2020 GMC AT4 Garbage Brakes!

[RossEGCA]

I have a 2020 AT4HD and have been dealing with this brake issue since I first bought it.  I had it to the dealer 10 times, had the pads and rotors replaced several times and the problem never went away.  I kept telling them it was an incompatibility issue between the pads and rotors and they could replace them 100 times and it won't fix it.  GM Corporate got involved and eventually they told me they were not going to do anything else about it. I could not find aftermarket pads at the time, but found rotors.  I bout cross drilled slotted rotors and that helped alot, I was redently at the dealership for a part and the service guy told me there was a new service bulletin and they have changed the pad compound and will replace them again. I have an appointment on Tuesday of next week so we will see what happens.

Do you happen to know the new service bulletin info for this? Just had mine in Friday and they gave me the same info that is all over this post blaming the lining and that even if they replace the pad people say they still hear the noise. I'm trying to figure out if I want to put aftermarket pads etc on the truck, but of course the dealer is saying i wont get the life out of aftermarket parts.
