One problem related to brake disc pads has been reported for the 2017 GMC Sierra. The most recently reported issues are listed below.
I has some issues with my brakes when stopping at a red light. I stepped on the brakes and kept rolling forward and almost hit the truck in front of me. I thought it could be my pads worn down so I drove cautiously for a few days. I got a call a few days later from the dealership where I brought the truck from saying my on star notified them of a recall on my truck pertaining to the brakes. I thought good this could fix the problem. I took it by the dealer and they said it was a software update, and they did the update. I also asked them to take a look at the break pads so I could rule it out or do something about it. They said I have 60% of my brake pads still left. The next day I was going to work and I got to the parking garage where I work and noticed it was doing it again. I pressed down on the brakes to back up and I kept rolling forward and had to press down hard and to the floor so I could stop. So far there was not a crash but I feel its only a matter of time. This is a major safety issue for me and my family and feel there should be some sort of recall to fix this.
