2015 GMC SIERRA 1500 Complaints

WHEN BRAKING AND TURNING AT LOW SPEEDS THE VEHICLE STALLS WITH SERVICE STABILITRAK WARNING.

HAVING DIFFICULTY BREAKING DURING ON AND OFF PARKING MODE IN A STATIONARY POSITION. WHEN I REVERSE OR MOVE FORWARD AFTER CHANGING TO EITHER REVERS OR DRIVE GEAR MY TRUCK SEEMS TO TAKE LONGER TO BREAK, AND ALMOST FEEL THAT I DON'T HAVE CONTROL OF THE VEHICLE. ITS KINDA SCARY TO BE HONEST NOT HAVING CONTROL OF THE BREAKS. THE BREAKS DO BETTER WHEN I'M DRIVING LIKE IN THE EXPRESSWAY WITH OUT ANY PROBLEMS. HOWEVER, WHEN I PARK IN THE HOUSE OR IN A GENERAL PARKING LOT MY TRUCK ANTILOCK SYSTEM DOESN'T SEEM TO WORK VERY WELL. I HAVE ALREADY TAKEN MY TRUCK FOR A RECALL SERVICE AT A GMC DEALER KNOWN AS LUKE FRUIA IN BROWNSVILLE TEXAS 78521 BUT DON'T SEE ANY DIFFERENCE. FEELS LIKE THEY JUST DIDN'T FIX THE PROBLEM. I ALREADY TOOK THE TRUCK TO A CERTIFIED MECHANIC AND SAID THAT THE BREAK FINE SO I THINK ITS THE ANTILOCK SYSTEM NOT WORKING. IM SCARED DRIVING THE TRUCK AND FEAR I MIGHT GET INTO A COLLISION OR CRASH DUE TO MY ANTILOCK BREAKS NOT WORKING APPROPRIATELY. TO BE HONEST, I FEEL VERY UNSAFE DRIVING THIS VEHICLE SO I HAVE BEEN USING MY TOYOTA CAR. PLEASE, NEED YOUR HELP ON THIS MATTER. THANK YOU

I BOUGHT THIS NEW ON JAN 3, 2016 ON JULY 26 26, 2019 WHILE FROM WACO TO FT. WORTH TEXAS, MY AC COMPRESSOR SEIZED AND BLEW DESTROYED THE SERPENTINE BELT. I HAD TO REPLACE THE AC COMPRESSOR AND BELT. 31,000 MILES BUT OUT OF WARRANTY. LAST WEEK I WAS DRIVING HOME FROM WORK AND FELT THE AC WAS AGAIN BLOWING HOT AIR. I TOOK IT IN AND TODAY 06/29/20 I HAVE TO REPLACE THE AC CONDENSER AS IT HAS A LEAK AT A WELD POINT. I HAVE READ DOZENS OF COMPLAINTS THAT THIS IS A KNOWN ISSUE AND DEFECT. I WILL NOW BE OUT OVER $2,000 FOR A KNOWN PROBLEM AND ISSUE. I HAVE READ THE TSB, WATCHED NEWS REPORTS AND ON-LINE FORUMS. THE TECH AT MY DEALERSHIP SAID THIS IS A SUPER COMMON PROBLEM WITH THESE VEHICLES. THAT SEEMS LIKE IT WOULD LEAD TO A RECALL. *TR

A/C CONDENSER HAD TO BE REPLACED AS IT LEAKED ALL THE FREON. MY MECHANIC SAID HE'S HAD SEVERAL OF THESE GMC SIERRAS AND CHEVY SILVERADOS AROUND THE SAME AGE WITH THE SAME PROBLEM. *TR

MY 2015 GMC SIERRA HAS THE 8 SPEED TRANSMISSION WHICH HAS BEEN AN ISSUE SINCE I HAVE OWNED THE VEHICLE. I BOUGHT THE VEHICLE USED IN THE FALL OF 2018 AND THE TRUCK/TRANNY RAN GOOD FOR ABOUT 10 MONTHS. THEN IN LATE SUMMER AND EARLY FALL OF 2019, THE TRUCK JERKING HARD SHIFTS STARTED TO APPEAR. IN OCTOBER OF 2019 I BROUGHT MY TRUCK INTO MY DEALER TO HAVE THEM LOOK AT MY TRANNY DUE TO THE REALLY HARD SHIFTS FROM 1ST TO 2ND OR 2ND TO 3RD AND VICE VERSA 3RD TO 2ND AND 2ND TO 1ST. I HAD TO PAY A $80 DIAGNOSIS FEE AND THEY REPROGRAMMED MY TRANNY AND THE ECU TO SMOOTH OUT THE SHIFTS AND NOT MAKE THE SHIFTS SO HARD. IN ALL THE SOFTWARE REPROGRAM DID GET RID OF THE HARD SHIFTS, BUT IN RETURN NOW MY VEHICLE DROVE LIKE IT HAS A 6 SPEED TRANSMISSION INSTEAD OF AN 8 SPEED. IN JUNE OF 2020 I BROUGHT MY TRUCK BACK INTO MY DEALER TO LOOK AT MY TRANNY AGAIN! NOW MY TRANNY FELT LIKE IT WAS ALWAYS "HUNTING" FOR A DIFFERENT GEAR. WHEN DRIVING ON THE INTERSTATE AT 75 MPH 1600 RPM, IF THERE WAS A LITTLE BIT OF HEAD WIND OR I STARTED TO DRIVE UP A HILL, THE TRANNY WOULD DOWNSHIFT AND RPM'S JUMP UP TO 2200 RPM TO MAKE UP FOR THE DIFFERENCE IN ROAD GRADE, SAME AS WHEN DRIVING IN TOWN UP A HILLAT 35MPH. A 8 SPEED TRANSMISSION SHOULD NOT BE DOING THAT! AT INTERSTATE SPEEDS (75 MPH) MY PASSENGER SIDE SEAT WILL SIT THERE AND JUST WIGGLE AND SHAKE BACK AND FORTH. I HAVE CHANGED OUT BALL JOINTS AND STRUTS WITH BRAND NEW ONES THINKING THAT WAS THE PROBLEM AND THE SEAT STILL WIGGLES BACK AND FORTH. WHEN DRIVING MY VEHICLE IT FEELS LIKE I AM DRIVING WITH A 6 SPEED TRANSMISSION THAN AN 8 SPEED. I HAVE READ THAT THIS SEEMS TO BE A COMMON PROBLEM IN THESE MODEL YEAR GM VEHICLES AND I FEEL GM NEEDS TO FINALLY ADDRESS THIS ISSUE ONCE AND FOR ALL AND KEEP THEIR GM CUSTOMERS SATISFIED. I DIDN'T PLAN ON BUYING A 3 YEAR OLD USED VEHICLE FOR IT TO HAVE THE ISSUES IT HAS HAD SINCE I HAVE OWNED IT. *TR

WHILE THE HEAD LIGHTS AND FOG LIGHTS ARE ON, THE RIGHT HEAD AND FOG LIGHTS ARE DIM BUT THE LEFT HEAD AND FOG LIGHTS ARE BRIGHT. ALSO THE RIGHT TURN SIGNAL SHOWS ERROR MESSAGE ON THE CLUSTER THAT THE BULB NEEDS TO BE REPLACED AND YOU CAN HEAR IT BLINKING FAST, BUT WHEN I EXIT THE VEHICLE TO INSPECT THE SIGNAL I NOTICE THAT IT IS NOT BLOWN AND IT WORKS FINE BUT I STILL GET THE ERROR MESSAGE AND THE FAST BLINKING. BOTH STATED PROBLEMS OCCUR WHILE THE VEHICLE IS STATIONARY AND WHEN THE VEHICLE IS IN MOTION. *TR

THE AIR CONDITIONING WENT OUT SUDDENLY, JUST AFTER THE WARRANTY EXPIRED. AFTER RESEARCH, THIS IS AN ISSUE KNOWN TO GM AS THEY ARE CURRENTLY SUBJECTS IN PROPOSED CLASS-ACTION LAWSUITS IN 2 STATES REGARDING THIS DEFECT. *TR

BRAKING ISSUE. WHILE TRAVELING IN A DRIVE THRU, VEHICLE BRAKE PEDAL WENT TO THE FLOOR, PULSATED SOME, AND REQUIRED EXTREME EFFORT TO STOP. THIS OCCURRED DURING SUBSEQUENT BRAKING INCIDENTS WHILE MOVING AND STOPPING IN THE DRIVE-THRU. AFTER LEAVING, BRAKE PEDAL FELT OK. GOOGLED SYMPTOMS WHICH MATCHED MY CIRCUMSTANCES AND LISTED A RECALL. HOWEVER, THERE IS NO RECALL LISTED ON NHTSA. SEEMS A LITTLE TROUBLING AS THIS APPEARS TO AFFECT 3.4 MILLION GM VEHICLES. *TR

PICKUP HAS HAD REOCCURRING SERVICE POWER STEERING MESSAGE COME UP IN INFORMATION CENTER. TOOK TO GM AND THEY SAID IT NEEDED A NEW NEGATIVE BATTERY CABLE. BOUGHT ONE AND INSTALLED IT. STILL HAVE THE SAME PROBLEM. UPON DONG SOME SEARCHING, ITS A VERY COMMON PROBLEM AMONG CERTAIN GM VEHICLES. ONE WEEKEND THE POWER STEERING QUIT WORKING ALL TOGETHER AT 70 MPH ON A CURVE. TALK ABOUT SCARY! I CALLED GM CUSTOMER SERVICE TO ASK ABOUT COVERAGE ON THE ISSUE AND WAS DENIED BECAUSE MY VEHICLE WAS NOT ONE AFFECTED BY THE SUSPECT FAULTY PARTS. I AM VERY DISAPPOINTED IN GM'S LACK OF CARING FOR MY SAFETY IN THIS SITUATION. WILL NOT BE PURCHASING ANOTHER GM. IF THEY NO THAT THIS IS THEIR PROBLEM I TRULY BELIEVE THEY SHOULD STAND BEHIND THEIR PRODUCT AND TAKE CARE OF THEIR CUSTOMERS.
