The headlights are completely inadequate. If you are taking a turn at night, the lights continue to stay straight with the direction of the vehicle instead of following the vehicle so that you end up taking a turn blindly and cannot see the curb or edge of the road. It is a totally unsafe situation. We have found that you may have a bit more visibility if you run with the fog lights on, but very little improvement. Please find a solution, additional headlight, as this truck is very scary to drive at night.

The projector headlights that are installed in this vehicle from the factory do not provide adequate visibility at night. I am unable to see more that 15 feet in front of this vehicle from a safety perspective. I have returned the vehicle to the dealer multiple times for repair. They changed the bulbs but stated they are working within design specifications and said that gm had used a new type of lighting system in 2015 but realized it is was not adequate and redesigned in later model year. If gm realizes they have a problem why will they not repair vehicles that they sold prior to realizing their mistake? In the rain at night there is virtually zero visibility. Gm needs to fix this problem as it is a major safety issue.

Right rear turn signal bottom socket heats up and causes an open to the top turn signal socket so the top turn signal quits working and causes the system to hyper flash.and indicate inoperative right rear turn signal in message center. Only repair is to replace wiring harness and sockets. System works fine in cold temperatures as the socket does not heat up enough. Happens with vehicle stationary and in motion. Contacted gm about it and got nowhere.

The headlights are so dim the truck is dangerous to drive at night. I drove in a snow storm last night and I couldn't see ahead of me. I was driving on a highway at 45mph.

Head lights are so poor when driving in rural areas and poorly lit areas that the lateral lighting is so poor that you are left to guessing where and what you are turning into, extremely dangerous to all, dealer where purchased new stats there is no fix, accident waiting to happen.

The headlights are unbelievably inefficient. They light a narrow path about 30 yards in front of the truck. Driving at night is scary especially in the rain.

Drove off the road because there was virtually no visibility in a dark subdivision. Gmc initially denied there was a problem with the poor headlights --I stopped driving the vehicle at night since the $60,000.00 denali truck was unsafe to drive in the dark!!gmc eventually said they had a "bulletin" on the problem and they replaced the bulb and recalibrated the lights. About a 15-20% improvement--I still will not drive the truck at night as it is still unsafe.
