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?

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
