STRUCTURE:BODY, UNKNOWN OR OTHER
Vehicle: 2022 Kia Carnival Component: Liftgate — right-side support/strut (shoulder) failure Safety Issue: The right-hand side trunk strut/support has completely broken, causing the liftgate to drop unexpectedly. The trunk will not stay open and can fall abruptly during use. This creates a significant safety hazard for adults and children standing underneath, and while loading/unloading cargo. There was no prior warning or misuse. The failure is structural and sudden. Resulting Risk: Risk of head/neck injury, especially for children or anyone attempting to open or hold the liftgate. The sudden drop makes the rear of the vehicle unsafe to use. Request: Investigation into whether this is a defect affecting other 2022 Kia Carnival vehicles.

ENGINE AND ENGINE COOLING, FUEL SYSTEM, GASOLINE
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.

FUEL/PROPULSION SYSTEM
In October 23, 2025 I started to notice a fuel smell while I was driving the vehicle. The smell of fuel seemed more strong while I had the air conditioning running.I would shut off the AC and put the windows down. There was no leaks of fuel on the ground or close to the motor. No check engine light or messages was displayed on dash at anytime. My concern was that I’m constantly driving my small children in car seats to and from school, sports, and appointments the smell the fumes will cause headaches or worse car will catch fire were we would need to make a fast exit out the vehicle. So I made an appointment with Kia of Stockton and they scheduled me for 10/29/26 at 9:30am. Kia first diagnosis was undetermined and charged me another $315 just to keep diagnosing on top of there first fee of $315. Kia discovered after removing the foam that protects the fuel rail the leak was coming from fuel injectors and fuel rail. Fuel injector leaking where injector inserts into rail. Repair was needed due to failure of fuel rail housing not sealing properly. Kia also replaced associated components with the fuel rail clips, bolts, flanges, high pressure sensor, foam, and injector wire harness. According to Kia there tech found short in the injector harness.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
I live in Alabama. Temperature here is 34 degrees so far in the morning. My check engine light is on. I have taken it in and had diagnostics and they can't find a code or code history. My heat and AC do not work properly if the ambient temperature on the cluster doesn't show up or is not correct. 72 degrees when it's not working right will run you out of the car it's so hot. The cluster currently says it's -15 degrees outside and has the snowflake beside it. I am scheduled bc they are booked out at the dealership to have diagnostics run on 11/14. I don't know if it is wiring, ambient temperature sensor, max air sensor, HVAC module (dealership had previously cleared water out of the module and then replaced the module, initially when they couldn't find the problem they disconnected the battery and reconnected to reset and clear the code). The dealership in Auburn Al has addressed all the issues and done all the services, updates, and trouble shooting. I'm having to run three different temps in the car and crack the windows when I need heat and AC just crack the windows and adjust the three temps again. I feel like I'm just getting a quick fix each time I go instead of the problem being resolved for good. This has been an ongoing issue especially when the temperature changes (seasons) or fluctuates (throughout the day). I've listed below the most recent start date. I would have to contact that dealership to get the exact timeframe that it ALL started.

ENGINE
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.

STRUCTURE
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.

POWER TRAIN
URGENT SAFETY CONCERN/ISSUE On [XXX], while driving my 2026 Kia Carnival Hybrid SX Prestige, it lost all power without warning, leaving me unable to accelerate or control the vehicle. This created an unsafe situation as I was traveling at 40 mph when all power was lost. What happened to me was a serious safety hazard. The vehicle was brand new with only 1351 miles at the time. Several warning lights came on including the hybrid system warning light. The vehicle was not drivable; there was no power at all. I had to tow the vehicle to a Kia dealer where it took 17 days to repair with a new power module. On [XXX], (after the vehicle was repaired), I was driving the vehicle when the POWER alert flashed on the dashboard. I did not lose total power yet, but the literature advises that I take the vehicle into the dealership asap to have them look into the Power warning light coming on. I have an appointment on September 18, 2025. I have reported my issue to Kia customer service, and the dealership is aware of what is going on. I believe what is happening, (the abrupt loss of total power while driving) may be a widespread defect affecting the Carnival hybrid system in 2025 and 2026 model years. This is a serious safety issue that need corrected before someone is killed or seriously injured. Total loss of power at 40 mph or more cannot be permitted to happen. There should be some sort of safety bypass whereby the gas engine totally engages to the exclusion of the hybrid system, so total power is NOT lost at High speeds.

I went to use my vehicle horn when another driver pulled out in front of me and the sound was way off...it sounded like a clown horn. I subsequently took to the Kia dealer where they diagnosed that one of the horns failed and it was replaced under an extended warranty with a deductible payment. The failure of the horn compromised my safety and the other driver's as the other driver may not have heard my warning that my vehicle was where it was. There was no warning that the horn failed until I went to use it.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
On August 23, 2025, I purchased a certified pre-owned Kia Carnival. Within hours, the vehicle had a severe fuel leak that produced a strong gasoline odor. Driving it made me sick, and I feared for the safety of my three children in the vehicle. A Kia technician later confirmed a crossover fuel line leak so severe that he became ill while inspecting it and feared the vehicle could explode. Even after repair, the gas odor persisted. This vehicle was sold to me in unsafe condition, and I believe this may represent a larger safety issue that needs investigation.
