear passenger door installing car seats and floor mats. The heat radiating from underneath the vehicle was intense enough that my feet and lower legs became extremely hot while standing next to the vehicle I also noticed that the seat/floor rails and other exposed metal components in and around the second-row passenger area became extremely hot to the touch. I could only keep my hand on some of these metal components briefly before the heat became too uncomfortable and I had to remove my hand. I am concerned about the safety of this condition because these hot surfaces are in an area routinely accessed by passengers, including children entering and exiting the second row. I am concerned about the potential for contact burns as well as whether the amount of heat being transferred into the floor, rails, and surrounding components could indicate an exhaust, emissions, heat-shielding, or other mechanical problem. The vehicle is available for inspection upon request. At this time, the exact component or system responsible for the excessive heat has not been identified. The issue has not yet been reproduced or confirmed by a Kia dealer or independent service center. I have contacted Kia service personnel regarding having the vehicle inspected. I was informed that if the vehicle is inspected and the dealership cannot reproduce or identify a problem, I may be responsible for an approximately $210 diagnostic charge. The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or another independent party regarding this issue. There were no warning lights or dashboard messages indicating a problem before or when I noticed the heat
