NHTSA Complaint #11713584 — 2024 GMC SIERRA 1500

While driving the vehicle I hit a bump on the road and all 4 windows in the vehicle went down. I did not push any buttons. I tried to close the windows and they would not close. Nothing happened when I attempted to close them. It was 10 degrees out I pulled over, and tried again with out success. I shut the car off, opened the door and closed it and restarted the car after a few minutes. I was able to close 3 of the 4 windows. I started driving and eventually I was able to close the last window. ON my drive I late hit another bump and again all 4 windows opened with out any action by me, I was on a highway, I again pulled over and was not able to close the windows. After I continued driving I was able to close 3 of the 4 windows and eventually the 4th. This is a safety issue.
