The 2024KIACARNIVAL carries 75 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 3 crashes, 0 fires, 12 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 4/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2024 CARNIVAL is unknown or other with 18 filings, followed by electrical system (14) and steering (7). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 1 investigation file overlapping the 2024 CARNIVAL. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Kia America, Inc. (Kia) is recalling certain 2023-2024 Sportage and 2022-2024 Carnival vehicles. The roof molding may loosen and detach.
Horn stops working and needs to be replaced within a year or less. I reported the first time my horn stopped working and it took 4 months until I can have an appointment and order the part. The second time it stopped working was within a year and scheduling an appointment was difficult. I was almost in an accident and unable to use to both to alert the other driver.

Horns (high and low) have been replaced 5 times under a warranty. This is a serious safety hazard. Vehicle: Kia Carnival (Model Years 2022â2024) Issue: Repeated horn failure / electrical malfunction Owners of 2022â2024 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

On 11/12, my 2024 Kia Carnival was parked as my children were getting settled in the vehicle. My son lifted the second-row passenger seat on the passenger side using the handle provided to access the third row. As he did so, the seatback suddenly collapsed forward with unexpected speed and force and locked in the forward position. Nothing broke, and the mechanism did not appear to jam. The seat moved along its normal path, but it did so so aggressively that it crushed my [XXX] daughterâs left leg while she was strapped into her car seat directly next to it. She was asleep, the car was not moving, and the seat feature was being used in a normal way to access the third row. The force of the collapsing seat fractured her left tibia, confirmed by X-ray. She is currently in a medical boot and under a doctorâs care. This vehicle has no accident history and no modifications. We have multiple witnesses (myself and our children), photos of the injury, and a video that shows how fast and
The contact owns a 2024 Kia Carnival. The contact stated that while driving at various speeds, an abnormal gas odor would emit through the vehicle's ventilation system. The contact notified a local dealer, and an appointment was made to have the vehicle serviced. The vehicle was inspected, and the contact was informed that there was likely bacteria growing inside the vehicle, which caused the odor. The contact disputed this claim and recommended that the air filters be replaced; the contact paid for the repair. Despite the repair, the contact stated that the fuel odor had become a chemical odor, and the vehicle was taken back to the dealer. The dealer confirmed that they had smelled a fuel odor inside the vehicle and informed the contact that she had overfilled her fuel tank with gas. While the contact also disputed this claim, the dealer later concluded that the dipstick inside the oil pan was not properly sealed, and the dealer repaired the defect. Despite the dealer's claims and rep

Both horns went bad on my vehicle that is less than 2 years old. Dealership said ours is the 5th vehicle they have seen this week with the same issue. They have been unable to determine a cause.

I am submitting this complaint regarding my Kia Carnival. The vehicle has a recurring and dangerous problem where the engine suddenly jumps and, if I continue pressing the gas, it shuts off while driving. This has happened multiple times, including in the middle of the highway, creating a serious safety risk for myself, my passengers, and other drivers. I have taken the vehicle to a Kia dealership on multiple occasions, but they have not been able to identify or repair the issue. I also contacted Kia corporate, obtained a case number, and was told someone would follow up with me. Unfortunately, no one has ever called me back. This is an ongoing and unresolved defect that puts my family and the public in danger. I request that the NHTSA investigate this matter to determine if this is part of a larger safety defect in Kia Carnival vehicles.

The contact owns a 2024 Kia Carnival. The contact received notification of NHTSA Campaign Number: 24V025000 (Structure). The contact stated that the driver's side roof molding was detaching, and the contact attempted to secure the molding in place several times. The dealer was contacted to schedule an appointment for the recall repair, but the dealer informed the contact that the recall repair had already been performed while the vehicle was at the dealer for an unrelated service, a month prior. The contact stated that the dealer had failed to perform the recall repair correctly because the failure persisted. The manufacturer was notified of the failure, and a case was filed; however, no assistance was provided. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 25,000.
Mileage: 25,000
A/C system on my 2024 Kia Carnival failed twice within weeks. First at 60,100 miles, repaired at dealership for $398. Then again shortly after, leaving vehicle undrivable in summer heat. Kia has done nothing despite having a case number (#25267950). This is a recurring failure that affects safety and comfort during high-temperature seasons. I believe this is a manufacturer defect and request a formal investigation.
My childâs seat buckles are still not locking into place. Iâve contacted Nuna and their response was they needed 24-48 hours to find a solution as Iâve already donât the seat recall solution. But they told me I canât use this seat for my child. So Iâm stuck without a car seat until they find some solution for me. I found this issue because my child was able to move the seat straps on his own, while I was driving down the highway.
