Anyone getting a popping noise from their roof?  Every morning when I pull out of my garage and go over a slightly angled transition between my driveway and the street I get a popping from the roof.

I have it almost daily. I’ve narrowed it down to the spoiler on the rear of the cab. Generally speaking, and I can’t back this up with a scientific explanation lol, I think it has to do with expansion

RST here no sunroof, I also get the popping. I figure it’s Houston heat on that plastic spoiler causing expansion / contraction. I get it multiple times daily

My 2019 trail boss LT has the pop and at first I thought it was just rocks coming out of the tire tread hitting the wheel well.  I sat in my truck for approximately 20 minutes yesterday with it idling and I bet it popped in the backseat roof area probably around 10 times.  It seems to be getting worse and I only have 1200 miles.  just ditched a 2015 sierra Denali that was garbage and now this.  Crazy

Yes and warranty is great but the hassle and risk of further problems that will result as they try a ton of fixes isn’t.  Especially when they have no fix and just throw parts at it hoping something works.

I agree it’s an annoyance but that’s all it is. The trucks not a piece of junk because plastic expands or contracts when hot or cold. There really wouldn’t be a Firm fix unless they did a drastic redesign, which will not happen until they completely redo the truck. If putting some butyl in between the roof and spoiler gets rid of the problem, what more do you want?

I hear a fairly loud popping from the roof on my 2019 Silverado Custom. It's not just an occasional pop. It's more like canvas flapping in the wind. It's worst at around 50 mph. A few minutes ago I stood on a ladder to get a good look and found out that I can reproduce the noise easily by pushing down and releasing the sheet metal right over where either the driver or passenger head would be. Both sides pop. It only takes finger pressure to do this. It has nothing to do (in my case) with the rear plastic spoiler. It's just thin, flimsy, unsupported sheet metal flapping in the wind going down the road. I have less than 3K miles on this truck.

 

While it is very annoying to me I'm more concerned about the long term effects of all this flexing on the paint and metal. Some time in the future I believe I can expect the paint to pop from all the flexing.

 

I'll be taking the truck in for service later this week anyway so I'll talk with the dealer about what, if any, options there may be to mitigate this issue.

 

If I don't get some help there I'm going to look around for something to mount at the leading edge of the roof to break up the air flow and see if that helps.

 

EDIT: No help at all from the dealer. No service bulletin = no help. Since this is not a safety issue I really doubt GM / Chevrolet will address this unless they get a lot of negative publicity.

 

As far as a self fix goes no luck so far. All the stick on trim I've found so far is too flexible. I looked into sun roof deflectors to break up the air flow but all the ones I've found are stick on and prone to flying off. I don't want to risk having one of those things fly off and hit someone's windshield. Still thinking about a solution.

Hello, first post here since buying a 2019 GMC Sierra 1500 SLT. I too have had this popping issue since day one. Has anyone found a resolution to this yet? It is very annoying to say the least.

I have a 2019 Z71 4x4 RST quad cab. Of course in my short test drive the truck was so smooth no noise. I drove it about 100 miles and the roof started popping. I’m not a happy customer. I paid extra to have the material inside my wheel wells to make it quieter lol! What a joke. 50,000+ on my truck and it sounds like Little Rock’s or acorns are dropping on my roof all day! It even does if not moving! I can be siting in my truck in my drive way but driving it fir hours and it pops. I owned a 2015 GMC Sierra and it was a solid truck. I hope they figure this out! Plus my drive auto window is messing up

My 2019 Silverado does the same popping sound in the rear cab roof area.  Especially when the sun hits the cab as I’m driving and hit small bumps or driveway ramps.  I think it’s coming from the plastic air spoiler (for the lack of a better term) mounted on the top rear of the cab.  It’s annoying especially since I don’t even have 500 miles on it yet.  I’ll wait it out until the first service visit to have it checked.  I hope it goes away before then.

With the first 700 miles, I've noticed it 5 minutes after driving out of a closed parking structure to a warm to hot en environment. Now that I'm at about 1100 miles, it probably does it once a week compared to happening a several times a day.

My "pop" has settled down to a "tick", maybe once per trip. And no sense bringing to a dealer because he can't change the laws of physics regarding different rates of expansion for different materials. And if he does by torquing the crap out of the retainers......no more pop......just one big snap as the plastic cracks.   Actually the redesigned spoiler with LED lighting tilting the light below the sports bar was a great idea as far as I'm concerned more than justifies an occasional tick or pop.

 

Besides I was getting in my Traverse the other day and heard the plastic spoiler on the rear of the roof pop in the Sun. No pop posts on the Traverse website,  either don't hear it from inside the cab or none of the owners are noticing it.

Well, in my case it's not a tick or occasional pop but rather a full on metal flapping in the wind sound and at certain speeds that is constant. Maybe there are more than one problem associated with these beer can roofs.

Wow funny you said that as I was in my wife's Traverse Saturday waiting for her to come out and I heard the same thing.

Finally figured out exactly what my noise problem was. It was NOT the roof flexing like I thought it was. Nor was it any of things others were experiencing. It wasn't even a GM/Chevy problem after all.

 

Back in late June I had a camper topper installed. Mid-July we went on a beach trip. The noise started on that trip and gradually got worse over the next few months until it was pretty much constant at certain speeds. The other day I was looking in the gap between the topper and the truck cab and noticed that the front rubber seal between the bed and top was coming out and actually touching the back of the cab for over a foot in width. I got my wife to sit in the back seat and we did a road test with her listening carefully for where the noise was coming from. She said it was right below the window. From the driver's seat it still sounded right over  my head. And LOUD. Go figure.

 

In any case, the camper topper has a removable window there so I removed it and cut away all the protruding rubber seal material. Reinstalled the window and road tested again. NO noise!

 

Just need to get the seal replaced now to prevent any leaks. Sure is nice to have a quiet ride again.

So I took my brand new 2020 to the car was for the first time and it has blowers on the crane that move the length of the truck when they hit the roof it popped very loudly. When I got home stood on the running boards and you can move the roof very easily almost like plastic. I’m guessing it very thin sheet metal. I guess a lot has changed since 2005. Come on GM ?

      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.
