I am also having this same problem on my 2015 SIERRA. Gmc customer care is useless. They have ghosted me on two seperate occasions now I will not even bother contacting them on this issue. The volume goes all the way up on its own. I've tried everything. Truck was bought new by me, it has 120k miles now. I've replaced the transmission once at my cost because gm said it was fine...... had lifters replaced for the afm after leaving me stranded and losing 4 cylinders, a/c condenser replaced (bad welds), driver seat covers replaced twice for tearing (I'm only 200lbs), had to the dealer twice now for being stuck in 4 wheel drive to have computer reflashed, the rear right leaf spring came apart about 20k miles, the transfer case has so much play in it, clunks going in and out of gear. When doing my very first brake job at only 20k miles it was realized the calipers were installed in factory with absolutely NO GREASE on the caliper pins,  causing the premature wear. My mother has a Denali with the same radio as my sierra and it has already been replaced by dealer for around $2k. Been a gm guy my whole life and been happy with that decision but these new trucks are garbage. And gm customer care doest care at all...time to make a change. I'll bet the steering wheel controls are the issue here, probably in the steering column. Yay

Not sure if anyone has the same problem as mine, but I fixed mine on 2018 gmc sierra

 

My volume could go up to 30 ish in volume, when I put it louder it would go down in volume. Has done this to me twice in the last few years.
 

The way I’ve solved this problem is connect my Iphone to the stereo, open Apple car play, goto maps, pick a destination, when she talks turn up the volume, then it fixes your music volume. Not sure why they intertwine with each other sometimes, when they are supposed to be separate.

 

hope this helps someone.

2016 GMC Denali dualie-same problem with radio.  All of a sudden volume goes up & then down.   Red line shows how far volume is up & then a smaller red line continues from that red line.  Just turned truck off & turned auto volume off.  Volume works now.  So we will see as I have tried everything else!  Just found this website so thanks for advice!

First time this has happened to me.  Had the truck for a year and a half.  Was in it all morning, everything normal.  Got back in it after lunch, radio full volume with no control, no response on the screen.  Turn the knob really fast would get it down, but would return to full volume on its on. Shut the truck off several times, no change. I recently replaced the starter, matter of fact, the day before this incident. The radio has done some other funkie things on its own, but not this.  I thought the speakers were gonna blow.  Any suggestions??

I know this is an old post but I just had the same problem where my volume would immediately start going down to 0 every time I tried to turn it up. After frustratingly trying multiple things, here is what worked: once it hit 0, I spun the knob like I was turning it down, and then the next time I tried to turn it up, it worked and has been working since.

    • www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.
    • Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.         
    • I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far. 
    • I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install. 
    • Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
