Fully enclosed LED tail light (turn and brake integrated into 1 LED "strip") with no visible moisture ingress/egress system showing retained moisture and no longer functional. Dash light for "rear signal brake light failure" appears. This rear light unit is NOT serviceable or repairable when a light goes out and is fully sealed aside from the reverse light (incandescent bulb and functions fine). LED's should have a lifespan that outlives the vehicle and a major incentive to have LED integration with lighting is the lifespan and reduced need for service. Now the taillight and brake light stop working and can not be fixed without spending <$500 per side. This is a safety issue that seems to be closely related to the issues with the GMC Yukon's of the same generation.

While making a quick left hand turn at low speed, steering wheel suddenly locked, all lights and electrical went out and engine died. This left me stuck in a busy intersection with no lights. I was able to restart engine after a minute or so. Error message appeared "roll driver side window up, etc." Needless to say, no longer have confidence driving my truck not knowing when this situation may re-occur.

Display screen to bright when vehicle is in reverse. When putting vehicle in reverse the backup camera display is so bright you can not see your exterior mirrors or out any of the windows to see surrounding area. This is very unsafe condition because you are blinded while backing up. When took the truck to dealership I was told they can't duplicate this. And have had no other complaints"?"

On screen display for backup camera. When putting the vehicle in reverse, the on screen display is so bright that you can't see out the windows, the rearview mirrors or the surrounding area. This display does not dim with the rest of the lights. This causes a severe safety hazard when trying to backup the vehicle.

During night operation with the instrument cluster adjusted to proper brightness the intellilink screen is dangerously bright. The intellilink screen does not have an independent brightness control from the dimmer. When set to off in an attempt to mitigate the problem, the intellilink screen reactivates with subsystem adjustment, e.g. temperature adjustment, absolutely destroying night vision of the driver. If adjusting the brightness level to acceptable for the center console lighting and intellilink the instrument cluster is so dim that it requires unsafe levels of driver attention to process the dimly lit information. In addition the backup camera is also too bright as well in reverse causing a distraction. GM customer support was notified and confirmed this was as designed without a dimmer and they will file a complaint as per my request.
