07 Yukon-Noise from engine at shut off

[andydallas]

Just noticed when I turn off my 07 yukon there is a clunking noise from the engine area. From what I can tell, it seems to be coming from the upper engine area..kinda sounds like its coming from the throttle body. Anyone had this issue or heard of it?

I barely drive it. Haven't driven it for 2 weeks (have a company truck) and I decided to drive it today. Didn't have gas so turned it off and thats when I heard it. Got scared to drive it so left it there.

Any help will be appreciated.

Anyone ever heard of this ... I have a 2010 that it sounds like setting an old emergency brake when I shut the engine off ... Thanks
