Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

These trucks have the worst headlights that I have ever owned and something needs to be done before someone is hurt or killed.

I purchased this truck new in October, 2014. My research prior to purchase showed a number of complaints about the headlights, but I did not think there were enough complaints for me to be concerned. I was wrong. I live in a rural area and the headlights are definitely inadequate on the low beam setting. The mechanical shutter design produces a very sharp beam cutoff at about the level of the hood, making it seem like you are sitting in a darkened area above a bowl of light. The projector headlights provide little, if any, illumination of objects on the side of the road. I use the fog/driving lights continually on the truck or I would not feel comfortable driving it with low beams in unlit areas. For the sake of comparison, I have attached two images taken on two consecutive mornings at approximately the same location on my driveway. The truck picture was taken approximately ten minutes later than the car picture (both were approximately 6:45 a.M.). note there is a slight perspective shift due to the height difference in the vehicles and the driving/fog lights were not on on either vehicle when the picture was taken. Note the 25-year old technology sealed beam headlights show the fence posts at the right side of the vehicle where the GMC's headlights show a dark void. It honestly feels like you are driving through a tunnel of light in the truck. You have no hope of seeing any objects on either side of the road. There is a tsb on this issue that recommends replacing the bulbs and reprogramming the BCM. My truck has not had this performed because the dealership did not have the bulbs in stock when I asked about it. There is some debate on message boards regarding whether or not the update offers any benefits. Additionally, the new bulbs allegedly have a significantly shortened life over the originals and they can be difficult to locate when needed.

The basic design of the headlights does not allow for a sufficient level of lighting to safely operate the vehicle at night. There is virtually no lateral lighting, and the headlights do not illuminate the way forward, they only drop a shutter in front of the lights when one switches from low beam to high. There is no increase in light intensity or volume when switching to bright lights. Recall and fix!!!!!!

The headlights on this truck are inadequate for driving at night. If it's raining at night, I won't drive it. I bought a new truck from GMC, it's unsafe to drive at night, and GMC should fix it !!

There truly is no accident at this time. However... if this condition isn't corrected, there will be accidents. These may result in not only loss of life or property, but possible criminal prosecution. The issue: The projector headlamp design of the 2014 GMC Sierra is extremely subpar for lighting the roadway ahead of you. Individuals, in order to not "outdrive" their lights, would probably have to go below posted minimum speed limits on highways, presenting yet another issue for the driver as well as those who would approach from the rear in nighttime driving conditions. I contacted GMC... aware of the issue. No help at this time. I got the impression from the operator that "not enough people have filed complaints." I'm guessing that when the catastrophic and tragic happens, it will not matter that not enough people filed complaints... officially. Slight research on the internet will show many individuals complaining about the issue. But GMC's admission that they are "aware" but are taking no action at this point is very disturbing. I would have thought that design issues would have had to be cleared by an oversight Agency of some sort" I just discovered the extremely scary feeling of "driving in the dark"... basically... after having my truck since thanksgiving. But I drive mostly in the daylight, and have been on interstate 20 in one of the busiest sections with traffic at night... not realizing how much others' lights were helping. When driving alone on a rural road, however, it is tantamount to driving with a flashlight when it comes to safety. I am wanting to trust that the Agency tasked with safety will please look into this issue? before someone or multiples lose their lives and lawsuits ensue"

Vehicle has poor headlight performance when driving at night. Has been back to the dealer multiple times since purchase in 2014. Reprogramming and headlight bulb replacement was ineffective. Not safe to drive in rural/dark and or rain/snow/dark.

The contact owns a 2014 GMC Sierra 1500. While driving 65 mph, the headlights became unresponsive and produced dim lighting on the road. The failure hindered the contact's visibility. The vehicle was taken to be repaired, but the issue recurred. The manufacturer was made aware of the issue. The failure mileage was 35,600.

Headlights are terrible. In a dark rural area, they are so dim they are dangerous. You can easily outdrive your headlights. In the dark and rain, you should stay home. It's sad I can't drive my $50,000 truck at night. Dealer's "fix" was worthless. So angry. I will never own another GM vehicle!

Extremely poor/unsafe headlights. I have been dealing with this issue since purchased new. "lurking" in forums and complaint web sites assuming a fix would be forthcoming. I guess not. Insufficient lighting at night in rural settings with no ambient light. Cannot see anywhere near the distance required to drive safely at posted limits and non-existent side lighting. 2 near misses with deer grazing on side of road as proof. I spent the money for good auxiliary driving lights and a light bar to put them on but are only useful with no oncoming traffic. Current replacement bulbs/BCM reprogram cause limited improvement with significant increase in bulb failure frequency. 2016 redesign eliminated these lights and retrofit to 2014/15 hardware is available. GM should step up!

I have returned my GMC crew cab Sierra 2014 to the dealer 5 times because of inadequate headlights. The first time they service dept. Readjusted them with no improvement. The third time back the bulbs were replaced per a bulletin and BCM reprogrammed. Still no improvement especially on the right side. The fourth time I had my intelligence insulted when the service adviser told me it was because the garage door he shone them on was dirtier on the right side. What an excuse and only a fool would insult his own intelligence with that remark. The fifth time back the parts manager had ordered a new bulb for the right side and was consequently replaced a second time. I wrote a certified letter then to GM customer service and was contacted by mark 1-866-522-0300 ext.#5921569. He said I was supposed to take the vehicle to the dealership and leave it so they could drive it at nite. I did that and it was driven by paul and upon contacting him this am he told me the low beams were absolutely terrible and overall the headlights on the truck were as lousy as all the 2014 and 15 trucks are. Upon picking the truck up this afternoon the same rediculis service advisor (wally) told me that he didn't drive it and paul did and told him there was no problem with the lights. Who is the liar? isincerely believe it is wally because he is bound and determined not to fix it. The high beams on this vehicle are what the low beams should be. This is a safety issue and a $53000 truck should have safe headlights. On low beam there is a black curtain only a few feet from the hood and going downhill that black is almost at the end of the hood. I have over the past 18 months talked to four GM reps at the customer service center, with the third one telling she would make arrangements to replace the light system with the 2016 system. She called the dealer setting it up and then never followed through.

The headlights are not bright enough for night driving on country roads without street lights, on bright or dim mode. These are the worse headlights on any car I have ever owned, I personally have bought 4 brand new GMC pickups, this is the worse. I never thought about test driving at night, I trusted them, wrong!
