NHTSA Complaint #11661218 — 2018 KIA SOUL

My engine under, the 2018 KIA Soul Engine Recall, first problem was on October 2023 when it arrived at the dealership with 'no oil'. The mechanic said for KIA to replace the engine. At this time they also found 'sludge' for the first time. I had done my oil changes at the dealership and the most current was August 2023; 2000 miles prior. KIA extended my 100k miles engine warranty to 150k miles. Since, I have experienced excessive oil consumption and firing of the engine. In December 2024, the engine light went on. The KIA mechanic said the engine must be replaced. This time I had a problem finding two maintenance receipts. KIA refused to honor the warranty. The dealership refused to work more on the car. In March 2025, the car began to fire large bangs, then much smoke and the engine seized. What if I was driving on a busy street when this happened? What if the car caught fire? I towed the car to the dealership. KIA manufacturer refuses to honor the engine warranty. I explained to KIA my car has documented engine problems. The sludge found is part of the engine problem. The car uses excessive oil, the high burning is coagulating in the bottom of the engine causing the sludge. I have followed the scheduled maintenance in the owner's manual. I have been harassed, badgered, called names at the KIA dealership who wants me to take my car away. I told all of them I have a car with a well known and documented engine defect that they must fix. I read the NHTSA 23V-099 recall. My KIA Soul has experienced similar problems according to the descriptions from the KIA mechanic. Because my car does not fall within the specific car description KIA keeps turning me away. I am driving an unreliable and unsafe car on the road. We cannot allow KIA to continue to sell unsafe cars they have no intention to correct. Another problem that began after the October 2023 break is the car has an error that reads, '...the battery is on'. I have replaced 3 Die Hard batteries since. Thank you.
