4knucks - If you (or anyone) are experiencing lingering headaches and pressure, you may have a condition I am familiar with, external pressure (associated with these vehicles for example) will irritate the condition. I think I can help, send me a PM if you want to know more,

Yeah I would agree wrench, you are missing something. De-energizing ANC as you put it may not be the answer. Look at the cotton balls and tape, it decreases the pressure by 95%, ANC was not disabled. I never set out to find the answer, always defaulted to GM owning that responsibility. So, you'll just have to do the research and figure that one out.

Hey - I mention the MP in post 630, but that's not a silver bullet. The silver bullet is GM issuing a fix, so we are not there yet. In the meantime, the thread may have lost some steam awaiting 20sierra14's comment on a PM I sent him on a viable option (15) for the 2 piece MP. 20sierra may be overcome by events and may not be able to engage option 15 and the folks having the pressure and buffeting can't wait. Respectfully recommend some other folks get on board and make something happen versus waiting on something to happen.

 

I would like to send someone the actual 2 piece MP, but I would need precision mic measures. Without the measurements, here is option 15; go to the store, pick up a pair of dense foam ear plugs (EP). Remove the grille then cut the EP down in circumference to fit within the inner ring of the O ring, then compress the EP into the space. Keep the EP compressed and take about a 1" piece of duct tape and cover from one end of the outer O ring to the other keeping the EP as compressed as possible while taping. Cotton balls should not be needed since option 15 isolates the mic to the maximum extent. Replace your grilles, exterior tape will also not be needed. Give it a test drive and post results

Mortman - The intent of the MP is to plug the mic versus the grille, but I think I'll order me a pair and see how I can use them. Although when I started down this rabbit hole it was to modify the grille, that's still not off the plate. Mold-able silicone, does it hardened like the silicone used for fixes around the home?

No...they stay pretty pliable. She uses them for swimming so we put them back in the case after her practices/meets. Not sure if they would harden if I kept them in the open. We just pluck them out of her ears and ball them back up. Next practice we roll them out and stuff them back in her ear canal.

Mortman - good to know info, usually silicone hardens if left exposed to air. I'll grab a pair and drop them in the toolbox for later, thx

Those that had the headliner removed, do you know by looking at the work invoice if the dealer used a form fitting foam (FFF) headliner or if they just sprayed or packed foam in as a filler? I went around my truck yesterday and tested my headliner, other than right around the air vents, my headliner fits jelly-tight. It gives the impression that it's a FFF headliner. Someone mentioned before that their headliner was extremely loose fitting. I will pop my vent covers this weekend and look around

 

Also, if you are about to get your headliner removed, asked the dealer what materials are involved with re-installing and how will it be applied.

I have a new 2015 Escalade ESV (purchased October 2015 and built in Arlington) and it started the buffeting sound about 1 month ago. It now has approximately 6000 miles on it. The effect is getting worse every day and physically hurts my ears going over a railroad track. Before we purchased it we test drove a denali and the buffeting was so bad, even the salesman who was riding in the back noticed it and thought it might be the tires, so we got another one and tested it and we did not hear it, but we still ended up choosing the escalade. I have an appointment in 3 days with our dealership (not same dealership as where it was purchased) and I am curious to see what happens after reading all these posts. Not that it matters - but I am an attorney and own a 5 lawyer firm, so hopefully it won't get that far, but this problem seems to be very widespread. If I have missed anything and should be telling them something, please let me know (there are 40 pages on here - so it's entirely possibly I missed something important). Thanks for all the information!!

Update - Car was at the dealership for 1 day - they drove it themselves and heard and felt it. They are ordering the parts for the headliner/roof fix. I'll keep you posted.

I'm off today. Wanted to run over to the local Gun shop and pick up some ear plugs to put into the Mic's.

QUESTION...... I see the pics of the grills. Can you get these out without damaging the grill or headliner?

Hey everyone, I have this same problem. I noticed that the bass was extraordinarily heavy and my ears were killing me. I played around with the base and it was a no go. Then I turned off the Bose AudioPilot in the settings and it seems to have gone away. Sure, I hear more of the outside world, but for in town driving, that isn't bad. I will be trying it on the freeway this weekend, though.

 

I read a huge chunk of this thread and I was wondering if anyone tried this? The stereo isn't so bad. My biggest gripe is with Intellilink. It has a hard time handling Pandora and my iPod. I suspect it needs extra RAM or something.

 

Anyhow, I understand the mics are messed up, but is disabling AudioPilot not an easy workaround?

tobtek - I can't get to mine, but looking at what 20sierra posted, a rubber spatula versus a screwdriver should work without causing damage

I was able to get them off with my fingers... No damage done to the grilles.

So pop'd the three grills off, ran over to the gun shop and picked up the ear plugs for 39 cents. Cut them into halfs, they fit perfect.

 

Sorry to say it's exactly the same. Still has the same tunnel sound over every little bump in the road. Still fills and sounds like it's running out of gas in V4 mode, just lumbering down the road.

 

Anyone else with the 6 liter, experiencing a chirping sound every time you give it gas coming off V4 mode? Sounds like a valve in the exhast system?

 

Was hoping the 39 cent ear plugs in the ANC mic's would be the trick. No dice :(

    • I’m definitely interested to hear the end result here. 
    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
