Help, please. 2015 Yukon whine - video included

[Youtawn]

Our 2015 Yukon with 60,000 miles just started having a problem.  It whines when I push on the gas, past about 70 mph and gets louder as I approach 80 mph.  It stops when I let off the gas, but starts again the second I press it.  Any ideas or help would be appreciated.

Couldn't open your link to hear, but the way you describe it I had a vehicle that did the same thing.  The rear differential had to be changed out, twice.

Did yours only make the noise when pressing the gas or whenever the wheels were turning?  The sound is loudest in the front seats, but I guess it could be travelling up the driveline...?  

 

I added a youtube link for the video in the OP.

Watched your video.  When my rear differential would whine it would do it every time I pressed the gas pedal, it was like you could hear the throttle as you gave the car gas.  I've heard the whine when turning the wheel, but most times it was because the power steering fluid was too low.  Your video is not the power steering.  I think the rear diff is still is under warranty, give the dealer a call and ask.

Thank you, I'll give them a call.

Here's your fix. I have  2018 Yukon with the same noise and they differential was changed but it did not fix it.  I don't know what the dealer is going to do next but there are several threads on this site with similar issues.
