I recently purchased a 2015 GMC Sierra K1500 slt. I selected the slt for the projector headlights which are not offered on the lower trims for improved lighting. However, the headlights have extremely poor illumination (cannot see off to the side of the road, very dim, poor projection in front) in low or high beam. The headlights are the worst on any vehicle that I have owned over the past 35 years. I almost hit a deer on the road at night, driving 35 mph, because the deer could not be seen in the visible arc of the low beams until too late. The deer was standing on the road fog line. I located a GM document on several truck forums concerning this issue. Original document # 4093100, pit5374 (2/27/2015) and followup document # 4109395, pit5374A (3/9/2015).

During night operation with the instrument cluster adjusted to proper brightness the center console lights and most notably, the intellilink screen are 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. Dealer verified issue on two service visits but unable to correct per manufacturer. Safety complaint registered by me with GMC infotainment customer support.
