POWER TRAIN
PURCHASED VEHICLE BRAND NEW FROM DEALERSHIP AND FROM DAY ONE, I NOTICE THE POWER TRAIN SLOW TO SHIFTING FROM GEAR ONE TO TWO. THE VEHICLE HESITATES AND SOMETIMES SHIFTS HARD ONLY DURING COLD STARTS. EVERY TIME I TAKE IT IN FOR MY SCHEDULE SERVICE I REPORT THE SAME ISSUE TO MY SERVICE ADVISOR ALONG WITH THE SERVICE MANAGER AT THE GMC DEALERSHIP. THEY SAY THAT IT IS A NORMAL PROBLEM AND THEY KNOW ABOUT IT. THE LAST SCHEDULE SERVICE I TOLD THEM ABOUT THE SAME PROBLEM, THIS TIME HIS SERVICE TECH TEST DROVE VEHICLE AND SAID TORQUE CONVERTER WAS SHUDDERING CAUSING VIBRATION. THE SOLUTION HE SAID THEY CHANGED THE TRANSMISSION FLUID. TODAY I STILL NOTICE THE SAME ISSUE AND WILL REPORT TO THE DEALERSHIP NEXT TIME I TAKE IN FOR SERVICE. I HAVE READ THIS IS A COMMON PROBLEM FROM THE MANUFACTURE SINCE PUTTING IN AN 8 SPEED TRANSMISSION. I FEEL THIS IS A SAFETY ISSUE AND SOME DAY I MAY FEEL THAT THE TRANSMISSION MAY LOCK UP ON ME AND MAY CAUSE AN ACCIDENT. *TR

WHILE GETTING MY TRUCK INSPECTED THE SHOP OWNER TOLD ME ABOUT A BULGE ON RIGHT FRONT TIRE. HE ASKED ME IF THEY SOLD THAT TO ME LIKE THAT I PROCEEDED TO TELL HIM YES. HE SAID IT SHOULD BE REPORTED SO THAT IS WHAT I'M DOING. I'M NOT SURE IF THIS IS COVERED. I CONSIDERED IT A SAFETY WHEN VEHICLE WAS PURCHASED IN TENNESSEE AND GOING TO UPSTATE NY, AND I'M 74 YRS OLD.

POWER TRAIN
WHEN TRUCK IS IN MOTION SHIFTING FROM REVERSE TO FIRST/SECOND GEAR IT JUMPS FORWARD INTO GEAR. THERE IS A HESITATION SHIFTING INTO GEAR. IT IS A VERY WELL KNOWN PROBLEM WITH THE 8 SPEED TRANSMISSION. I HAVE BEEN IN CONTACT WITH THE DEALER BUT 3 DIFFERENT TIMES. THE KNOW THE PROBLEM AS DOES GMC. THEY ACTUALLY CAN FIX THE PROBLEM. BUT WILL NOT DO ANYTHING UNTIL GMC SENDS OUT A TECHNICAL BULLETIN. THERE HAS BEEN AN UNBELIEVABLE AMOUNT OF COMPLAINTS. I UNDERSTAND GMC IS HESITANT BECAUSE THEY MAY HAVE TO REPLACE TRANSMISSION AND OR TORQUE CONVERTER WHICH WOULD NATURALLY COST A LOT OF MONEY. BUT ALSO I UNDERSTAND CHANGING TO A DIFFERENT TRANSMISSION FLUID WILL HELP. BUT DEALER WILL NOT DO IT. THIS HAS BEEN GOING ON SINCE THE DAY I BOUGHT IT BRAND NEW AND I ONLY HAVE 5700 MILES ON IT. I HAVE NOT HAD ACCIDENT BECAUSE OF THIS. BUT CONCERNS ME WITH THE HESITATION AND JUMPING IN TO GEAR. ALSO IT DOES NOT DO IT EVERY SINGLE TIME. DEPENDS ON YOUR TAKE OFF SPEED. *TR

SERVICE BRAKES
APRIL 9TH 2020 I WAS OPERATING MY VEHICLE A 2018 GMC SIERRA 3500 DENALI EQUIPPED WITH THE DIESEL PACKAGE. I WAS TOWING A BOBCAT SKID STEER ON A TRAILER WITH A TOTAL WEIGHT OF APPROXIMATELY 4300LBS. I WAS TRAVELING AT ABOUT 45 MPH WHEN I ENCOUNTERED A RED LIGHT. WITH PLENTY OF ROOM TO STOP I APPLIED THE BRAKES AS NORMAL. THEY INITAILLAY GRABBED AND SLOW MY TRAVEL TO ABOUT 40 MPH. THEN OUT OF WHAT SEEMED NOWHERE THE BRAKE PEDAL RAPIDLY WENT TO THE FLOOR AND THE VEHICLE FREEWHEELED THROUGH THE LIGHT. I ATTEMPTED MULTIPLE TIMES TO EASE OFF THE PEDAL AND REAPPLY TO NO AVAIL. UPON ENTERING THE INTERSECTION I NEARLY CRASHED INTO A VEHICLE. WHEN I NEARLY I MEAN WITH INCHES. I IMMEDIATELY SLAMMED THE E-BRAKE BRINGING THE TRUCK TO A SKIDDDING HALT. AFTER DROPPING THE TRAILER OFF IN AN EMPTY PARKING LOT MY VEHICLE WENT TO MY LOCAL DEALER. THE SERVICE ADVISER WHO 1ST ENCOUNTERED THE VEHICLE EXPERIENCED THE ISSUE 1ST HAND.AFTER HAVING IT FOR NEARLY A WEEK THEY CALLED TODAY TO SAY 'THEY CAN'T FIND THE ANY ISSUES'. THAT MAKES THIS SITUATION EVEN MORE DANGEROUS. YOU'RE UNAWARE WHEN THIS CAN HAPPEN. THESE VEHICLES NEED TO HAVE A NEW RECALL IMMEDIATELY

ELECTRICAL SYSTEM
MY 2018 GMC SIERRA HD EXPERIENCED AN ELECTRICAL SHORT OR OVERLOAD, CAUSING A THERMAL EVENT THAT MELTED AREAS AROUND THE REAR DEFROST CIRCUIT. LOTS OF SMOKE AND BURNING SMELL, BUT LUCKILY, I DID NOT SEE FLAMES. THE EXACT ISSUE IS CURRENTLY BEING ADDRESSED UNDER GM RECALL# "N192265660 REAR WINDOW DEFROSTER THERMAL EVENTS", HOWEVER MY VIN IS NOT INCLUDED. THE ISSUE I HAD IS EXACTLY WHAT IS DESCRIBED AND I BELIEVE SHOULD BE INCLUDED IN THE RECALL. I'VE ATTACHED A FEW IMAGES OF THE BURNED, MELTED AND BROKEN PARTS. AGAIN, I'M LUCKY THERE WAS ONLY SMOKE WHEN THIS HAPPENED, AND NO FIRE. PLEASE REVIEW AND ADVISE
