My “dump truck” is worse now than when they did the TSB brake pad replacement! I took it back to them and they told me, there is no fix apparently and I get to live with it until GM comes up with something else to try. I am over 12k now, none of it was hauling a trailer but I am about to put a 36’ toy hauler on it so here we go...Thanks GM.

Found it, a little google always helps. Thanks all. When I called to ask them if it was covered under warranty she said bring it in and lets see. I mentioned I found the TSB on it, so it should be cov

there is a TSB for this issue. Apparently the early build trucks have an improper spec'd pad. they replace pads at all 4 wheels

No. It’s intermittent also. It happens the most when coming to a stop at low speeds <10mph and it always happens in a drive thru.

Mine originally started screeching around 10K. Dealer in Missouri replaced brakes in October of 2020. They were quiet for about 5K miles. Now in Florida and were really noisy for 1st 20 minutes after sitting for 3 or 4 hours. Took to dealer here and found out the Missouri dealer had only replaced the fronts. Had to leave truck overnight so they could really hear the problem. They ended up replacing all 4 under warranty along with a loaner vehicle. It's been quiet now for 3 weeks. If your dealer won't help, find another dealer. The dealer here told me they were doing 2 or 3 per week so it's a very widespread problem. Mine also had that big dump truck sound. Good luck!

Well, this issue continues...  Took my 2020 Denali in for second oil change, 11400 miles, brakes 97% front, 98% back. Service advisor moved my truck and then came and found me in the waiting room and said "what is wrong with your brakes?"  Perfect! He found the TSB and ordered the brakes. My truck was built Jan 20. Will see what happens.

just turned 7K. noticed my brakes starting to squeak at slow speeds. 

I have heard the new pads on the TSB have been revised again... any truth to this?

Got my new front and rear pads installed and now all is quiet again. They tried to clean them twice but didn’t last. Replace is only fix.

I've been dealing with this issue for the last 12 months.  I bought my 2020 AT4 HD in February 2020 and brakes started to squeal in the first few months.  Got the run around from dealer for a while and found the TSB so they put new pads on.  Started to squeal again and they said can't do anything more.  Called GM Corp and after a long time of being ignored they finally kept my truck for 10 days and put new pads and rotors on.  Now its squealing again and I'm back dealing with corporate again.  It's been in the shop 10 times, mostly for brake related squealing.  I'm not sure what more they will do, but I'll see.  I'm temped to just buy after market pads and do it my self since the GM components don't seem to be working.

Any updates? My Chevrolet dealer said your truck is a GMC maybe their dealer has a fix, take it there! We are done trying. Can you believe that nonsense? I called GM corporate. I’m ticked.

Bump for updates. GM made the dealer take another look at my truck, still squealing badly and is an embarrassment to drive. The dealer got back to me today and said sorry, there is no fix and we made no changes. Maybe I can get GM to buy a used truck.

KC Desert, did you try a GMC Dealer? Mine are still quiet after the change 10K miles ago. They changed all four on mine the last time. Hope I didn't just jinx it.

I have been to a GMC dealer before and they were the ones who replaced the brakes initially, at 4K miles or so.

Mine started mild squeal about a month ago around 10k MI.  Going in for the 2nd oil change next week.   We'll see what they tell me, but now I know it's not just mine.   Tow a 25ft travel trailer every once in a while.   The dashboard still shows more than 95% for both front and rear axle.

I escalated this issue to GM and they have done nothing in two months time saying this is something they are investigating. Ok, I am not a brake designer but…I bet Midas can figure this out in about an hour. GM? Hello GM? My brakes have been replaced already and they went from bad to even worse. How difficult is it to diagnose why brakes squeal and make an $80k truck sound like a dump truck?

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed. Why not updates as well, especially since some of those can be safety related also?

      Tire psi

      By jgaudet99 · Posted

      That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?

      Would this CV Shaft be bad?

      By newdude · Posted

      That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?

      Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
