Most Recent Complaints
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)
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.
While driving under normal conditions and normal operation, the engine lost power, began using excessive fuel, the inside of the vehicle smelled like fuel and white smoke began pouring out of the exhaust.
Driver Side door stuck in the closed position. Electric Motor does not work.
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
