Took mine (2019 RST) to the dealer today. Was doing very same thing and was constant. The service manager had fixed one truck before so they told me what to do and it works. 
Lower both headrest down low as they will go. That’s it and it will go away. The posts rattle the inserts if they are up. 

Mine were as low as they could go & rattled at every position from the time I took delivery until the tech spread the bars apart. Haven’t had an issue with them since. They shouldn’t  rattle regardless of the position.

I agree fully ! They cost way to much to have stuff like that going on. I’m glad to hear that yours got fixed as well.

Glad I found this thread! This has been driving me crazy! I took it into the dealer, and he said others had complained as well, so he submitted a ticket to GMC. Hopefully if enough complain they'll come out with a fix. In the meantime I'll try spreading the bars apart a bit.

Yes.  I had the same issue.  Removed the headrest and it went away.  I will try spreading them apart more.  Should have been caught in squeak and rattle test at the plant.

My 3 day old loaner 2020 Silverado is doing this. Makes me crazy

Same problem here 2019 high country.  Thought about spreading the posts a little but would like them fixed properly if GM has a correct fix ?  I guess the dealer fix would be ordering new grommets or headrests ?  So nice we have this forum to help figure this stuff out ! Thanks everyone !

Mine rattles noticeably at low speeds on rough pavement. Going to check this out tomorrow I had hit all the parts back there with my hand and could not duplicate the rattle. Thought it was the headrest at the time. Dang GM 70k rattle TRAPS. Great QC GM Hahahaha

Could be the covers for the seatbelts up in the C-pillars. Mine were loose as well as the driver and passengers ones

Yes, I have the same issue in my 2020 GMC 2500 HD AT4.  Like you, it took me a while to figure out what it was.  I removed the headrests and the rattle disappeared.  With the headrest off, you can wiggle the metal bars and hear/feel the top of those bars hitting the inside of the headrest.  If they didn't fold down and were stationary, I suspect they wouldn't rattle.  I'm trying to figure out what I can do to stop this.  May try pulling the bars apart as suggested I this string.

Awesome.   So glad I found this thread. That is the only issue I've had with my truck in almost 5 months. It started right after I put in the Kicker subwoofer so I thought it was something sinister going on.   I just left them out,  I need to take it in for the brake recall and they can fix it then.

Same issue with mine. I tipped them down and wrapped the seat belt strap around to keep pressure. Tried to pull them out but was afraid i would brake something. May try that again.

Theres a little button on the grommet that you gotta squeeze in, then pull up on the headrest

    • Oil pump noise was discussed before.  I will try to remember to record a remote start later this morning. 
    • There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
    • On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.
    • 2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!
    • 2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.
