21 Denali interior rattles.

Are you all getting warranty satisfaction here? I’ve got a dash rattle that is driving me nuts.

Yeah, it does suck. This is my 2nd 2021 Yukon and it rattles now (9500 miles). Creaking sound from instrument cluster. Sounds like the clear plastic is rubbing the hard black trim. Now a rattle coming from where headliner meets the plastic trim that seat belt is attached to (left side of my head). 2nd row seats creak a God awfull sound intermittently.

Then on drive home today I saw a new Yukon Denali getting pulled onto a tow truck while at a gas pump. Lifters I suppose.. Crazy, these trucks really are problematic (I lemon law'd my 1st 2021).

Thank you. Very helpful. We actually found one today in the rear.

The usb-c plug in 3rd row was actually making a surprising amount of noise.

I’ll take it in for the center speaker. That’s exactly where mine is located. If they can repair the center dash rattle then I’m good for awhile.

How did you fix the 3rd row usb-c plug? Pretty sure I have that one as well. There is a lot of play in the right rear usbc plug and the sound seems to carry throughout the cabin.

Dealership had my car for two full days.

They were able to completely fix the rattle in the drivers door when the bass hit, that's been awesome! i am a big music person and didn't even enjoy listening to music with the bass rattle. I can confirm it's completely gone and I had it really cranked. They mentioned they had to tighten some screws in there.

The creaking/rattle below the infotainment screen is BETTER, but it's not completely gone. They had taken apart the entire area and put it back together with vibration removing adhesive.

I will probably take it in again at some point, but I don't feel like doing it now. It's the last and only rattle i'm still dealing with and now that I can crank the music

Just found out the cause. It’s the retainer clips underneath the vehicles heat shield by exhaust. They fall out. I’m missing 2 and have been dealing with the noise for almost a year before anyone could figure it out.

Did your infotainment area stay better? I couldn't take mine anymore and took all of it apart yesterday. I put foam tape everywhere that plastic touches plastic. Took me a few hours. The main problem area was where the chrome trim around the infotainment screen touched the plastic from the climate control. Foam tape between, all is quiet again.

I was about to tear the dash out of my 2023 suburban with this issue but after riding in the passenger seat and tapping the dash and infotainment screen I realized that it was actually the plastic around the rear view mirror and the sound was resonating down to the dash. I put a little foam strip between it and the windshield problem solved. Hope this helps I have seen many people with this issue on Tahoe/Yukon/Suburban

I really really really hope someone from GMC quality control is lurking this thread.

These rattles and squeaks, they matter. GM (all brands) are notorious for being noisy on the inside. If they desire to move up the luxury scale these need to be fixed before they land with customers.

Of the vehicles in the garage, the wife's Denali is the worst for squeaks.

Well, my old rattle in the center console is back. Does anyone know an easy way to remove the large side panel of plastic that is right beside the passenger seat? the long one that meets the carpet? I hear my problem and it is behind this panel....

Here’s a video for installing a wireless charge mat on the center console lid… they take apart most of the center console in the process, so maybe it at least helps you get started?
