2014 GMC Sierra: headlights failing or too dim

Filed Apr 14, 2016 · Lights · 9 miles · GA

The vehicle lights are very dim even with the high beams on. While driving at night can barely see in front of me. These are a hazard to me and others, since not being able to see a good distance in front of the vehicle makes hard to see pedestrians, animals or debris in the road at night.

Can not see the road with the light output with these factory headlight

The headlights are too dim and are unsafe. In my 50+ years of driving, I have never experienced headlights so bad. I live in a dark rural area without any streetlights and lots of bicyclists and deer. I have already had many near misses on rural roads, and fear it's only a matter of time before an accident happens.

The headlight output at night, particularly in rural back road areas is less than adequate. Poor really. I originally had moisture issues in both headlamp housings, had both headlamp housings replaced and the lighting seemed to be better, however not very much. The headlights seem to have dark spots in them and only light up certain parts of the road in front of me, and never much to the side of the roadway. I feel this is by far the worst lighting output of any vehicle I have ever owned, and actually feel a little unsafe driving at night. I most definitely cannot travel at higher speeds during the night as I feel like I cannot see nearly good enough. I have simply "dealt" with the issue since buying the truck in december 2013, thinking there was no fix to it and the dealership said they have not heard of this issue before.

Headlights are not adequate for suburban or rural areas. Inadequate side-to-side illumination in hi or low. Dealer is unable to fix.

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 federal safety agency 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.)

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 front projector headlamps do not put out enough light to safely drive on unlit roads at highway speeds. There is also little light projected to the side making turns unlit. I recently had a near hit with a pedestrian on an unlit street because of no side lighting when making a slow turn. There are no higher lumen replacement bulbs available.

2014 gmc sierra. Consumer writes in regards to vehicle headlight problems. *smd the consumer stated when he made turns, there was not sufficient lighting. The dealer stated the head lights were four inches too high, so they adjusted them. Upon driving at night, he found the lighting to the side had slightly improved, but the light was sharply cut off about 45 feet in front of the truck on when the low beams were on, which made it unsafe to drive over 35 MPH. The high beams gave good lighting at distances, but brought flashed from oncoming traffic. The second head light adjustment extended the lighting out about 20 inches further, but less lighting to the sides for turning. The head lights were adjusted again and the technician stated the lights were at the level from the factory. The consumer stated the head lights were not adequate in his opinion.

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 .
