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. 

Posted

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 hope to high heaven this is wrong. My Chevy farm trucks frame is lasting way longer than a newer Nissan Titan XD I got for a steal, and it only pulls trailers. A decade younger and it's frame is already way rustier than the waxed Chevy I drive across longs and ditches. Also, hasn't Ford been having tones of troubles with rusted frames? 
    • Batteries don’t always show signs of a few years ago my vehicle started fine in the morning and took me to work. After work the battery was completely dead and I needed a jump. No, I didn’t leave anything on and the battery was only a couple months old. It was replaced under warranty. 
    • AFM is confirmed in the Corvette engine, so I'm assuming the higher volume trucks will get it as well
    • If his battery was that bad I would think it would have been showing signs before this that were ignored. Stinks that it happened the way it did in rush hour traffic, but this seems like a pretty fringe scenario. I don't mind it that bad and never turn it off. The only slight annoyance for me is the slight delay between brake to gas, but I have gotten used to it and figure if it can save a little gas why not.
    • That is a good correction. I think “severity” was probably the wrong word for what I meant. What I really mean is closer to event priority, relevance, and actionability — not “this code is severe” or “replace this part.” I agree that a truck can have a lot of trivial or historical communication codes, and if the product starts pushing alerts for every stored or low-value event, people will ignore it very quickly. So the alert logic would need to be filtered. For example, I would not want a random old communication code to generate a push notification by itself. A useful alert would probably need to be based on things like: - new vs historical - active vs stored - repeated vs one-time - duration of the event - whether it happened near the driver-marked symptom - whether it happened together with voltage drop, reset, bus-off, misfire, oil-pressure change, etc. - whether the same pattern repeats under similar conditions So instead of saying “severity,” maybe the product should organize events by affected system and priority. For example: Misfire event: Show misfire counts / roughness first, then fuel trims, RPM/load, DFM/AFM state if available, coolant/oil temp, voltage, and related DTCs. Oil-pressure event: Show oil pressure first, but only in context — RPM, load, oil temperature, coolant temperature, DFM/AFM state if available, voltage, and baseline comparison. Communication event: Show which module/network/message dropped, whether voltage dropped, whether the recorder reset, whether it was active or historical, and whether it repeated. Voltage/reset event: Show battery voltage, crank/wake/sleep state, module reset, communication dropouts, and what came back online first. That also solves the display-order problem you mentioned. The main report should not always show the same fixed list first. It should show the system that appears abnormal first, and then the supporting values for that system. I also agree that the truck already has an oil pressure gauge and MIL. The point would not be to duplicate those. The value would be in showing what else was happening before and after the warning or symptom. For example, if the MIL comes on for a misfire, the truck already told the driver there is a problem. The useful part would be: - which cylinder or bank looked abnormal first - whether it happened after an AFM/DFM transition - whether fuel trims were already moving - whether oil pressure or voltage changed at the same time - whether the same pattern happened previously without a MIL On the OBD port point, I think you may be right for a consumer-facing version. OBD is much easier for the average owner: - easier install - easier removal - inside the cabin - easier phone connection - easier data download - easier to include a pass-through port for another scanner OBD is also the right place for DTCs, freeze frame, VIN, calibration information, Mode 6, and normal scan-tool parameters. The reason I was looking at ECM-side recording is that some events may be gone by the time someone plugs in a scanner, and some powertrain-side network evidence may not be available the same way through the DLC. But I agree that if an OBD-based version can capture enough useful evidence for most owners, that is probably the cleaner consumer product. Maybe the split is: - OBD/DLC version for most consumers - ECM-side version only if it proves it adds evidence that the OBD version cannot get - shop/pro version if deeper powertrain-side event evidence is actually useful So I would not want to force the inline approach if the OBD workflow solves most of the real-world problem. Your last point is probably the key product requirement: the report should be specific to the system showing the abnormality. Not “here are 50 parameters.” More like: “Misfire-related event detected. Here are the misfire/fuel/DFM/context values.” or “Oil-pressure-related event detected. Here is oil pressure compared with RPM/load/temp/baseline.” or “Communication event detected. Here is what dropped, when, and whether voltage/reset happened first.” That is a much better way to think about the report.
