2022 Sierra Limited - Dash Squeaking Under 1000 Miles

I live in Wisconsin but two weeks ago drove down to the St Louis area to buy a new 2022 Sierra Limited SLT 4x4 with the 5.3 from a dealer that had good availability and pricing. 200 miles into the 400 mile drive home I started hearing a styrofoam like squeaking noise coming from the lower dash trans tunnel area. It occurred when on roads that were anything but perfectly smooth.  It will ride quietly over perfectly smooth roads. The noise is not tied to ground speed, engine speed, etc. 

 

Since then I drove to Michigan to visit family for the holidays for a couple weeks and it made the squeaking noise the whole 420 miles there (loud enough to hear over the radio at low/medium volume). I dropped the truck at a dealer nearby and am going on business day four of them attempting to find the issue. I found the forum post stating a possible heat shield rubbing issue with the transmission harness but the dealer is claiming that wasn't it. Unfortunately the issue seems intermittent it wasn't nearly as bad when I drove the 20mins to the dealer to drop it off the day after the long drive (making it harder to diagnose). Thankfully the dealer has confirmed that they can hear it and they are attempting to resolve it.

 

Has anyone else had a similar issues and possibly have another idea of something I can have the dealer check? I think they're doing what they can but it's incredibly frustrating that a truck I've had two weeks has been in the shop already for half that time. Fingers crossed I don't have to listen to it the whole way back home and start over with another dealer in Wisconsin.

Thought I'd throw an update out on this. First dealer had it for five days and thought they fixed it but didn't know what was done to eliminate the sound. Well, hit some rough roads again and the sound is back in full force. Going to another dealer on Monday.

Here is a link to a YouTube video of the noise I've been dealing with.

My dash was squeaking last year and the dealership had to re-route one of the main harnesses behind the dash.  They also put loctite on many of the bolts because they have tendency to come undone. The other thing they did was re-route a transmission harness along the console area. My dash has been very quiet since then.

Thank you for the reply! I'm going to share this with the dealer and hopefully that helps them isolate it.

So, got the truck back from the dealer with no resolution.

 

Dealer called and said they couldn't replicate the issue and I know they were driving it because they put 200 miles on it and gave it back to me with an empty tank of gas (while I refilled the loaner because they told me I needed to).  The resolution they stated was that they would call me back and look at it again in a month when they can get the truck in the bodyshop to address a panel alignment issue with the front bumper. 

 

Then it gets ridiculous. Less than 100 yards from the dealership the noise starts and is as loud as it has ever been. I turn right around and go back to the service writer and he rode along and confirmed that the noise was there, wasn't normal and didn't know how the two techs that drove it could have missed it. 

 

Still then, they say I need to take the truck back home and that they would do more research. To top it all off, I get gas at a gas pump with a screen on it after I leave and it plays an ad for "GMC Certified Professional Service" which I thought was more than a bit ironic. 

 

At this point I want to let the dealer have another stab at it as if they truly couldn't replicate the issue for some reason I don't want to hold that against them. I get it, this stuff can be hard to chase down. I just thought that buying a new vehicle meant it would be relatively flawless for at least a little while. At least that is how it worked with my two Toyota 4Runners. 

 

I hope GM sees this and reaches out. I'm a young guy and have a lot of new vehicle purchases left in my lifetime and I'm starting to rethink my purchasing decisions.

Thought I would close this off with a win for a change.

 

Third dealership I take it to looks at the wiring harness above the transmission first like I asked. They find that the transmission vent hose is routed under the wiring harness causing the harness to rub. They corrected the routing and zip tied the harness and the issue was resolved in less that 45 mins. This same feedback was given to the other two dealers based on a post on this forum and they ignored it. 

 

I'll be a customer for as long as I own that truck with the third dealership from this experience alone. I guess the message to others is that don't be surprised if the first one or two dealers you have look at an issue ignore your feedback and keep searching for a place that will.

Very glad you got your issue resolved.  It seems like very few dealers understand how they need to run their operations to earn loyalty.

Same sound my 2020 Silverado makes over certain roads though way less severe than yours! I’m at 9400 miles will have them look during my second oil change soon. 

I'd really encourage asking them about it because it was night and day difference with mine. What was odd is it was completely dependent on road type for me. In Wisconsin, most roads used to be concrete and have blacktop over broken down concrete (at least the ones I drive on) and it squeaks like in the video. Mildly rough blacktop roads in Michigan it was barely noticeable.

I’ve noticed there isn’t any forums labeled to include 2022 Denali Limited truck like the one I just bought.  I guess we don’t exist.

Dude chill, the truck is the same as the previous years. It is not going to warrant it's own tab. It isn't a brand new gen truck.

Have a refreshed Silverado and this is the EXACT same squeak I am getting.  Took it to the dealer and they couldn't find/fix it.  Will use this video/advice when I take it back.  Thanks!

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      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.

      OCI, not when but why?

      By Grumpy Bear · Posted

      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.

      Rattle in the rear!

      By MASONV88888888 · Posted

      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.
