Odd whirring noise intermittently coming from engine while idling (MY2020)

[MrGrizzly]

Every so often I hear an odd whirring noise coming from my engine while idling. It also causes a mild felt vibration in my truck, which has me concerned. I tried taking it to the dealership but was unfortunately unable to reproduce it when I arrived. Frustrating to say the least.

Any thoughts on what it could be would be greatly appreciated.

That... doesn't sound good. Is the front fan making that noise?
