Pads from manufacturing who make the brake pads for Gm  we’re replaced because of squealing at a crawl 

they replaced the pads and it started again after a week  

anyone else have this problem 

call Gm and waiting for reply 

dealer said they wouldn’t do anything about it they replaced like Gm had instructed

@maximumspeed, I have the same problem (still). I found another post mentioning this issue that referenced a bulletin # (20-NA-020 - https://static.nhtsa.gov/odi/tsbs/2020/MC-10172288-9999.pdf). My dealership replaced all of my pads and the noise is still there. I asked my service department about it again and they told me that the "mixture used in the brake pads was changed with 2020's and they're still working on figuring out the noise issue". They also told me they'd replace the brakes again whenever the mixture gets figured out. I think it probably won't ever be figured out and I'll just wind up replacing the pads / rotors setup. Side note - I live off of gravel so not sure if that has anything to do with it but my last Chevrolet truck didn't make noise like this while I drove it on gravel.

I broke 30k and since I bought it new they have squealed.  Conway, AR dealership stated several times that they are working as designed no issues with them squealing.  Got to love it.  Showed them instructions from GM on what to do.  They have refused and stated it is working as designed.  Good luck on if they will address it.  Probably going to upgrade to PowerStops as I have NEVER had them squeal.

Dad had the same issue, dealer replaced the pads twice, the squeal always came back at low speeds.  Finally got frustrated, and even though still under warranty installed the wagner posi quiet (might have been centric thermo quiet pads)  Problem solved,  I know it sucks, but the noise was driving dad crazy.

Dealership just replaced my fronts, they said the back pads were still backordered.  I did not notice any squealing driving home.  I do think the majority of the squealing was coming from my back brakes though.  Guess we will see.

Im having this problem again too.  Is the issue the GM mechanics are not orienting the brake pads correctly and just slapping them on like any other? If I remember the TSB didnt it say the inner/outer facing brake pads on the caliper were slightly different?

Just so everyone knows I had a call from Gm about my brakes and they tell me that they won’t pay for another set of brakes as they have been replaced once then she tells me that they recommend new brakes every 12000 km lol my reply was WHAT

seriously who is this person. I will be calling tomorrow because the person that called me I’m sure has no ideal what the hell she’s talking about 

more to come stand by 😎

Ah yes, the awful squeal noise on my 2020 GMC Sierra Denali HD (2500) is familiar. I've had my pads replaced once and the squeal came back quickly. I am looking for an aftermarket option and prefer EBC brake pads and rotors, but they don't have any pads for the 2020+ HD trucks. I think that GM screwed this one up BIG TIME with the consumers, but what do they care, because vehicle demands are way to high and customer service has suffered. I was in shock when the dealership pad slapped my new truck with the service bulletin. At least the rotors should have been turned.

Drive through is the worst expensive truck with this god  awful squeal I am going to look into the new pads 

thanks 

I truly respect the decision of those that continue to "dine out" fully accepting of the challenge "what'd they put in my food today".  😉

Good for you they tell me that they won’t replace twice they replaced my pads and it started up again in a couple weeks 

Why would you expect the pads to change the squeal? The compound of the pads they use is what causes it, new pads will still squeal if they don't change the material and at this point it's a safe bet they have not and will not change it. Just need to try some aftermarket pads.

      Some Assembly is Required

      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.

      Software Update

      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.
