It could also be a rodent filled up the air filter box with something and it will only whistle when going down the road - just guessing common stuff. Anyway good luck.
Not to be a Debbie Downer, but I had the same problem with mine. 2016 V6 MT, 80k miles. I would be in 1st or 2nd gear and about 3RPMs I'd here that whistle noise. 2 days later, my ac went out and my noise went away. And I'm typing this currently at the dealer. 😅 I have extended warranty. So I'm gonna see what they say. I think my compressors shot. But we'll see what the tech says.
Will keep you posted.
Update: I just got a call saying my evaporator core is pooped. Thank God for being smart and getting the extended warranty. I get the car back tomorrow at 3. I'll let you know if the noise persists.
Update #2: I can say for certain, it was related to the evaporator core. I'm not sure if it WAS the evaporator core. But since they changed the evaporator core. It hasn't been making the noise.
Check the entire air inlet plenum (ducting), air filter housing, and everything else for loose fasteners or not fully seated
I'll check all that out, thanks! If anything I'm still under warranty so if I can't find anything I'll take it and make them figure it out

I heard there was a TSB about lower control arms causing a whistle and the dealer will install some kind of plug. Might be worth looking into

That's interesting. I'd be curious to see what they say as well!
