Sorry to repost! I went to the dealership where I bought my 2013 Hyundai Genesis 2.0t and they said it was the wastegate Actuator that makes this noise when turning the engine off and that it is normal? What do y’all think? It’s the noise right after the engine is cut off. It’s the weird squeaky noise that you hear. Hope this video helps?! If not I can make another one, it only happens after the car has been driven and warmed up. Thank you for your help.

I have the same rattle type of noise and Hyundai told me its the waste gate, that its Normal wear and tear but they all do it, eventually. They also suggested I install a Blow Back Valve which should tske care of the waste gate noises.
