My first post as a new member. My new 2015 Silverado 1500 has the same popping noise. It appears to be due to a temperature contrast when the AC is turned on and the hot plastic bezels surrounding the audio controls and the AC vents expand or contract. It seems to disappear after a few minutes or become more infrequent. Since I'm in the Texas heat I'm looking forward to the late Fall and Winter to see if still occurs. This hasn't happened on any vehicle I've had since the mid-1980s. I would have thought this would have been engineered out by this time. By the way, thanks for all the tips and knowledge. It has kept me from a needless trip to the dealer already.

My wife's 2016 Tahoe does the same thing...after a short while it does finally stop. The cooling of the hot plastic bezel makes sense, so thanks for the explanation.

I've only had mine for about a month and have been worrying about that sound. The expansion/contraction makes sense. Glad it's nothing major.

Hmmmm. Mine only does it when there's a plastic water bottle on the console.

After having my 2015 Silverado 1500 for a full year I find the popping noise from around the radio occurs no matter what the season is. Between that and the hard to turn ignition key and the seat movement around a corner I find the vehicle lacking in quality.

Frank, I took my 2015 Sierra in to the GM dealership for the driver seat shifting while turning 4 different times before they fixed it. They found a TSB and replaced the whole frame under the seat to finally fix it. Idk what the TSB# is by memory, but I can find it if you need it.

I have a 2018 Silverado with 14k miles, it's been doing the popping sound since day 1.  I live in Southern California and spend most of my lunch time in the truck. After a few hours of baking in the so cal heat the plastic in the dash expands and when I roll down my windows the dash starts to pop. Yup sounds like rocks hitting your windshield. Obviously GM hasn't fixed this issue, this thread is dated back in August 2014, my truck was bought in August 2018 and it is October 2019 now.

      Tire psi

      By Chuck FB · Posted

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      Tire psi

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.
