  DASH HAS CRACKED AROUND THE PASSENGER SIDE AIR BAG COVER. IF IT GOES OFF IT COULD SPLINTER AND CAUSE HARM.

• 12/29/2014· EXTERIOR LIGHTING

  THE HEADLIGHTS ON THIS TRUCK ARE UNSAFE. THEY DO NOT PUT OUT ENOUGH LIGHT ON DARK NIGHTS AND ESPECIALLY ON NIGHTS WERE THERE IS RAIN. THEY DO NOT REACH BEYOND THE EDGE OF THE ROAD WAY PAST THE FOG LINES,. OR EXTEND THAT FAR UP THE ROAD IN FRONT OF THE TRUCK. *TR

• 12/29/2014· EXTERIOR LIGHTING,VISIBILITY/WIPER

  THE HEADLIGHT PERFORMANCE ON THIS TRUCK IS THE WORST I'VE SEEN IN ANY VEHICLE, BUT FOR A TRUCK, I CANNOT BELIEVE THEY ARE ALLOWED ON THE ROAD AT NIGHT. THE OWNER'S MANUAL STATES THEY ARE FACTORY SET AND DO NOT NEED ADJUSTMENT. THAT INFORMATION WAS OBVIOUSLY NOT CHECKED DURING THE QUALITY CHECK OR CHECKED BUT FELT IT WAS AS GOOD AS IT GETS. ON HIGH BEAM, THE DRIVER'S SIDE LIGHT IS POINTING SO FAR UP, IT'S IN THE TREES AND ABOVE THE ROAD. THE RIGHT SIDE HIGH AND LOW BEAMS ARE INADEQUATE FOR ALL PURPOSES, ESPECIALLY SEEING AROUND CURVES AND TURNS. YOU ARE LITERALLY BLIND ON A DARK STREET, EVEN WITH THE FOG LIGHTS. VERY POOR ILLUMINATION OF THE ROAD. I'VE TAKEN IT IN TO THE DEALER FOR ADJUSTMENT AND THEY DID NOT CHANGE ANYTHING. THIS WILL BE THE LAST GM PRODUCT I BUY SINCE IT SEEMS THE LAST THREE VEHICLES I'VE OWNED HAD ISSUES THAT COULD NOT BE RESOLVED. AND I AM A MEMBER OF THE GM FAMILY. FOR THE PRICE OF THESE VEHICLES, THEY SHOULD BE TOP QUALITY. GM SHOULD BE ASHAMED OF THE QUALITY THEY DELIVER TO CUSTOMERS FOR VEHICLES PRICED OVER $45K. *TR

• 12/21/2014· EXTERIOR LIGHTING

  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

• 12/19/2015· EXTERIOR LIGHTING

  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 !

  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

• 12/15/2014· EXTERIOR LIGHTING

  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

• 12/14/2014· EXTERIOR LIGHTING

  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

PROBLEMS WITH ENGINE RUNNING, BEFORE ALL THIS HAPPENED I WAS GETTING 20/22 MPG ON THE HIGHWAY WHICH IS WHAT I TRAVEL MOSTLY, NOW SINCE THIS HAPPEN I ONLY GETTING 16/18 MPG ON THE HIGHWAY. MY DEALERSHIP IN MILWAUKEE WORKED WITH AN ENGINEER FROM GM AND THEY CLAIM EVERYTHING UP TO SPEC AND WON'T DO ANYMORE ON THE VEHICLE BUT YET SOMETHING HAS HAPPENED THAT I HAVE LOST ABOUT 4/6 MPG HIGHWAY OR $20 PER TANK WHICH WITH MY TRAVELING IS A LOT OF MONEY $400 MONTH. I AM VERY DISSATISFIED WITH GM AND THIS VEHICLE RIGHT NOW WHEN YOU PAY $50,000 + FOR A VEHICLE YOU DON'T EXPECT TO HAVE PROBLEMS WITHIN THE FIRST MONTH OF PURCHASE (BRAND NEW) AND THEN FOR GM NOT TO FIND OUT WHY THE DROP IN MILEAGE IS UNACCEPTABLE. *TR

  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

• 11/23/2014· EXTERIOR LIGHTING

  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

• 11/21/2014· EXTERIOR LIGHTING

  BOUGHT VEHICLE NEW IN MARCH '14, HEADLIGHTS ARE HID UNITS, AND ARE WORSE THAN POOR. VERY EASY TO OVERDRIVE THESE LIGHTS HERE ON DARK, TWISTY MOUNTAIN ROADS IN WV. WE HAVE THE HIGHEST RATE OF VEHICLE- DEER COLLISIONS IN THE US AND SEEING DEER WITH THESE LIGHTS IN TIME TO AVOID A COLLISION IS CHANCY. TRADED A 10 YEAR OLD SAME MAKE AND MODEL AND NEVER HAD THESE PROBLEMS. THESE LIGHTS NEED TO BE CORRECTED BEFORE FOLKS ARE KILLED AS A RESULT. *TR

• 11/17/2023· AIR BAGS

  2014 GMC Sierra 2500HD. My dash has started to crack around the passenger airbag and driverside gauge cluster. Dash material is brittle and serves as a hazard should the airbags deploy during an accident.

• 11/15/2015· ELECTRICAL SYSTEM,EXTERIOR LIGHTING

  THE VEHICLES HEADLIGHTS ARE DANGEROUSLY INEFFECTIVE. THEY RARELY ILLUMINATE THE DISTANCE BETWEEN 2 TELEPHONE POLES. THE INEFFECTIVENESS OF THE HEADLIGHTS IS AMPLIFIED ON HILLS OR ON ANY TURN. THE DURING THE TRANSITION FROM DECLINE TO INCLINE, YOU SOMETIMES HAVE BARELY A TRUCKS LENGTH OF ILLUMINATION. ANY CORNER ON A DARK ROAD REQUIRES A SEVERE DECREASE IN TRAVEL SPEED TO AVOID OVER DRIVING THE LIGHTS. I HAVE NEVER DRIVEN A VEHICLE THAT MADE ME FEEL MORE APPREHENSIVE TO GET BEHIND THE WHEEL AFTER DARK. I VISITED THE DEALER WHO EXECUTED A TSB THAT INCREASED HEADLIGHT VOLTAGE AND REPLACED THE BULBS. IT MADE A NEGLIGIBLE IMPROVEMENT AND LEFT THE VEHICLE STILL UNSAFE AT NIGHT. I FREQUENTLY TRAVEL ON RURAL ROADS WITH NO STREET LIGHTS. I HAVE ALMOST HIT WILDLIFE TOO MANY TIMES TO COUNT DUE TO THE POOR VISIBILITY CAUSED BY THESE DANGEROUS HEADLIGHTS. TRAVEL OVER 30 MPH ON DARK COUNTRY ROADS WITH A LEGAL SPEED LIMIT OF 50 IS ILL ADVISED DUE TO THE INEFFECTIVENESS OF THE HEADLIGHTS.

• 11/13/2017· FUEL/PROPULSION SYSTEM

  MY FUEL PUMP AND INJECTORS FAILED WHILE I WAS DRIVING, STRANDING MY TRUCK IN THE MIDDLE OF TRAFFIC RIGHT WHERE A CITY STREET WAS CHANGING TO A COUNTRY ROAD. THE GMC DEALERSHIP FALSELY CLAIMED THAT THIS WAS CAUSED BY USING UNAPPROVED FUEL. THE FUEL I USED WAS B20 BIODIESEL, WITH 80% RENEWABLE DIESEL, WHICH MEETS DIESEL SPECIFICATIONS AND IS A LEGAL ROAD FUEL IN CALIFORNIA. THEY ALSO CLAIMED THAT A CASCADE OF OTHER PROBLEMS WERE ALL CAUSED BY MY FUEL AND REFUSED TO APPLY MY WARRANTY.

• 11/12/2013· SEATS

  I HAVE A 2014 GMC SIERRA SLT WITH POWER SEATS. THE DRIVER'S SEAT IS LOOSE (NOT THE SAME ISSUE THAT WAS RECENTLY RECALLED WITH MANUALLY RECLINING SEATS). WHEN YOU MAKE A SHARP TURN AT SPEED THE DRIVERS SEAT SLIDES LEFT OR RIGHT DEPENDING ON THE DIRECTION YOU ARE TURNING. THERE ARE NUMEROUS COMPLAINTS IDENTICAL TO THIS ONE ON THE FORUMS ONLINE AND GM CLAIMS THEY HAVE NO SOLUTION AND TO SPEAK WITH THE LOCAL DEALER. MY LOCAL DEALER DOES NOT NOW KNOW WHAT TO DO AND SAYS THEY CANNOT FIX IT. THIS IS A VERY DANGEROUS SITUATION AND COULD CAUSE AN ACCIDENT! PLEASE HAVE GM FIX IT OR ISSUE A RECALL! *TR

• 11/09/2015· EXTERIOR LIGHTING

  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 .

• 11/06/2014· EXTERIOR LIGHTING,VISIBILITY/WIPER

  THIS VEHICLE HAS THE WORST HEADLIGHTS OF ANY NEW VEHICLE I'VE EVER OWNED. IT SEEMS DANGEROUS TO DRIVE AT NIGHT, AND I AVOID IT WHERE I CAN. THE BEAM PATTERN IS AWFUL AND THE ILLUMINATION IS POOR. I'VE BEEN DRIVING CARS WITH PROJECTOR HEADLIGHTS FOR YEARS, SO I KNOW THAT IS NOT THE REAL ISSUE. THESE LIGHTS ARE JUST POORLY DESIGNED OR CHEAP. TRIPS TO THE DEALER ARE UNFRUITFUL. THE DEALER KNOWS THEY ARE POOR, BUT CAN DO NOTHING EXCEPT BE SURE EVERYTHING IS PROPERLY ADJUSTED. IF YOU ARE LOOKING AT BUYING A 2014 GMC PICKUP, BUY SOMETHING ELSE. THEY ARE THAT BAD. I JUST KNOW I'M GOING TO HIT A DEER SOON ENOUGH. *TR

• 11/03/2015· UNKNOWN OR OTHER

  THE FACTORY SUPPLIED RUNNING BOARDS HAVE TREADS THAT FAIL TO PROVIDE ANY TRACTION FOR FEET WHILE ENTERING OR EXITING. THE TREADS NEED TO BE ROTATED 90 DEGREES AND MADE OF A SOFTER RUBBER WITH A DEEPER AND MORE AGGRESSIVE TREAD PATTERN. AS THEY EXIST THEY ARE VERY SLIPPERY ESPECIALLY WHEN WET OR FROZEN. GIVEN THE ADDED HEIGHT OF TRUCKS IT REQUIRES SOME USE OF THE RUNNING BOARDS TO ENTER/EXIT THE TRUCK. ESPECIALLY WHEN YOU ARE 68. AS DESIGNED AND MANUFACTURED THEY ARE ACTUALLY AN ACCELERANT IN SLIPPING FEET. I FEEL THEY ARE OF DEFECTIVE DESIGN AND MANUFACTURE AND COULD/SHOULD BE MADE SAFER. I FELL THREE TIMES IN THE PAST MONTHS WHILE EXITING MY SIERRA 1500.

• 11/03/2014· EXTERIOR LIGHTING

  HEADLIGHTS IN NORMAL OPERATION SITUATION ARE WOEFULLY SHORT OF ILLUMINATION DISTANCE AND EASY TO OVERDRIVE AT HIGHWAY SPEEDS. HIGH BEAMS AND FOG LIGHTS ARE MORE ADEQUATE, HOWEVER HIGH BEAMS CANNOT BE USED IN TRAFFIC AND FOG LIGHTS TEND TO IRRITATE ONCOMING DRIVERS ON HIGHWAYS IN SMALLER VEHICLES. *TR

  REGARDING 2014 GMC SIERRA 6 CYLINDER FULL SIZE PICKUP. VEHICLE VIBRATES AS IF RUNNING OVER RUMBLE STRIPS AT APX 1500 RPM. LOCAL GM SERVICE CENTER AND GM CORPORATE REPRESENTATIVE STATED ABOVE IS NORMAL VEHICLE OPERATION. LOCAL GM SERVICE CENTER CORRECTLY SUGGESTED THAT TRUCK BE DRIVEN FASTER OR SLOWER TO PREVENT VIBRATION OR THAT VEHICLE BE DRIVEN IN 5TH GEAR RATHER THAN OVERDRIVE 6TH GEAR TO PREVENT VIBRATION. IF VEHICLE IS NOR DRIVEN FASTER OR SLOWER TO GET OUT OF VIBRATION RANGE, THE TRUCK WILL VIBRATE ENDLESSLY. 2014 GMC SIERRA IS AN UNSAFE VEHICLE. NEEDING TO SPEED UP OR SLOW DOWN TO PREVENT VIBRATION SIGNIFICANTLY INCREASES RISK FOR MVA. NEEDING TO DRIVE IN 5TH GEAR RATHER THAN 6TH GEAR REDUCES GAS MILEAGE AS REPORTED TO NHSTA. LOCAL MECHANICS HAVE COMMENTED THAT THE ABOVE VIBRATION COMPLAINT IS COMMON TO 2014 6 CYLINDER GMC/CHEVY FULL SIZE PICKUP TRUCKS AND THAT THE VIBRATION MAY BE SECONDARY TO CYLINDER DEACTIVATION AND CHASSIS RIGIDITY. IT CERTAINLY WOUND BE A SHAME FOR A COLLISION TO OCCUR OR FOR A PEDESTRIAN TO GET RUN OVER BY A DRIVER OF A 2014 GMC/CHEVY FULL SIZE PICKUP WHO HAD TO SPEED UP OR SLOW DOWN TO REDUCE EXCESSIVE VIBRATION AT APX 1500 RPM

  WHEN WE TOOK OUR NEW TRUCK FOR A TEST DRIVE WE NOTICED A VIBRATION. THE DEALERSHIP SUPPOSEDLY CHECKED IT OUT AND TOOK CARE OF IT. WHEN TOOK DELIVERY OF THE TRUCK AND DROVE IT HOME THE VIBRATION WAS BETTER AT A SLOWER SPEED BUT INCREASED AS THE SPEED INCREASED. WE RETURNED THE TRUCK TO THE DEALERSHIP AND THEY CHECKED IT OUT AND SAID THAT THEY BALANCED THE TIRES AND ROTATED THE DRIVESHAFT 180 DEGREES. IT SEEM TO BE A LITTLE BETTER. BECAUSE WE TAKE THIS TRUCK TO FLORIDA FOR THE WINTER AND IT IS LOADED MY HUSBAND DECIDED THAT HE WOULD PUT SOME WEIGHT IN THE BACK OF IT TO SEE HOW IT WOULD AFFECT IT. THE VIBRATION WAS BETTER AT A SLOWER SPEED AND WORSE AT A HIGH SPEED ON THE HIGHWAY. THE TRUCK HAS NOW BEEN BACK AT THE DEALERSHIP FOR A WEEK AND WE HAVE NOT HEARD ANYTHING IN REGARDS TO IT. THEY ARE SUPPOSED TO BE DOING AN ELECTRONIC VIBRATION ANALYSIS ON IT. MY HUSBAND HAS RESEARCHED THIS PROBLEM ON THE INTERNET AND THERE SEEMS TO BE A LOT OF COMPLAINTS ABOUT THIS PROBLEM. HOPEFULLY PEOPLE ARE REGISTERING THEM ON YOUR WEBSITE. *TR

  The contact owns a 2014 GMC Sierra. The contact stated that while making a right turn into the driveway, the steering wheel had become stiff. No warning light had illuminated. The vehicle was no longer being driven since the steering wheel was too stiff and required excessive force causing control to be lost while driving. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 105,000.

• 10/17/2014· EXTERIOR LIGHTING

  IT WAS THE FIRST TIME I DROVE THIS NEW GMC AT NIGHT AND I COULDN'T SEE ANYTHING ALMOST HIT A HUGE MOOSE CAUSE I DIDN'T SEE IT. THE HEADLIGHTS ARE AWFUL AND ITS TERRIFYING TO DRIVE AT NIGHT. WENT TO DEALER AND TOLD THEM ABOUT THE HEADLIGHTS THEY SAID THEY HAD NUMEROUS COMPLAINTS BUT GM HAS NO FIX. THESE HEADLIGHTS ARE GOING TO CAUSE MULTIPLE ACCIDENTS SIMPLY DRIVING 45 MPH FEELS LIKE YOU CAN OUT RUN THE HEADLIGHTS IN HIGH BEAM. *TR

• 10/16/2014· EXTERIOR LIGHTING

  THE HEADLIGHTS ARE SO GOOD, THEY HELPED TO SAVE THE LIFE OF SEVERAL DEER WHICH I COULD CLEARLY SEE UP AHEAD, JUST ABOVE THE CREST OF THE ROAD. THE DEER STARTED TO DASH ACROSS THE ROAD, WHICH WAS NOT LIT, AND I COULD CLEARLY SEE THEM AND PROPERLY STEERED CLEAR OF THE DEER. THE HEADLIGHTS ON THIS TRUCK ARE THE BEST I HAVE EVER HAD !! I FIND THE 2014 GMC SIERRA AS THE MOST WELL EQUIPPED VEHICLE I HAVE EVER DRIVEN. MY COMPLAINT IS NOT REALLY ABOUT THE LIGHTS OR HOW WELL I COULD SEE THE DEER ON THE SIDE OF THE ROAD, IT'S ABOUT THE NEED FOR OTHER BRANDS OF VEHICLES THAT ARE NOT EQUIPPED WITH THESE TYPE OF HEADLIGHTS. I BELIEVE THIS TYPE OF HEADLIGHT SYSTEM SHOULD BE MANDATORY ON ALL VEHICLES OF ALL MAKES. GMC HAS DONE THE WORLD A FAVOR. NOW IT IS UP TO THE REST TO CATCH UP AND USE THIS TECHNOLOGY! *TR

• 10/15/2014· EXTERIOR LIGHTING

  AFTER PURCHASING OUR NEW TRUCK, WE DROVE IT FOR THE FIRST TIME AFTER DARK ON OUR RURAL COUNTRY ROADS. WHEN ENGAGING THE DIM LIGHTS YOU CAN NOT SEE MORE THAN 20 TO 30 YARDS IN FRONT OF YOUR VEHICLE. MY HUSBAND HAS DONE EXTENSIVE RESEARCH ON THIS PROBLEM SINCE WE DISCOVERED IT AND FOUND HUNDREDS OF COMPLAINTS. WHEN ENGAGING THE BRIGHT LIGHTS THEY APPEAR TO SHINE THE DISTANCE THAT THE DIM LIGHTS SHOULD. WE FEEL THAT THIS IS A SERIOUS ENGINEERING FLAW IN THE GM LIGHTING SYSTEM ON THEIR GMC TRUCKS. HE HAS DISCOVERED THAT THEY HAVE INSTALLED A PROJECTOR LIGHT WITH A CURTAIN OR SHUTTER IN THIS LIGHTING SYSTEM. WE HAVE HAD THEM ADJUSTED ONCE BY THE DEALERSHIP AND THEY MADE IT WORSE NOT BETTER. WE HAVE BEEN TOLD THAT UNTIL GM IS MADE TO CHANGE THE LIGHTING SYSTEM AND REMOVE THIS CURTAIN/SHUTTER SYSTEM THAT WE ARE STUCK WITH THIS. OUR ONLY ALTERNATIVE SEEMS TO BE TO DRIVE WITH OUR BRIGHT LIGHTS ON AT ALL TIMES AFTER DARK IN RURAL AREAS. WE FEEL THAT THIS IS A VERY DANGEROUS SITUATION AND AT SOME POINT IN TIME THERE IS GOING TO BE A SERIOUS IF NOT FATAL ACCIDENT DUE TO THIS PROBLEM. WE ARE HOPING THAT YOU WILL INVESTIGATE THIS MATTER AND TAKE ACTION AS SOON AS POSSIBLE. *TR

• 10/13/2015· ELECTRICAL SYSTEM

  THE HEADLIGHTS ON THIS TRUCK PROVIDE INADEQUATE LIGHTING, INCLUDING BOTH LOW BEAMS AND HIGH BEAMS. ANY NIGHT DRIVING IS DIFFICULT DUE TO LIMITED VISIBILITY, THERE SIMPLY IS NOT ENOUGH ILLUMINATION TO SEE. CAN BE VERY DANGEROUS - ESPECIALLY AT SPEEDS ABOVE 35 MPH OR DURING PRECIPITATION. THE HEADLIGHT HAS A SEVERE DESIGN FLAW WITH GMS SAYS IS A SHUTTER SYSTEM. THIS TYPE OF DESIGN DOES NOT LEAVE ANY OPTIONS FOR SIMPLY CHANGING THE TYPE OF BULB - THE DESIGN IS ACTUALLY AT FAULT FOR THE POOR VISIBILITY. THE VISIBILITY PROBLEMS SIMPLY CANNOT BE FIXED WITH A DIFFERENT BULB TYPE DUE TO THE SHUTTER DESIGN TYPE. THE NEED FROM A NEW HEADLIGHT WILL SOLVE THE PROBLEM. MANY COMPLAINTS ARE BEING REGISTERED ONLINE RELATED TO THE VISIBILITY PROBLEM. THESE TRUCKS ARE NOT SAFE TO DRIVE AT NIGHT. IF THERE IS A STANDARD FOR MINIMUM HEADLIGHT ILLUMINATION FOR NIGHT TIME DRIVING, THIS MODEL HEADLIGHT NEEDS TO BE REVIEWED IF IT IS MEETING THE MINIMUM STANDARD. NOT SAFE, A DEFINITE PROBLEM THAT NEEDS ATTENTION.

NOT ONLY ARE THE LIGHTS VERY DIM BUT THE SHAPE OF THE BEAM IS ALSO VERY POOR AND AWKWARD . WITH THE CURRENT OEM HEADLIGHT EQUIPMENT, THIS VEHICLE IS UNSAFE TO OPERATE AT NIGHT. I CONTACTED THE DEALER AND THEY TOLD ME THERE WAS NOTHING THEY COULD DO ABOUT IT . I CAN'T EVEN FIND A BETTER BULB BECAUSE GM HAS THE PATENT AND NOT EVEN PIAA CAN MAKE A BETTER BULB. *TR

  GM refuses to repair the defective finish on my truck, their claim is that it only applies to trucks covered under the 3 year -36k warranty. This is a manufacturing defect that they admit to in the attached TSB. There should be a recall mandated for this. We spent a ton of hard earned money on these trucks.

RIGHT THERE TELLS YOU THEY ARE LYING IF THERE WAS NOTHING THEY COULD DO WHY COME BACK AND WORK ON IT AGAIN! BUT AFTER HE GOT DONE IT WAS JUST LIKE IT WAS, I WILL TRY TO LIST SOME OF THE STUFF THAT THEY SAID THEY DID, 1) ROTATED THE TIRES 2) RE-TORQUE THE WHEELS 3) BALANCED THE TIRES 4) BALANCED THE DRIVE SHAFT 5) SHIMMIED THE REAR END 6) CHECKED THE REAR SHOCKS 7) TOOK OFF DEALER INSTALLED MUD FLAPS! 8) CHECKED THE EXHAUST SYSTEM, I KNOW BUT THEY DID 9) ROAD FORCED TESTED THE TIRES TWICE AND REPLACED TWO THE SECOND TIME AND RE-BALANCED THE TIRES. AND I'M SURE I HAVE NOT LISTED ALL THEY HAVE TRIED, AND STILL I HAVE THE SAME PROBLEM, THIRD TIME THE ENGINEER CAME OUT HE HAD THE REGIONAL MANAGER WITH HIM AND THIS TIME THEY DROVE MY TRUCK AND 2 OTHERS THEY HAD ON THE LOT AND SAID THAT THEY ARE SIMILAR TO MINE AND THEY WAS NOT GOING TO DO ANY MORE TO MY TRUCK THAT THEY HAD DONE ALL THEY COULD OR WOULD DO BUT IF I HAD ANY OTHER PROBLEMS TO BRING IT BACK. *TR

THIS SHOULD BE CONSIDERED A SAFETY HAZARD TO DRIVERS AND ANY OTHERS ON THE ROAD. THIS ISSUE NEEDS TO BE ADDRESSED AND RESOLVED ASAP. AND GM STILL SAYS THERE IS NOTHING WRONG. SO WHY ARE THEY CHANGING THE DESING ON THE 2016'S TRUCKS
