Brake sounds when stopping

[GCG]

Anyone have problems with Brake sounds with new 2019 GMC Sierra 1500 X-31

I am having brake noise when stopping.  When to dealer and they replaces all 4  rotors / discs, due to burn spots on all 4  -  then returned home and still the same problem. 

Went back to dealer and asked why they didn't change all rotors /discs and brake pads and the same time.   They said that the pads looked good.  I have now asked why can't they do a  complete new rotor /disc and pads and all 4 wheels.  Dealer says that they have to contact the GM engineer before anything else is done.  I have been waiting now for over one week for this to happen.  Now I have approx $50K  sitting in drive way, waiting for someone to contact me.    Calling GM support does absolutely nothing, just someone taking down your complains and telling you to wait for a return call.
