THE HEADLIGHTS ARE VERY POOR.IT IS EASY TO OVER DRIVE THEM.DARK ROADS OR RAIN OR SNOW IT IS DANGEROUS TO DRIVE.

NHTSA ODI 10907984

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

WHILE DRIVING ON DRY PAVEMENT, DRIVER MOVED KNOB ON VEHICLE TO SWITCH FROM AWD TO 2WD. VEHICLE WENT INTO AN IMMEDIATE SPIN WHICH COULD NOT BE CORRECTED. (OR MAYBE IT WAS BECAUSE OF WHAT HAPPENED NEXT). VEHICLE CAREENED OVER TWO LANES ("PRESUMABLY" WOULD NOT STOP - DRIVER DOES NOT RECALL TRYING TO HIT THE BRAKES REPEATEDLY OR AT ALL AS THE "NEXT PROBLEM" WAS IN FRONT OF DRIVER AND DRIVER WAS FOCUSING ON SURVIVAL).. DRIVER QUICKLY SMASHED THROUGH METAL SAFETY BARRIER AND CRASHED THROUGH TREES OVER A 30 FT EMBANKMENT INTO A RESERVOIR. DRIVER ABLE TO OPEN ROOF WHILE "STEERING" WITH LEFT HAND AND OPENING ROOF WITH RIGHT HAND AS DRIVER KNEW WATER WAS FAST APPROACHING. DRIVER SMASHED THROUGH TREES, TRUCK WAS DEMOLISHED BUT DRIVER WAS ABLE TO MAKE IT OUT OF CAR ALIVE AS CAR TOOK ON WATER THROUGH OPENED ROOF. VIN NUMBER REPORTS BRAKE ISSUES. DRIVER NOT AWARE OF "BRAKE RECALL" OR ANY ISSUES AND DID NOT REPORT BRAKE ISSUE AS AN ISSUE ON SCENE AS INCIDENT HAPPENED SO FAST AND DRIVER WAS ATTEMPTING TO STAY ALIVE AND WAS EVER FOCUSED ON THE NEXT 'OBSTACLE" AS IT WAS IN THE WAY PER DESCRIPTION HEREIN. AIRBAGS DEPLOYED AS EXPECTED AND DRIVER EXITED WATER-FILLED VEHICLE VIA OPENED ROOF UNHARMED. GMC SENT INVESTIGATORS OUT BUT NO REPORT HAS BEEN ISSUED TO DRIVER. CHUBB LEAD INVESTIGATOR ACCOMPANIED THE GMC INVESTIGATOR AND REPORTED "NO VEHICLE MALFUNCTION". AFTER THIS INCIDENT, AND READING OTHERS' PROBLEMS, DRIVER IS NOW NOT CONVINCED OF THAT REPORT.. NO MENTION OF BRAKE RECALL SEEMS TO HAVE BEEN REPORTED BY ANYONE BUT BY PUTTING VIN NUMBER INTO THIS DATABASE.

WHILE DRIVING STRAIGHT/UPSLOPE ON A DIRT ROAD THE SIDE AIR BAGS DEPLOYED IN MY 2015 SIERRA 2500 HD PICKUP TRUCK. THERE WAS NO IMPACT AND ABSOLUTELY NO DAMAGE TO THE EXTERIOR OR UNDERCARRIAGE OF THE VEHICLE.

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.

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 .

WHEN AT SPEEDS OF ROUGHLY 50MPH SEATS VIBRATE. TRUCK HAS ROUGHLY 3000MILES AND THE FRAME, REAREND AND OTHER UNDERBODY COMPONENTS HAVE ALOT OF SURFACE RUST

NHTSA ODI 10853196

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.

I HAVE BEEN HAVING A PROBLEM WITH THE TRAILER BRAKE CONTROLLER ON MY K3500 TRUCK. RECENTLY THE MESSAGE "CHECK TRAILER WIRING" HAS BEEN COMING ON FREQUENTLY. AT THE SAME TIME, THE BRAKING CONTROLLER SHUTS OFF POWER TO THE TRAILER BRAKES. THIS HAS RESULTED IN A VERY UNSAFE CONDITION, ESPECIALLY WITH A TRAILER THAT WEIGHS OVER 14,000 POUNDS. THIS HAS BEEN GOING ON FOR 6 MONTHS NOW. REPEATED ATTEMPTS BY BOTH THE GMC DEALER AND THE TRAILER DEALER HAVE FAILED TO RESOLVE THE PROBLEM. I HAVE BEEN TOLD, BY THE DEALER, THAT THE PROBLEM STARTED APPROXIMATELY WITH THE 2014 MODELS. THE BRAKE CONTROLLER HAS BEEN UPGRADED, AND MADE MUCH MORE SENSITIVE TO SLIGHT DEVIATIONS IN THE TRAILER SYSTEM, CAUSING THE CONTROLLER TO "SHUT OFF" SO TO SPEAK. WHILE THIS WOULDN'T BE A BIG ISSUE NORMALLY, WHEN IT SHUTS OFF, YOU LOSE ALL BRAKING ABILITY TO THE TRAILER RESULTING IN AN UNSAFE CONDITION. THERE IS NO WAY TO OVERRIDE THIS AND ACTIVATE THE BRAKES. WHAT SEEMS TO BE HAPPENING IS A VERY SLIGHT DEVIATION IN THE RESISTANCE IN THE TRAILER BRAKE SYSTEM (BY 1 OHM OR LESS) AND THAT CAUSES THE "SHUTDOWN" IN THE CONTROLLER. TRAILER BRAKES WOULD WORK, IF THEY COULD GET POWER. BUT, THE CONTROLLER HAS SHUT DOWN, SO NO POWER. MYSELF (AND THE TRAILER SHOP) HAVE BEEN CHECKING THE INTERNET AND FINDING THAT THIS IS NOT AN ISOLATED INCIDENT. IT APPEARS TO BE HAPPENING WITH ALL THE BIG THREE MANUFACTURER TRUCKS, SINCE ABOUT 2014. PEOPLE HAVE BEEN COMING UP WITH SOME RATHER "CREATIVE" WAYS AROUND THIS, IN SOME CASES ELIMINATING THE ORIGINAL SYSTEM ENTIRELY. THIS IS JUST NOT ACCEPTABLE. AGAIN, THIS "NEW SYSTEM THE BIG THREE ARE PUTTING IN IS FAR WORSE THAT THE OLD, SIMPLY BECAUSE IT HAS NO ROOM FOR FORGIVENESS IN A TRAILER SYSTEM THAT MIGHT WORK OTHERWISE, BUT HAS A SLIGHT DEVIATION IN WHAT IS CONSIDERED "ACCEPTABLE" TO THE CONTROLLER. AT THE VERY LEAST, THERE SHOULD BE A FAIL SAFE METHOD.

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.

NHTSA ODI 10851271

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 ODI 10850161

MY VEHICLE SHAKES AT HIGHWAY SPEED. I CAN FEEL IT IN THE STEERING WHEEL, AND SEAT. VISUALLY I CAN SEE THE BED OF THE TRUCK SHAKE. THE ISSUE HAS NOT GONE AWAY.

NHTSA ODI 10849897

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 ODI 10850003

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 ODI 10849881

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.

NHTSA ODI 10845894

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 ODI 10840233

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 ODI 10840159

DRIVING NORTH ON THE GARDEN STATE PARKWAY IN THE CENTER LANE IT FELT LIKE I HAD A BACK TIRE BLOWOUT BUT WHAT HAPPENED WAS MY REAR AXLE BROKE CAUSING MY VEHICLE TO BE EXTREMELY HARD TO CONTROL. I WAS TRYING TO STEER THE VEHICLE BUT COULD NOT CONTROL THE TRUCK, IT FELT LIKE I HAD LIMITED BRAKING ABILITY, SMASHING INTO GUARDRAIL IT FINALLY CAME TO A STOP.

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.
