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.

The contact owns a 2014 GMC Sierra 1500. While driving various speeds, the low beams and high beams were extremely dim when activated. The failure recurred continuously. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 30. Updated 6/22/15

The headlights do not illuminate the road enough. Very dim and cannot even tell where cut off line is. Even with fog lights on, it is unsafe to drive at night.

The headlights on the 2014 GMC Sierra 1500 are not adequate for night time rural driving. On 7 Oct 2014 at approx. 5:30am a deer ran into the side of my truck hitting just behind the driver's side front wheel because I was not able to see it in time to avoid hitting it because of the poor headlight lighting design of the truck. If the headlight lighting design on the truck was adequate I would have been able to avoid hitting the deer.the low beams do not light up the shoulder of the road enough or in front of you for more than approx. 50' to 75' (that's probably being generous) and the high beams are just as bad and point up in the air. The NHTSA should immediately do something about this and make GM fix this problem before someone is killed or seriously injured or is that what you are waiting on to happen before you do something about this problem. I know you have received numerous complaints about this problem and so has GM but to date I haven't seen any action taken. Is this gonna be another cover up by GM with your help because both you and GM are aware of the problem before you take action or are you gonna do what you are suppose to do and keep us safe on the highways. It was the govt that bailed them out when they were going bankrupt not so long ago so why isn't the govt (NHTSA) helping the public now and bailing us out to fix this problem.

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"

Headlight lighting is useless, night driving is dangerous. Light output is so low/dim that it is easy to out drive the headlights. High beam is no better as it just disperses the beam actually making it appear dimmer. Something needs to be done to address this concern before someone gets injured by these unsafe headlights.

The headlights on this vehicle are horrible, low beams are of no use except in the city traffic and high beams are only slightly better. High beams are not sufficient for driving on dark roads. Hopefully GM will offer to repair/replace these before there are deaths to report.

I've had my 2014 GMC Sierra for nearly a year now, first night I had it I couldn't believe how poor the light output was from the headlights. I've had numerous GMC Sierra trucks over the years and this truck by far has the worse headlights I've ever had in a truck. There are a lot of people online complaining, I'm definitely not the only one upset with how poor these headlights are. There are a few guys in town with this same truck they all hate the headlights too. These headlights just seem very dim, they don't shine the ditches up very well, they don't shine ahead very far either. I have better luck running the headlights on low beam and fog lights on, it almost seems like less light on high beam so I rarely have them on high, I've had multiple occasions where I nearly hit a moose, these headlights are very dangerous I'm worried that one of these days I'm going to hit a moose or worse a person! I really hope somebody does something about these headlights GM didn't listen to anything I had to say.

The headlights on this truck are horrible. I can barely see the road or sides of the road. At night cars behind/beside me flood out my lights. I have the interior lights turned completely down and still the lights are very weak and dangerous.

The factory headlights are almost useless at night especially if there is any moisture on the roads. They are absolutely horrible at dusk and dawn as well.

The large 8" intellilink radio screen in this truck has separate brightness control from the rest of the dash lights, including the instrument panel. Due to it's size and colored background, the lcd radio screen is much brighter than the rest of the interior lights. The fact that the system has no night scheme, meaning it doesn't shift to a mostly black background at night makes this problem even worse. While it is possible to lower the brightness using a dash-mounted dimmer switch, the dimmer must be lowered to minimum in order to get the radio screen to be a comfortable brightness level for night driving. At this point, the instrument cluster lights are so dim as to be extremely difficult to see and as a result require much more time and effort to read speed information. The only way to completely turn off the radio screen is to go through several menus into settings and manually turn off the screen. Not only is this a dangerous distraction while driving but if any vehicle setting such as radio volume, or HVAC controls are adjusted, the screen automatically turns back on and the process must be repeated. I have contacted GM several times about this issue due to its distracting nature when driving at night and have been told repeatedly that the system is "operating as designed." I feel this is a safety issue since the bright light in the cab ruins night vision while also distracting the driver's eyes from the road. My recommendation is for a software update for the intellilink/radio system to be designed to add a brightness setting in the system menu to allow driver's to set the radio screen brightness independently of the instrument cluster lights and to also program a "night mode" color scheme that would shift from the blue illuminated background used in the daytime to something that is mostly black.

The projector style headlights this truck is equipped with are insufficient for safe night driving when not in a city driving condition. The low-beams are satisfactory for lower speeds (ie <45mph) but are extremely easy to out-drive at highway speeds. The beam pattern is also not wide enough to illuminate anything other than the area directly in front of the vehicle. The high beams are even worse. The headlights in this truck use one single filament bulb for each headlight. When the high beams are turned on, a mechanical shutter opens to allow more light through the projector lens. The lens is designed such that this additional light is aimed so high as to be useless. Parked 20ft from a wall, the center of the high beam patter is already several ft above the bulb level on the wall. When driving on a straight and level road with no trees, it is actually impossible to even tell the high beams are on since there is no extra beam to illuminate the sides of the road and the center beam is pointed up into the trees.

Headlights do not provide adequate illumination for night driving. Should be considered a safety hazard to occupants and others on the road. Poor design and/or specifications on GM's part to allow the usage of this headlamp configuration on any vehicle on the road today. This issue needs to be addressed and resolved asap.

When I first started driving my new 14 GMC I had never had a truck with projector headlights so I was unsure if it was just me that had to adjust to the beam of light they provide or if it was a problem with the lighting itself. After having driven my 14 silevrado work truck with standard lights I realize there is a huge problem with the GMC projector lights they are so bad it makes you think there is a faulty ground wire or something extra ordinary wrong with the headlights. It is so bad that I even looked into upgrading the bulbs but you can't even do that because philips owns the rights to produce them and wants to over charge the aftermarket for the use of the design, so I am stuck with a headlight system that is worse then a 6V headlight from the 40S.
