My 2015 GMC Canyon sle pickup has a backup camera dimming problem. When backing out of my garage on a sunny day, the large display of what the camera sees behind the vehicle is bright and it is easy to see any objects located in the backup path until the vehicle reaches the location where the sun light falls on the dash. At that point the display dims to the extent where it is difficult to see any objects in the display. The dim display lasts for about 15 seconds when it instantly returns to full brightness as was visible in the garage. If one puts on sunglasses in the garage, in anticipation of sunlight outside, then the display dimming appears so severe as to not be able to see any objects in the display, until the display brightens after about 15 seconds. The word "objects" here means anything reasonably discernible on a typical driveway or roadway surface including children. The problem may be related to the light sensor on the dash used to automatically turn on lights in darkness, because when backing out of my garage at dusk the vehicle headlights are on and the backup camera display does not dim. Two videos showing the above problems at daylight and dusk are about 30 to 35 mb each and too large to upload here. The problem continues today.
