Headlights were about as bright as a candle while using high beams changed the bulbs and used a head light restoration kit and within a week headlight lenses were hazed over again high beams are no brighter than low beams

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.

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.

The headlights are to dim and unsafe on dark mountain roads since new.

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.

Tl* the contact owns a 2015 gmc sierra 2500. The contact stated that the headlights were extremely dim and prevented the contact from viewing the road while driving at night. The contact was concerned that a crash could occur. The vehicle was taken to the dealer where it was serviced for a manufacturer update related to the headlights; however, the failure recurred. The manufacturer was notified of the failure. The failure mileage was unknown. ...updated 12/28/16 *bf the consumer stated the lights are ok. However, they could be a lot brighter, because it is still hard to see at night. Updated 01/03/17.

The low beam projector headlights are inadequate, especially in rural areas. There is a distinctive cutoff of light, call it a line when on low beam, and beyond that line their is no illumination whatsoever as you would be used to with other lighting designs. You can not see any signs, possible animals, or anything else as you are used to seeing in the light that typically extends beyond other low beam systems. I understand that gm has a tsb for the condition but it is not advertised and from what I can determine on the net does not work regardless and is only a band aid fix. These lights are a safety hazard. I believe this issue may have contributed to an accident I had. ..updated 01/04/17

The headlights on the truck are a serious hazard. While driving at night you can only see about 20ft out in front of the vehicle. It's even worse when is raining.
