2015 GMC SIERRA 2500 Complaints

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.

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.

THE POWER STEERING GOES OUT WHEN TURNING. THIS IS HAPPENING MORE AND MORE FREQUENTLY. 2014 GMC TRUCKS HAVE A RECALL (#14743) ADDRESSING THIS POWER STEERING ASSIST ISSUE. GMC SAID THAT I NEED TO GET IT FIXED AT MY COST.

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.

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.

GMC, I AM EMAILING YOU IN REGARDS TO SAFETY FEATURES OF OUR 2015 GMC SIERRA DENALI NOT WORKING PROPERLY. THE REAR SEAT BELTS DO NOT LOCK AND THEY DO NOT RETRACT WITHOUT ASSISTANCE. WE ASKED THE DEALERSHIP LOCALLY IF IT IS RECALL RELATED ISSUE AND THEY SAID WE WOULD HAVE TO PAY TO HAVE THEM FIXED. THIS IS AN ISSUE WITH A SAFETY FEATURE AND IT SHOULD BE REPLACED/FIXED AT YOUR EXPENSE. WE HAVE FAMILY FRIENDS WHO WERE INVOLVED IN A COLLISION ON I70 WITH A BEAR, IN A GMC OR CHEVY AND THEIR LITTLE BOY ALMOST DIED BECAUSE HIS SEAT BELT FAULTED TO LOCK AND KEEP HIM SAFE. SINCE KNOWING THAT WAS A HUGE ISSUE, IT IS IMPORTANT TO US TO PURSUE GETTING THIS FIXED. IT HAS BEEN LIKE THIS SINCE WE BOUGHT THIS TRUCK IN 2016. WE LOOK FORWARD TO HEARING BACK FROM YOU REGARDING THIS MATTER.
