Owner complaint summary

I have experienced chronic and excessive engine oil consumption in my 2021 Kia Sportage S with the 2.4 L Theta II engine. Since around 80,000 miles, I have had to add oil every 2 weeks between oil changes to prevent the engine from running low. My vehicle now requires a complete engine replacement, estimated at $10,000. Despite regular maintenance and oil changes (documented by Express Oil Change in Pinson, AL, with service records at 81,520 mi, 88,215 mi, 94,153 mi, 96,970 mi, 98,902 mi, 101,522 mi, and 105,273 mi), the vehicle continues to lose oil rapidly. Kia and my dealer have confirmed there are no recalls or warranty campaigns for my VIN, even though this issue is identical to the well-documented engine defect affecting earlier Kia models covered under the Theta II engine settlement. This defect creates a serious safety risk, as the engine can run dangerously low on oil between services, leading to engine failure or stalling while driving. I am currently out of work recovering from surgery and cannot afford the $10,000 repair. I am requesting that NHTSA investigate and expand the existing Kia engine defect recalls to include 2021 Sportage models using this engine.
