When shutting my door and especially moving and hitting very light bumps in the road at all speeds the headlights shake on my truck . I have the hid headlights and it is very distracting to me and probably to other drivers . I only have 500 miles one my truck .

Headlight beam shakes constantly while driving at night. Dealer addressed issue several times with nothing being accomplished as the lights have continued to shake. Headlight beams shaking is very distracting during night driving and the shaking is quite unsafe as you cannot maintain a consistent, undisturbed beam of light in front of the vehicle at times when same is absolutely mandatory.

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.

Hid headlights shake when hitting the slightest bump in the road. Gm says it's normal and refuses to try to fix.

Headlights shake when going over bumps in highway. Its distracting and irritating and takes your attention from the road when it happens.

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 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.

These headlights are horrible. Very hard to see on a wet dark night, compared to the 2009 GMC Sierra 2500. Complained to the dealer, found a TSB for computer reflash to turn up the voltage to the bulb. Mild difference, but still not very good for a $50k vehicle.

The contact owns a 2015 GMC Sierra 2500. While driving at night, the headlights became very dim. The vehicle was taken to the dealer where it was diagnosed and repaired. The entire headlight assembly was replaced; however, the failure recurred. The manufacturer was notified of the failure. The VIN was not available. The failure mileage was approximately 27,890.

The headlights offer very poor performance at night.

The headlights are not bright enough to light the roadway sufficiently at night while driving, especially on dark rural roads and during hazardous weather situations such as rain or fog. The dim light does not allow the driver to effectively see road hazards, pedestrians, bicyclists, animals or other obstacles that may appear and thus is a safety hazard.

The headlights on the GMC 2500 hd are not bright enough. The lights are not able light roads without street lights, makes it very dangerous. Fuel filter has been replaced twice and my truck only has 12,000 miles on it. When I asked with the life of a fuel filter should be I was told by the GMC dealership at least 15,000 miles. It is possible there is a malfunction within the senor for the fuel filter.

The headlights on 2015 Sierra 2500hd denali are safety hazards they do not illuminate far enough ahead of you at night to see road hazards in front of you at normal driving speeds, they are especially lacking on rural roads, where animals might be on the roadway. They barely illuminate (very dim and unreadable), the license plate on a vehicle in front of you traveling at regular night time distances, giving you very little reaction time to react in case of hazards. We have a new vehicle less than 3000 miles and find this vehicle very dangerous to drive at night or in poor lighting. The dealer told us there was nothing they could do, considering trying to find some type of after market lighting to add to the vehicle to aid in night time driving.

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.

While driving at night on rural highways, towing my fifth wheel trailer, in az, CA and or with no other light sources nearby the headlights were dimmer than those I am used to making wild animals and people along the road difficult to see. The instances when I noticed this were all in September 2015 . This morning my dealer, robideaux motors in coeur d'alene, id, checked out the problem and told me that the lights appeared the same as other similar models and they could not duplicate the issue (repair order #193940). I was not surprised as I have seen numerous similar reports on internet blogs and I even understand gm is being sued over the same issue (2013 and 2014 models) in a case in California.

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.

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.

The headlights do not provide adequate lighting of the road which makes it very difficult to drive safely at night . I have tried to work through GMC they changed the bulbs to a different vendor but didn't help. GMC now in the 2016 are using hid bulbs they also used a different lighting system in the 2014 . The local GMC dealer agrees that the lighting could lead to possible accident . The lumen of the bulbs are down around 1200 which is half of the normal lumens to provide adequate stopping or visual of the road. Please help us owners as this vehicle is very dangerous to drive after dark.

Headlights aren't wide enough making it very dangerous to make a left or right turn and very dangerous in mountainous areas GMC finally put brighter bulbs in and hasn't fixed the problem. This has been ongoing since may 2014 and gm doesn't care.

The contact owns a 2015 GMC Sierra 2500. While driving various speeds, the projector headlights failed to adequately illuminate the road. The vehicle was taken to the dealer where the tcm and bulbs were changed per TSB number: pit5374 (exterior lighting). The manufacturer was made aware of the failure. The failure mileage was unknown.

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

Vehicle low beam head lights have very poor coverage and brightness. When driving at night they barely light the road in front of the vehicle. Coverage side to side is very weak. Additionally when it is raining out, it is like driving with no headlights on at all. I have contacted the dealer and they have indicated this is common complaint on 2014 sierra 1500’s and all 2015 sierras since the last redesign.

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.

I am writing regarding an issue with my 2014 GMC sierra. I purchased the truck in 2014 and have noticed an issue with the headlights while driving at night and in the rain. The headlights do not provide enough illumination when driving at night. Is there a service issue or recall in place to fix this issue? I have requested that the headlights in my 2014 sierra be replaced with the 2016 headlights. This is a severe safety issue that needs to be addressed immediately. The dealer is willing to change the bulbs in the lamp but not replace the lamps same as the 2016 model unless there is a service bulletin or recall. I am still working with the dealer as well as GMC corporate to address the issue. I am been flashed by other drivers to indicate I don't have headlights on but they were on as well as being pulled over by the highway patrol who though my headlights were not on. I have noticed other complaints on GMC message boards as well as other places online. Please look into this issue to see if it can be addressed. The only way GMC will address it is by recall or lawsuit.
