2015 Denali = VERY ANNOYING Electrical "Jingle" Noise LF Dash

[hosseface]

Just picked up my 2015 Denali yesterday - LOVE IT.

However, it has one VERY VERY ANNOYING problem.

At speeds 1-70 ish - it has a electrical high frequency type noise coming from the LF of the dash. Almost sounds like 2 necklaces jingling together. It is one of the most annoying sounds I have ever heard.

Anyone else heard this? The last thing I want is the grease monkeys at the dealership tearing my dash apart and breaking everything that have to remove in the process. If I had to take a guess - its either the cluster, HUD display module or something in the center stack. It sounds like one of the electrical components making the noise. Sometimes I can even replicate it sitting still. It goes away at about 70 mph and above though.

Looks awesome though.

I don't hear that come from mine ...

Yeah I was afraid of that. Every one I get I always get the privilege of working out the bugs.

It's very hard to describe. Like a high pitch static feedback like noise from something electronic. Hopefully it will go away on its own.

That high pitch sound is what happens in airplanes that develop problems with active noise canceling systems. Just a thought-

Just try to drive over 70 everywhere.





This sucks. I would be so pissed. Hope you get it figured out.

 

[Reels]

I wouldn't be pissed. After a fee growing pains of new model years I expect some production hiccups. They will fix it.

I thought I was the crazy one,
I had the same issue when I drove a 15 escalade.
Almost impossible to explain low frequency noise from left side of the front dash.

Almost think my ears are more sensitive to this type of noise.

I've heard noises like this before and attempted to point them out to others and they always say they can't hear it.

I'm gonna try to track it when I get some time. I think it might be the HUD because it won't do it with just the key on. Has to be running. Maybe like a projector frequency type noise.

*** Edit

At this point I am almost certain it is the HUD module/screen/projector --> whatever is inside the dash that makes it happen. If I sit with the ACC on - no noise. As soon as I start the engine and the HUD fires up - I hear the noise. I have an electronic stethoscope with amplifying headphones at work. I am going to get them and listed to it and see. Will post update.

UPDATE: NOISE FOUND!!! NOT the HUD.( Yeah I'm excited to have found it )

I spent a good part of the afternoon finding that noise. I just couldn't take it anymore. The vehicle is perfect and that had to go. Like I said, I am NOT a fan of warranties and I didn't want someone using a pry-bar to tear my dash apart.

There is a 3 terminal module above the accelerator with GM Part#24269597. Google returns F-SModule.

Anyone have any idea what in the word that thing is? 100% sure the cause of the noise. I can wrap a towel around it to insulate and the noise is 100% gone.

 

[hosseface]

It ended up being the Transfer Case Control Module.

Probably a 1/1 million chance of this but if anyone else has the worlds most annoying noise from the LF of that dash, that is most likely the culprit.

Was it replaced? Did it go away after?

Nice truck. Sorry to hear about the trouble. Thanks for taking the time to share.

Call me crazy...but my new vehicles might as well not have a warranty.

I don't have a dealer that isn't clueless within a 150 mile radius of me and I refuse to let those clowns near my $70K truck. I'd have door dings, scratches, torn up dash panels, greased up seats, etc, etc. I'm just too picky to have anyone touching my truck.

I spent some time after I isolated the noise making sure this module doesn't build up heat (It doesnt) and I made a custom little insulated surround and put it in there and then tied it as far up inside the dash as possible.

Noise is 100% gone now.

Glad you figured it out.. what part of Ga are you in?

Man glad you found it that would've drove me crazy to. Thanks for sharing this information. This is why forums like this are so valuable. I think most of us would like to try to fix it ourselves rather then taking it to the dealer.

Is it a super high pitched kind of gingly or squeaky intermittent noise? If so, i'm hearing it in my newly delivered 2015i escalade premium. I remember reading this thread when i was considering a denali. so THANK YOU if this is it.

Sorry if you already described this, but how do i get access to that part that you wrapped?

Ding Ding Ding.

EASY to get to. Its above and to the right of the accelerator pedal. It just has some plastic clips that hold it in. Take it loose and wrap it with accoustic foam and you'll be good to go. That noise drove me crazy.

Several do it. I was in a 2009 Yukon at work the other day making the same noise.

Oh my Shit. THANK YOU! I'm gonna fit it tonight.

Why are you guys masking the symptom instead of resolving the problem?

Obviously it's not supposed to make this noise so it's a faulty module, and if it's transfer case related it's a somewhat significant one at that. Hosse I get that you don't trust the dealer but if you have enough access to it to insulate it don't you have enough access to it to replace it?

I think the thing is, it's such a high pitched noise (like that you can sense a tv is on in the other room) That it's probably just how it is, and a very small percentage of people can actually hear it, and complain. In a few years my ears will change and i probably wont be able to hear it.
