Kia
Carnival

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 repairs, the fuel odor had become stronger. The contact stated that the odor had become so severe that she went to the emergency room to be treated for nausea and lightheadedness. The contact was given medication for her symptoms. The manufacturer was notified of the failure, and the contact was given a case number. The vehicle had yet to be repaired. The failure mileage was unknown.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) Kia case number XXX

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.

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 child’s seat buckles are still not locking into place. I’ve contacted Nuna and their response was they needed 24-48 hours to find a solution as I’ve already don’t the seat recall solution. But they told me I can’t use this seat for my child. So I’m 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.

Vehicle vents gasoline fumes into the passenger cabin causing drowsiness, headaches, and impaired cognitive function as well as exposure to a carcinogen. Vehicle has significantly high levels of CO2 inside the cabin at all times (2000-4000ppm) as well as TVOC and HCHO being higher than OSHA allows. Engine temperature gauge does not function properly and sliding doors have closed on myself and my children leaving bruises. If car were to be in an accident it would likely explode. Critical levels of CO2 have caused me to fall asleep while driving on several occasions including on the highway. I have brought car to Kia dealership in Tucson, AZ on 4 occasions, is currently back again for gas smell and high levels of CO2, with no resolution. Dealer manager and service team did confirm gas fumes in cabin and are currently using my CO2 monitor to test for CO2 levels. Vehicle component hasn't been inspected by police, insurance rep., or others. There are no warning lights of any kind on any instance of these occurrences. Images will not upload- email or call.
