2015 GMC SIERRA 2500 Exterior Lighting Problems

Headlights were about as bright as a candle while using high beams changed the bulbs and used a head light restoration kit and within a week headlight lenses were hazed over again high beams are no brighter than low beams

THE HEADLIGHTS ARE COMPLETELY INADEQUATE. IF YOU ARE TAKING A TURN AT NIGHT, THE LIGHTS CONTINUE TO STAY STRAIGHT WITH THE DIRECTION OF THE VEHICLE INSTEAD OF FOLLOWING THE VEHICLE SO THAT YOU END UP TAKING A TURN BLINDLY AND CANNOT SEE THE CURB OR EDGE OF THE ROAD. IT IS A TOTALLY UNSAFE SITUATION. WE HAVE FOUND THAT YOU MAY HAVE A BIT MORE VISIBILITY IF YOU RUN WITH THE FOG LIGHTS ON, BUT VERY LITTLE IMPROVEMENT. PLEASE FIND A SOLUTION, ADDITIONAL HEADLIGHT, AS THIS TRUCK IS VERY SCARY TO DRIVE AT NIGHT.

THE PROJECTOR HEADLIGHTS THAT ARE INSTALLED IN THIS VEHICLE FROM THE FACTORY DO NOT PROVIDE ADEQUATE VISIBILITY AT NIGHT. I AM UNABLE TO SEE MORE THAT 15 FEET IN FRONT OF THIS VEHICLE FROM A SAFETY PERSPECTIVE. I HAVE RETURNED THE VEHICLE TO THE DEALER MULTIPLE TIMES FOR REPAIR. THEY CHANGED THE BULBS BUT STATED THEY ARE WORKING WITHIN DESIGN SPECIFICATIONS AND SAID THAT GM HAD USED A NEW TYPE OF LIGHTING SYSTEM IN 2015 BUT REALIZED IT IS WAS NOT ADEQUATE AND REDESIGNED IN LATER MODEL YEAR. IF GM REALIZES THEY HAVE A PROBLEM WHY WILL THEY NOT REPAIR VEHICLES THAT THEY SOLD PRIOR TO REALIZING THEIR MISTAKE? IN THE RAIN AT NIGHT THERE IS VIRTUALLY ZERO VISIBILITY. GM NEEDS TO FIX THIS PROBLEM AS IT IS A MAJOR SAFETY ISSUE.

RIGHT REAR TURN SIGNAL BOTTOM SOCKET HEATS UP AND CAUSES AN OPEN TO THE TOP TURN SIGNAL SOCKET SO THE TOP TURN SIGNAL QUITS WORKING AND CAUSES THE SYSTEM TO HYPER FLASH.AND INDICATE INOPERATIVE RIGHT REAR TURN SIGNAL IN MESSAGE CENTER. ONLY REPAIR IS TO REPLACE WIRING HARNESS AND SOCKETS. SYSTEM WORKS FINE IN COLD TEMPERATURES AS THE SOCKET DOES NOT HEAT UP ENOUGH. HAPPENS WITH VEHICLE STATIONARY AND IN MOTION. CONTACTED GM ABOUT IT AND GOT NOWHERE.

THE HEADLIGHTS ARE SO DIM THE TRUCK IS DANGEROUS TO DRIVE AT NIGHT. I DROVE IN A SNOW STORM LAST NIGHT AND I COULDN'T SEE AHEAD OF ME. I WAS DRIVING ON A HIGHWAY AT 45MPH.

THE HEADLIGHTS ARE TO DIM AND UNSAFE ON DARK MOUNTAIN ROADS SINCE NEW.

HEAD LIGHTS ARE SO POOR WHEN DRIVING IN RURAL AREAS AND POORLY LIT AREAS THAT THE LATERAL LIGHTING IS SO POOR THAT YOU ARE LEFT TO GUESSING WHERE AND WHAT YOU ARE TURNING INTO, EXTREMELY DANGEROUS TO ALL, DEALER WHERE PURCHASED NEW STATS THERE IS NO FIX, ACCIDENT WAITING TO HAPPEN.

Mileage: 500

THE HEADLIGHTS ARE UNBELIEVABLY INEFFICIENT. THEY LIGHT A NARROW PATH ABOUT 30 YARDS IN FRONT OF THE TRUCK. DRIVING AT NIGHT IS SCARY ESPECIALLY IN THE RAIN.

DROVE OFF THE ROAD BECAUSE THERE WAS VIRTUALLY NO VISIBILITY IN A DARK SUBDIVISION. GMC INITIALLY DENIED THERE WAS A PROBLEM WITH THE POOR HEADLIGHTS --I STOPPED DRIVING THE VEHICLE AT NIGHT SINCE THE $60,000.00 DENALI TRUCK WAS UNSAFE TO DRIVE IN THE DARK!!GMC EVENTUALLY SAID THEY HAD A "BULLETIN" ON THE PROBLEM AND THEY REPLACED THE BULB AND RECALIBRATED THE LIGHTS. ABOUT A 15-20% IMPROVEMENT--I STILL WILL NOT DRIVE THE TRUCK AT NIGHT AS IT IS STILL UNSAFE.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 2500. THE CONTACT STATED THAT THE HEADLIGHTS WERE EXTREMELY DIM AND PREVENTED THE CONTACT FROM VIEWING THE ROAD WHILE DRIVING AT NIGHT. THE CONTACT WAS CONCERNED THAT A CRASH COULD OCCUR. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS SERVICED FOR A MANUFACTURER UPDATE RELATED TO THE HEADLIGHTS; HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN. ...UPDATED 12/28/16 *BF THE CONSUMER STATED THE LIGHTS ARE OK. HOWEVER, THEY COULD BE A LOT BRIGHTER, BECAUSE IT IS STILL HARD TO SEE AT NIGHT. UPDATED 01/03/17.*JB

THE LOW BEAM PROJECTOR HEADLIGHTS ARE INADEQUATE, ESPECIALLY IN RURAL AREAS. THERE IS A DISTINCTIVE CUTOFF OF LIGHT, CALL IT A LINE WHEN ON LOW BEAM, AND BEYOND THAT LINE THEIR IS NO ILLUMINATION WHATSOEVER AS YOU WOULD BE USED TO WITH OTHER LIGHTING DESIGNS. YOU CAN NOT SEE ANY SIGNS, POSSIBLE ANIMALS, OR ANYTHING ELSE AS YOU ARE USED TO SEEING IN THE LIGHT THAT TYPICALLY EXTENDS BEYOND OTHER LOW BEAM SYSTEMS. I UNDERSTAND THAT GM HAS A TSB FOR THE CONDITION BUT IT IS NOT ADVERTISED AND FROM WHAT I CAN DETERMINE ON THE NET DOES NOT WORK REGARDLESS AND IS ONLY A BAND AID FIX. THESE LIGHTS ARE A SAFETY HAZARD. I BELIEVE THIS ISSUE MAY HAVE CONTRIBUTED TO AN ACCIDENT I HAD. ..UPDATED 01/04/17 *BF

THE HEADLIGHTS ON THE TRUCK ARE A SERIOUS HAZARD. WHILE DRIVING AT NIGHT YOU CAN ONLY SEE ABOUT 20FT OUT IN FRONT OF THE VEHICLE. IT'S EVEN WORSE WHEN IS RAINING.

THE HEADLIGHTS ARE NOT SUFFICENT. NIGHT DRIVING IS TERRIBLE, CAN NOT SEE ROAD. I HAVE SPOKEN TO GM SEVERAL TIMES. THEY CAME OUT WITH AN UP DATE, SAYING NEW BULBS AND REPOWER CONTROL MODULE, BUT THEY ARE STILL HORRIBLE. GM HAD THESE LIGHTS FOR TWO YEARS ON THE NEW BODY STYLE FOR THE SIERRA LINE, AND NOW HAVE SWITCHED TO LED HID'S. SO THE PEOPLE WHO OWN 2014 AND 2015 TRUCKS ARE STUCK.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 2500. WHILE DRIVING VARIOUS SPEEDS, THE PROJECTOR HEADLIGHTS FAILED TO ADEQUATELY ILLUMINATE THE ROAD. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TCM AND BULBS WERE CHANGED PER TSB NUMBER: PIT5374 (EXTERIOR LIGHTING). THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

THE HEADLIGHTS OFFER VERY POOR PERFORMANCE AT NIGHT

I LIVE IN THE MOUNTAINS OF TEHACHAPI, CANNOT SEE A THING WHEN DRIVING THE MOUNTAIN ROADS. MAYBE 40-50 FEET IN FRONT OF THE TRUCK NOTHING TO THE SIDE. MAKING A TURN IS LIKE ALMOST DRIVING WITHOUT LIGHTS.

DRIVERS SIDE, IN-MIRROR (WITH EXTENDABLE, MANUAL, TRAILER MIRROR) TURN SIGNAL TOO BRIGHT OR SHOULD BE SHIELDED FROM DRIVERS EYES. BLINDINGLY BRIGHT FOR MAKING LEFT-HAND TURNS. PROBLEM WORSENS AS AMBIENT LIGHT IS REDUCED.

THE HEADLIGHTS ARE NOT BRIGHT ENOUGH TO LIGHT THE ROADWAY SUFFICIENTLY AT NIGHT WHILE DRIVING, ESPECIALLY ON DARK RURAL ROADS AND DURING HAZARDOUS WEATHER SITUATIONS SUCH AS RAIN OR FOG. THE DIM LIGHT DOES NOT ALLOW THE DRIVER TO EFFECTIVELY SEE ROAD HAZARDS, PEDESTRIANS, BICYCLISTS, ANIMALS OR OTHER OBSTACLES THAT MAY APPEAR AND THUS IS A SAFETY HAZARD.

Mileage: 13,000

THE HEADLIGHTS ON THE GMC 2500 HD ARE NOT BRIGHT ENOUGH. THE LIGHTS ARE NOT ABLE LIGHT ROADS WITHOUT STREET LIGHTS, MAKES IT VERY DANGEROUS. FUEL FILTER HAS BEEN REPLACED TWICE AND MY TRUCK ONLY HAS 12,000 MILES ON IT. WHEN I ASKED WITH THE LIFE OF A FUEL FILTER SHOULD BE I WAS TOLD BY THE GMC DEALERSHIP AT LEAST 15,000 MILES. IT IS POSSIBLE THERE IS A MALFUNCTION WITHIN THE SENOR FOR THE FUEL FILTER.

Mileage: 1,000

HEADLIGHTS AREN'T WIDE ENOUGH MAKING IT VERY DANGEROUS TO MAKE A LEFT OR RIGHT TURN AND VERY DANGEROUS IN MOUNTAINOUS AREAS GMC FINALLY PUT BRIGHTER BULBS IN AND HASN'T FIXED THE PROBLEM. THIS HAS BEEN ONGOING SINCE MAY 2014 AND GM DOESN'T CARE.

THE HEADLIGHTS DO NOT PROVIDE ADEQUATE LIGHTING OF THE ROAD WHICH MAKES IT VERY DIFFICULT TO DRIVE SAFELY AT NIGHT . I HAVE TRIED TO WORK THROUGH GMC THEY CHANGED THE BULBS TO A DIFFERENT VENDOR BUT DIDN'T HELP. GMC NOW IN THE 2016 ARE USING HID BULBS THEY ALSO USED A DIFFERENT LIGHTING SYSTEM IN THE 2014 . THE LOCAL GMC DEALER AGREES THAT THE LIGHTING COULD LEAD TO POSSIBLE ACCIDENT . THE LUMEN OF THE BULBS ARE DOWN AROUND 1200 WHICH IS HALF OF THE NORMAL LUMENS TO PROVIDE ADEQUATE STOPPING OR VISUAL OF THE ROAD. PLEASE HELP US OWNERS AS THIS VEHICLE IS VERY DANGEROUS TO DRIVE AFTER DARK. *DT

THE HEADLIGHTS ON 2015 SIERRA 2500HD DENALI ARE SAFETY HAZARDS THEY DO NOT ILLUMINATE FAR ENOUGH AHEAD OF YOU AT NIGHT TO SEE ROAD HAZARDS IN FRONT OF YOU AT NORMAL DRIVING SPEEDS, THEY ARE ESPECIALLY LACKING ON RURAL ROADS, WHERE ANIMALS MIGHT BE ON THE ROADWAY. THEY BARELY ILLUMINATE (VERY DIM AND UNREADABLE), THE LICENSE PLATE ON A VEHICLE IN FRONT OF YOU TRAVELING AT REGULAR NIGHT TIME DISTANCES, GIVING YOU VERY LITTLE REACTION TIME TO REACT IN CASE OF HAZARDS. WE HAVE A NEW VEHICLE LESS THAN 3000 MILES AND FIND THIS VEHICLE VERY DANGEROUS TO DRIVE AT NIGHT OR IN POOR LIGHTING. THE DEALER TOLD US THERE WAS NOTHING THEY COULD DO, CONSIDERING TRYING TO FIND SOME TYPE OF AFTER MARKET LIGHTING TO ADD TO THE VEHICLE TO AID IN NIGHT TIME DRIVING.

WHILE DRIVING AT NIGHT ON RURAL HIGHWAYS, TOWING MY FIFTH WHEEL TRAILER, IN AZ, CA AND OR WITH NO OTHER LIGHT SOURCES NEARBY THE HEADLIGHTS WERE DIMMER THAN THOSE I AM USED TO MAKING WILD ANIMALS AND PEOPLE ALONG THE ROAD DIFFICULT TO SEE. THE INSTANCES WHEN I NOTICED THIS WERE ALL IN SEPTEMBER 2015 . THIS MORNING MY DEALER, ROBIDEAUX MOTORS IN COEUR D'ALENE, ID, CHECKED OUT THE PROBLEM AND TOLD ME THAT THE LIGHTS APPEARED THE SAME AS OTHER SIMILAR MODELS AND THEY COULD NOT DUPLICATE THE ISSUE (REPAIR ORDER #193940). I WAS NOT SURPRISED AS I HAVE SEEN NUMEROUS SIMILAR REPORTS ON INTERNET BLOGS AND I EVEN UNDERSTAND GM IS BEING SUED OVER THE SAME ISSUE (2013 AND 2014 MODELS) IN A CASE IN CALIFORNIA.

Mileage: 4,000

I HAVE THE TOW MIRRORS AND THEY HAVE LED LIGHTS IN THE MIRRORS FOR BLINKERS AND THEY ARE EXTREMELY BRIGHT! WHEN YOU USE YOUR TURN SIGNAL AT NIGHT THEY ARE SO BRIGHT THAT THEY MAKE IT SO YOU CAN NOT SEE ON COMING TRAFFIC VERY WELL FROM THE SIDES OF THE PICKUP WHILE AT A INTERSECTION OR WHEN YOU ARE TRYING TO CHANGE LANES. IN MY OPINION THIS IS EXTREMELY DANGEROUS. THE BLINKER LEDS SHOULD NOT SHINE DIRECTLY INTO THE DRIVERS EYES. *TR

VEHICLE LOW BEAM HEAD LIGHTS HAVE VERY POOR COVERAGE AND BRIGHTNESS. WHEN DRIVING AT NIGHT THEY BARELY LIGHT THE ROAD IN FRONT OF THE VEHICLE. COVERAGE SIDE TO SIDE IS VERY WEAK. ADDITIONALLY WHEN IT IS RAINING OUT, IT IS LIKE DRIVING WITH NO HEADLIGHTS ON AT ALL. I HAVE CONTACTED THE DEALER AND THEY HAVE INDICATED THIS IS COMMON COMPLAINT ON 2014 SIERRA 1500S AND ALL 2015 SIERRAS SINCE THE LAST REDESIGN.
