NHTSA Complaint #11570701 — 2017 KIA SORENTO

I have had engine misfiring and brought my car in 3 times for this. Had the KSDS update performed in 8/2023 and resolved for about 6000 miles and happened again. I was driving on the highway, and suddenly my speed just slowed down and could not drive more than 45mph. I have had high oil consumption that I have complained about for several years, and was not offered an oil consumption test, that I was not aware of such a test. I did make an appt for the test, but my engine failed before the appt. I have been using 5 quarts of oil about every 1300mi. My low oil lamp has not come on many times, and will only flicker when making turns, only to find my oil level was bone dry. I have had oil changed at regular intervals. Took my vehicle to Kia dealership and there was no compression in one of the piston cylinders, part of spark plug melted off into the engine, and have "engine failure" diagnosis. I Have had the piston rings replaced in the recent past. I had initially brought my vehicle into Kia dealership at 99,600 mi knowing that engine was under warranty. 6000 miles later, engine failed and now Kia dealership is telling me the extended warranty does not cover for it. Estimate cost to replace engine is about $10,000 per Kia dealership estimate.I was under the impression it would be covered. I was not offered a loaner vehicle, since it is not covered under warranty, making me a low priority to get a loaner car to use in the meantime. I am the only and original owner of this vehicle. There has been no oil leaking in my garage, where is it all going?
