NHTSA Complaint #11492553 — 2016 HYUNDAI SONATA

The engine light has come on and I have done extensive repairs on my vehicle since January 2022. No warning signs showed prior as I have kept up with maintenance on the car since the 60,000 mile marker. The valve gasket cover was replaced as the engine was smoking due to an oil leak. A pipe was repaired due to the leak. The engine camshaft position sensor was replaced. There is still issues with the engine after replacing the CVVT cover and plugs. The spark plugs have been replaced. If my car stalls or blows on the highway, this can cause a major accident putting myself and others at risk. I have done multiple tests with Hyundai dealerships and Firestone and AutoZone and no one can tell me what the ultimate issue is with the Sonata.
