On May 18,2021 my Kia Sorento SXL AWD V6 caught on fire for unknown reason. I was driving with windows open sunroof open and cruise set. Not a single warning light or any weird sounds at all. A car pulled up yelling at me that my car was on fire to pull over off the interstate. I saw nor smelled any smoke anywhere but then I saw a cop had someone pulled over so I figured it would be safe since I was an alone female and it was car of males yelling at me to pull over. As soon as I got out and walked to the front of the car there was still no smoke but flames and what I assumed was plastic dripping from the entire underneath. At this time flames shot out from all around the hood and up the windshield as it instantly shattered. …
I have been having excessive oil burning for months. When I took it to the Kia dealer, this was a known issue. They told me I'd need to continue to regularly top off my oil (way over the recommended amount) or risk my engine blowing. Just over the warranty at 102,114 miles the car seized. The repair shop diagnosed it as a valve/cylinder head issue, but the engine has not been working as it should since long before before the 100,000 warranty mark. It is documented at my Kia service center. My car is useless, not even drivable now. This is a known issue (the burning of oil) and Kia isn't upfront about this issue. While there was a class action lawsuit for other engine issues in this model, there is no accountability for the issues we face. My car is worthless and at only 102k miles. I've taken great care of this vehicle, but it is poorly made. …
