Odd Engine Bay Noise

[nardeezy]

I have this reoccurring noise that is coming from the engine bay when the engine is ON. My basic limited warranty has expired but I believe my power train warranty is still in effect.  Click the link below to view the video.  The noise comes and goes like every couple of seconds and lasts for about 1-2 sec.  It’s a high pitch squeal.  Any feedback would be greatly appreciated.  Thanks!  2015 GMC Sierra Denali approaching 56k miles.  Original owner.

Can't see the video for some reason...vacuum pump possibly, others have mentioned the pump being associated with a squealing sound.
