2014 GMC Sierra Lighting Problems

THERE IS ALREADY A TECHNICAL SERVICE BULLETIN ON THIS MATTER HOWEVER I FEEL IT IS SERIOUS ENOUGH TO BE A RECALL. WHILE DRIVING AT NIGHT IN UNLIGHTED AREAS THE BRIGHT LIGHTS LEAVE SERIOUS DARK AREAS ESPECIALLY IF YOU ARE TRAVELLING ON CURVY ROADS. IF YOU ENCOUNTER A PEDESTRIAN OR OTHER OBJECT IN THE ROAD IN THESE AREAS THEY CANNOT BE SEEN UNTIL ITS POSSIBLY TOO LATE. THE MANUFACTURER WILL ONLY DO THE REPAIR IF YOU COMPLAIN ABOUT IT AND ITS STILL UNDER WARRANTY. I BELIEVE THIS SHOULD BE RECALLED AND REPAIRED BEFORE SOMEONE IS HURT OR KILLED.

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.

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 .

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 NHTSA 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.)

HEADLAMPS DO NOT ADEQUATELY LIGHT UP ROAD. VERY UNSAFE. DEALER WON'T HELP. *TR

HEADLIGHT OUTPUT IS HORRIBLE AT NIGHT TIME DRIVING ON THE HIGHWAY. IT IS FLAT OUT DANGEROUS. THE HEADLIGHTS ARE ONLY ADEQUATE FOR CITY DRIVING AT NIGHT. *TR

I WISH TO COMPLAIN ABOUT THE HEADLIGHTS ON THIS VEHICLE. THEY ARE REALLY TERRIBLE. LOW BEAM DOES NOT PROJECT FAR ENOUGH, AND HIGH BEAM SEEMS TO ILLUMINATE ROAD SIGNS AT A DISTANCE, BUT NOT ADEQUATE FOR THEIR PURPOSE. SEEMS AS THEY ARE MORE OF A SPOTLIGHT THAN A HEADLIGHT. THESE ARE THE MOST UNSAFE HEADLIGHTS I HAVE EVER HAD IN 43 YEARS OF DRIVING. AGAIN, THERE WAS NO ACCIDENT THANKFULLY, AND I JUST WISH TO FILE MY COMPLAINT AND CONCERN. THANK YOU. *TR

THIS IS MY FIRST TIME TO HAVE A VEHICLE WITH PROJECTOR HEADLIGHTS. THEY DO NOT LIGHT UP THE SIDES OF ROAD, AND ARE NOT VERY BRIGHT IN DIM OR HIGH BEAM. THIS IS NOT VERY SAFE WHEN DRIVING AT NIGHT, EVEN WHEN THE WEATHER IS GOOD. I WILL NOT BUY ANOTHER VEHICLE WITH THESE TYPE OF HEADLIGHTS. *TR

HEADLIGHTS ARE VERY DIM. LIKE HAVING NONE AT ALL. HIGH BEAMS ARE USELESS. I ACTUALLY HAD TO FOLLOW OTHER VEHICLES LIGHTS TO KEEP FROM RUNNING OFF THE ROAD. *TR

I HAVE TWO 2014 GMC SIERRAS WITH VERY WEAK HEADLIGHTS. CALLED GM AND THEY SAID NOBODY HAS COMPLAINED. THEY LIED. WAKE UP GM AND SMELL THE ROSES BEFORE SOMEONE IS HURT OR KILLED. THE HEADLIGHTS LOOK GREAT BUT WORK BAD. FEEL LIKE IT WILL BE FOREVER BEFORE THEY DO ANYTHING SO I ADDED MY OWN AUX. LIGHTS. MY I CAN SEE AGAIN. SPENT 400.00 DOLLARS ON 45,000 DOLLAR TRUCK SO I CAN DRIVE SAFETY AT NIGHT. 2014 CHEVYS HAVE DUEL HEADLIGHTS. MUST BE BETTER. FIX THE PROBLEM GM. MY FIRST CAR, A 1962 COMET HAD BETTER LIGHTS.

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. *JB

TL*THE CONTACT OWNS A 2014 GMC SIERRA. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE HEADLIGHTS WERE VERY DIM AND IMPAIRED THE VISION TO SEE THE ROAD. THE FAILURE RECURRED ON NUMEROUS OCCASIONS. THE VEHICLE HAD NOT BEEN DIAGNOSED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 58. UPDATED 04/13/15*LJ THE CONSUMER STATED THE VEHICLE WAS REPAIRED ACCORDING TO BULLETIN PIT5374. THIS REQUIRED A BULB REPLACEMENT AND BCM REFLASH. UPDATED 10/30/2015 *JS

THE HEADLIGHTS ARE VERY POOR. I HAVE OWNED MANY CARS AND THE LACK OF NIGHT VISION WITH THE 2014 SIERRA IS THE WORST OF ANY CAR I HAVE EVER DRIVEN. I USED TO WORK ON MY FAMILY FARM BACK IN THE 1980S AND OUR OLD TRACTORS AND COMBINES HAD BETTER NIGHT VISIBILITY THAN MY BRAND NEW SIERRA. GMC, YOU MUST FIX THIS NOW! I GUARANTEE YOU WILL HAVE A MAJOR LAWSUIT ON YOUR HANDS IF YOU DON'T. THIS IS SUCH A SIMPLE THING TO GET RIGHT, DO THE RIGHT THING AND RECALL ALL THESE VEHICLES AND INSTALL PROPER HEADLIGHTS. *TR

HEADLIGHTS ON HIGH BEAM WERE AIMED TO HIGH & POINTED UP INTO THE TREES. LOW BEAMS SEEMED OK. I FINALLY TOOK TO A LOCAL DEALER FOR SOME RECALLS AND TALKED TO THEM ABOUT COMPLAINTS AND THEY ADJUSTED SAYING THE LIGHTS WERE AIMED TO HIGH. DROVE VEHICLE YESTERDAY AND THE LOW BEAMS NOW HAVE SO LITTLE PROJECTION FORWARD THAT I'M AFRAID AT NIGHT, IF ANYTHING CAME IN FRONT OF ME, I'D HIT IT BEFORE BEING ABLE TO STOP. WILL BE TAKING IT BACK TO HAVE LIGHTS ADJUSTED UP AGAIN AND LIVE WITH IT UNTIL GMC DOES SOMETHING. REASON IT HAS TAKEN SO LONG TO FILE COMPLAINT IS I DO NOT DRIVE MUCH AT NIGHTS AND DID NOT THINK OF FILING COMPLAINT UNTIL I FOUND THIS WEBSITE AND READING OTHER OWNERS HAVING THE SAME PROBLEM. *TR

WANTED TO UPDATE INFO ON THIS COMPLAINT. I HAVE BEEN IN CONTACT W/DEALER AND THEY HAVE AGREED TO REPLACE BOTH HEADLIGHTS, EVEN THOUGH THEY CONSIDER THIS TO BE ABNORMAL, WITH THE AGREEMENT THAT IF IT HAPPENS ON NEW HEADLIGHTS THEY WILL CONSIDER IT NORMAL AND DO NOTHING MORE! I FEEL THIS IS A SAFETY ISSUE AS IT OBSCURES THE LIGHT AND ALSO THAT THEY ARE TRYING TO BULLY ME INTO AN AGREEMENT I DON'T AGREE WITH. MY VEHICLE HAS A BUMPER TO BUMPER WARRANTY AND THEY ARE TRYING TO EXCLUDE THIS ISSUE IN THE FUTURE IF I AGREE TO HAVE THE HEADLIGHTS REPLACED NOW. I HAVE CONTACTED GMC REGARDING THIS AND HAVE YET TO HEAR BACK FROM THEM. *TR

HEADLIGHTS APPEARED TO BE LEAKING, CONDENSATION AND WATER DROPLETS. TOOK TO DEALER FOR OIL CHANGE AND ADVISED THEM OF THE HEADLIGHT ISSUE. WAS TOLD THEY WERE NOT LEAKING THAT THE DESIGN OF HEADLIGHTS CAUSED THIS, BULBS BURN SO HOT THEY HAVE A VENT FOR COOLING. BECAUSE OF THE AIR FLOW THROUGH VENT IT BRINGS IN CONDENSATION & WATER DROPLETS CAN FORM WHICH CAN TAKE 2 TO 6 HOURS TO CLEAR! WAS TOLD THAT THEY W/ONLY REPLACE HEADLIGHT ASSEMBLY, WHICH COSTS $900, IF ITS OVER 50% OF THE LENS. I WAS TOLD ONE HEADLIGHT WAS OVER 50% AND HAD WATER DROPLETS, AS WELL AS A HALO EFFECT AROUND THE BULB THAT HE HAD NEVER SEEN BEFORE. HOWEVER, DEALER DID NOTHING AT THE TIME AS THE LENS WAS CLEARING UP. I ASKED ABOUT THE CONDENSATION OBSCURING THE LIGHT OUTPUT AND THEREFORE MY VISION AND WAS TOLD IT WOULD NOT AFFECT IT. AFTER READING THE OTHER COMPLAINTS REGARDING THE HEADLIGHTS I FEEL THIS MAY BE PART OF THE PROBLEM. IF THE LENS IS COVERED INSIDE W/CONDENSATION & WATER DROPLETS, IT DOES AFFECT THE LIGHT OUTPUT. I LIVE IN THE PACIFIC NW WHERE IT RAINS 9 MONTHS OUT OF THE YEAR AND THEREFORE WE HAVE MOISTURE IN THE AIR ALL THE TIME! I AM NOW DOCUMENTING THE CONDENSATION W/PICTURES OF THE HEADLIGHTS EVERY TIME I DRIVE IT...UPDATED 12/30/14*BF THE CONSUMER STATED THE CONDENSATION WAS IN THE FORM OF FOG. UPDATED 01/12/15

POOR LIGHTING WITH HEADLIGHTS. CAN BARELY SEE WHAT IS AHEAD AT NIGHT. SEEMS LIKE THIS COULD BE VERY DANGEROUS, AND I FEEL UNSAFE DRIVING AT NIGHT, ESPECIALLY IN THE RAIN. TURNING ON FOG LIGHTS HELPS A LITTLE, BUT YOU SHOULDN'T HAVE TO CONSTANTLY RUN THEM. BRIGHT LIGHTS DON'T HELP MUCH EITHER. *TR

THE HIGHLIGHTS ON THE 2014 SIERRA SLE ARE A HAZARD TO TRY TO DRIVE WITH AT NIGHT ONLY LIGHT UP 30-40 FEET IN FRONT OF THE VEHICLE I GET MORE LIGHT FROM THE FOG LAMPS TO SEE BY
