The instrument cluster lighting presents a hazard at night. The dimming system does not sufficiently dim the cluster. The glare interferes with the driver's vision to the outside of the vehicle, especially while driving on rural roads which lack ambient light. This has been confirmed by both the dealer and GMC customer service as being the way it is designed.
