I’m debating what to do, I have some 3m Tessa  tape I use for car audio installs that I think would work good. I’ll have to spend some time taking a better look to make sure whatever I do, do to it, d

But in case anyone’s reads this thread looking for an answer, here are a few issues I found on the forum that cause a noise in the rear 1.) the headrests, pull them out and spread the prongs out

My little velcro trick seemed to work. I cut a 2" piece of velcro and used the "soft" side of it. Stuck it on the window and no more noise!

I tested opening and closing the window while watching the track and it doesn't interfere. I went with 2", but you could probably go for the length of the track, but if the window is open, you probably wont hear anything anyway.

Thank you!! My truck is dead quiet except for what I believe to be this rattle. Will try your fix, hoping it helps.

I moved the back window just enough to put some tension on the chain and it definitely seemed to help. I need to drive some more but it looks like the chain might be part of the issue.

What do you mean you moved the window? Like, you cracked it open a little bit?

You can press the button for a split second and it moves just slightly, maybe a 1/4". Seems like its still sealed since i dont get any wind noise but i have not tried with water. Mine stays in the garage so ill look when i drive in the rain or wash it.

Same rattle here.  Had a similar rattle in the past on a 2013 Silverado crew.  On that truck it was the latches that secured the back seat to the rear wall of the cab.  Got in the back of mine yesterday and pulled the head rests.  Sprung them ever so slightly at the bottom and the noise seems to be gone.  Mine seemed to be coming from the driver's side rear.  Made no difference if I had a rear passenger or not.  Fingers crossed, and if the noise returns, I'll keep on searching.

A drive earlier today seems to confirm that nichos’ solution also fixed mine. I used a 4” strip of Velcro in the same place as he did, and the rattle over rough roads seems to be gone.

Great job nichos!

I tried everything in here, was at wits ends then thought maybe, just maybe its coming from the outside. It seems to do it when the truck was "flexing"..sure enough, pushed on the rear spoiler in the back driver side and that "squeak" was making it through the cab causing the sound...no trying to figure out how to fix it.

I have less than 2,000 miles on my pickup and took it in and they said it's the leaf spring. They retort the leaf spring and put additional grease on it less than 250 miles later the rattle is back. They said to bring it in and they will add more lubricant which I replied I did not pay $40,000 to come in ever 250 miles for y'all to add more lubricant to it fix the damn thing

I have a rattle in the rear of mine also but I think its coming from the headliner. If I get back there and push up on it you can hear it smack the roof. Someone else on here said there are dense hard blocks of Styrofoam up there can hit the roof when you hit bumps etc. Gonna have them look at that when it goes in.

I just bought 2022 1500 Denali today and I can’t hear anything while on the interstate but as soon as I slow down and go over any kind of bump I have a very loud rattle coming from the passenger side only has 125 miles on it. What do you guys think it is? I’m ocd and is driving me crazy. Help

Headrest’s. Take them out and pull apart the rods holding them in

 

Also check your tire jack being properly secured

 

3rd check the bolts holding in the seats. They can be loose. 
 

4th is spoiler. 
 

5th is window itself

 

i had dealer end up fixing all of these like 1st month of ownership. Really quiet now. 
 

take care.

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.

      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.
