Mine had a noise like this and after 2+ months of troubleshooting my dealer followed my recommendation and replaced the rear driveshaft. Noise was gone. There was a recall back last summer for early 2019 builds but somehow my vin didn’t qualify for the recall. But the rear driveshaft was bad anyway. Unfortunately the dealer replaced lots of other parts first including an entire new rear axle.

Thank you Paul. Was you noise all the time or does it occur only at certain speeds? Mine begins at 40 and ends at 50. During that 10 mph range, I can actually change the noise pitch and/or make it go quiet by letting up on the gas or quickly giving it gas. When I'm slowing down from lets say 60, the noise will return at 50 down to 40 and then quiet.
Thank you, Gary

Yes that was very similar with mine. It was only from about 50-65 on mine and only made the noise when I was on the gas. When I let off the gas it stopped. One way to check is to remove the rear driveshaft and drive in 4wd (making it front wheel drive). That’s how I proved it was the issue to the dealer.

Hi Paul. Was the u-joints making the high pitch whine noise? Thank you, Gary

Not sure what was causing it. The recall was related to failure to add grease in manufacturing process. Not sure where but I assume u-joints.
