This morning when I used the backup camera it was perfectly fine. Once I get to work and started backing up at a slight turn bc I was parking next to another vehicle it gave me a blue screen saying 'service rear vision system'. it also does this while stationary. This is a highly unsafe problem to me, because it doesn't allow me to operate the vehicle safely putting me and others at risk.

The rear view camera is fish eyed and the resolution is terrible especially at night. The dealership at first said that the camera was operating, after contacting GMC they looked at it and now say there is a problem. Now I see that they are having problems with these camera.

The backup camera on the infotainment system is blindingly bright at night. When you put the truck in reverse the backup camera pops up on the infotainment screen and blinds you making it a huge safety hazard as you cannot see anything out your mirrors. This needs corrected so there is a brightness control to allow the screen to be dimmed so that you can see when backing up.

Gps infotainment screen is to bright at night and there is minimal adjustment that also dims the instrument cluster so that you can't see it and controls. After dimming everything together instrument cluster and the gps screen and placing the vehicle into reverse the screen goes into full brightness if you put it in drive the screen goes to the front camera and is dim like it was before placing it in reverse. There is no contrast or dim option for just the infotainment screen. The only option is auot day night all are very bright and dull gray looking lacking contrast. It's very difficult to drive at night with this screen blinding you non stop the only thing you can do is place a rag over it. I can't drive the truck at night it is very distracting to me and I don't feel safe.

My 2018 GMC Sierra has vibration at highway speeds 60-75 mph. After several hours of driving the vibration can be felt as low a 20 mph and up to 75 mph.

When I am driving my truck, I will get notifications saying that there is a trailer disconnection issue when I don't even have a trailer connected. It also flashes an alert saying that the lane departure system and pedestrian sensor are being effected. As this is going on, the infotainment screen flashes on and off as well which is very distracting. They have continued to come on in cold weather after I have taken it to the dealership to be looked at. I don't know if this is a hardware or software problem but it needs to be addressed because it becomes both a large nuisance and safety hazards when you have errors messages and lights flashing while you're driving.
