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.

Headlights are extremely dim, even on the high-beam setting. Makes it extremely dangerous to operate at night and I will not drive it at night unless it's an emergency due to not being able to see.

The headlights on this truck are terrible, both lack of side projection and front projection are unsafe especially when driving in rural areas or during wet road conditions. I have had the BCM update and new bulbs installed from GMC but this offered very little improvement. Driving with the fog lamps on offer the only lateral vision to see turning any corner.

From the factory the headlights that come on this vehicle are sub-standard and a safety hazard when operating at night. Not only is light output poor, but the width of the beam is horrible. When turning at night there is zero coverage and you have to make your turn without being able to see properly. These problems persist at any time headlights need to be utilized.

Head lights are very dim and I can not safely see the path I am traveling. An upgrade was performed at the dealership which helped somewhat but I still can not safely see the path I am traveling. I dread driving this truck at night and do not feel safe doing so.

The high beam headlights, as installed from the factory and properly adjusted, are inadequate for driving on dark country roads at night, in the absence of ambient lighting from street and yard lights. The light is cast well down the road, but there is too little light spread to the shoulders of the road, making pedestrians and animals difficult to see if they are not directly in the roadway. I live in a rural area with many peach orchards and pastures, therefore there are often few, if any, street or yard lights to provide any ambient lighting. Also, many of the roads in the area have neither painted lines nor reflectors to help mark the path of travel at night. If there are hills and curves, the light pattern and output of the factory installed lights on my 2014 GMC Sierra make it difficult to distinguish unmarked pavement from the grass on the shoulders of the road. All of these shortcomings are magnified when roads are wet and/or it is raining or otherwise inclement weather. I approached my dealer here in spartanburg, SC, about a remedy for the inadequate headlights, but the representative was dismissive and did not follow-up.

The contact owns a 2014 GMC Sierra 1500. The contact stated that the low beam headlights were very dim. The failure recurred numerous times. The vehicle was taken to the dealer where it was diagnosed that the headlights needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was notified of the failure. The VIN was unknown. The approximate failure mileage was 20.

I almost hit a deer when the vehicle was new as I could not see it until it was next to the passenger door, standing still. I had the dealer adjust the lights three times and install the GMC update, on the computer. I now have a blob of white light fall on the center line and another blob in the center of the driving lane. There is no light illuminating far forward or to the sides as should be. I talked with the dealer and there are no further updates for now. I have since had several close calls. I have driven professionally in the past.

Today for the first time I drove my 2014 Sierra Texas edition in the rain at night.... wow>>>>> I had to stop and wait for the rain downpour to let out so I could see where I was going. Not good. Driving at night is very stressful and eye straining to the point of taking headache medications once you are done driving. Any way to fix this extremely dangerous problem" this should be considered a safety hazard to drivers and any others on the road. This issue needs to be addressed and resolved asap. And GM still says there is nothing wrong. So why are they changing the design on the 2016's trucks after contacting [xxx] to see if he could provide some help this is what he had to say hi [xxx]: thanks for watching! the best way to solve your problem is to install a set of led auxiliary driving lights. They can be purchased for about $300 plus labor and make a world of difference. At least that"S the way we have addressed the problem on those trucks in my shop.

The projector beam headlights on my 2 year old GMC Sierra are, and have been, noticeably dim to the point of being a safety concern. It's as if trying to drive at night while wearing dark sunglasses. In addition to being dim, there's also the problem of side illumination. I can see some of the road ahead, but can't see the ditches on either side of the road. I consider this lack of side illumination to also be a safety issue, especially when negotiating turns or curves. Using high beams offers little, if any improvement. The high beams only seem to shine higher (tree top height), but offer no real increase in either side illumination or actual brightness. The "eye lids" lift, but poor illumination remains unchanged. About the only option is for me to drive with the fog lights on. Using fog lights at least gives a bit more side illumination, but still does nothing to assist with "down the road" illumination. I've been surprised at such poor lighting being installed on an otherwise great truck. These projector beam headlights were supposedly offered as part of premium packages. If these headlights are GMC's best, I'm sure glad I didn't get the cheaper lights! my only hope is that GMC will offer some type of headlight upgrade, possibly led lights.

Headlights are dangerous! dealer performed update( new bulbs and increase voltage to BCM) but improvement was minimal. Have even tried led conversion, with very litle improvement. I have had several veihcles with projector system, and had zero complaints. I have looked a projector lens on other vehicles, and they do not have impurities (tiny air bubbles) in the lens. I believe the problem lies in the sub-par lenses.this creates an extremely dangerous situation for night driving.

I traded a 2011 GMC Sierra on this 2014 GMC Sierra (sle / double cab / 4.3L V6), plus still have a 2012 GMC Sierra, and the lights on these 2 when compared to the 2014 GMC were / are like night and day - the 2014 GMC Sierra is positively dangerous to drive at night - lights are disgusting - high beam on 2014 GMC is worse than low beam on my earlier GMC Sierra's. took copy of "" report on headlight problem to dealership, but they said GM has not provided them with any info' of "supposed" problem, nor can they offer a solution. Have reported this problem 3 times - no action, an no concern either, in my opinion.

Clock and outside air temp readings are so small, you can't see them, without taking your eyes off the road, long enough to bend over close to the radio. This is as bad as someone using a cell phone to send and receive text. I have driven off the road twice, but have not crashed yet. My GM dealer says, the readings can not be made larger, and to be very careful.

2014 GMC Sierra 1500. Consumer writes in regards to vehicle headlights design problems. The consumer stated he discovered the headlights only had one bulb, which meant the high and low beams had to be adjusted as one unit. He exited the vehicle and measured the distance from the vehicle to where the visibility ended. The distance was 130 feet on both sides of the road. Also, on a turn of 90 or 120 degrees, there was no side lighting which meant he had to slow down to a crawl in order to make a turn. In addition, when going down hill, the visibility of the lights decreased to about 20-20 feet. The dealer raised the lights about factory specs. He could see a little better, but the high beams were 20-30 feet in the air and were useless. MA 08/05/15 the consumer stated during inclement weather visibility decreases to 20-30 feet/40 feet max.
