The lighting on the entire interior infotainment area will randomly go bright and dim all by itself. I was almost in an accident on the interstate due to this. It was blinding and distracting to have the lighting dim and then go bright. It has been randomly doing this for about a month. I called GMC and they said they had no record of this happening on other vehicles, however when I searched for the issue with my vehicle, I realized other GMC owners have experienced the same issue. I was able to get a video of it happening one morning while waiting in my driveway to drop my kids off at the bus stop. I was in the parked position. There are no warning or messages when the lighting malfunctions, so I am not at all prepared when the car turns the lighting to MAX brightness. It poses a risk when driving by blinding the driver, causing the driver to loose focus while driving trying to adjust the lighting back to dim. It is an unnecessary distraction. The dealership couldn't confirm any malfunctions in my car. As previously stated, I have a video of the malfunction, but I am not able to upload it. I am willing to send via email.
