2015 GMC Sierra 1500 Exterior Lighting

Headlights on this vehicle, since purchased, have not cast enough light in order to see in unlit backroads, or extrememly dim areas. I have to drive with my brights on constantly, in order to get enough light thrown onto the road, for the left and right sides, as well as the front. These were not working well since purchase. I took my child to a friends house in rural PA, and I literally could NOT SEE THE street signs, let alone far enough down the road. I nearly hit a stone wall.. My eyes keep asking to see more, but truck does not produce enough headlight. I even went to the eye doctor, after that situation, thinking it was my vision dimming, but was told I have 20/20. There needs to be a formal recall. I am not the only one complaining about these HORRIBLE projection headlights. To replace these headlights would cost over 1000K, out of pocket, which is not something I should have to fix. I am complaining now, because with the light getting darker earlier, am noticing how lousy driving at night really is.. and honestly, being BLINDED by oncoming LED's , without having proper headlights on my truck in order to see when blinded, really [XXX]. Please address these [XXX]. Make headlights great again! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Lack of illumination of headlights straight ahead. No light shines to the sides of the vehicle making it difficult to see left or right when negotiating a turn at night. I have put new bulbs in both sides the best money can buy at CarQuest with no improvement. The headlight lenses are not dirty or fogged over. It appears to be a design problem, and I have seen other people with this model truck complain about the same thing on some blogs. I contacted GM directly looking for information I can get on a possible upgrade, and they have offered not solution. I have had this issue with this vehicle since buying it used 4.28.2018

Headlights are so dim because of the plastic cover that is made into the OEM headlight assembly. The plastic apparently had no UV protectant and the plastic has turned dingey yellow and clouded where it's affected the light output from the vehicle

The stock headlights both low and high beams provide poor lighting at night. The headlights provide a poor beam pattern making it incredibly difficult to see more than 100 ft in front of you while driving down dark roads. And even more difficult in light storm conditions both rain and snow. The high beams aim too high when used and don't show enough of the road in front of you but rather the tops of tree's or other objects instead of the road. The low beams don't provide much light on the sides of the road as well and at times feel more like they're just fog lights with the amount of light that is put out. These incidents happen anywhere from low speeds up to highway speeds. I have noticed this issue since purchasing it used and have seen multiple similar complaints online.

Lights are too dim to drive at night. Bulbs have been replaced with 6 different styles but the lights are too dim. Bright lights shine too high to be useful. Spoke with numerous people who have had the same problem.

This vehicle has poor headlight performance. I changed the bulbs to no avail. There is no way this 2015 GMC passes vehicle state inspections if they really look. There is very little power to the lights, even on the high-beams. After some quick research - GM has a service bulletin PIT5374 that addresses this very issue. But the dealerships are using this safety defect as a way to generate service volume. Requiring a $170.00 diagnosis to identify a problem they already know exists.

THE HEADLAMPS ON MY VEHICLE HAVE BEEN VERY POOR, BOTH IN LOW AND HIGH BEAM POSITIONS EVER SINCE I PURCHASED THE VEHICLE. THINKING THAT THEIR MUST BE SOMETHING WRONG WITH THE EXISTING HEADLAMPS, I PURCHASED THE REPLACEMENT BULBS AND THERE WERE NO IMPROVEMENTS. WHEN DRIVING AT NIGHT I HAVE TO STAY ON LOW BEAM WITH THE FOG LIGHTS ON JUST TO HELP TO SEE. I CAN'T USE MY HIGH BEAMS AT ALL BECAUSE THE LIGHTING IS SO POOR. GMC IS AWARE OF THEIR HEADLAMP ISSUES ON THE 2014 AND 15 MODELS BUT NOTHING IS BEING DONE ABOUT IT TO MY KNOWLEDGE. WITHOUT SPENDING $500-$1000 TO CHANGE THEM OVER TO LED, IS THERE ANYTHING THAT I CAN DO TO IMPROVE THIS SITUATION?

The headlights are very poor. Can hardly see at night. They're no better when on high beams.

THE 3RD BRAKE LIGHT ALLOWED RAIN TO ENTER THE CAB OF TRUCK.(GASKET FAILED) HEADLINER, CARPET ON FLOOR, INSULATION ALL RUINED. DIAGNOSED BY A "WATER DOCTOR" AT THE DEALER WHERE TRUCK WAS PURCHASED. THE FLOOR ON THE PASSENGER FRONT WAS SOAKED, HEADLINER IS STAINED. I REMOVED ALL SEATS, CARPET, INSULATION AND THE SMELL IS STILL THERE. CALLED GMC TO TRY TO GET ASSISTANCE ON REPAIRS. TRUCK IS OUT OF FACTORY WARRANTY. GMC OFFERED $585 LEAVING A BALANCE OF $1300 TO BE PAID BY ME TO REPLACE THE HEADLINER. HOW IS IT THAT THE 3RD BRAKE LIGHT ALLOWS RAIN TO ENTER THE CAB OF THE VEHICLE. ITEMIZED ESTIMATE FROM DEALER TO REPLACE AND PUT TRUCK BACK TOGETHER IS $4500-$5000. MONEY THAT I DON'T HAVE. THIS IS A POOR DESIGN. DID NOT KNOW/REALIZE THAT A GASKET WOULD FAIL AND ALLOW WATER TO LEAK INSIDE. THE TRUCK IS PARKED IN OUR DRIVEWAY OR ON THE STREET. I DO NOT HAVE A GARAGE. I STARTED TAKING THE SEATS AND CARPET OUT THE LAST WEEK OF DECEMBER 2020. OVER THE NEXT FEW WEEKS INSULATION WAS REMOVED. THE MOLDY/MUSTY SMELL REMAINS. GMC WAS CONTACTED APPROXIMATELY THE LAST OF JANUARY OR THE FIRST WEEK OF FEBRUARY 2021. I AM STILL IN TALKS WITH THEM. AARON, CASE MANAGER AT GMC WITH WHOM I HAVE BEEN DEALING. HE IS TRYING TO FIGURE OUT SOMEWAY TO GIVE ME ASSISTANCE IN GETTING MY TRUCK BACK TOGETHER. I DON'T KNOW HOW LONG IT HAS BEEN LEAKING BEFORE I STARTED SMELLING THE MUSTY ODOR.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500. THE CONTACT STATED THAT THE HEADLIGHTS WERE VERY DIM MAKING IT DIFFICULT TO VIEW THE ROAD WHILE DRIVING AT NIGHT. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO VARNEY BUICK GMC MAZDA (260 HOGAN RD, BANGOR, ME 04401) WHERE THE BULBS WERE REPLACED UNDER A TECHNICAL SERVICE BULLETIN HOWEVER, THE BULB REPLACEMENT FAILED TO FIX THE FAILURE. THE CONTACT STATED THAT HE REPLACED THE BULBS TWICE WITH LED BULBS HOWEVER, THE FAILURE PERSISTED. THE VEHICLE WAS NOT TAKEN BACK TO THE DEALER AND WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 28,202. CONSUMER STATED VEHICLE WAS TAKEN TO THE DEALER FOR DEFECTIVE DRIVING LIGHT. DEALER STATED NOTHING COULD BE DONE ABOUT IT. CONSUMER ALSO STATED HE HAD HIT 2 DEERS AT NIGHT.*JB

WHILE THE HEAD LIGHTS AND FOG LIGHTS ARE ON, THE RIGHT HEAD AND FOG LIGHTS ARE DIM BUT THE LEFT HEAD AND FOG LIGHTS ARE BRIGHT. ALSO THE RIGHT TURN SIGNAL SHOWS ERROR MESSAGE ON THE CLUSTER THAT THE BULB NEEDS TO BE REPLACED AND YOU CAN HEAR IT BLINKING FAST, BUT WHEN I EXIT THE VEHICLE TO INSPECT THE SIGNAL I NOTICE THAT IT IS NOT BLOWN AND IT WORKS FINE BUT I STILL GET THE ERROR MESSAGE AND THE FAST BLINKING. BOTH STATED PROBLEMS OCCUR WHILE THE VEHICLE IS STATIONARY AND WHEN THE VEHICLE IS IN MOTION. *TR

TL* THE CONTACT OWNS A 2015 GMC SIERRA. THE CONTACT STATED THAT WHILE DRIVING AT NIGHT OR IN INCLEMENT WEATHER, THE HEADLAMPS LUMINESCENCE WAS NOT ADEQUATE FOR SAFE DRIVING. THE CONTACT STATED THAT THE HEADLAMPS WERE EXTREMELY DIM. THE CONTACT STATED THAT HE PULLED OFF OF THE ROADWAY SEVERAL TIMES DUE TO THE HEADLAMP FAILURE. THE VEHICLE WAS TAKEN TO LONE STAR CHEVROLET (18900 NORTHWEST FREEWAY, HOUSTON, TX 770650, AND WAS DIAGNOSED. THE CONTACT WAS INFORMED THAT THE VEHICLE OPERATED AS INTENDED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE CONTACT WAS THEN INFORMED THAT THE VEHICLE WAS OUTSIDE OF THE 36,000 MILE WARRANTY. THE FAILURE MILEAGE WAS 106,000.

BOTH BACK BRAKE LIGHT WORK INCONSISTANTLY. WHILE MOVING AND AT A COMPLETE STOP. LOCAL DEALERSHIP CHARGES AT MIN 1200 PER LIGHT TO FIX. SEEMS TO BE A COMMON PROBLEM WITH THE DENALI'S.

2015 GMC SIERRA SLE / 60K MILES / PROJECTOR HEADLIGHTS...NUMEROUS COMPLAINTS FROM NUMEROUS OTHERS, I'M IN THE SAME BOAT. ILLUMINATION IN GENERAL, DRIVING IN RURAL AREAS, DRIVING IN INCLEMENT WEATHER, MAKING TURNS (SIDE STREETS), ETC., IS HORRIBLE, UNSAFE, NERVE-RACKING AND TROUBLESOME. SURE, THE HEADLIGHTS LOOK SNAZZY, BUT PERFORM ABOUT AS WELL AS MY LAWN TRACTOR'S HEADLIGHTS. I SEE THERE'S A TSB REGARDING THE SITUATION AND, MUCH TO MY DISMAY, I HAVE TO PAY FOR SAID PARTS/LABOR TO CORRECT AN OBVIOUS DESIGN FLAW/SNAFU. AM I CRAZY FOR THINKING THIS IS UNACCEPTABLE? EVEN MORE SHOCKING, IT APPEARS THE BCM REPROGRAMMING (MARGINAL RESULTS) AND LAMP REPLACEMENT IS PROBLEMATIC (INCREASED VOLTAGE TO A BULB/LAMP SHORTENS ITS LIFE CONSIDERABLY). A VEHICLE THAT COSTS 30-40-50K SHOULD NOT HAVE GARBAGE TECHNOLOGY. ON THE PLUS SIDE, AT 48 YEARS YOUNG, MY VISION REMAINS 20/20 AND I DO NOT REQUIRE VISION CORRECTION. THE WIFE, MY 2 KIDS (OF DRIVING AGE) AND MY NEIGHBOR CONCUR - THESE HEADLIGHTS SUCK. I LOVE EVERYTHING ELSE ABOUT THE VEHICLE, BUT IT LOOKS LIKE INSTEAD OF SPENDING $200 FOR THE TSB, I'LL TRY MY LUCK WITH AFTERMARKET REPLACEMENTS FOR $300. VIA MULTIPLE ONLINE VEHICLE FORUMS, MOST WHO'VE GONE THE ROUTE OF TSB ARE MARGINALLY IMPRESSED AND EVERYONE ELECTING TO GO WITH AFTERMARKET IS COMPLETELY SATISFIED...THAT ALONE SHINES A SPOTLIGHT ON THE LACK OF VISIBILITY BOTH THE NHTSA AND GM ARE PROVIDING THE CONSUMER. MAYBE INSTEAD OF PAYING SUITS MILLIONS PER YEAR TO PRODUCE SUBPAR VEHICLES, GM SHOULD DO THE RIGHT THING AND FOCUS ON WHAT MATTERS MOST -- THE PAYING CUSTOMER. YEAH, WE HAVE A BETTER SHOT WITH THE NHTSA HOLDING GM ACCOUNTABLE AND FORCE THEM INTO A RECALL (CORRECTING THE PROBLEM PROPERLY, NOT A WILLY NILLY REPROGRAM AND BULB REPLACEMENT).

VERY POOR HEADLIGHTS. I JUST CAN'T SEE. IT IS LIKE A FOG. NLOCKED OUT SIDE VIEWS. DIMS ARE NOT GOOD AND BRIGHTS DON'T EVEN GET FLASHED BY ONCOMING VEHICLES. THEY SHINE IN THE TREES. I TOOK THE VEHICLE IN THREE TIMES TO A DEALER OF GMC'S AND THEY DON'T HAVE A SOLUTION. THEY SAID THEY REALIZE THE PROBLEM BUT HANDS ARE TIED BECAUSE I THINK IF THEY START TO FIX IT A CAN OF WORMS WILL BE OPENED UP AND COST THE COMPANY. HOW MANY COMPLAINTS MUST YOU HAVE?

HEADLIGHTS ARE POOR. LOW AND HIGH BEAMS DO NOT ILLUMINATE THE ROAD EFFECTIVELY IN RURAL AREAS

BOTH BREAKLIGHTS NO LONGER WORK DUE TO FAULTY ELECTRICAL PANEL.

PROJECTOR STYLE HEADLIGHTS THAT CAME FACTORY ARE TOO DIM MAKING IT VERY DIFFICULT TO DRIVE AT NIGHT AND UNSAFE. LIGHTS ARE NOW POWERFUL ENOUGH TO LIGHT UP THE ROAD.

WE BOUGHT OUR 2015 DENALI 1 YEAR AGO AND HAVE APPROX 50,000 MILES AND THE PASSENGERS SIDE TAIL LIGHT IS OUT. AFTER RESEARCHING TAILLIGHT PROBLEMS FOR MY MAKE AND MODEL THIS SEEMS TO BE A VERY COMMON ISSUE. THIS SHOULD BE CONSIDERED AS A RECALL BUT WHEN LOOKED INTO, I SEE IT IS NOT. ITS A SHAME TO SPEND SO MUCH MONEY ON A VEHICLE TO HAVE THE TAIL LIGHT OUT AT 3 YEARS (AFTER FACTORY WARRANTY IS ALREADY OUT) AND YOU HAVE TO REPLACE THE WHOLE TAIL LIGHT INSTEAD OF ONE PIECE.

THE STOCK FACTORY HEAD LAMPS/BULBS ARE VERY DIM AND DO NOT LIGHT UP THE SIDE OF THE ROAD OR VERY FAR DOWN THE ROAD AND THE LIGHTS HAVE A VERY SHARP CUT OFF LINE.

RIGHT BRAKE LIGHT IS OUT

HEADLIGHTS ARE VERY DIM, HARD TO SEE AT NIGHT ESPECIALLY WHEN IT IS RAINING. MUST USE FOG LAMPS AT ALL TIMES TO BE ABLE TO IMPROVE VISION. CONTACTED GM AND DEALER ABOUT ISSUE, HAVE CLAIM NUMBER. THEY SAY TRUCK IS NO LONGER UNDER WARRANTY TO DO ANYTHING.

THE HEADLIGHTS ON MY 2015 GMC SERRIA 1500 SLT ARE UNSAFE. THE HEADLIGHTS DO NOT LIGHT TO THE SIDES ADEQUITELY AND THIS IS VERY APPARENT WHEN MAKING A TURN AT NIGHT. I HAVE ALSO READ ABOUT THIS SAME HEADLIGHT SAFETY CONCERN ON SEVERAL WEBSITES POSTED BY OTHER OWNERS.

NIGHT TIME VISION IS COMPROMISED DUE TO POOR HEADLIGHT ILLUMINATION, MOST NOTABLE IN AREAS OF LOW AMBIENT LIGHTING OR RAIN. THIS HAS BEEN PRESENT SINCE PURCHASED NEW. TRUCK HEADLIGHT BULBS WERE UPDATED UNDER GENERAL MOTORS SERVICE BULLETIN PIT5374B AT LOCAL GMC DEALER WHERE VEHICLE WAS PURCHASED. CHARGE FOR THIS UPDATE WAS $149.21. WHILE I DO NOT HOLD THE DEALER RESPONSIBLE FOR THIS CHARGE, I DO FEEL THE SUBSTANDARD LIGHTS SHOULD BE CONSIDERED A MANDATORY SAFETY ISSUE AND DEALT WITH AS SUCH

HEADLIGHT QUALITY HEADLIGHT QUALITY IS VERY POOR,SIDE LIGHTING AND DISTANCE LIGHTING ARE TERRIBLE. GM ISSUED A TSB BUT NO RECALL FOR PEOPLE WHO COMPLAINED ABOUT THE HEADLIGHTS.I PURCHASED AT 37K SO AM BEYOND THE 3YR/36K. I AM LOOKING INTO AFTER MARKET FIXES FOR THE PROBLEM. I WAS TOLD THE PROBLEM WAS FIXED IN THE 2016 MODELS.
