EXTERIOR LIGHTING
HEADLIGHT ON THIS TRUCK ARE EXTREMELY HORRIBLE AND UNSAFE AT NIGHT TIME. THE LIGHT OUTPUT IS WORST THEN ANY OTHER VEHICLE I HAVE EVER DROVE. GM NEEDS TO STAND BEHIND THE ISSUE AND PROVIDE A SOLUTION
NHTSA complaint #11297243 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
THE HEADLIGHTS ON MY NEW GMC SIERRA 2500HD DENALI ARE HORRIBLE AND UNSAFE FOR DRIVING AT NIGHT. THE 25 WATT RATING AND 2,000 LUMENS ON THE OEM HID BULBS DO NOT PROVIDE ADEQUATE, SAFE LIGHTING FOR OPERATING MY VEHICLE. I ALREADY HIT A DEER WITH MY BRAND NEW TRUCK BECAUSE I COULDN'T SEE IT WELL ENOUGH IN ADVANCE OF THE COLLISION. GMC SHOULD BE HELD ACCOUNTABLE FOR PUTTING SUCH A LOW POWER, POOR QUALITY AND UNSAFE HEADLIGHT IN THEIR $70,000 VEHICLES. I'M RENTING A HYUNDAI WHILE MY TRUCK IS BEING REPAIRED AND THE HEADLIGHTS ON THIS $30,000 FOREIGN CAR ARE 10XS BETTER THAN THE ONES ON MY TRUCK. WHY?
NHTSA complaint #11056076 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
THE PROJECTOR HEADLIGHTS ARE INADEQUATE ON A LEVEL ROAD, AND ARE DANGEROUS ON ROLLING TERRAIN ROADS AND CURVES. THEY COULD BE POSSIBLY DESIGNED FOR STATIONARY USE IN A PERFECT ENVIORMENT BUT NOT FOR MOVING VEHICLES, I CANNOT SAFELY DRIVE THIS VEHICLE AT NIGHT, I FEAR NOT ONLY FOR MYSELF BUT FOR OTHER PEOPLE ON AND NEAR THE PATH OF THIS VEHICLE. MY MIND IS CLEAR, THERE ARE MANY BLOWING THE WHISTLE.
NHTSA complaint #10860170 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
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.
NHTSA complaint #10855440 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
TL* THE CONTACT OWNS A 2015 GMC SIERRA. THE CONTACT STATED THAT THE LOW BEAM HEADLIGHT WAS DEFECTIVE AND DID NOT PROVIDE ADEQUATE LIGHT COVERAGE. THE CONTACT HAD TO ENGAGE THE HIGH BEAMS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE DEALER RAISED THE LOW BEAMS; HOWEVER; THE LIGHT COVERAGE WAS NOT CORRECTED. THE FAILURE MILEAGE WAS 300. ..UPDATED 05/09/16 *BF THE CONSUMER STATED RIGHT AFTER HE PURCHASED THE VEHICLE, HE NOTICED WHEN DRIVING AT NIGHT, WITH THE LOW BEAMS ON, HIS VISIBILITY WAS APPROXIMATELY 30 FEET TO THE FRONT AND SIDE OF THE VEHICLE. WHEN THE HIGH BEAMS WERE ON, HE WAS ABLE TO SEE AHEAD OF HIM, BUT THE VIEW WAS STILL LIMITED TO ONLY 30 FEET. UPDATED 05/16/16.
NHTSA complaint #10854991 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
HEADLIGHTS ARE FAR TO DIM AND DIRECTIONAL TO DRIVE SAFELY AT NIGHT. HAD THE LIGHT FIX DONE AT DEALER. NOW HORIZONTAL BLACK LINE GOING DOWN HILL MEAN YOU CAN ONLY SEE A VERY SHORT DISTANCE IN FRONT OF YOU? HEADLIGHTS STILL INADEQUATE .
NHTSA complaint #10853135 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
THE HEADLIGHTS ARE VERY DIM AND MAKE IT HARD TO SEE AT NIGHT. I HAVE HAD SEVERAL SITUATIONS WHERE AN ACCIDENT WAS MORE LIKELY DUE TO THE DIM LIGHTING.
NHTSA complaint #10853032 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
HEADLIGHT PERFORMANCE IS VERY POOR WITH WEAK YELLOW BEAM BOTH ON LOW AND HIGH BEAMS. DIFFICULTY SEEING DURING NIGHT DRIVING, ESPECIALLY AT HIGHWAY SPEEDS IN DARK AREAS, IS VERY HAZARDOUS, EVEN WORSE DURING RAIN. I AM CONCERNED ABOUT MY SAFETY AND THAT OF MY FAMILY WHILE DRIVING THIS TRUCK AT NIGHT. THE PROJECTOR-STYLE HEADLAMPS ON THE VEHICLE WERE DIM WITH A YELLOW COLOR AND PROVIDED INADEQUATE FRONT AND SIDE ILLUMINATION. THE HEADLIGHT AIM WAS RAISED, WHICH RESULTED IN LITTLE IMPROVEMENT.
NHTSA complaint #10850161 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
PROJECTOR HEADLIGHTS ON 2015 SIERRA IS VERY DIM COMPARED TO OTHER VEHICLES. TRIED ADJUSTING BUT DID NOT HELP. VERY POOR VISIBILITY IN UNLIT DARK ROADS AND STREETS AND POSES RISK. I TRIED BRINGING IT TO THE DEALER BUT THEY COULD NOT DO ANYTHING ABOUT IT. I MENTIONED SEVERAL COMPLAINTS FROM OTHER OWNERS INCLUDING A CLASS ACTION LAW SUITE THAT WAS FILED IN CALIFORNIA IN OCTOBER 2015. UNFORTUNATELY, THERE ARE NO OTHER ALTERNATIVES WITH THE EXCEPTION OF PURCHASING AFTERMARKET HEADLIGHTS. I WOULD LIKE GMC TO FIX THIS KNOWN PROBLEM. APPARENTLY THEY DID AS THEY CHANGED THE 2016 MODELS' HEADLAMPS AND INCORPORATED HIGHER LUMENS ON LIGHTING, WHY CHANGE IT IF IT WAS NOT A PROBLEM IN THE FIRST PLACE? IT'S VERY DIFFICULT TO SEE PEDESTRIANS AND OBJECTS AT NIGHT.
NHTSA complaint #10850003 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
I PURCHASED THIS VEHICLE NEW AUGUST 2015. THE HEADLIGHT PROJECTION AND ILLUMINATION ON THIS VEHICLE IS EXTREMELY POOR ESPECIALLY DURING WET ROADS OR RAINING CONDITIONS. I HAVE TO USE THE FOG LIGHTS AT ALL TIMES AND STILL DO NOT HAVE ADEQUATE LIGHTING. I FEEL THIS SITUATION CAN AND WILL RESULT IN SERIOUS INJURY OR DEATH DUE TO LACK OF PROPER LIGHTING. I WAS APPALLED TO FIND OUT GENERAL MOTORS ONLY USE A SINGLE HALOGEN BULB INSTEAD OF A DUAL FILAMENT LAMP OR A COMBINATION LOW AND HIGH BEAM LAMPS. I PERSONALLY NEARLY HIT A PEDESTRIAN DURING A RAINY SITUATION, AND ALSO FEEL UNSAFE OPERATING THIS VEHICLE AT DARK.
NHTSA complaint #10849881 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
HEADLIGHT DESIGN IS TERRIBLE. I GET AT BEST 40FT. OF LIGHT PROJECTION ON LOW. WHEN THE HIGH BEAMS ARE ENGAGED I GET NO FURTHER PROJECTION BUT I GET A HIGHER PROJECTION. IT DOES A GREAT JOB LIGHTING THE TOPS OF THE TREES BUT THAT'S ABOUT ALL. UNBELIEVABLE SAFETY HAZARD WHILE DRIVING IN RURAL SOUTHWEST FLORIDA.

EXTERIOR LIGHTING
CAN NOT SEE THE ROAD WITH THE LIGHT OUTPUT WITH THESE FACTORY HEADLIGHT
NHTSA complaint #10845655 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
TL* THE CONTACT OWNS A 2015 GMC SIERRA. WHILE DRIVING AT NIGHT, THE LOW BEAM HEADLIGHTS FAILED TO ILLUMINATE SUFFICIENTLY. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 7,500.
NHTSA complaint #10840233 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
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.
NHTSA complaint #10840105 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
THE LOW BEAMS ONLY ILLUMINATE 40 TO 50 FEET DOWN THE ROAD. THE HIGH BEAMS PROVIDE VERY POOR VISIBILITY. THERE IS ABSOLUTELY NO SIDE ILLUMINATION. THIS IS A CHALLENGING VEHICLE TO DRIVE AT NIGHT.
NHTSA complaint #10840159 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
THE HEADLIGHTS WITH WHICH THIS VEHICLE ARE EQUIPPED ARE DIM AND UNSAFE. I HAVE OWNED MANY VEHICLES, INCLUDING SEVERAL MADE BY GM, AND THIS ONE IS THE WORST. THE ILLUMINATION OF THE ROADWAY IS INSUFFICIENT TO DISCERN HAZARDS ON/NEAR THE ROADWAY AT NIGHT. THIS IS TRUE AT ANY REASONABLE SPEED AND IS MUCH, MUC HWORSE DURING INCLEMENT WX, PARTICULARLY WHEN RAINING.
NHTSA complaint #10837652 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
THE STEERING COLUMN IS LOOSE! THIS IS A PROBLEM THAT IS TALKED ABOUT ON THE INTERNET. THE HIGH BEAM SWITCH HAS FAILED. THE SWITCH IS LOCATED IN THE STEERING COLUMN AND ITS FAILURE MAY BE RELATED TO THE LOOSENESS. GMC SHOULD REPAIR THESE SAFETY PROBLEMS ON MY VEHICLE WITHOUT CHARGE.
NHTSA complaint #10837875 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
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.
NHTSA complaint #10837340 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
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.
NHTSA complaint #10826029 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
HEADLIGHTS ARE NOT ADEQUATE FOR SUBURBAN OR RURAL AREAS. INADEQUATE SIDE-TO-SIDE ILLUMINATION IN HI OR LOW. DEALER IS UNABLE TO FIX.
