EXTERIOR LIGHTING
THE 3RD BRAKE LIGHT ALLOWED RAIN TO ENTER THE CAB OF TRUCK.(GASKET FAILED) HEADLINER, CARPET ON FLOOR, INSULATION ALL RUINED. DIAGNOSED BY A "WATER DOCTOR" AT THE DEALER WHERE TRUCK WAS PURCHASED. THE FLOOR ON THE PASSENGER FRONT WAS SOAKED, HEADLINER IS STAINED. I REMOVED ALL SEATS, CARPET, INSULATION AND THE SMELL IS STILL THERE. CALLED GMC TO TRY TO GET ASSISTANCE ON REPAIRS. TRUCK IS OUT OF FACTORY WARRANTY. GMC OFFERED $585 LEAVING A BALANCE OF $1300 TO BE PAID BY ME TO REPLACE THE HEADLINER. HOW IS IT THAT THE 3RD BRAKE LIGHT ALLOWS RAIN TO ENTER THE CAB OF THE VEHICLE. ITEMIZED ESTIMATE FROM DEALER TO REPLACE AND PUT TRUCK BACK TOGETHER IS $4500-$5000. MONEY THAT I DON'T HAVE. THIS IS A POOR DESIGN. DID NOT KNOW/REALIZE THAT A GASKET WOULD FAIL AND ALLOW WATER TO LEAK INSIDE. THE TRUCK IS PARKED IN OUR DRIVEWAY OR ON THE STREET. I DO NOT HAVE A GARAGE. I STARTED TAKING THE SEATS AND CARPET OUT THE LAST WEEK OF DECEMBER 2020. OVER THE NEXT FEW WEEKS INSULATION WAS REMOVED. THE MOLDY/MUSTY SMELL REMAINS. GMC WAS CONTACTED APPROXIMATELY THE LAST OF JANUARY OR THE FIRST WEEK OF FEBRUARY 2021. I AM STILL IN TALKS WITH THEM. AARON, CASE MANAGER AT GMC WITH WHOM I HAVE BEEN DEALING. HE IS TRYING TO FIGURE OUT SOMEWAY TO GIVE ME ASSISTANCE IN GETTING MY TRUCK BACK TOGETHER. I DON'T KNOW HOW LONG IT HAS BEEN LEAKING BEFORE I STARTED SMELLING THE MUSTY ODOR.

SERVICE BRAKES
MY BRAKE ASSIST SERVICE LIGHT CAME ON IN MY TRUCK AND THE BRAKES ARE ACTING WEIRD AT LOW SPEEDS. I KNOW THERE IS ALREADY A RECALL FOR THIS IN 2015 GMC SIERRA'S BUT APPARENTLY MINE ISN'T INCLUDED. THIS IS APPARENTLY A PROBLEM FOR ALL 2015 GMC'S SO HOW DO I GET MINE INCLUDED. I ALREADY CONTACTED MY LOCAL GM DEALER AND THEY WON'T DO ANYTHING ABOUT IT UNLESS I PAY FOR IT. IT'S OBVIOUSLY A KNOWN PROBLEM AND A BIGGER PROBLEM THAN THEY ARE ADMITTING. HELP ME GET ALL 2015 GMC ON THE RECALL LIST BEFORE SOMEONE ELSE GETS HURT OR KILLED

ELECTRICAL SYSTEM
I HAVE HAD THE VEHICLE FOR ALMOST 5 YEARS AND HAVE NEVER HAD AN ISSUE RUNNING THE REAR DEFROSTER OR REMOTE STARTING THE VEHICLE. IN JAN OF 2020, THE VEHICLE WAS RECALLED FOR REAR WINDOW DEFROSTER THERMAL EVENT (N192265660). I HAD THE RECALL COMPLETED ON 6/18/20 (SEE ATTACHED WORK ORDER). ON 02/11/21 I WAS RUNNING THE REAR DEFROSTER AND HEARD A CRACKLING SOUND. I TURNED OFF THE DEFROSTER AND EVERYTHING APPEARED NORMAL. ON 02/13/21 I REMOTE STARTED THE VEHICLE TO LET IT WARM UP (VEHICLE WAS STATIONARY). UPON ENTRY OF THE INTO THE VEHICLE I SMELLED WHAT APPEARED TO BE BURNING WIRES. A FEW MOMENTS LATER THE GLASS ON THE REAR WINDOW SHATTERED (SEE PICTURES). I LOOKED DOWN AND NOTICED THAT THE REAR DEFROSTER WAS RUNNING AS EXPECTED FOLLOWING A REMOTE START. I IMMEDIATELY TURNED THE REAR DEFROSTER OFF. MY CONCERN IS THAT FOR YEARS I RAN THIS DEFROSTER WITH NO ISSUE. I DID MY DUE DILIGENCE TO COMPLETE THE RECALL IN A TIMELY MANNER TO PREVENT ANY THERMAL EVENT FROM OCCURRING. IT APPEARS THAT EITHER THE RECALL WAS NOT COMPLETED CORRECTLY, OR THE RECALL FIX CREATED A NEW THERMAL EVENT. THE BURNING WIRES AND SHATTERING GLASS WERE A FEW OF THE INDICATORS IN THE ORIGINAL RECALL. I PLAN TO CONTACT GM FOR A WAY AHEAD.

FUEL/PROPULSION SYSTEM
2015 GMC SIERRA 2500 DURAMAX DRIVING EAST WITH THE FLOW OF TRAFFIC ON 80 REACHING THE SUMMIT TOWARDS TAHOE. WE SUDDENLY EXPERIENCE AT "CHANGE FUEL FILTER" WARNING WHICH ONLY LASTED APPROXIMATELY 20 SECONDS BEFORE THE MESSAGE THEN READ "DERATING". UPON THIS SECOND NOTIFICATION WE IMMEDIATELY LOST POWER TO THE ENGINE WHICH RESULTED IN REDUCED BRAKING CAPABILITY AND STEERING AT LITERALLY THE TOP OF THE MOUNTAIN. WE WERE TRAVELING IN SNOWY CONDITIONS WITH MANY SEMI TRUCKS AROUND US. WE TRIED TO SAFELY DRIFT TO THE SHOULDER TO THE SAFEST POSSIBLE PLACE. THE SUDDEN LACK OF POWER LEFT MY FAMILY, INCLUDING 3 CHILDREN, IN A VERY DANGEROUS POSITION. WE ENDED UP BEING STRANDED WITH TOW TRUCKS BEING VERY SCARCE AND CHALLENGING TO FIND. THE NEAREST RENTAL CAR TOOK 2 HOURS TO GET TO, AND WE HAD TO SHUFFLE KIDS ALL OVER. ONE CHILD WAS CRYING AND SCARED TO DEATH AT ALL THE CARS ZOOMING BY AND OUR INABILITY TO MOVE. IT APPEARS THAT THE CP4 FUEL PUMP MAY HAVE FAILED LEAVING US ALMOST INSTANTANEOUSLY IN AN UNSAFE SITUATION.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
REAR WINDOW DEFROSTER STARTED SMOKING AND CREATED A BURNING PLASTIC SMELL. AFTER TURNING OFF THE REAR DEFROSTER THE REAR WINDOW EXPLODED/SHATTERED IN PLACE. I SEE THERE IS A RECALL IN CANADA, BUT NOT HERE. THIS IS HAPPENING HERE AND I HAVE READ OF MANY OTHERS WITH SAME ISSUE. FIRE AND BROKEN GLASS IS NOT SAFE AND SHOULD BE ADDRESSED

IT HAS A PROBLEM WITH CYCLING OF THE THERMOSTAT THAT CAUSES STRESS FRACTURES ON THE RADIATOR LEADING TO COOLANT LEAKS. ATTACHED ARE GM BULLETINS ON THE 2014 AND 2015 MODELS. AS ONE CAN SEE THEY HAVE PROVIDED SPECIAL COVERAGE. MY RADIATOR IS LEAKING JUST LIKE THE SERVICE BULLETIN SAYS. THIS NEEDS TO BE RECALL.

ELECTRICAL SYSTEM, VISIBILITY/WIPER, UNKNOWN OR OTHER
VEHICLE WAS STATIONARY ON THE STREET, PARKED. I ENTERED IT, AND TURNED ON MY FRONT AND REAR DEFROSTERS WITH THE SETTING ON "HI." I TURNED AROUND AND VERIFIED THAT MY VEHICLE HAD NOT BEEN HIT NOR WAS ANY DAMAGE AT ALL APPARENT TO ME. AT SOME POINT AS I SAT THERE WITH THE CAR IDLED AND THE HEATED AIR REACHING ITS MAXIMUM TEMPERATURE, I BEGAN TO SMELL SOME FOUL SMELL IN THE CAB THAT I BELIEVED WAS EXHAUST ENTERING THE CABIN. I ROLLED DOWN THE WINDOW. AS I BRUSHED THE SNOW FROM THE FRONT AND BEGAN TO DRIVE AWAY, I HEARD A NOISE THAT I BELIEVED WAS THE SNOW FALLING FROM THE ROOF. HOWEVER, AS I ROLLED AWAY, I NOTICED A LOUDER-THAN-NORMAL CABIN. UPON LOOKING BEHIND ME, I NOTICED THE REAR RIGHT WINDOW WITHIN THE SLIDING REAR CABIN WINDOW HAD BLOWN OUT. UPON INSPECTING THE AREA, I NOTICED THAT NO SNOW OR WATER WAS PRESENT INSIDE. GIVEN THAT WE HAD RECEIVED A LOT OF SNOW THE PREVIOUS EVENING THROUGH THE MORNING, HAD THE DAMAGE OCCURRED THROUGHOUT THE EVENING OR EARLY MORNING, THERE WOULD'VE BEEN MOISTURE PRESENT.

SERVICE BRAKES
4 MONTHS AGO THE DISPLAY PORTRAYED A MESSAGE STATING, TRAILER BRAKE WARNING, HAVE SYSTEM CHECKED. SINCE THAT TIME I HAVE ATTEMPTED ON NUMEROUS TO HAVE MY VEHICLE CHECKED. BUT AS OF THIS DATE I HAVE NOT BEEN TO HAVE ANY DEALERSHIP LOOK AT MY VEHICLE. I HAVE BEEN TOLD BY DEALERSHIP THAT THE VEHICLE COMPUTER SHOWS A HISTORY BUT NO CURRENT ERROR CODES, AND THEY CAN NOT WORK ON VEHICLE UNTIL IT HAS CURRENT CODES. SO I HAVE A TRUCK THAT IS DESIGNED TO TOW CARGO/VEHICLE BUT I AM NOT ABLE TO USE MY TRUCK FOR THAT PURPOSE BECAUSE OF THIS WARNING MESSAGE. I HAVE CONTACTED DEALERSHIPS, CUSTOMER SERVICE WITH GMC AND EVEN FILED A COMPLAINT WITH TENNESSEE DEPT OF CONSUMER AFFAIRS, BUT NO ONE WANTS TO HELP WITH MY PROBLEM. I HAVE NOTICED ON THE INTERNET THAT I AM NOT THE ONLY ONE WITH THIS ISSUE. DANGEROUS SITUATION SHOULD SOMEONE USE VEHICLE TOWING. BIGGEST PROBLEM GM DOES NOT WANT TO EVEN ACKNOWLEDGE THAT THEY HAVE A PROBLEM.
