   I was driving to work on the interstate and my car went into limp mode almost causing me to get hit at those speeds. I sent it to my mechanic but was told about the theta2 lawsuit so I had it towed to Kia. Was charged $300 and it wasn’t even diagnosed or looked at due to missing oil change receipts. I have since contacted bbb and Kia headquarters to just be told it’s not covered due to missing receipts of oil changes. Even though it’s a known issue with the gdi engine. Was…

    My 2019 Sorento 3.3L suffered high oil consumption followed by a severe oil leak at the back of the head/engine block threads. There is an odor of coolant which smells sweet with no visible coolant leak meaning there is likely coolant seeping into the engine mixing with the oil. I believe this an ongoing engine failure caused from Kia not correcting the issues over many years.
