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!.
Headlight are extremely inadequate!! very poor visibility especially on low beam!.
The headlight output on my new 2014 GMC Sierra is so bad that I cannot drive the vehicle safely at night. In fact, I only drive it unless it is absolutely necessary. Not only are the lights very dim but the shape of the beam is also very poor and awkward . With the current oem headlight equipment, this vehicle is unsafe to operate at night. I contacted the dealer and they told me there was nothing they could do about it . I can't even find a better bulb because gm has the patent and not even piaa can make a better bulb.
Bought vehicle new in March '14, headlights are hid units, and are worse than poor. Very easy to overdrive these lights here on dark, twisty mountain roads in wv. We have the highest rate of vehicle- deer collisions in the us and seeing deer with these lights in time to avoid a collision is chancy. Traded a 10 year old same make and model and never had these problems. These lights need to be corrected before folks are killed as a result.
Headlights are so dim you can not see street signs or the sides of the road clearly.
Vehicle has very poor headlights, making it unsafe to drive at night. Headlights are too dim, and do not provide illumination on shoulders of roadway. Probably the worst headlights I have seen in over 20 years. Dealer says nothing can be done to correct problem. Someone needs to step in and force gm to do something about this issue.
2014 GMC Sierra. Consumer writes in regards to vehicle electrical panel froze while driving. Also, the power steering locked up, the headlights did not work properly and the alarm sometimes sounded after the was removed from the ignition. Also, the engine light illuminated. The vehicle was taken to the dealer twice. However, the problem was still not resolved. There was a hesitation/lurch coming from the transmission, and an issue with the tire pressure monitoring system. The instrument panel malfunctioned on the way back from the dealer. The check engine light, illuminated sporadically. Updated 07/10/14 the consumer stated there was a steering issue, as well. The dealer was unable to replicate the problems. Updated 08/06/14.
The contact owns a 2014 GMC Sierra. The contact stated that the headlights did not project going down a hill and turning on a curve. The vehicle was taken to a dealer, who stated that the headlights were designed that way. The manufacturer was contacted. The approximate failure mileage was 10,000.
This vehicle has the worst headlights of any new vehicle I've ever owned. It seems dangerous to drive at night, and I avoid it where I can. The beam pattern is awful and the illumination is poor. I've been driving cars with projector headlights for years, so I know that is not the real issue. These lights are just poorly designed or cheap. Trips to the dealer are unfruitful. The dealer knows they are poor, but can do nothing except be sure everything is properly adjusted. If you are looking at buying a 2014 GMC pickup, buy something else. They are that bad. I just know I'm going to hit a deer soon enough.
Purchased my 2014 GMC Sierra November of 2013. Currently I'm on my 9th recall notice. More importantly the lighting on my front headlights are the most unsafe lighting at night I have ever encountered. The high beams are use less. Paid $43,000 for my truck. You would think their lighting would be top notch. The bad thing about this is no one has been hurt so GMC isn't expressing any concerns about this major flaw. This should be a major recall were proper lighting is put in. Nothing will be done till someone gets into a accident or dies from injuries from lack of lighting.
The contact owns a 2014 GMC Sierra. The contact stated that while driving after dark, the front halogen headlights became dim. The contact stated that the vehicle was taken to the dealer where it was diagnosed that the front headlights needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 700.
Worst headlight for a new vehicle. I have owned various gm trucks from 1967 to 2014. Never have I owned a truck with such worthless headlights like the projector beam headlights on my 2014 GMC Sierra 1500 with the all terrain package. The projector headlight are very dim and do not light the road more than 30 feet ahead. At highway speeds (55-70) the projector headlights are only lighting a half second ahead of you. Additionally there is no lighting to illuminate the sholder at all. . You must drive full time with the fog lamps on to have a small increase in lighting. When using the high beams there is very little effect on visibility. Extremely disapointed in the 2014 GMC Sierra. And will unlikely purchase another gm product in the future. At a msrp of over 50 grand I would expect a truck to have adequate headlight to light the road. Without the aftermarket cost to install better lighting the 2014 GMC Sierra is very unsafe to operate at night.
Many problems: 4 wheel drive sensor, front end suspension, parking brake, service brakes, anti-lock brakes, speed sensors, radio, center console, engine noise rapping when starting, tailgate cables, anti-theft sensor, and now the battery voltage gauge needle excess dropping when stopping, engine idling to low when stopping. Dealer says problem is normal. Let's test drive a new truck and show me it is normal. This truck is a lemon in my eyes!.

The running lights continued to short out. The bulbs have been replaced eight times in the past year. This did not affect normal use of the headlights or the tail lights. The vehicle has not been to the dealer for this issue. Contacted manufacturer, who said they would not pay for the repairs. The contact believed the lens on the day time running lights were filling up with water when it rained. The contact drilled holes in the bottom of the lens to allow water to escape. Since the contact had performed the drilling the lights have not shorted out as often.
The vehicle headlights are to bright on normal setting, distracting view from on coming traffic. Dealer notified.

While driving at night, consumer pushed dome light over ride button, immediately headlights and dash lights went out. Vehicle was taken to dealer, GMC was contacted. Manufacturer stated this was the design of the vehicle. To press again 4 times within 6 seconds. This would prompt all lights to come on again. There is a section in owners manual where this fact is mentioned, but not in clear terms. Dealer could not fix.
Daytime running lights failed to function during daylight hours. Consumer has examined elements for headlights and found no defect while dealership has not examined vehicle.

I am not sure if this is the correct forum for voicing these concerns but I hope and can be enlightened about these problems. I am not sure of the exact mileage or dates of any of these incidents without further study. The seatbelts on this truck will lock up intermittently while driving down the street with no braking. The right windshield wiper has broken free from the mechanism twice. The daytime lighting does not work though the lamps and fuses are in working condtion. The power steering pump sheared a shaft in two and was replaced under warranty. The engine clatters and was fixed once by the dealer however the fix has never lasted more than half of an oil change(1,500 miles. ) the headlight and rotary dimmer switches and surrounding trim on the dash get extreemely hot to the point of burning. I know I have missed something, it's hard to believe that so many things have gone wrong with this truck.
Headlights flicker on and off rapidly. Dealer thinks alternator is at fault.
I have experienced excessive wearing of the front brakes, which has resulted in the rotors being replaced first, then the pads replaced 2 weeks later, and upon replacing the pads the new rotors required resurfacing. Since then after driving approx 5k miles, I was told that the new pads are appox 40% worn. I required the right front balljoint to be replaced when the rotors were done. When applying the brakes & hitting a bump in the road, the brake pedal goes down to the floor and has a complete lose of braking. It failed the annual inspection, due to a leaking donnut gasket. The tailgate squeaks & rattles, and appears out of alignment. The front driver's door creaks requiring repeated greasing. There appears to be excessive wearing in the front end and braking system, as well as excessive creaking & noise from the rear area of the truck, tailgate, and driver's door. I have been met with continued resistance and lack of answers from both the mfg and dealer. Any help or information would be appreciated.

While driving in snow speedometer started moving back and forth. Then consumer smelled rubber burning, and headlights popped out. Took to dealer and they said something overheated on the outside. But consumer said it was on the inside. Dealer put a module in, and made the problem worse. Consumer fears loosing lights on the road.
Headlights go out when tire spin or when anti-lock brakes are activated.

Dealer charge to replace defective switch was $502. 65. This is a safety problem when headlights fail while driving vehicle at night. Incident could have caused an accident or fire.
