POWER TRAIN
TRANSMISSION SURGES WHEN GAS PEDAL IS PUSHED HARD AS IN TRYING TO ENGAGE KICKDOWN OR "PASSING GEAR". SPEED IS NOT A FACTOR, IT HAPPENS AT LOW SPEED AND HIGHER SPEEDS. DEPENDING ON SPEED, TRUCK JERKS SUDDENLY AND ALMOST STALLS OUT. SOMETIMES REAR TIRES CHIRP.SEEMS SIMILAR TO THE 8 SPEED TRANSMISSION PROBLEMS LATER YEARS HAVE EXPERIENCED.

AIR BAGS
DASHBOARD IS CRACKING AROUND PASSENGER-SIDE AIRBAG. THE PLASTIC IS SHARP AND BRITTLE, AND I'M CONCERNED THAT SHARP SHARDS OF PLASTIC WOULD GO EVERYWHERE IF THE AIRBAG DEPLOYED. THIS IS AN EXTREMELY WELL-CARED FOR VEHICLE THAT COULD PASS FOR 'NEW CONDITION' OTHER THAN THIS DASHBOARD ISSUE.

FUEL/PROPULSION SYSTEM
I WAS DRIVING MY TRUCK UP A 6% PERCENT GRADE WHEN THE CHANGE FUEL FILTER SOON WARNING POPPED UP, ABOUT A MINUTE LATER THE VEHICLE STARTED TO LOSE POWER, I KEPT DRIVING TO TRY AND GET OVER THE HILL SO I COULD MAKE IT TO A REPAIR SHOP TO HAVE IT CHECKED OUT. I WAS ONLY ABLE TO MAKE IT ABOUT 2 MILES AFTER THE WARNING SHOWED UP BEFORE THE VEHICLE COMPLETELY SHUT DOWN AND WOULD NOT RESTART. (THERE WAS NOT ENOUGH ROOM ON THE SHOULDER TO PULL OVER ON MY SIDE THE ROAD SO I TRIED TO TURN ACROSS THE HIGHWAY WHERE THERE WAS AN EMERGENCY PULL OUT AND AS I DID THE TRUCK DIED SIDEWAYS RIGHT IN THE MIDDLE OF THE HIGHWAY, TAKING UP SEVERAL LANES OF TRAFFIC, FORTUNATELY THERE WAS ENOUGH INCLINE THAT I WAS ABLE TO ROLL BACKWARDS AND PULL OVER UP AGAINST THE GUARDRAIL) OF COURSE I HAD NO POWER STEERING OR POWER BRAKES SINCE THE TRUCK WAS NOT RUNNING. IT WAS A VERY DANGEROUS SITUATION! I WAS ABLE TO GET MY TRUCK TOWED TO THE LOCAL GM REPAIR SHOP WHERE THEY DETERMINED THAT THE FUEL PUMP HAD A CATASTROPHIC FAILURE AND HAD SENT ALUMINUM SHAVINGS THROUGHOUT THE ENTIRE FUEL SYSTEM. THEY SAID THE REPAIRS WOULD BE APPROXIMATELY $10,000 SO I CONTACTED GM AND DESCRIBED WHAT HAPPENED, AND THEY BASICALLY TOLD ME TO GO FLY A KITE. AFTER DOING SOME RESEARCH ONLINE IT LOOKS LIKE THERE HAS BEEN A MAJOR PROBLEM WITH GM TRUCKS WITH THE DURAMAX MOTOR FROM 2011-2016 AFTER THEY CHANGED THERE FUEL PUMP FROM THE CP3 HIGH VOLUME LOW PRESSURE PUMP TO THE CP4 HIGH PRESSURE LOW VOLUME PUMP. WHICH MEANS THE PUMP RUNS WITH LESS LUBRICATION WHICH RESULTS IN PUMP FAILURE, AND NOT JUST FAILURE BUT CATASTROPHIC FAILURE WHICH CAUSES MAJOR DAMAGE TO THE ENTIRE FUEL SYSTEM. I HAVE BEEN A LOYAL GM OWNER FOR OVER TWENTY YEARS, AND I AM EXTREMELY DISAPPOINTED THAT GM IS NOT WILLING TO MAKE IT RIGHT.

STRUCTURE:BODY
OUR GMC HAS EXPERIENCED 3 EXTERIOR DOOR HANDLE FAILURES. WE PAID TO HAVE THE 1ST BROKEN HANDLE REPAIRED AS IT WAS NOT OPERABLE FROM THE OUTSIDE. THIS MAKES FOR A DANGEROUS EVACUATION EXPERIENCE IN THE EVENT OF AN EMERGENCY. WE CHOSE A NON-DEALER REPAIR FACILITY DUE TO THE COST OF USING A DEALER. THIS REPAIR HAS HELD UP WELL. SINCE THAT INITIAL REPAIR 2 MORE EXTERIOR HANDLES HAVE BECOME INOPERABLE. IT'S ONLY A MATTER OF TIME BEFORE THE 4TH AND FINAL HANDLE FAILS. THIS VEHICLE IS NO LONGER UNDER WARRANTY. HOWEVER, IT'S ONLY VERY LIGHTLY USED AND HAS LESS THAN 60K MILES ON IT. A 75% DOOR HANDLE FAILURE RATE IS UNACCEPTABLE BY ANYONE'S STANDARD. DUE TO THE COST OF THE REPAIRS WE HAVE NOT BEEN ABLE TO FIX THESE REMAINING 2 DEFECTIVE HANDLES. GMC, BBB AND NORTH COUNTY GMC IN ESCONDIDO, CA HAVE BEEN OF NO ASSISTANCE. WE ARE ALWAYS PREPARED TO PERFORM THE REQUIRED MAINTENANCE ON OUR VEHICLES. IN NO WAY IS THE REPAIR OF 3 DOOR HANDLES A "NORMAL" MAINTENANCE ITEM. THIS IS A SEVERE SAFETY HAZARD IN THE EVENT THE AN EMERGENCY EVACUATION IS REQUIRED. THERE IS NO WAY FOR 2 OF THE DOORS CAN BE OPENED FROM THE EXTERIOR OF THE VEHICLE. IT'S UNFORTUNATE GMC SEES THIS AS "DEFECTIVE" BUT IS NOT WILLING TO ASSIST IN THE REPAIRS. ALL 3 OF THE HANDLE BROKE WHILE TRYING TO GAIN ACCESS TO THE VEHICLE FROM THE OUTSIDE. THE VEHICLE WAS STATIONARY EACH TIME. ALL HANDLES ARE USABLE FROM THE INTERIOR OF THE VEHICLE. THE 2 UNREPAIRED HANDLES DO NOT WORK FROM THE EXTERIOR. WE WANT TO FIX THEM AND WOULD LIKE ASSISTANCE IN DOING SO.

FUEL/PROPULSION SYSTEM
DRIVING EAST BOUND ON I70 COMING INTO DENVER. TRUCK SHUT OFF WITH NO WARNING AT 80MPH ON STEEP DOWNHILL GRADE CAUSING LOSS OF ALL POWER FACILITIES IN THE TRUCK. NO BRAKES, NO POWER STEERING. I ENDANGERED THE LIVES OF EVERY SINGLE PERSON ON THE ROAD THANKS TO THIS FAILED FUEL PUMP. FURTHER INVESTIGATION SHOWS BOSCH (THE PUMP MANUFACTURER) HAD INSTRUCTED GM TO USE A LIFT PUMP ON THIS ITEM AND THEY HAVE DISREGARDED THAT RECOMMENDATION LEAVING PEOPLE IN DANGER OF SERIOUS INJURY OR DEATH. THIS ITEM NEEDS A RECALL AND GM IS REFUSING TO DO SO BECAUSE THIS OCCURRENCE RENDERS THE TRUCK IN NEED OF 13K+ I'M REPAIRS. SHAME ON GM AND SHAME ON NHTSA FOR NOT DOING THEIR JOB.

FUEL/PROPULSION SYSTEM
I HAVE BEEN SMELLING A STRONG ODOR OF GAS COMING THRU MY AIR VENTS WHILE MY VEHICLE IS RUNNING, PARTICULARLY WHILE I AM IDLING AND JUST AFTER ACCELERATION. MY MECHANIC STATED HE HAS REPAIRED SEVERAL OF THESE ISSUES ON OTHER GMC'S. THE PROBLEM IS THE TOP OF THE FUEL TANK IS RUSTED WHERE THE FUEL PUMP IS LOCATED AND GAS SPRAYS UPWARDS ONTO THE BOTTOM SIDE OF THE BED AND IS VERY COSTLY AND DIFFICULT TO REPAIR. I'M SURE GM IS AWARE OF THE PROBLEM, HOWEVER, THEY HAVE CHOSEN TO IGNORE THE ISSUE. THIS IS MOST DEFINITELY A SAFETY ISSUE!
