2018 Kia Sedona: sudden loss of power

Filed Aug 2, 2026 · Engine · HI

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

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

While driving on the interstate, about an hour into the trip, there was a banging/tinging sound coming from the front of the van. Immediately the van was pulled off the road to assess the situation as there were NO WARNING MESSAGES OR LIGHTS that came on to alert of any problem. Immediately before hearing the noise, the van had a major loss of power going up a slight incline on the interstate. The van threw a rod and had I not noticed the sound and pulled over, this could have been potentially a deadly situation had I kept driving and the engine completely seized up in the middle of the interstate.
