Starting shortly after purchase, the car lost power and consumed fuel unusually quickly. Over time, the engine began burning excessive oil and now produces a loud knocking sound (bearing knock), indicating internal bearing failure.  These symptoms are consistent with known Kia engine defects (bearing wear / piston ring failure). The defect is a serious safety concern: because of weak bearings and high oil consumption, the engine could stall, seize, or catch fire.  The dealership has refused to repair or replace the engine. I am reporting this as a safety defect and request NHTSA investigation.","products":[{"type":"Vehicle","productYear":"2017","productMake":"KIA","productModel":"OPTIMA","manufacturer":"Kia America, Inc."}]}]}
