  NHTSA Vehicle Safety Complaint Vehicle: 2024 Kia Carnival Mileage at Failure: Approximately 74,000 miles Incident Date: [XXX] I am filing this complaint regarding a significant safety-related failure involving the power sliding door on my 2024 Kia Carnival. On [XXX], the driver side passenger power sliding door became completely inoperable due to a latch and actuator failure. Prior to service, the door was stuck in the closed position and could not be opened through normal operation. The vehicle was brought to Kia of Columbia, Connecticut, for evaluation. During diagnosis, the service technician was required to force the door open. Once opened, the door could no longer be closed. The dealership determined that the power sliding door motor actuator had failed and required replacement. When I arrived to pick up the vehicle on [XXX], the sliding door remained stuck in the open position and could not be latched or secured. Because the door could not be closed, the vehicle was not safe to operate on public roads and was effectively undrivable. The replacement actuator was ordered on September 21, 2026. The part did not arrive until September 29, 2026, and repairs could not be completed immediately upon arrival. The actuator was finally replaced and repairs completed on September 30, 2026. As a result, the vehicle remained unusable for approximately twelve days due to the inability to safely secure the sliding door. This failure presents multiple safety concerns: The vehicle could not be legally or safely driven because the sliding door would not close or latch. Occupants were exposed to an open side doorway if the vehicle were operated. In an emergency, passengers could be placed at risk due to door system malfunction. Failure of a critical door component rendered the vehicle unusable without warning. I am particularly concerned because Kia has previously recalled Carnival vehicles for safety defects involving power sliding door INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)

  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.

  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.

  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.

  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)

  On our 2024 KIA Carnival, which my wife is the primary driver, the blind spot warning on the passenger side does not work all the time. Driver side is 100% okay. She drives on I40 and hwy111 to and from work daily, and when passing on the left, she looks for the red triangle to let her know it is clear to get back in the right lane. It only works about 50% of the time and the dealership has worked on it three times unsuccessfully, so we put in a complaint to KIA corporate in June and they have been very unresponsive. We keep the vehicle clean, so it is not that. She just wants it to be reliable for safety reasons and it is not. It probably just takes a different set of engineering eyes to look at it but KIA seems like a dead end so far. Please help us. Thanks. BTW, the people at the dealership have been very good to us, we just believe engineers at a higher level need to solve this problem.

  Recall SC368 was performed. After the recall repair, I began smelling gasoline. The dealer has diagnosed a separate fuel-system issue requiring multiple parts including replacement of the fuel tank. More details: My vehicle underwent a safety recall for a fuel leak/fire risk. Following that repair, I developed a strong gasoline odor. My Kia dealer has now identified a separate fuel-system problem that requires replacement of multiple components, including the fuel tank. The dealer has informed me that multiple Carnivals in Arizona are experiencing the same problem and that a replacement fuel tank is currently unavailable nationwide. I do not have a repair date and I do not consider the vehicle safe to drive.

  This specific van has 2 open recalls already: 1 on a rear seat issue and 1 on a fuel pipe issue which is why i submitted to KIA dealer in the first place after smelling gas inside the cabin of my car while driving for 3 days until the dealer opened. While at the dealer they found a manufacture defect of the gas tank expanding in the heat and releasing liquid fuel into the charcoal cannister meant to catch fumes. The fumes then go into the cabin of the car and smell and make passengers sick as well as create a fire safety hazard on the vehicle. After discovering this they have informed me that the parts for this defect as well as the fuel pipe recall are on national backorder and the solution was to siphon off 1/4 tank of brand new gas and told me not to fill past 3/4 fulls or smoke in the vehicle and they THINK it SHOULD be fine. Google disagrees with this and says once the cannister has had liquid fuel in it, it can cause more problems. They have no loaners to offer as there are too many KIA recalls and they have no ETA on the parts coming in. I have been offered no solutions that are safe besides hold on to the vehicle and maybe it will be ok.

  Incident description: While driving, the vehicle’s dashboard illuminated all warning lights (ABS, traction control, battery, check engine, forward safety system) and the engine revved to approximately 8,000 RPM with unintended rapid acceleration. Driver had to apply hard braking to maintain control and avoid a collision. A nearly identical event occurred approximately one month earlier while driving on the highway, at which point the vehicle suddenly braked hard on its own. The vehicle has been at the dealership for repair a combined 38 days across two visits. The dealer initially attributed the first event to a failed alternator voltage regulator, replaced it, but the same warning codes and behavior returned on the second occasion. Crash/injury: No collision occurred; avoided through evasive braking. Speed: Highway speed (both instances).

  While stopped, the brake pedal drops to the floor and the vehicle begins to roll forward. I went to the dealership and told them what happened, they told me there is no recall on this, and it is a "normal part of driving". This is not a normal part of any braking system. The pedal should not drop to the floor while stopped with your foot on the pedal. No warning system lights that came on. This happens frequently. You have to start pumping the brake repeatedly to get the vehicle to stop. It will eventually raise off the floor.

  Our 2024 Carnival has had a recurring engine oil leak that has required the vehicle to be left at the dealership 4 times for the same issue. Each time we get the van back the repair lasts about 1-3 weeks (depending on how often it's driven). Oil continues to leak from the engine area, creating risk of engine damage or a potential fire hazard if oil contacts hot components. The issue has not been resolved despite repeated repair attempts under warranty. The Carnival has 38,092 miles on it, and has been in the repair shop over 4 times. The 1st time it was put in the shop the van has 34,420 miles on it. Each time it has been left at the dealership for 9 - 17 days while the repairs were made. We have brought it to the same dealership each time and they have been very sympathetic and helpful. Not only does this issue cause the risks mentioned above, but it has ruined the concrete in my garage as well as added oil to the roadway which could cause an accident. I have all the repair orders from the first 3 repairs that I will attach. However I do not have thee current one because the vehicle is currently being repaired for the 4th time and I haven't received the finalized repair order documents. I can update this claim once the repairs are completed. I will be contacting Kia tomorrow and wanted to have a claim number started.

  I purchased this 2024 Kia Carnival on 2/7/2026 with less than 10K miles. The vehicle has died while I was driving 4 different times. Twice each day that it happened. The first time was on 4/7/26. My car died on the way home from getting my kids from school after fixing a flat tire. The check engine light came on after getting a jump and when I took it to Auto Zone the battery was fully charged and the codes were for the Power Train, which didn't make sense for a brand new car. Miracle Mart told me that Kia needed to be utilized for any issues because I purchased the vehicle as is. Their solution was to tighten the "loose cables". On 4/25/26 the car died again two more times. Something is terribly wrong with this car.

  The fuel pipe in my 2024 Kia Carnival has been identified by Kia as part of Safety Recall SC368 due to a fire risk. The component is available for inspection at the dealership where the vehicle is currently located. My safety and the safety of my family — including young children in car seats — was put at risk because the vehicle carries a known fire hazard related to the fuel pipe, yet no remedy is available until June 2026 at the earliest, according to Kia Customer Care. Kia confirmed the recall and the fire risk but has not provided adequate alternative transportation, leaving a family with young children without a safe vehicle for an extended period. The problem has been confirmed by Kia Customer Care, who verified that my vehicle is included in recall SC368. The dealership also confirmed the recall exists but stated the remedy is not yet available. However, when I contacted NHTSA by phone to file a complaint, the representative stated they could not find my vehicle in their recall database, directly contradicting Kia's confirmation. This discrepancy between Kia's internal records and NHTSA's database is concerning and may prevent other affected owners from being aware of the safety risk. The vehicle has been surrendered to the dealership via tow due to the fire risk. It has not yet been inspected or diagnosed by the dealership service department. I have requested written confirmation that the vehicle is safe to drive before accepting it back. I was notified via a CARFAX alert and the risk was identified/confirmed by the manufacturer.

  I reported a fuel smell in the cabin of my vehicle in June 2024. It was dismissed because they could not recreate the smell. I reported it again and they said that is just how the vehicle purges fuel. I reported it again and drove it right to the dealer when it smelled and multiple mechanics at KIA confirmed they smelled it. Reported it again in September 2024, then tried to deal with it, and reported it again in June and July 2025. In July they confirmed I had raw fuel in my evaporator canister. I also had misfire notifications on my dashboard which were dismissed as they could not determine where the misfire was coming from. The misfire stopped after they replaced my fuel canister but the smell never fully went away. I received an email follow up in July 2025 and I reported the smell was not as strong, but still occurring intermittently. They closed the case. I reported and had 2 open cases with KIA, and noted that I was feeling lightheaded and nauseous, as well as 2 of my 3 kids at the time.

  My Kia vehicle has an ongoing engine oil leak that has not been properly repaired under warranty. The vehicle was taken to an authorized Kia dealership for diagnosis and repair of the oil leak. I was informed by the dealership that Kia engineers indicated that in similar situations the typical resolution is engine replacement. However, in my case, the dealership was instructed to attempt sealing the oil pan instead of replacing the engine. I was advised that if this repair did not resolve the issue, I could bring the vehicle back for further service. Unfortunately, the oil warning light has now returned on the dashboard, indicating the issue persists and the repair attempt was not successful. An unresolved engine oil leak presents a serious safety concern because loss of engine oil can lead to engine damage, stalling, or failure while driving. This creates a risk of unsafe driving conditions, especially when transporting passengers. My family relies on this vehicle for daily transportation, and the continued presence of the warning light makes the vehicle unreliable and concerning from a safety standpoint. In addition, the dealership has not provided a suitable loaner or rental vehicle large enough to accommodate my family while the vehicle is undergoing repair. This has created significant hardship as we do not currently have reliable transportation. The manufacturer should correct this defect properly and ensure the vehicle is safe to operate rather than attempt temporary or experimental repairs that do not resolve the root cause. The persistence of the oil leak after warranty repair raises concerns about the reliability and safety of the engine. I am submitting this complaint to document a potential engine defect that may pose a safety risk if engine oil loss leads to engine failure while the vehicle is in operation.

  Horns (high and low) have been replaced 5 times under a warranty. This is a serious safety hazard. Vehicle: Kia Carnival (Model Years 2022–2024) Issue: Repeated horn failure / electrical malfunction Owners of 2022–2024 Kia Carnival vehicles are experiencing repeated horn failures that present a safety concern. Reported symptoms include complete loss of horn function, intermittent operation, delayed response, and in some cases random horn or alarm activation without driver input. When the failure occurs, both the high-pitch and low-pitch horns are often found to be inoperative. Many owners report that dealerships replace both horns, sometimes multiple times, with some vehicles requiring second or third replacements. Kia has acknowledged this issue through a Technical Service Bulletin (ELE-263), which instructs dealers to replace both horns when one fails; however, the bulletin does not identify a permanent root cause or corrective design change. As a result, the issue frequently recurs after replacement. A non-functional or intermittent horn significantly reduces the driver’s ability to warn other road users and avoid collisions, creating a clear safety risk. Given the recurring nature of the failure across multiple model years, this appears to be a systemic defect rather than isolated component wear.
