    2019 GMC Sierra AT4
  1. I have this same squeaking with my AT4. 2,000 miles on it currently, but it has been doing it since around 300 miles. I agree that the squeak happens when the frame moves and appears to be coming from behind the climate controls, which is adjacent to the push button start. After one unsuccessful attempt to locate it by the dealer, I removed the majority of the console and center stack. Still could not pinpoint exactly where it was with the duct work in the way, but it was significantly louder. I am also guessing it at or close to the firewall. It is back at the dealer for round 2.
