BRAKES WENT BAD @ 9800 MILES AND ARE GOING BAD , again @20k miles

[lineman1234]

Im only at 19,000ish miles, and only towed the 10,000lb 5ver about 400 miles so far. But,,, the dash sais brakes at 94% front and 97% rear.  Everything looked great when i rotated my tires a couple weeks ago.

After opening a case with gm for warranty repair which they denied….pages

Like the OP I have had several 2500HD over the last 20 years... my 2023 with 6.6 gas is eating brakes and has the worst warped rotors I've felt in a long time.  While at the dealer under warranty another cuatomer said he had the same issue with his 2500hd.  Mine sees no offroad or anything.  Michellin highway tires... no heavy towing.  I'm beyond disapointed.

Yes, my 2024 GMC 2500 started going bad about 18,000 miles.  Majority hwy miles.  Pulsating, steering shaking.  Terrible.  I had truck at dealer and only a 12,000 mile warranty...well of course if you use crap parts they don't want to warranty.  They said the brakes are safe and I should just deal with it until I'm ready to buy new ones.  Ha. Been buying GM since 1990 and the builds keep getting cheaper.  Pretty sad, jumped up to Denali this time and it's the worst truck I've had yet.  Man oh man not happy.

new to the forum and already I'm asking for input .

let me start by saying I lov my GMC  2500 HD this is my  fifth one since 2002, I

always buy the 2500 HD SLT 4x4 4 door, all gas except my 06 was a duramax, 

as for the brakes my experience has been I get 80 to 90 and 100k on the duramax  before ever needing brakes I retired last year and bought my last truck I hope ..

The brakes on MY 2023 2500 HD SLT  Sierra At4  went completely south at 9800 miles all highway between northern California and Washington state. AND I MEAN THEY DIDNT JUST START PULSATING IT went from fine to the worst warped rotors pulsating bad .the  dealer took care of all of it with front and rear new rotors new pads said GM knew about the issue they had mentioned dust getting behind them I called BS on that , I've done  to many brake job to know that they're always full of dust unless dirt was getting in and around the caliper piston causing them to stick they never elaborated on the reasons ,,anyway whatever the reason GM  replaced all the parts with supposedly upgraded rotor material and better pads ,,,,, I just turned 20,000 miles and the brakes are starting to do exactly the same thing not as bad but I can tell the rotors are starting to get warped  I have an appointment at the dealer tomorrow , my question for all of you have any of you had the same problem, I have searched the Internet cannot find anything about GM replacing rotors and pads due to bad material I see stuff about brake boosters pressure switches ABS systems on the up until 2018 I see nothing about 2023 with bad rotors because it 20,000 I'm sure there's gonna be pushback from GM brakes aren't warranty to begin with but they had a known problem they fixed it once and I will never let them off the hook looking for fuel  my argument .

I wonder how many new truck owners follow the break-in procedure concerning accelerating and stopping. I did as best as I could when I got my truck in Jan 2024. Currently at 12k miles. We’ll see how it goes in time. It’s my only vehicle and doesn’t sit around much. I’m retired and didn’t have to drive in rush hour traffic during break-in and didn’t start towing until late Spring.

GM bought my truck back full price plus tax and license extra year of reg in California as you  know that's 1000 bucks a year plus the couple hundred dollars I spent on oil changes plus a $500 coupon towards a new truck I took them up on your offer I have since ordered a 2025AT4X , we'll see how this one does for you guys that don't push when your brakes go bad under 12,000 miles in California it's an easy lemon law GM knows it I didn't do anything I was in the middle of arguing with them to get it fixed all I wanted was them to fix the brakes a third time they did it twice they refused and in the middle of that argument out of nowhere they offered to buy the truck back how can you refuse I drove 20,000 miles on it for two years and it didn't cost me anything but gas and three month headache but what do you want perfection in this day and age  not gonna happen 

[RGA]

Good luck are you guys I know other states aren't as easy as California interesting note during that three month discussion with them and their agent they never admitted that this was a lemon they never admitted that there was anything wrong with the brakes they never admitted anything they offered to buy the truck back  as a 25 year GM customer .

And they wanted to see me satisfied that was pure BS they knew they had a  break problem and it's not nothing to do with the quality of the rotors or the pads this is the electronics stability control system, not ABS not the steering stabilizer not sway control but.. .ESC 

During my personal inspection because I took those brakes apart myself checked the rotors for run out yes I had all eight lug nuts torque to spec during the check of those but I went one step further I put my dial indicator on the rear axle HUB FLANGE if you guys know the three-quarter ton is a full floating axle it's identical to a front hub it is supported by two wheel bearings what I found is that axle Flange .008 lateral run out it should be less.0005 to be within limits.

So you could put a brand new rotor on that rear hubs and put a dial indicator on it and you would already have .016 thousands runout which wOULD  just compound daily as you used your brakes... I know my two statements contradict each other is that the ESC or is it the poorly machine axle flange I believe it's both.. our rotors are an inch thick and all specs say a rotor that thick can have.002 run out and they will last forever but you put that rotor on a bad axle flange and then throw an ESC system that's out of whack those rear brakes are like a parachute that's how the ESC works it wants to try and straighten you out at all cost by applying just the rear brakes Left and right whatever the computer thinks it needs to do to keep you going straight!

I do live at the top of a very windy mountain it's 4 miles long and I don't drive it slow. my four or five GMC Sierra trucks were not equipped with ESC and I never had an issue so I don't know what the heck I know is I'm pretty happy this week I know I got a brand new truck and didn't cost me a freaking dime.

Hub end play is 0.025 – 0.250 mm (0.0009 – 0.009 in)  

 

.008 is on the high end of in spec, but is in spec.  

 

Rotors assembled lateral runout is 0.05 mm (0.002 in).  Assembled is rotor on the truck, conical washers installed on the studs that will seat the lug nuts, and then torqued to wheel fastener spec.  

[RGA]

I'm not referring to end play on the hub or the wheel bearings that support the rear hub talking about lateral run out of the hub flange

Materials used now days are not up to specs and durabilty.  If you feel you haven't gotten the right answer, let me know as I have the solution for you.  Look up Pureforge.com. They are remarkable and will last the lifetime of your vehicle and you won't have to worry about issues.

Well guys GM actually came through after the repurchase of my 2023 AT4 that was my retirement truck and it was pretty sweet but I wasn't gonna get stuck with a truck that needed breaks every 12 to 20 kmiles , so a week ago Dublin Buick GMC called to tell me that my 2025 AT4X 2500 HD  that was a special order due to the 6.6 gas motor on 11/6 was ready and  all detailed out and ready to pick up but it was too late in the day for me to drive 100 miles round trip .

so I decided to wash off my Tonneu top that I bought for the 2023   so while I was washing that off soap and water and some stuff to  make it shine like new because hell it was new when I took it off .

but DAM IF I  DIDNT SLIP and fall on my concrete driveway that  has a little slope to it not much but wet and soapy that's all it took to slip and fall landed just right and broke my left femur the fracture went all the way through pretty low rotated slid up got  muscle damage anyway that's another story in the hospital for a week I cannot even get in this truck it's too tall for a gimp andits too painful but give me a couple weeks, and it was my left leg so all I need is my right go pedal foot I love in this truck man it's looking pretty good inside is loaded got the massaging seats got some other stuff that I don't believe was part of the AT4X package,

The good part of this  my daughter flew in from Scotland where she lives to help my wife take care of me for a week so that was a bonus out of all of this I only get to see her once a year so now it's twice a year back to the truck it's BITCHEN hopefully they fixed the brake issues they claim to have. I would like to hear some other GM REpurchase stories or am I the only one with a truck story well hopefully the picture loads sorry for the long post guys but that's what oxycodone does to me and the other reason I can't drive the truck happy happy happy as the other part the oxy does to an old 66 year-old man next week on Tuesday

Well guys here's the end of my story first picture is the broken rotated femur just below the hip joint and the second picture is the repair check out that hardware and you got a zoom in on it all the way and I guarantee that no one else has hardware like that in their femur, don't tell my wife but while she was out getting me more meds and food and feed me I took my walker and my daughter and she was able to help me climb up into the driver seat sure feels taller than the planeAT4  man is it comfortable the seats are so nice the bigger dashboard compared to the 23 just the layout in general got the safe mounted inside the console the storage box with you know better than nothing plastic gun rack under the backseat heads up display was something I wasn't familiar with at first I could barely see it and I was puzzled  but turns out there is  a button to raise and lower the heads up display wow pretty nice I'll get it figured out got the OnStar and the my GM app connected paired my phone and drove it for about a 10 mile test drive no worries I hadn't taking any oxy all day so it's all good.

 It sure feels like it rolls better on the 305s then the 285 that my other truck came with so far I have no complaints how could I it's only just sitting in my driveway got my AirTag buried in it so that nobody will ever find it .
Well that is all oxy talking right there Honestly can't wait till I don't need that ****** Doctor says probably another week For the pain to reside

Did you find a solution for your Brakes?  

[XY74]

Yes, it appears he traded it in.

 

How's the shoulder doing now?
