Low "static" noise when vehicle is in motion & radio off

[JGCanada]

2020 1500 Bighorn - I'm hearing a low noise that sounds a bit like radio static or a crumpling plastic bag coming from inside the cab when I'm driving, as I slow down and stop it does too. Can still be heard when radio is off.

Do you have a Hemi? Could be the active noise cancellation.

Yes I do, I thought that as well. Are you aware of anyway to fix it? Had the truck almost a year and this just started in the last couple days.

There is a TSB which is a software update to fix the problem. Other solutions are using a bypass cable or disconnecting the microphones

I have the same issue. I already disconnected the ANC and I still get some static noise coming from the front speakers. Very annoying.

Hmm, ANC is from the rear speakers

I occasionally get this from the front speakers also. The first time I heard it I thought it was starting to rain.

Wonder what it could be. Almost sounds like the noise when the ground isn’t making great contact and it wines.

Any updates from someone who might have fixed the issue? I’m about to plug in my ANC mics back and see if it helps any. I usually hear it when coming to a stop and as the truck downshifts from 4th to 3rd and into 2nd. It’s getting annoying.
