Humming noise when accelerating

Hi I am new hear I have 2014 Jeep cherokee north edition 3.2. I had so many issuewith my cherokee and now i have noise issue. everytime i drive around 45 km/h i start hearing sort of humming noise and car stops noise stops too. I went to shop and left my car for 3 nights but still hear noise. It is like wind sound or belt running sounds. it was from rear side and shop foreman heard noise but i hear from front now again.
Anyone had same issue? Please help me out. my warranty will be expired soon.
Thank you

Sounds like the drive shaft bearing or whatever it was I had to have replaced... well, then again, mine sounded kindof like whirring or slight grinding...

I'd check the wheel bearings.

Sounds like the issue I and a number of others had -

I took it in and they replaced the PTU
Adios PTU... at 25k

I drove off the lot and the sound was still there. Total fail on them for giving it back to me with the exact same issue. I turned right around and gave it back. They then decided I needed a new drive shaft.
Need New Driveshaft...

This seems to have fixed the issue. I have not had the noise since it was replaced.

I also had this issue and have a driveshaft on back order right now -- they indicated it was the steady bearing that has failed on driveshaft
