Only hear it at very slow speed. Very faint. Only those with OCD like me would hear it without being told to listen for it. I hear when you are coming to a stop. Slow whirl sound. Doesn’t appear to be engine. Doesn’t change with AC blower speed. Stops when I stop and it’s not heard above that 1-3mph speed. Anyone else?

I know what you're talking about, mine does it even more so when in reverse (backing into the garage). I'm about positive it's just the driveshaft area, perhaps the differentials and/or transfer case. Mine has new fluids in all of those, along with the transmission, and it still does it. I wouldn't worry about it. There are a lot of things rolling/spinning/clunking/meshing around to get it to move.

What I do hear when in the 20mph zone are the turbos spinning. Say taking it easy while leaving my neighorhood, I can hear them sort of spinning even though no boost is being applied. I kind've like it..

PS: At least you don't sound like George Jetson in your electric space ship!

I tend to agree with your thinking

2024 2.7L with 12,400 miles. Was idling this morning and about hour four the idle pitch changed with a slight whirring noise. Only heard it when the songs changed. And now I can't let it go. Gonna have to chalk it up to the new turbos and turn the radio up while trying to push it out of my mind.
