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?

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      Parking Brake - Automatic Engagement Questions

      By SoCal Angler · Posted

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!

      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.
