2015 GMC SIERRA 1500 Complaints

THE HEAD LIGHTS ARE INADEQUATE FOR NIGHT DRIVING. BOTH LOW AND HIGH BEAMS DO NOT LIGHT UP ENOUGH AREA IN FRONT OF THE VEHICLE NEARLY AS GOOD AS PREVIOUS MODEL YEARS. THE PROJECTOR STYLE LIGHTS ARE TOO FOCUSED AND DO NOT GIVE ENOUGH LIGHT TO THE SIDES TO SEE ADEQUATELY DOWN THE ROAD. GM IS OBVIOUSLY AWARE OF THE ISSUE AND PERFORMED A BCM UPDATE TO MY VEHICLE TO MAKE THE LIGHTS BRIGHTER BUT THAT FIX STILL DOESN'T RESOLVE THE ISSUE. 2016 MODEL YEARS HAVE A COMPLETELY DIFFERENT HEADLIGHT ALLOWING THOSE TRUCKS TO SEE MUCH BETTER AT NIGHT WHICH TELLS ME THEY ARE AWARE OF THE LIGHTING ISSUES AND FIXED IT FOR THE 2016 GM TRUCKS.

MY 2015 GMC SIERRA'S HEADLIGHTS PROVIDE HORRIBLE VISIBILITY AT NIGHT, THE OEM PROJECTOR STYLE HEADLIGHTS INSTALLED IN THIS TRUCK ARE DIM, WEAK AND UNSAFE. I BROUGHT MY SIERRA BACK TO THE DEALERSHIP AND THEY APPLIED TSB #PIT5374 AND UPGRADED THE HEADLIGHTS WITH THE VOLSA HIR BULBS. THIS UPGRADE PROVIDED A NOMINAL INCREASE IN BRIGHTNESS, BUT THE HEADLIGHTS ARE STILL DIM AND UNSAFE FOR USE WHILE DRIVING ON DARK ROADS OR IN THE RAIN. THE DO NOT PROVIDE ANY ILLUMINATION ON THE SIDE OF THE ROADS, ESPECIALLY ON DARK COUNTRY ROADS WHICH MAKES IT HARD TO SEE WILDLIFE AND OTHER POTENTIAL HAZARDS. THE DESIGN OF THE HEADLIGHTS ON THE 2014/2015 GMC SIERRA ARE SEVERELY DEFICIENT. IT IS MY UNDERSTANDING THAT GMC IS FULLY AWARE OF THIS PROBLEM, SO MUCH SO THAT THEY REDESIGNED THE HEADLIGHTS ON THE 2016 GMC SIERRA WHICH HAS THE SIGNIFICANTLY BETTER HID HEADLIGHTS. I HAVE ALREADY LOGGED A COMPLAINT AND SPOKE WITH REPRESENTATIVES FROM GMC WHO LOOKED INTO MY ISSUE AND THE END RESULT WAS THAT THERE WAS NOTHING ELSE THEY COULD DO.

HEADLIGHTS ARE EXTREMELY DIM. HIGH BEAMS PROVIDE NO ILLUMINATION TO THE FRONT SIDES OF THE VEHICLE. USING FOG LIGHTS WITH LOW BEAM IS ACTUALLY BRIGHTER THAN THE HIGH BEAMS. EVEN AFTER HAVING THE DEALER INSTALL NEW BULBS THE LIGHTING IS VERY WEAK IN A LOW ILLUMINATION AREA, I.E. NO MOON, NO STREET LIGHT, ROAD. WHEN MAKING A TURN IN AN UN LIT AREA I CAN'T EVEN SEE WHERE THE SIDE OF THE ROAD ENDS. THESE SO CALLED PROJECTOR TYPE HEADLIGHTS DON'T SEEM TO WORK VERY WELL. I KNOW FOR A FACT THE 2014 AND 2015 HAVE THE SAME SET UP. THE 2016 HAS A WHOLE NEW SET UP WITH HID LIGHTING AND WORK GREAT. THIS TELLS ME THAT GM KNOWS THERE IS A PROBLEM. UNFORTUNATELY THEIR "FIX" ONLY IF YOU COMPLAIN, ISN'T FIXING ANYTHING... ON A TRIP IN THE SMOKEY MOUNTAINS IN GATLINBURG TN I NEARLY CRASHED OFF THE SIDE OF THE MOUNTAIN. I COULD NOT SEE WHERE THE EDGE OF THE ROAD WAS. EVEN THE PASSENGERS ASKED ME "WHAT IS WRONG WITH YOUR LIGHTS?" THE SAID "TURN ON YOUR HIGH BEAMS" AND I STATED, "THEY ARE ON". WE CAN'T BELIEVE THESE LIGHT PASS THE COMMON SENSE TEST..

ON TWO SEPARATE OCCASIONS MY TRUCK HAS ACTED LIKE IT IS IN NEUTRAL WHILE DRIVING. THE DRIVE SYSTEM DISENGAGES AND THE ENGINE JUST REVS. ONCE THIS HAPPENED WHILE DRIVING DOWN THE ROAD, THE OTHER WHEN THE TRUCK WAS STUCK IN SNOW. WHEN IT WAS STUCK IT DISABLED THE 4WD SYSTEM COMPLETELY, RENDERING THE VEHICLE STRANDED.

2015 GMC SIERRA 1500 HAS A VIBRATION PROBLEM. BEEN IN SHOP 2 TIMES SO FAR WHEELS AND TIRES BALANCED. STILL THE VEHICLES VIBRATES AT SPEEDS 77 AND UP AT 85 YOU CANT STAND TO BE IN VEHICLE HAVE DROVE ON NEW PAVEMENT, INTERSTATE, CHANGED LANES STILL NO CHANGE. I HAVE A VIDEO ON THIS AS WELL AS A LOT OF VIDEOS ON U TUBE TO SHOW VIBRATION AT HIGHWAY SPENDS THIS IS A PROBLEM ON 2014 AND 2015 AND THE DEALERSHIP AND GM STATES THIS IS NORMAL BUT WILL NOT GIVE YOU THAT IN WRITING THEY STATE THEY ALL DO IT.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500 EQUIPPED WITH BRIDGESTONE TIRES, TIRE LINE: DUELER H/T 684 II, AND TIRE SIZE: P255/70R17 (N/A). THE CONTACT STATED THAT THE REAR DRIVER SIDE TIRE HAD LARGE PIECES OF TREAD DETACHING FROM THE CENTER OF THE TIRE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TIRES NEEDED TO BE REPLACED AND THE FAILURE WAS UNDETERMINED. THE TIRES WERE NOT REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE OF THE TIRE AND THE VEHICLE WAS 2,416.

HEADLIGHTS ARE VERY POOR (WHEN WET ROAD OR IN TOWN) CANNOT TELL THEY BURNING...I HAVE 20/20 VISION......ON SLOW DOWN DOES NOT DOWN SHIFT....CANNOT ACCELERATE....THE STARTER HANGS UP ON START AS IF DOES NOT FIRE OR NO FUEL PUMP

THE TRANSMISSION SEEMS TO SLIP OR HESITATE AT TAKEOFF. THE RUNNING LIGHTS ARE TOO DIM TO SEE DOWN THE ROAD.

THE INFOTAINMENT SCREEN IS VERY DISTRACTING WHEN DRIVING AT NIGHT. REGARDLESS OF THE SYSTEM DISPLAYED, (RADIO, PHONE, OR JUST THE CLOCK/OFF SCREEN), THE LIGHTING IS TOO BRIGHT. THIS IS EXTREMELY DISTRACTING TO THE DRIVER. THE DASH LIGHT DIMMER CONTROL SWITCH WORKS THE DASH LIGHTS AND THE INFOTAINMENT SCREEN. IF ONE WERE TO DIM THE DASH LIGHTS SO THAT THE INFOTAINMENT LIGHT IS LOW ENOUGH TO BE ACCEPTABLE, THEN THE DASH LIGHTS ARE TOO LOW TO BE EFFECTIVE AND USED. THE INFOTAINMENT SCREEN SHOULD HAVE A SEPARATE REMOTE SWITCH KNOB TO CONTROL JUST THE INFOTAINMENT SCREEN. I CONTACTED THE GMC CUSTOMER SERVICE #, AND THEY CONFIRMED THAT THIS IS THE WAY IT IS DESIGNED, AND COULD NOT BE ALTERED OR ADJUSTED. CLARIFICATION ON THE DATE OF INCIDENT AND MILEAGE ABOVE, AS THIS HAS OCCUERED SINCE DAY OF PURCHASE.

DRIVING MY NEW 2015 GMC $52,000 GMC SIERRA, I NOTICED A DISTINCT SLIPPING/HESITATION/GENERAL ROUGHNESS WHEN ACCELERATING FROM A DEAD STOP. THE TRUCK SEEMED TO EITHER HAVE A TRANSMISSION OR ENGINE PROBLEM. TOOK IT BACK TO DEALERSHIP FOR THEM TO CHECK, AND THEY INDICATED THAT THIS WAS "NORMAL" AND IT WAS JUST THE "CYLINDER DEACTIVATION" FEATURE PERFORMING AS DESIGNED. I EXPLAINED TO THEM THAT CYLINDER DEACTIVATION ONLY TYPICALLY HAPPENS AT HIGHWAY SPEEDS AND ESPECIALLY NOT FROM A STAND STILL. THEY STUCK BY THEIR STORY AND AGAIN STATED THIS WAS NORMAL. MY SON CAME TO SEE ME AND DROVE MY NEW TRUCK. OF COURSE THE TRUCK HESITATED AND SLIPPED FROM A DEAD START. "WHAT'S WRONG WITH YOUR NEW TRUCK DAD?" HE ASKED. I TOLD HIM IT WAS 'NORMAL AND HE JUST ROLLED HIS EYES. THIS IS NOT NORMAL FOR EVERY SIERRA THAT GMC MAKES WITH THE 5.3 ENGINE AND 6 SPEED TRANSMISSION WOULD DO THIS. I HAVE READ ON NUMEROUS MESSAGE BOARDS AND WEBSITES WHERE THIS IS AN ISSUE AND GM NEEDS TO FIX THE PROBLEM. ALSO, THE HEADLIGHTS ARE EXTREMELY DIM AND ARE BARELY USABLE. AS OTHERS HAVE STATED, I CAN ONLY SEE MAYBE 20-30 FEET IN FRONT OF ME AND NOT VERY BRIGHT AT THAT.
