I just found this thread in my "subscribed threads" list. Those of you that posted in here, are you still having the whistling issue? I am wondering if it was a break-in issue as I have not heard the whistling in a while and I just passed 20,000 miles.

Can anyone else confirm if their whistle went away? I've got a 2016 5.0 with 2000 miles on it that does this. Wondering if it will go away or if there is a solution. Doesn't seem to be causing any issues, just annoying as hell.

I've had/have the same issue. Mine is a '16 XLT 5.0 with about 10K miles and I'm still hearing the same high pitched whistle...I only hear it with the windows down. I've had 3 tech's in the truck with me at the same time listening for it...I heard it but none of them did, so at this point I've given up. I know it isn't just me, as my wife and kids hear it when driving...

10000 miles now and still happening. Anyone have an update?

Multiple people have posted in other threads that it's the throttle body.. My truck does the same thing and it's freaking annoying with windows down.

I know this is an old post but I just bought a 2016 5.0 and I hear the noise. At first I thought it was the radio since it is faint with the windows up, but today I had the windows down and heard it loud and clear. Did anyone find a fix for it?

My 2017 5.0L did NOT make this sound, my 2018 5.0L makes this exact whistle. Dealer said it's the turbo charger... I said it's a V8 and he back tracked.

I installed a 2017 5.0L throttle body and immediately got check engine light and misfires upon startup. They must have changed the part so I am installing a new 2018 OEM throttle body this week and will report back.

I can't hear the whistle at idle, but I put a mechanic's stethoscope on it and I can hear the whistle inside the TB without accelerating while in park.
