Headlights are not safe to be used in the dark. Driving on curvy, hilly roads is very dangerous. Can not see well. High beams barely different from low beams. Live in town so this was first time out on road at night. Scary. Can't imagine what it would have been like in rain or snow storm.

I bought my 2014 GMC Sierra brand new in Dec 2014 and had it back to the dealer within 3 weeks because I was sure there was a defect with the headlights ! you can only see maybe 30 feet in front of you and nothing if you make any turn on a dark road with no streetlights ! the mechanic at the dealership said there was no problem with the lights and they meet all general motors specifications . . . I have read many many complaints from other 2014 GMC Sierra owners with this same complaint so I know its not my imagination or a problem with my eyesight !! I sure hope that GMC doesn't wait for fatalities or a class action lawsuit before addressing and correcting this problem , I have been a loyal GMC consumer for 45 years but this obvious problem with the lighting and GMC's refusal to acknowledge that there is a design defect I can say this is the last GMC vehicle I will ever purchase . Do the right thing general motors ! fix the problem and save some lives !.

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?.

The projector headlights on this vehicle are terrible. They are dim and have a very poor light pattern. (the bulb presumably meets federal standards, but the projector system was designed for a brighter bulb). It is very difficult to see the sides of the road, or very far down the road, on roads where there are no streetlights. It is even worse on a rainy, dark road. Gm instituted a TSB (#pit5374, attached) in February 2015 which involves reprogramming the body control module (bcm) to increase the voltage to the headlight bulbs and substituting vosla hir 55 watt bulbs for the original stock 55 watt bulbs. The results are a minimal improvement. The new 2016 models have the same headlight design but have been upgraded to a hid bulb that cannot just be plugged into the 2014/15 headlights. The improved bulb and wiring is evidence the TSB did not really improve the lighting very much. (the internet is full of complaints about the headlights on this vehicle; recommend you google "GMC Sierra headlights" and see what you get!). I live in northern virginia and would be glad to come down to the NHTSA building on a dark, rainy night and give you a ride -- the problem isn't so bad in areas where there are streetlights, but it is terrible out in the country. Bottom line, gm should be directed to issue a recall that involves replacing the wiring harness and bulb with their latest design. The headlights in the 2014/2014 Sierra are hazardous to the people in the truck and to pedestrians along the road. Thanks for listening to my complaint, and please take action for safety's sake. (note: there is no specific time, mileage, mph, etc. , that this was noted. It is continual. I had the TSB performed in the summer of 2015 and noted minimal improvement at that time. ).

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.

The headlights on my vehicle are unsafe for night driving in unfamiliar roadways. Besides being very dim, anything 60-70 feet ahead of you can't be seen. There is a cutoff line that blocks roadside objects and the cutoff top bar that doesn't illuminate road signs or street markers. Imagine holding a shoe box to your face with both end removed and that describes driving with this unsafe system. I thought mine way an isolated case but "problems with GMC headlights" on the internet clearly shows a major problem that needs to be recalled and replaced.

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.

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.
