NHTSA Complaint #11669347 — 2019 HYUNDAI SONATA

Car has 39,495 miles. First owner of vehicle. Have advised dealership since 2024 that there was a oil issue as i have only went to them for oil changes. I advised that as they can see the car is barely driven and the oil is disappearing. They claimed nothing was wrong and made me pay for a oil change again. Come this year, I advise again there is a issue, they tried to have me pay for a oil change again and I advised something else needs done. They argued I was not the first owner and the car was not in warranty however I bought the car from their lot and I am the original owner. Then they stated I had to pay for another oil change for the oil consumption. Then they claimed they would just do the oil consumption and then to drive 1,000 miles and bring it back. After the oil consumption engine light is on. I drove 1,000 miles, brought it back and the engine failed the test. The dealership changed the engine. 5 days later engine light is on, car is stalling and brake locked up, then car would not start and was smoking under the hood. Car was then towed to the dealership. They claimed nothing is wrong and they reset the code for the engine light to go away. They stated evap code was on but was not persistent so it's fine. Few days later engine light comes on again and once the car has been running, you shut it off go to start it again it won't start unless you have it sit for a while. I Take it back to the dealership they point next to the engine saying a purge valve, but the wants money for a diagnostic. They do the diagnostic and still provide maybes, as they claim the filler neck is rusted and corrosion. I take the car to another place who states the filler neck is fine.
