ENGINE
I have noticed over the last few weeks I am losing radiator fluid. Its slow but noticeable. Engine temperature rises and fan stays on. My 2015 GMC Sierra 1500 only has 50,150 miles on it, and started well under 50,000. It looks like the leak is from upper contact points of Radiator and frame. I have come to find out that GMC has put a notice out on this issue and put a recall/repair out on the 2014 GMC Sierra 1500 for the same issue. Its a know defect. ( I WILL ATTACH COPIES ) I went to the dealer and was told they would fix the 2014 but have not issued a fix for the 2015. "Not enough complaints"? Its a very expensive fix for a KNOWN manufactured defect but GMC (AND CHEVY TRUCKS) want more complaints.... so here is my filing. Kind of a silly game they are playing when they know it should be a recall issue.

ENGINE
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.

SERVICE BRAKES
Whenever I connect a trailer to my vehicle I will lose all brake pressure when in reverse. It only happens when in reverse and connected to a trailer. I will have to pump my brakes to the floor and there's no braking power. This does not happen when I do not have a trailer connected.

ELECTRICAL SYSTEM, SERVICE BRAKES, UNKNOWN OR OTHER
I was towing a camper down Rt 422 in Butler, PA in my GMC truck when it suddenly caught fire. My wife was following me and alerted me to pull over as quickly as possible. I had no brakes and the gear shifter went straight up without shifting. The doors would also not open while the truck was filling with smoke. I got out using the manual unlock knob and am lucky to be alive. We had about one minute to try to extinguish the flames before it fully engulfed both my truck and camper. I filed a complaint with GMC. By what I am reading online there are many instances of fires and GMC does not seem to provide assistance. This is very unnerving and scary to say the least. I am sad and angry for this situation. This happened through no fault of my own and I lost absolutely everything. I was in the middle of moving to start a new job and lost many work items in my truck as well. I had to delay my start date for work. Now I am responsible for deductables, insurance increases and other items not covered by my insurance. Now I have to buy a new vehicle and camper but what will GMC do to help me? Probably nothing.

EXTERIOR LIGHTING
THE HEADLAMPS ON MY VEHICLE HAVE BEEN VERY POOR, BOTH IN LOW AND HIGH BEAM POSITIONS EVER SINCE I PURCHASED THE VEHICLE. THINKING THAT THEIR MUST BE SOMETHING WRONG WITH THE EXISTING HEADLAMPS, I PURCHASED THE REPLACEMENT BULBS AND THERE WERE NO IMPROVEMENTS. WHEN DRIVING AT NIGHT I HAVE TO STAY ON LOW BEAM WITH THE FOG LIGHTS ON JUST TO HELP TO SEE. I CAN'T USE MY HIGH BEAMS AT ALL BECAUSE THE LIGHTING IS SO POOR. GMC IS AWARE OF THEIR HEADLAMP ISSUES ON THE 2014 AND 15 MODELS BUT NOTHING IS BEING DONE ABOUT IT TO MY KNOWLEDGE. WITHOUT SPENDING $500-$1000 TO CHANGE THEM OVER TO LED, IS THERE ANYTHING THAT I CAN DO TO IMPROVE THIS SITUATION?

FUEL/PROPULSION SYSTEM
I SEE THERE WAS A RECALL FROM GM #17399 FOR THE 2015 DUAL FUEL TANK SENDING UNIT PROBLEM. THIS IS ONLY FOR THE 6.0 L GAS ENGINE. I HAVE THE DURAMAX 6.6L ENGINE IN MINE. I HAD THE SAME PROBLEM WITH MINE. THE SENDING UNIT DID NOT TURN OFF THE TRANSFER PUMP AND OVERFILLED THE FRONT TANK CAUSING FUEL TO POUR OUT ALL OVER THE ROAD. I CAUGHT IT BEFORE THE DRIVE LINE CAUSED ANY DAMAGE. I HAD IT TOWED TO THE DEALER AND WHILE WE MOVED IT TO PULL IT UP ON THE TOW TRUCK IT WAS PUSHING FUEL OUT OF THE FILLER NECK OF THE FRONT TANK. THE DEALER SHIP REFUSED TO COVER THE COST SAYING ITS NOT PART OF THE RECALL. THEY SAID IT WASN'T THE SAME PROBLEM. IT SURE WAS. I HAVE ATTACHED THE REPAIR ORDER AND THE RECALL NOTIFICATION BELOW. I AM WONDERING IF IT IS PART OF THE RECALL AND THEY ARE JUST NOT DOING THEIR JOB AND HONERING IT.

RADIATOR FORMS STRESS CRACKS FROM CONSTANT THERMOSTAT CYCLING. THE RESULTING CRACKS CAUSE THE RADIATOR TO LEAK. GM HAS ISSUED SPECIAL COVERAGES FOR CERTAIN MODELS BUT DOESN'T ACKNOWLEDGE IT IS A VERY COMMON PROBLEM ON OTHER MODELS OUTSIDE THE COVERAGE.

I TOOK VEHICLE TO DEALER FOR TEST DRIVE FOR TRADE IN PURPOSES AND WAS INFORMED THAT MY RADIATOR LEAKED AND IT WAS A PROBLEM WITH 2015 GMC SIERRA AND NEEDED REPLACING FOR $1400. THERE IS A RECALL FOR SAME PROBLEM WITH 2014 YEAR BUT NOT 2015 AND THIS SHOULD BE CORRECTED BECAUSE IT IS A KNOWN DEFECT AND CONSUMER SHOULD NOT HAVE TO PAY FOR DEFECTIVE PART.

UNKNOWN OR OTHER
WHILE DRIVING, A MESSAGE POPS UP ON THE DISPLAY THAT READS: "WARNING TAKING YOUR EYES OFF THE ROAD TOO LONG, OR TOO OFTEN WHILE USING THIS SYSTEM COULD CAUSE A CRASH, RESULTING IN INJURY OR DEATH TO YOU OR OTHERS. FOCUS YOUR ATTENTION ON DRIVING" SERIOUSLY, WHEN A WARNING MESSAGE POPS UP, WE READ IT! I HAVE GOTTEN USE TO THIS STUPIDITY AND JUST HIT OK. BUT EVEN AT THAT, YOU STILL GET DISTRACTED. PROBLEM NOW, IS THAT EVEN HITTING OK DOES NOT CLEAR IT. THIS MESSAGE SHOULD NEVER HAPPEN. I HAVE READ THAT THIS A BIG ISSUE AMONG MANY GMC AND CHEVY OWNERS. GM IS LITERALLY CREATING THE SAFETY HAZARD.

AFTER SOME RAIN, THE PAINT JUST FELL OFF THE VEHICLE. GM REFUSES TO ASSIST IN REPAIRING. FOR THE COST OF THE VEHICLE THIS IS ABSOLUTELY A MAJOR ISSUE.
