The headliner fabric detached somehow from the panoramic track causing the fabric to hang down obstructing the rear and back window view causing a safety hazard. The automatic forward collision alert will come on for no reason since this has happened. The problem has not been reported to insurance or the manufacturer yet but gm is my next call. This is a safety hazard due to the obstruction of visibility to safely make turns or change lanes. This happened August 5th while driving with the windows up. It just dropped down still attached to the front of the track and the rear.
My driver seat does not raise or incline so it gives me like a visibility when I’m driving. The seat needs to be raised so I have more visibility on the road while I’m driving.
At night while stopped, as you shift the car into reverse, the rear view camera display is blinding bright. Its bright light is being reflected by the windows back into the car, making it impossible to see out the windows of the vehicle. While other car functions - radio, phone, and navigation - which all use the same display screen as the backup camera, dim themselves for night use, the rear view camera display is as bright at night as it is during the day, causing this issue. This is a permanent, repeatable issue.
