GMC Sierra owners have reported 59 problems related to headlights (under the exterior lighting category).
Headlight output is horrible at night time driving on the highway. It is flat out dangerous. The headlights are only adequate for city driving at night.
See all problems of the 2014 GMC Sierra.
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 and coverage side to side is very weak. Additionally when it is raining out, it is like driving with no headlights on at all. To have better head lights I would have had to buy special lighting option available only on a higher-up model of GMC Sierra truck. All modles of GMC Sierra 2015 trucks should have adequate headlights without having to buy the top/ more expensive model to get them. GMC should be required to recall all GMC Sierra 2015 trucks and refit them with adequate lighting before bad accidents occur as a result of this deficiency. I have never experienced such poor lighting with a vehicle driving at night or in rain. It is unacceptable on a new GMC truck.

The head lights on this truck are of poor design and are very weak. The lights do not adequately light the road ahead or the shoulders. They will become a contributing factor in crashes and deaths unless they are improved! I can't believe these headlights would pass the minimum standards for illumination if follow up testing is done in poor weather conditions.
I wish to complain about the headlights on this vehicle. They are really terrible. Low beam does not project far enough, and high beam seems to illuminate road signs at a distance, but not adequate for their purpose. Seems as they are more of a spotlight than a headlight. These are the most unsafe headlights I have ever had in 43 years of driving. Again, there was no accident thankfully, and I just wish to file my complaint and concern. Thank you.
The projection style headlights do not illuminate the roadway sufficiently enough at night to travel more than 30 mph. While traveling on rural and mountain roads you cannot see far enough to see obstructions, wildlife or pedestrians at night. The horizontal cutoff line of the lights on low beam does not allow you to see the tops of small rises in the roadway as close as 30 feet away. With this style of projection lighting there is no spillage of light above established light shade cover setting on low beams. It is completely dark above this line with low beams selected. This does not give the driver a chance to see objects in the roadway at a safe distance to allow for safe braking or avoidance. The high beam setting is pitifully weak in intensity. I must strain to see out at the distance necessary to stop at highway speeds. This means I must travel with high beams on when facing oncoming traffic on the interstates. I had two previous trucks of this same brand that had wonderful lighting and I sure wish I had that lighting on this truck. Gm is doing the motoring public a major disservice with this lighting package and endangering anyone and anything that may be on the road ahead of their trucks!.
This is my first time to have a vehicle with projector headlights. They do not light up the sides of road, and are not very bright in dim or high beam. This is not very safe when driving at night, even when the weather is good. I will not buy another vehicle with these type of headlights.
Headlights are very dim. Like having none at all. High beams are useless. I actually had to follow other vehicles lights to keep from running off the road.
Tl-the contact owns a 2015 GMC Sierra. The contact stated that while driving at 30 mph, the headlights were dim causing the contact to be unable to view the road properly. The contact was concerned for their safety. The failure recurred multiple times. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The VIN was not available. The approximate failure mileage was 12,500. Djr.
The contact owns a 2014 GMC Sierra. The contact stated that while driving at various speeds, the headlights were very dim and impaired the vision to see the road. The failure recurred on numerous occasions. The vehicle had not been diagnosed. The manufacturer was notified of the failure. The approximate failure mileage was 58,000.
The headlights are very poor. I have owned many cars and the lack of night vision with the 2014 Sierra is the worst of any car I have ever driven. I used to work on my family farm back in the 1980s and our old tractors and combines had better night visibility than my brand new Sierra. GMC, you must fix this now! I guarantee you will have a major lawsuit on your hands if you don't. This is such a simple thing to get right, do the right thing and recall all these vehicles and install proper headlights.
Headlights on high beam were aimed to high & pointed up into the trees. Low beams seemed ok. I finally took to a local dealer for some recalls and talked to them about complaints and they adjusted saying the lights were aimed to high. Drove vehicle yesterday and the low beams now have so little projection forward that I'm afraid at night, if anything came in front of me, I'd hit it before being able to stop. Will be taking it back to have lights adjusted up again and live with it until GMC does something. Reason it has taken so long to file complaint is I do not drive much at nights and did not think of filing complaint until I found this website and reading other owners having the same problem.
Wanted to update info on this complaint. I have been in contact w/dealer and they have agreed to replace both headlights, even though they consider this to be abnormal, with the agreement that if it happens on new headlights they will consider it normal and do nothing more! I feel this is a safety issue as it obscures the light and also that they are trying to bully me into an agreement I don't agree with. My vehicle has a bumper to bumper warranty and they are trying to exclude this issue in the future if I agree to have the headlights replaced now. I have contacted GMC regarding this and have yet to hear back from them.
Headlights appeared to be leaking, condensation and water droplets. Took to dealer for oil change and advised them of the headlight issue. Was told they were not leaking that the design of headlights caused this, bulbs burn so hot they have a vent for cooling. Because of the air flow through vent it brings in condensation & water droplets can form which can take 2 to 6 hours to clear! was told that they w/only replace headlight assembly, which costs $900, if its over 50% of the lens. I was told one headlight was over 50% and had water droplets, as well as a halo effect around the bulb that he had never seen before. However, dealer did nothing at the time as the lens was clearing up. I asked about the condensation obscuring the light output and therefore my vision and was told it would not affect it. After reading the other complaints regarding the headlights I feel this may be part of the problem. If the lens is covered inside w/condensation & water droplets, it does affect the light output. I live in the pacific NW where it rains 9 months out of the year and therefore we have moisture in the air all the time! I am now documenting the condensation w/pictures of the headlights every time I drive it.
The headlights on this truck are unsafe. They do not put out enough light on dark nights and especially on nights were there is rain. They do not reach beyond the edge of the road way past the fog lines,. Or extend that far up the road in front of the truck.
Tl- the contact owns 2015 GMC Sierra 3500 denali (na). The contact stated that while driving at night, the headlight failed to provide enough lighting causing the contact¿s visibility to be diminished. As a result, the contact was only able to drive the vehicle with high beams on at night. The vehicle was taken to the dealer. The technician stated that the head lamps were up to factory specification. The manufacturer was made aware of the problem. The vehicle was not repaired. The failure mileage was 290. Pam.
Headlights are insufficient. Driving at night away from the city is dangerous. Brighter and wider light patterns are needed.
It was the first time I drove this new GMC at night and I couldnt see anything almost hit a huge moose cause I didn't see it. The headlights are aweful and its terrifying to drive at night. Went to dealer and told them about the headlights they said they had numerous complaints but gm has no fix. These headlights are going to cause multiple accidents simply driving 45 mph feels like you can out run the headlights in high beam.
The headlights are so good, they helped to save the life of several deer which I could clearly see up ahead, just above the crest of the road. The deer started to dash across the road, which was not lit, and I could clearly see them and properly steered clear of the deer. The headlights on this truck are the best I have ever had !! I find the 2014 GMC Sierra as the most well equiped vehicle I have ever driven. My complaint is not really about the lights or how well I could see the deer on the side of the road, it's about the need for other brands of vehicles that are not equiped with these type of headlights. I believe this type of headlight system should be mandatory on all vehicles of all makes. GMC has done the world a favor. Now it is up to the rest to catch up and use this technology!.
Headlights on this vehicle are terrible. Very poor illumination for night driving. There should be a safety recall for these headlights, pickup is dangerous to drive at night. Headlights light up road about 50-60 feet and offer very poor side vision. High beams are useless and shine up in the trees and not on the road. Vehicle has projectors with only a flapper to change high/low beam. Ihave been driving for 40 years and have never driven a vehicle with this poor headlight design. I cannot believe headlight passed photometric design certification (maybe they did not) I have complained to GMC but they say headlights are working as designed. Headlight assemblies were replaced once and adjusted several times by dealer. Still no remedy to the problem.
Headlight are extremely inadequate!! very poor visibility especially on low beam!.
The headlight output on my new 2014 GMC Sierra is so bad that I cannot drive the vehicle safely at night. In fact, I only drive it unless it is absolutely necessary. Not only are the lights very dim but the shape of the beam is also very poor and awkward . With the current oem headlight equipment, this vehicle is unsafe to operate at night. I contacted the dealer and they told me there was nothing they could do about it . I can't even find a better bulb because gm has the patent and not even piaa can make a better bulb.
My complaint is with the how dim the oem headlights are. I have complained to GMC regarding the headlights and the response is that they are ok with how dim the lights are. Compared to other vehicles I own/have owned the headlights are extremely dim to the point of being dangerous.
The front headlights are insufficient for safety. They do not light the road sufficient to see objects in road above a speed of 50 mph. These are single bulb projector headlights and my old 2001 chevy silverado has much better lights. GMC should replace the lights with dual beam lights or add on a supplemental light system.
Tl-the contact owns a 2013 GMC Sierra. The contact stated that while driving at night, the headlights seized and the vehicle failed to accelerate. The vehicle was taken to the dealer but it was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 4,000. Pam.

The contact owns a 2015 GMC Sierra. While driving at 45 mph, the headlights were engaged but failed to fully illuminate. As a result, the contact's visibility was diminished. The vehicle was taken to a dealer who stated that the headlights were not adjustable for lateral movement. The manufacturer was notified of the failure. The failure mileage was 5.
