I have a 2019 silverado new body style, i recently developed a rattle in the dash around the steering column, i took it to two dealers and both couldnt find anything. Now the warranty is up and im stuck with a rattle. I am a diesel tech so i tore apart the dash peice by peice and kept driving it around and the rattles continues. So I tightened every bolt i could see and none were loose. I even used a stethoscope going down the road and found that the rattle sounds like its coming straight from the steering column near the bottom. Maybe a bad column im not sure i attached a video of the sound, and it only happens around 45-55mph
