The humming sound when my 2016 sequoia engages 4H

[wanronghou]

My 2016 sequoia limited has 2000 miles on it. When this truck is under 4H mode, I can hear a low humming sound on and off from this truck, when the speed is under 50 MPH. I searched this board and find that somebody said this noise will go away with time. But, do I have to take it to dealer to fix it? Thank you!!

It could just be the gears in the front diff "breaking in". If it were mine, and it was making a noise I wasn't sure about, I would take it by the dealer. It's under warranty. Even if they say that its nothing, you have it documented at the dealer that it's making a noise, just in case some happens to it in the future.

Thanks, BlackUSK56. I like your suggestion and would go to dealer for a check.
