NHTSA Complaint #11680087 — 2024 GMC SIERRA 3500

I just bought my truck a 2024 GMC 3500 and in a few weeks after purchase. I took my truck in for a break vibration. I took the truck back in to find it had bluing on the rotors and the break pads have holes in them. I was told this came from over heating. They said it was missed on the pre sale inspection they did. I looked up info to see if this was a common problem and found the in 2022 GM changed the material to help with noise problems and this material had been know of premature break problems. The dealership denied doing the work under warranty. I called GM customer service and they told me to work with the dealership, the dealership called the district manager and all parties have decided to ignore the issue. I also have 2 of these truck driven by 2 different people with the same problem at the same millage. I will make a 2nd report for the 2nd truck.
