Whistling sound at low speed

[19DenaliUltimate]

New here! Just picked up a 2019 Denali with 45k miles on the odometer. Vehicle runs and drives like brand new with the exception of a weird noise coming from the passenger side during moderate acceleration between 10-30 MPH only. Almost sounds like a cold air intake but more high pitched and only occurs at low speed. Vehicle is completely stock.

Window slightly cracked? Even if it looks like it is all the way up it might be 1/16 lower and could certainly cause a whistle.

I had this happen on an ‘05 and it turned out to be the intake tube and filter box leaking at the seam, so the drawn air would sound like a schreech or whistle, only at certain throttle positions and only when cold.

Does your sound vary with throttle position or speed of the vehicle?

If it’s only vehicle speed, it is most likely a body part misfitting and catching air.

I will have to check that out. It does sound like it’s somewhere near the air box.

Thanks for the suggestions!
