Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
2018 Kia Sedona lx stalled while my wife was driving on the highway. No warning lights were on until the vehicle lost all power. Luckily my wife was able to pull the car safely to the side. The vehicle only has 36960 miles. Brought vehicle to the dealer and they said engine was seized. That Kia would not attempt a repair unless I gave copies of oil/oil filters from oil changes that I performed. I did not have these so Kia is not honoring the warranty. I changed the oil every year regardless of the miles. Did not miss. The oil is clean as I just changed the oil a couple months ago. Someone could have been killed. We got that van for our disabled adult son. Thankfully he wasn’t in the vehicle. We’ve been ripped off but at least my family is safe.
The vehicle is a 2018 Kia Sedona with approximately 122,000 miles that experienced a catastrophic engine failure resulting in complete engine seizure. The failure has been identified by an independent mechanic as a rod bearing issue. The engine remains intact and is available for inspection upon request. The vehicle is currently not operational and the battery has been disconnected. This vehicle is a family vehicle that regularly transports our four children. At the time of the incident, our [XXX] child was in the vehicle with us. The failure created a serious safety risk. While traveling on the highway, the vehicle suddenly lost power without warning, creating a hazardous situation in active traffic and increasing the risk of a collision. The presence of a young child in the vehicle further heightened the severity of the safety risk. The issue was preceded by a light tapping noise that began approximately 10 miles prior to the failure. Within about one minute before total failure, a loud squealing noise occurred, followed immediately by complete engine shutdown and loss of power. There were no meaningful warnings that would indicate imminent catastrophic failure in time to safely prevent the incident. The problem has been confirmed by an independent repair facility, which diagnosed the engine as seized due to internal failure consistent with rod bearing damage. A Kia dealership and Kia America have both been contacted and declined responsibility for repair. The vehicle has been regularly maintained, with routine oil changes performed as expected. The most recent oil change was completed approximately 2,000 miles prior to the failure. Insurance has confirmed this incident is not covered, as it is a mechanical failure and not the result of an accident or external damage. The vehicle has not been physically inspected by the manufacturer. Police were not involved. This type of failure is consistent with widely reported engine defects across Kia vehicles i INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
The contact owns a 2018 Kia Sedona. The contact stated that the air bag and the check engine warning lights were illuminated. The vehicle failed to start and was towed to the dealer, where it was diagnosed with alternator failure; however, the battery was replaced. Additionally, the contact stated that after his wife had pulled into the driveway, the instrument panel turned blank, and the driver noticed smoke coming from under the hood. The driver turned off the vehicle, and the vehicle cooled down. The contact stated that upon attempting to restart the vehicle later in the evening, the vehicle failed to start. The contact opened the hood and noticed that unknown parts had melted. The vehicle was towed to the dealer, who informed the contact that the battery terminals and an unknown control module had melted due to an electrical failure; however, the vehicle had not yet been diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 90,000.
I was driving my 2018 Kia Sedona on [XXX]. I had all 4 of my kids with me in the van, I heard a click, click, click, then the car went dark, in the middle of the road no warning nothing. There was no light or anything that came on as a warning. It just died. It was scary to go through that with my kiddos. We are devastated as the car is only 6yrs old and it wont work at all. Had it towed to my local auto shop. They said the engine is defective and needs to be replaced. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
In 2022, our airbag light came on. On 5/10/2022 am Airbag recall was issued and it was fixed. The airbag computer/module was fixed. We got into an accident in August of 2022, and our airbags never went off. And the airbag light has never shut off since it was “fixed” May 2022. It’s now October 2025. They said nothing was wrong with it, after bringing the vehicle in multiple times. And now after bringing it in, again in August 2025, they said the entire passenger airbag unit needs to be replace and isn’t related to the airbag recall. It’s $800+ and Kia won’t do it since the warranty has expired and it’s “not related”. Still fighting with them over it. As the airbags recall in 2022 included a defect where the Airbag Control Unit (ACU) cover can contact a memory chip, potentially deactivating the airbags. This issue affects a range of models manufactured between July 2016 and January 2019 and can result in the airbags failing to deploy in an accident. Worst customer service and vehicle I’ve ever owned.
Since shortly after buying the van we have been getting airbag warning lights. Just about every part of the system has been replaced, but the airbag light still comes back on. Just got the van back from the dealer today for the 9th time, and after about an hour of driving, the light is back on again.

Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.
From owner reports, verbatim
I have the air bag indicator light and the diagnostic codes consistent with NHTSA Campaign Number 19V109, Kia Recall Number SC175. The recall mentions the wiring harness being damaged and my harness is damaged, with two wires severed. However, because my vehicle was manufactured 2 months after the recall cutoff date, Kia believes this recall does not pertain to my vehicle. I believe otherwise.
The contact owns a 2018 Kia Sedona. The contact stated that while the vehicle was parked in the street, the smart lift automatically engaged and the contact was tramped in between her vehicle and another parked vehicle. The lift does not disengage when sensing a person when lifting or descending. The contact stated that she heard the censor but could not move. The vehicle was not taken to the dealer nor repaired. The manufacturer was notified of the failure. The failure mileage was 48,000.

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
There was a fire under my minivan as my husband was driving it, creating smoke and flames. He lost power to the van and had to coast to the right side of the highway where he came to a stop with the flames occurring. This is the family vehicle and I have small children. We had no warning lights or any indication that there would be a fire in my vehicle as the van had been running smoothly, and I had kept up with all recommended maintenance (see Carfax report). On July 31st, I was told by Kia America that there was a fire in the engine compartment and that it was inconclusive and they could not determine what started the fire. On August 15th, my father and husband went to Castrucci Kia (where the car was) and were shown that there were holes in the engine block, and the service representative Brandon stated that the engine failure had probably thrown some of the rods causing the holes in the lower engine block sparking a fire when the leaking oil hit the catalytic converter. My insurance was involved, but I was not able to obtain a settlement from them, but I kept up on all maintenance and adherence to Kia guidelines and my engine unexpectedly failed and caught on fire. I was told I would need a new engine at an approximate cost ranging from 12,000 to 15,000 dollars. I believe that my 2018 Kia Sedona's 3.3 L gasoline direct injection engine was manufactured defectively resulting in catastrophic engine failure, APPARENTLY puncturing the engine block, causing engine oil to leak and ignite a fire. Our attempts to address this critical issue with Kia have been met with significant resistance and delays. It appears that Kia refuses to take responsibility. There has been an escalating number of safety complaints and instances directly linked to the 3.3 L Kia V6 Lambda II engine. I appreciate your assistance in resolving this issue with KIA AMERICA and the local KIA service center where my vehicle is located
IF YOU REMOVE PRESSURE FROM THE ACCELERATOR WHEN THE TRANSMISSION WANTS TO SHIFT SOMETIMES THERE IS A LOSS OF ACCELERATION AND THE VEHICLE WILL START SLOWING DOWN WITH THE ENGINE RUNNING WITH NO ENGINE WARNING LIGHT COMING ON. THIS INTERMITTENT PROBLEM HAS HAPPENED WHEN THE TRANSMISSION SHIFTS AT APPROX. 2, 9, 19, 25, 40, 55 AND 62 MPH. WHEN THIS HAPPENS THE ACCELERATOR BECOMES DISABLED, THE VEHICLE STARTS TO SLOW. TAPPING THE BRAKE WILL SLOW THE VEHICLE FASTER AND THE ACCELERATOR IS OK/ENABLED.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.

The headlights are auto leveling based on load. Although there is no load in my vehicle the headlights do not shine out very far in front of the vehicle. There is a very distinct cut off line on the road. There is no way of adjusting them. This is very dangerous because you cannot see whats ahead of the vehicle in the dark. The attached photo is the headlights shining on my garage door.

Our 2018 Kia Sedona SXL caught on fire in the engine compartment while driving. IT almost killed my wife (driver) and my 4 year old son. Car had been driven only 2 blocks after picking up my son from daycare. The car started to produce black smoke incessantly from the engine compartment that made visibility almost impossible. Bystandards were waving with their arms up and trying to warn my wife and she managed to stop in a parking lot and run away with my son. Car got very hot. Despite of keeping regular maintenance, car has had a myriad of issues: electrical components going off and not working anymore (cruise control, rear view camera, navigation system), booming sound from air conditioner like an old airplane is inside the cabin..etc.There were no warning lights suggesting any problem before car caught on fire. Please help.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
Engine failed…driving down the road with five small children and without warning all the lights came on and started smoking, leaking fuel, power doors failed, steering, acceleration and more. We had to have the car towed to a shop. A when looking into what’s happening apparently many others are having to spend thousands to fix this issue and I’m afraid that’s where we are. An investigation needs to be opened as this is clearly an ongoing issue for many families

Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
My [XXX] son pulled the seatbelt so tight it got wrapped around his neck. When I pulled over to unbuckle it, it was stuck. I turned the car off and on again to try and loosen it, but it didn't work. In the emergency, I had to cut the seatbelt with scissors. It's the passenger seatbelt in the second row, next to the window. I reported the incident to Kia in Puerto Rico by phone. They never called me back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Visibility

From owner reports, verbatim
WE ONLY HAD OUR VEHICLE 5 MONTHS AND MY HUSBAND WAS SITTING IN TRAFFIC DURING A SNOWSTORM AND THE WIPERS STOPPED WORKING. WE TOOK THE VEHICLE TO THE DEALER AND THEY TOLD US IT'S NOT A MANUFACTURER'S DEFECT SO WE WOULD HAVE TO PAY $507 OUT OF POCKET TO REPLACE THE WIPER MOTOR. THEY CLAIM THAT HAPPENED FROM SOMEONE MOVING HEAVY SNOW OFF THE WINDSHIELD WITHOUT CLEARING OFF THE WINDSHIELD FIRST. MY HUSBAND HAS AN ICE SCRAPER AND HE TOLD ME HE USED IT, NOT TO MENTION, HE KEPT THE HEAT ON THE WINDOW THE ENTIRE TIME. I THINK IT'S RIDICULOUS FOR THEM TO HAVE US TO BELIEVE THAT ON THE FIRST SNOWSTORM OF THE YEAR, THE WIPER TEETH GOT RUINED FROM SNOW, WHAT'S THE PURPOSE OF THE WIPERS? IT HAS BEEN ALMOST A WEEK SINCE WE LEFT THE DEALER AND THEY HAD NO CONSCIOUS ABOUT US DRIVING OUT OF THERE WITH NO WIPERS. WE CANNOT AFFORD $507 SO OUR FREEDOM TO DRIVE OUR BRAND NEW CAR WHENEVER WE WANT IS LIMITED UNTIL WE FIGURE OUT WHAT WE CAN DO.
