NHTSA Complaint #11650841 — 2019 KIA OPTIMA

My 2019 Kia Optima purchased brand new. Kia released a service bulletin on 3/1/22 citing “excessive oil consumption for 2011-2021 Optima's”. I took it in for the "updates" for said service bulletin for the engine and was told that my engine is good and covered now for the life of the engine even past the 100k miles (mind you no one mentioned doing an excessive oil consumption test at this time). On 3/22/24 car had 104k miles on it and the oil light came on. I had an oil change just 2500 miles or so prior. Pulled into an autozone and it was almost bone dry. I put oil in it and the light went off. I took it to Evans Kia and was told that they couldn't do anything because it was past 100k warranty and that they couldn't run the DX test to determine if it was excessively consuming oil as per the recall. Apparently during the recall they did the DX tests if the consumer stated it was burning oil fast or something to that extent. Mine did not get said test, only the upgrade. They should have done the test, but they just did an "upgrade" which clearly did not work. They said since I had the "upgrade", if the engine fails, then Kia would fix it under warranty. Since then, this happened at least 4 more times with the oil light coming on and engine oil practically gone. Each time took less and less miles. I showed up to Kia 2 of those times in 2024 to show them the the oil change date, mileage, and check oil light on. Also physically showed them the oil being almost empty, yet they did nothing but say when the engine dies or "knocks" they can fix it under warranty. One of those times I had it towed but they determined it was the fuel pump, never mentioned anything else. Fast forward 3/15/25 the engine starts knocking and engine light comes on. I managed to drive it to Evans Kia without any accidents. After my car sat for 9 days, they call me on 3/25/25 and tell me there is a "burnt valve on cylinder 4 and the engine will need to be replaced and it is not covered. How? Help!
