ENGINE
WHEN I WAS DRIVING MY TRUCK OFF THE HIGHWAY ONTO THE MAIN ROAD WHERE I WAS GOING I NOTICED THERE WAS AN ISSUE WITH MY TRUCK. AFTER COMING TO A STOP AT A RED LIGHT ONCE IT TURNED I ACCELERATED AND SUDDENLY FELT A JERK FROM THE TRUCK AND HEARD A LOUD WHISTLING NOISE. IT DID THIS MULTIPLE TIMES ABOUT 5-6 TIME EVERY TIME I WOULD ACCELERATE FROM A SPEED OF 30-40. I DECIDED TO DROP IT OFF AT MY LOCAL GMC TO GET IT LOOKED AT. THEY CALLED ME THE NEXT DAY TO PICK IT UP SINCE THEY RAN IT THROUGH DIAGNOSTICS AND DIDN'T FIND AN ISSUE WITH THE VEHICLE. ONCE I GOT THERE I DEMANDED FOR THE MECHANIC TO COME DRIVE THE TRUCK WITH ME TO SEE WHAT THE ISSUE WAS AND THEY DECIDED THEY NEEDED TO KEEP IT FOR A COUPLE OF DAYS TO GET IT LOOKED AT. THEY THEN CALLED TWO DAYS AFTER AND SAID THAT THE TRANSMISSION WAS MESSED UP AND NEEDED A NEW ONE TOTALING THE COST TO $5346.07 WHICH IS CERTAINLY NOT SOMETHING WE CAN AFFORD RIGHT NOW! I DON'T UNDERSTAND HOW THEY DIDN'T SEE THE ISSUE THE FIRST TIME THEY DIAGNOSED IT?? THIS IS SOMETHING THAT NEEDS TO GET RECALLED I HAVE SEEN MANY SIMILAR ISSUES.

POWER TRAIN
SINCE DAY ONE WITH MY 2015 GMC 2500 THE TRANSMISSION HAS ACTED VERY WEIRD WHEN DRIVING. EVERY APPOINTMENT I HAVE MADE FOR SERVICE AT THE DEALER I HAVE COMPLAINED ABOUT THE SHUDDERING AND INCONSISTENT UPSHIFTING AND DOWNSHIFTING AND OF COURSE THE DEALER TELLS ME THAT THEY CANNOT FIND ANYTHING. NOW IT IS TO A POINT WHERE TRANSMISSION IS SHIFTING BUT THE TRUCK HAS NO POWER SOME OF THE TIME. I FEEL LIKE IT COMES AND GOES WEEKLY. I ALSO OWN A 2015 GMC 3500 THAT I BOUGHT AT THE SAME TIME BUT THAT TRUCK RESEMBLES NONE OF THESE SYMPTOMS.

SERVICE BRAKES, ELECTRONIC STABILITY CONTROL (ESC), ENGINE
THE VEHICLE IS STALLING WHEN BRAKING AND GETTING READY TO TURN. MY TRUCK IS SHOWING STABILITRAK SERVICE INTERMITTENTLY AND I'VE ALMOST BEEN IN A CRASH 3 TIMES BECAUSE OF THIS. THE VEHICLE ONLY RESTARTS AFTER PLACING IN PARK. THIS IS NOT SAFE WHEN IN TRAFFIC. THERE SEEMS TO BE NO RECALLS AND NO KNOWN CAUSE. SOMEONE IS GOING TO DIE IF GM DOESN'T FIX THIS. I'VE BEEN ON FORUMS AND IT'S A COMMON PROBLEM. IT SHOULD BE FIXED BY GM IF IT IS SO COMMON. THIS HAPPENS WHEN APPROACHING CROSS TRAFFIC AT AN INTERSECTION AND I LOSE ALL CONTROL OF STEERING BRAKING AND POWER TO THE TRUCK.

WHILE DRIVING THE TRANSMISSION SLIPPED WHILE ATTEMPTING TO CHANGE GEARS. THIS CAUSED THE VEHICLE TO BE UNRESPONSIVE AND INDICATE A PROBLEM ACCELERATING. THIS HAS BEEN GETTING WORSE OVER THE PAST SEVERAL MONTHS AND ENDED UP LEAVING ME IN A VERY DANGEROUS SITUATION YESTERDAY WHILE DRIVING.

SERVICE BRAKES
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

SERVICE BRAKES
I WAS DRIVING IN MY CITY AND THE BRAKES WERE FINE PRIOR. I WAS COMING UP TO A STOP SIGN AND ALL OF THE SUDDEN MY BRAKE PEDAL WAS GOING TO THE FLOOR. I COULD NOT STOP WITHIN REASON. LUCKILY NO ONE WAS IN THE CROSSWALK OR I WOULD HAVE HIT THEM. I USED THE E-BRAKE AND MY EXHAUST BRAKE TO HELP SO ME SLOW DOWN. I WAS DOING ABOUT 35MPH. I TOOK THE TRUCK HOME IMMEDIATELY AS SAFE AS I COULD. I CALLED THE GM DEALERSHIP BY ME AND TOOK IT TO THEM. THEY ARE ONLY A FEW MILES AWAY AND I TOOK BACK ROADS TO AVOID TROUBLE. I WAS INFORMED BY THE GM DEALERSHIP THAT THERE WAS AN INTERNAL FAILURE OF THE BRAKE BOOSTER AND MASTER CYLINDER. $654.00 DOLLARS TO REPAIR MY 2500 DENALI TRUCK. I CALLED GM SERVICE ALREADY AND THEY INFORMED ME MY TRUCK WAS NOT UNDER THE RECALL. THIS ISSUE OBVIOUSLY EXISTS TO MORE VEHICLES THAN WHAT THEY SPECIFY AND YOU COULD LOSE BRAKES AT ANY MOMENT. GM NEEDS TO RECTIFY THEIR TRUCK BRAKE SITUATION. SOMEONE WILL END UP GETTING KILLED.

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

POWER TRAIN
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

EXTERIOR LIGHTING
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

SERVICE BRAKES
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

STEERING
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.
