There are 1 owner-reported suspension complaints for the 2018 Kia Sedonain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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
