Whining type noise when giving and laying off the gas.

I was wondering if this sounds familiar to anyone. I have a 2018 Off Road automatic that I have had for about 6 months. Recently I noticed that when going around 40-50 mph and I lay on the gas I hear a whining type noise from the rear passenger side. It started about 2 weeks ago, but only happens when I am moving, not when first getting moving.
I apologize for the lack of detail but I cannot think of a better way to put it.

 

You’ll drive yourself nuts trying to figure out every little noise your truck makes.

My advice is keep good maintenance and turn up the radio.

 

Thanks, it just caught me by surprise. Coming from a Jeep those noises usually mean bad things and lots of money.

 

There is a TSB for the howling rear, sounds like that may be what is going on with your truck.

Thanks! I have my second Mainemainte to be scheduled, looks like time to address it with them.

 

my son or wife always whines from the passenger side when I lay on the gas...lol

 

Ha! Well done.
I scheduled my next service for this Saturday, they will take a look then.

 

My truck stumbles when I lay on the gas and howls when I go off the throttle

 

That was it. They are ordering the parts

 

Good deal, that should hopefully quite it down enough to where you no longer notice.
