hmmmm...

I'm the odd man out here. My new 80th Edition has the 2.0T w/o etorque, but less than 1000 miles on it yet. TBH, I haven't heard anything at all unusual (turbo whine, etc) so far. It's been smooth as glass.

Mine whines but there is no difference in performance. I think it’s honesty just placement of the turbo. That and the aluminum hood having different sound properties than steel we are used too

In comparison my Cummins whined a little but the diesel clack covered most of it but the turbo was right off the side.

The 3.5 ecoboost in the navigator barely makes any turbo noise, disappointingly, but both turbos are tucked down and back pretty far. It also has an under body sound insulator and a fiberglass Hood.

Im late to the party here but personally I think the “whine” from inside and out sounds awesome. Like a jet engine spooling up. Hope mine whines a bit when I get it. Might even change the good decal to Whinicon. LOL. Not really.

I managed to take a video of the whine I have been getting upon acceleration, does it sound like what you are getting as well? Also does yours make that sound when in Park or Neutral?

My gf kept asking me where is the police car and if I'm getting pulled over..

Anyone think this sounds normal? My thread here:

That sounds like radio/speaker interference.

sounds like a dentist's drill. The OP's reminded me of a jet on taxi.

Wow! Is it that loud in the cabin? Mine is not that loud even though it is noticeable with the windows down. My wife asked about it once, but really ours doesn’t appear to be that loud. Be interested in what others think for sure.
Yes, I have a 2019 2.0 turbo & mine does make a noise also especially when I first start it up. Was wondering if it was something with the turbos.

I ran a rental Sahara recently for 3600 miles, everything from crawling Utah & Colorado slickrock to dicing it up with traffic at 80mph on US 70. The motor produces nice power all around with great fuel economy, can climb steep slopes 4Lo/1st. Loved it.
But the intermittent whine is loud & annoying to me.

My 2020 2.0 doesn't make the whine. My 2021 2.0 makes the whine. Neither have e-torque.

My 2019 does not whine either. I think they changed turbo manufacturers at some point; wonder if one whines more than the other?

I took my JL out to my cabin in the woods this week. I did notice when traveling downhill, the Jeep will downshift making the whine louder. I move it to manual and upshift and coast to quiet the noise. Once at the bottom of the hill, I move it back to auto and I'm good.

I have a 2021 Willys 2.0t with less than 200 miles and the whine is very noticeable. Has anyone had their turbo replaced? Anyone lessen or fix the whine? I guess it might be something that I will have to get used to. Glad to hear that other people are experiencing the same noise.
