GMC Sierra owners have reported 67 problems related to headlights (under the exterior lighting category).
The vehicles headlights are dangerously ineffective. They rarely illuminate the distance between 2 telephone poles. The ineffectiveness of the headlights is amplified on hills or on any turn. The during the transition from decline to incline, you sometimes have barely a trucks length of illumination. Any corner on a dark road requires a severe decrease in travel speed to avoid over driving the lights. I have never driven a vehicle that made me feel more apprehensive to get behind the wheel after dark. I visited the dealer who executed a TSB that increased headlight voltage and replaced the bulbs. It made a negligible improvement and left the vehicle still unsafe at night. I frequently travel on rural roads with no street lights. I have almost hit wildlife too many times to count due to the poor visibility caused by these dangerous headlights. Travel over 30 mph on dark country roads with a legal speed limit of 50 is ill advised due to the ineffectiveness of the headlights.

Headlights are not adequate for night driving: have driven this truck for the past year at night and in different types of weather and have had to really strain my eyes to keep it on the road due to poor visibility due to the head lights, after missing a turn last night off the highway decided to see if the dealership would take a look at them and see what they could do ,if they say there is nothing that they can do ,ill have no choice but to install different headlights .
The headlights on this truck are terrible. Very dim light, can't see to side while making a turn. The high beams doesn't make much of a difference. Contacted GMC directly and they just refer me to th dealership. Looking into after market lights. Looks like they may not be legal. So many complaints when will something be done?.
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.
I purchase this vehicle Nov. 2013, and ever since I notice that the headlight on this vehicle do not light the road properly, whether you have them in low or high beam. The distance of the low and high beam appear to be the same (at times it seems the highs) are aiming skyward. Not to long ago I almost ran over a woman and a child who were crossing a street over to my left when I was attempting to make a left turn (this was a dark area). Luckily I was going slow when I was making the turn and was able to see them when the headlights hit them and came into view. By this statement I am trying to point out that there no lighting to either side of the vehicle, I am sure (positive) that if I would have been making a right turn an accident would have happen. Are there any recalls regarding this problem? if not, I think there should one. Because if something like this example I am submitting to you ever happens, the driver will held responsible. An in my case it will be blamed due to my age.
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.
The contact owns a 2015 GMC Sierra. The contact stated that the headlights low beam failed to provide adequate light coverage making it very difficult to drive at night and the high beam also failed to provide sufficient light coverage. The dealer advised that the headlights were operating as designed. The headlights were not repaired. The manufacturer was made aware of the failure. The failure mileage was 731.
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.
I have two 2014 GMC Sierras with very weak headlights. Called gm and they said nobody has complained. They lied. Wake up gm and smell the roses before someone is hurt or killed. The headlights look great but work bad. Feel like it will be forever before they do anything so I added my own aux. Lights. My my I can see again. Spent 400. 00 dollars on 45,000 dollar truck so I can drive safety at night. 2014 chevys have duel headlights. Must be better. Fix the problem gm. My first car, a1962 comet had better lights.
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.
The contact owns a 2014 GMC Sierra. While driving various speeds at night, the headlights were dim and caused poor visibility. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The VIN and failure mileage were not available.
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!.
