NHTSA Complaint #11612332 — 2017 HYUNDAI SONATA

To whom it may concern, I would like to inform you that I have been experiencing engine power loss and oil evaporation from my Sonata. In fact, I took the vehicle for an oil change in April 26, 2024 and by August 1, 2024, my car was not accelarating and the dashboard was completely illuminated with the engine, air bags and suspension lights. Upon inspection of engine oil dipstick, I was made aware that my oil was missing (evaporated) without any visual undercarriage drips. Therefore, I added 4 qts of synthetic oil to my car recently replaced oil and the car continued without power. Upon connecting a vehicle code reader, it was reported that a spark plug was malfunctioning and I continue with its replacement. To date the vehicle continues to have engine loss of power episodes. Can someone please help as I do not want to die in this vehicle due to a manufacturer's unannounced/undisclosed engine issue. Thank you for your time and consideration.
