Water intrusion from antenna ran down into my wires causing corrosion in my electrical harness. Truck will throw code p2138 and go into reduced power mode. Very dangerous when you are in traffic. Truck will not go over 15mph when this happens. This has been a problem intermittently since I have owned the truck at 119000 miles . Gotten progressively worse.

I was driving down the road after turning on the rear window defrost. The cab of the truck filled with smoke billowing from the back seat. I pulled over and turned the truck off. I got into the back seat to try to identify what was on fire, and noticed the lines of the rear window defrost system were actually smoldering. Then one of the rear windshield panels exploded in my face. Upon reading online, it looks like a recall was issued for this same problem in Canada but not the USA.

While driving to work with my workers and I on HWY going 70 mph pickup just turned off on me and no longer started up. Took to Mechanic and said it was the Bosch CP4 failure. Metal debris flooded our entire high-pressure fuel system. Had to get replacement of fuel lines, fuel rails, pump and injectors and the removal/flushing of the fuel tank. Our total repair is over $12,000. which we don't have. Mechanic just finished repairing it after 11 month's but we don't have the $ to get it out from shop.

I turned on my rear defroster. I smelled electrical burning and rear window shattered with my 6 month old in the back seat in her car seat. GM states there is a recall which can be referenced as N192220470. Speaking with customer service and dealership the recall is VIN specific and my vehicle is not included in the recall even though the year and make is listed in the recall. Very dangerous, especially when there are passengers in the back seat of the vehicle

The display of the intellink system acts erratic and eventually freezes up. It happens in all modes ( map, radio, phone, ….). The only way to reset is shut the truck off. GMC knows of the problem but their only solution is replace the radio and or replace the touch panel. This can be a safety issue but I take my eyes off the road to try and get the display to work.

I was driving at approximately 40 MPH on a busy city street, I was going to be getting on the freeway where my speed would be in excess of 70MPH. Suddenly without any warning, my 2015 GMC Sierra 2500 HD Duramax died. I had no power at all which means no steering, brakes, etc. I was able to get the vehicle off the road with brute force. After the vehicle was towed to the dealership they inspected it and said that the Fuel Injector Pump failed which put metal throughout the whole fuel injection system (>$7000 repair). While doing some additional research on the Internet I find out that this is a common problem for the 2011-2016 GM Duramax trucks, because GM chose to use a Bosch Fuel Injector Pump which is not suitable for use with US low sulphur diesel fuel.

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.

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.

THIS IS AN ISSUE WITH A SAFETY FEATURE AND IT SHOULD BE REPLACED/FIXED AT YOUR EXPENSE.
