2015 GMC SIERRA 1500 Complaints

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.
