NHTSA Complaint #11691781 — 2019 KIA SOUL

My 2019 Kia Soul is experiencing severe and abnormal engine oil consumption. This issue requires frequent refilling of engine oil to prevent damage. The malfunction is in the powertrain system, likely within the GDI engine, specifically related to the piston rings. This type of structural defect can lead to a sudden and catastrophic engine failure while driving, which poses a serious safety hazard to occupants and other motorists. The problem has been confirmed by me, the vehicle owner, through the observation of consistent and rapid oil level depletion. Prior to a complete failure, there were no specific warning lamps or messages related to this issue. The manufacturer, Kia Motors, has declined to perform a proper technical review, citing an expired warranty and my status as a second owner. I have opened three separate cases with Kia regarding this matter, all of which were closed without a proper resolution. I am requesting an investigation into this defect by NHTSA.
