2015 GMC Sierra 1500 complaints

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.

I LEASED A 2015 GMC PICKUP AND AFTER DRIVING IT AT NIGHT FOUND THAT THE HEAD LIGHTS ARE VERY POOR AND THEY PROVIDE VERY LITTLE VISIBILITY ON LOW BEAM. I TOOK IT TO THE DEALERSHIP AND THE ANSWER IS TO CHANGE A BULBS I WAS TOLD AT THE DEALERSHIP THAT I WOULD MOST LIKELY NOT EVEN NOTICE A DIFFERENCE. THEY ARE CORRECT THE LIGHTS ARE STILL AT A POINT THAT IT IS DANGEROUS TO DRIVE THE TRUCK AT NIGHT. THERE IS A SERVICE BULLETIN ON THESE TRUCKS SO THEY ARE STILL BEING SOLD OFF THE LOT AND THEY ARE DANGEROUS. IF YOU WOULD TAKE THE TIME TO DRIVE ONE AT NIGHT YOU MIGHT HAVE A BETTER IDEA OF WHAT PEOPLE ARE TALKING ABOUT. IF I CAN I AM GOING TO GET RID OF THIS TRUCK AS FAST AS I CAN SINCE GMC DOES NOT SEEM TO WANT TO ACTUALLY FIX THE PROBLEM. IT IS ONLY A MATTER OF TIME BEFORE SOMEBODY IS KILLED DUE TO THIS PROBLEM. I ONLY WISH SOMETHING WOULD BE DONE BEFORE THE DEATHS START TO HAPPEN.

WITHIN 46 HOURS OF PURCHASING THIS BRAND NEW TRUCK HAD 19 MILES AT PURCHASE) IT BROKE DOWN ON ME AND MY KIDS. WE HAD STOPPED AT A STOP LIGHT, PULLED AWAY AND MADE A LEFT HAND TURN ONCE THE LIGHT TURNED GREEN. WE ALL HEARD A WEIRD NOISE COME FROM THE REAR END OF THE TRUCK. THE TRACTION LIGHT CAME ON, THE CHECK ENGINE LIGHT CAME ON AND THE TRUCK STARTED RUNNING VERY ROUGH WITH NO ACCELERATION POWER. I WAS ABLE TO PULL INTO A PARKING LOT. THE TRACTION LIGHT WENT OFF BUT THE CHECK ENGINE LIGHT REMAINED ON. I TURNED THE TRUCK OF AND ON AGAIN. STILL RAN VERY ROUGH, STUTTERING ON ACCELERATION AND STALLED....ALL WITH THE CHECK ENGINE LIGHT STILL ON. CALL GM ROADSIDE ASSISTANCE. THEY GOT A TOW OUT TO PICK UP THE TRUCK IN 2 HOURS. IT WAS RETURNED BACK TO THE DEALERSHIP WHERE I BOUGHT IT. TWO DAYS LATER THEY FELT THAT IT WAS THE FUEL INJECTION SYSTEM AND REPLACE THE PARTS. THEY CALLED AGAIN TO LET ME KNOW THAT EVEN WITH THE REPAIRS THE TRUCK IS STILL RUNNING ROUGH BUT NO LONGER STALLING. THEY WERE UNSURE WHAT WILL NEED TO BE DONE TO REPAIR IT BUT WOULD GET BACK TO ME. NOW WE'RE AT 12 DAYS, STILL NO REPAIR, STILL NO REPAIRED "NEW" TRUCK.

SINCE GM TRANSMISSION SOFTWARE RECALL,TRUCK IS CONTINUALLY SLIPPING IN ALL GEARS,NON AND PARTIAL ENGAGEMENT OF GEARBOX,VERY SLOPPY GEAR CHANGES. THIS IS A MAJOR SAFETY ISSUE,WHILE OPERATING ON THE FREEWAYS OF SOUTHERN CALIFORNIA. HEADLIGHTS ARE NOT WITHIN SAFETY STANDARDS FOR LUMENS AS PER GOVERNMENT HEADLIGHT STANDARDS.THIS IS A SAFETY ISSUE,DEALERSHIP IS AT A LOSS,SINCE GM HAS NOT GIVEN A FIX OR REPLACEMENT FOR THIS PROBLEM.

I RECENTLY PURCHASED A 2015 GMC SIERRA K1500 SLT. I SELECTED THE SLT FOR THE PROJECTOR HEADLIGHTS WHICH ARE NOT OFFERED ON THE LOWER TRIMS FOR IMPROVED LIGHTING. HOWEVER, THE HEADLIGHTS HAVE EXTREMELY POOR ILLUMINATION (CANNOT SEE OFF TO THE SIDE OF THE ROAD, VERY DIM, POOR PROJECTION IN FRONT) IN LOW OR HIGH BEAM. THE HEADLIGHTS ARE THE WORST ON ANY VEHICLE THAT I HAVE OWNED OVER THE PAST 35 YEARS. I ALMOST HIT A DEER ON THE ROAD AT NIGHT, DRIVING 35 MPH, BECAUSE THE DEER COULD NOT BE SEEN IN THE VISIBLE ARC OF THE LOW BEAMS UNTIL TOO LATE. THE DEER WAS STANDING ON THE ROAD FOG LINE. I LOCATED A GM DOCUMENT ON SEVERAL TRUCK FORUMS CONCERNING THIS ISSUE. ORIGINAL DOCUMENT # 4093100, PIT5374 (2/27/2015) AND FOLLOWUP DOCUMENT # 4109395, PIT5374A (3/9/2015).

MADE 1 TRIP OUT OF STATE TO VISIT MY SON AND TO CARRY HIM A BEDROOM SUITE. I LIVE IN GA. AND HE LIVES IN TENN. WHEN I RETURNED I NOTICED FLUID UNDER THE TRUCK. CALLED DEALER IN BRUNSWICK GA. THEY SAID TO BRING THE TRUCK THEN. WHEN TRUCK WAS PUT ON RACK, FOUND ENGINE HEADS WERE FAULTY. HAD TO ORDER NEW HEADS, THEN HAD TO MACHINE HEADS WHEN ARRIVED. ALSO TRANSMISSION DOWN SHIFTED EXTREMELY HARD IN HILLS OF NORTH GA. TO THE POINT OF ENGINE RPM 4500. CONTACTED GMC COMPLAINT DEPT. BUT AS OF 6/2/15 NO HELP.

DRIVING HOME FROM LATROBE IN THE RAIN I COULD NOT SEE WITH THE LIGHTS . THE LIGHTS HAVE BLIND SPOTS IN THEM AND I HAVE HAD THEM CHANGED ONCE ALREADY. THE SERVICE DEPARTMENT SAID THEY WERE HAVING SOME PROBLEMS WITH THE LIGHTS IN THESE VEHICLES. THIS IS A REAL SAFETY HAZARD BECAUSE OF THE BLIND SPOTS WHEN DRIVING. THIS IS OCCURRING NOT ONLY IN THE RAIN BECAUSE THE NIGHT BEFORE NICE CLEAR NIGHT THE SAME SHADING COMING FROM THESE LIGHTS. THIS SHOULD NOT HAPPEN I AM SCARED TO DRIVE THIS TRUCK AT NIGHT BECAUSE OF THE HEADLIGHTS. THIS NEEDS TO BE ADDRESSED AS A SAFETY HAZARD . *TR

THIS VEHICLE HAS A 2 PHASE(LOW/HIGH BEAM) SINGLE LIGHT THAT IS EXTREMELY WEAK/DIM TO THE POINT WHERE IT IS UNSAFE TO DRIVE AT NIGHT. I CANNOT BELIEVE THAT THE EXISTING LIGHTS ARE ACCEPTABLE AND PASSED WHATEVER STANDARD/REGULATION REQUIRED. AT NIGHT, WITH THE LOW BEAMS YOU GET ABOUT 30-50FT OF LIGHT OUTPUT WHICH EQUATES TO LESS THEN A SECOND OF REACTION TIME WHEN DRIVING. THE HIGH BEAMS SIMPLY LIGHTUP ROAD SIGNS TO THE POINT OF BLINDNESS WITH IT REFLECTION BUT DOES NOT LIGHT UP THE ROAD. I TYPICALLY DON'T WRITE UNLESS I FEEL THIS IS COMPLETELY WRONG. GM WON'T ACKNOWLEDGE ANYTHING BUT IT IS ONLY A MATTER OF TIME BEFORE THERE ARE SERIOUS INJURIES AND/OR DEATH DUE DIRECTLY TO THIS PROBLEM. I AM NOW SPENDING ANOTHER $800(ON TOP OF THE $55000) I PAID FOR THIS TRUCK TO GET AFTERMARKET HID LIGHTS. CAN YOU PROVIDE FEEDBACK AS THIS HAS BEEN A CONCERN AMONGST ALL OWNERS OF THIS VEHICLE. I CAN'T BELIEVE GM IS SWEEPING THIS ISSUE UNDER THE RUG SORT OF SPEAK. I HAVE BEEN IN CONTACT WITH OWNERS WHO HAVE BEEN REFUNDED ANYWHERE BETWEEN $200-900 BUT THEY MUST SIGN CONFIDENTIALITY FORMS PRIOR TO RELEASE SO SOMETHING IS BEING HIDDEN. (PS-I LIVE IN ONTARIO CANADA...WONT LET ME INPUT CANADIAN RESIDENCE BELOW). *TR

AT HIGHWAY SPEEDS THE VEHICLE LOW BEAM HEADLIGHTS DO NOT PROVIDE SUFFICIENT ILLUMINATION TO OPERATE IN A SAFE MANNER. THIS LACK OF LIGHTING RESULTS IN AN AVOIDABLY UNSAFE PRACTICE OF OVERDRIVING THE HEADLIGHTS. THE HEADLIGHTS SHOULD ILLUMINATE FAR ENOUGH IN FRONT SO THAT IS NOT POSSIBLE TO OVERDRIVE YOUR LIGHTS AT NORMAL HIGHWAY SPEEDS. *TR

OPERATED TRUCK FOR THE FIRST TIME IN A RURAL AREA AT NIGHT YESTERDAY. LOW BEAMS PROVIDE INADEQUATE LIGHT BRIGHTNESS AND REACH. NO APPROPRIATE LATERAL LIGHTING. ONCOMING TRAFFIC "WASHED OUT" MY LIGHTING. CAN NOT EXCEED 30MPH WITHOUT JEOPARDIZING SAFETY. THESE HEADLAMPS ARE DANGEROUS ON LOW BEAM. HIGH BEAMS WERE SUFFICIENT. THE LIGHTS ARE A HAZARD TO THE TRAVELING PUBLIC AT LARGE. *TR

TL*THE CONTACT OWNS A 2015 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE HEADLIGHTS FAILED TO ACTIVATE. AS A RESULT, THE CONTACT'S VISIBILITY WAS DIMINISHED. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN STATED THAT THE HEADLIGHTS WERE FUNCTIONING AS DESIGNED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 420.

I HAD MADE A COMPLAINT TO CHAPDELAINE BUICK- GMC THAT MY BRAND NEW TRUCK DID NOT SEEM TO GO INTO FOUR WHEEL DRIVE. I WAS TOLD TO BRING THE TRUCK TO THE DEALERSHIP AND THEY WOULD CHECK IT FOR ME. I WAS TOLD BY THE SERVICE DEPARTMENT THAT THE TRUCK WORKED JUST FINE IN FOUR WHEEL DRIVE. I THEN NOTICED THAT THE TRUCK SEEM TO SHIFT VERY ROUGH AND I CALLED THE SERVICE DEPARTMENT AND TOLD THEM THAT SOMETHING HAD TO BE WRONG. THE SERVICE DEPARTMENT ASKED ME TO BRING THE TRUCK BACK DOWN TO THEM THE NEXT DAY AND THEY WOULD TAKE IT FOR A TEST DRIVE. WHILE I WAS DRIVING THE TRUCK TO THE DEALERSHIP IT SHIFTED FROM DRIVE INTO NEUTRAL.I COASTED TO A STOP PUT THE VEHICLE INTO PARK SHUT OFF AND RESTARTED THE ENGINE AND THEN SHIFTED BACK INTO DRIVE AND TRIED TO DRIVE AGAIN. THIS TIME THE VEHICLE SERVICE ENGINE LIGHT CAME ON AND THE VEHICLE STAYED IN LOW GEAR AND WOULD NOT SHIFT INTO A HIGHER GEAR. THE BEST SPEED I COULD MAKE WAS 10 MPH. I STOPPED THE VEHICLE AND RESTARTED TWO MORE TIMES. ON THE SECOND TRY THE VEHICLE DID GO INTO DRIVE. I MADE IT TO THE DEALERSHIP AND THEY TOOK IT FOR A TEST DRIVE AND UPON THEIR RETURN GAVE ME A LOANER VEHICLE. THEY HAD TO REBUILD THE TRANSMISSION ON MY BRAND NEW TRUCK WHICH TOOK ABOUT THREE DAYS. THANKFULLY THIS EVENT TOOK PLACE ON A BACK ROAD WITH LITTLE TRAFFIC. IF IT HAD HAPPENED ON A BUSY ROAD AN ACCIDENT MIGHT HAVE OCCURRED. *TR

DURING NIGHT OPERATION WITH THE INSTRUMENT CLUSTER ADJUSTED TO PROPER BRIGHTNESS THE CENTER CONSOLE LIGHTS AND MOST NOTABLY, THE INTELLILINK SCREEN ARE DANGEROUSLY BRIGHT. THE INTELLILINK SCREEN DOES NOT HAVE AN INDEPENDENT BRIGHTNESS CONTROL FROM THE DIMMER. WHEN SET TO OFF IN AN ATTEMPT TO MITIGATE THE PROBLEM, THE INTELLILINK SCREEN REACTIVATES WITH SUBSYSTEM ADJUSTMENT, E.G. TEMPERATURE ADJUSTMENT, ABSOLUTELY DESTROYING NIGHT VISION OF THE DRIVER. IF ADJUSTING THE BRIGHTNESS LEVEL TO ACCEPTABLE FOR THE CENTER CONSOLE LIGHTING AND INTELLILINK THE INSTRUMENT CLUSTER IS SO DIM THAT IT REQUIRES UNSAFE LEVELS OF DRIVER ATTENTION TO PROCESS THE DIMLY LIT INFORMATION. DEALER VERIFIED ISSUE ON TWO SERVICE VISITS BUT UNABLE TO CORRECT PER MANUFACTURER. SAFETY COMPLAINT REGISTERED BY ME WITH GMC INFOTAINMENT CUSTOMER SUPPORT. *TR
