What 59 owners told NHTSA about the 2012 GMC Sierra 2500 Hd

Truck is a diesel. Fuel pump blew up and died in the middle of the street. Now I'm being told the Fuel system needs completely re done and will cost me 10g. I also found a lawsuit for this issue as well.

WHILE TRAVELING ON THE INTERSTATE AT SPEED AND PASSING SLOWER TRAFFIC; ENGINE POWER FELL OFF, CHANGE FUEL FILTER NOW, ENGINE DERATE, AND CHECK ENGINE LITE, OCCURED. I HAD TO MANEUVER WITH NO POWER THROUGH THE TRAFFIC TO GET OUT OF THE TRAVEL LANES. I WAS THEN STRANDED ON THE INTERSTATE AS THE TRUCK WOULD NOT START. I WAS ABLE TO GET A MECHANIC TO COME AND CHANGE THE FUEL FILTER ON THE SIDE OF THE HIGHWAY, BUT THE TRUCK WOULD NOT START. THE TRUCK WAS EVENTUALLY TOWED TO A SHOP WHERE IT WAS DIAGNOSED WITH A CATASTROPHIC FAILURE OF THE FUEL PUMP (DIESEL MOTOR DRIVEN PUMP).

EMISSIONS FAILURE. NOX SENSOR, DEF SYSTEM. DRIVING, DISPLAY STATES, POOR DEF QUALITY. TOOK IN FOR REPAIR, STILL DEF QUALITY. TRUCK HAS SLOWED TO 55MPH, WILL SLOW TO 4 MPH IN 39 MILES. THEY ARE TROWING PARTS AT IT AT MY EXPENSE. CAN'T PROPERLY DIAGNOSE. THIS PROBLEM IS FROM 2010- CURRENT MODELS OF THESE DIESELS.

THE FUEL INJECTION PUMP CP4 HAD A CATASTROPHIC FAILURE AS I WAS DRIVING ON A HEAVILY TRAVELED FOUR LANE HIGHWAY, US RT.20. I LOST POWER STEERING AND BRAKES. I FELT FORTUNATE THAT I WAS NOT TOWING A 16,000 LB. FIFTH WHEEL CAMPER DOWN A MOUNTAIN ROAD.I SAY THIS BECAUSE IT WAS EXTREMELY DIFFICULT TO MAINTAIN CONTROL OVER THE TRUCK STEERING IT AND BRINGING IT TO A CONTROLLED STOP. I HAVE READ ABOUT THESE PUMPS FAILING ON NUMEROUS DIESEL FORD AND GM TRUCKS. I ALSO FEEL IF A WOMAN OR SMALL PERSON HAD THIS HAPPEN TO THEM THE OUTCOME COULD END IN LOSS OF CONTROL RESULTING IN INJURIES EVEN DEATHS. THE ONLY ONE THAT KNOWS THE ACTUAL NUMBER OF PUMPS THAT HAVE FAILED IS THE MANUFACTURERS, WHO WILL NOT SHARE THAT INFORMATION WILLINGLY. *JS

ENGINE WILL INCREASE IDLE FROM 700 TO 900 AT ANY TIME. ONE CAN BE SITTING AT A TRAFFIC LIGHT AND IT MIGHT INCREASE OR DECREASE. I PULL A 5TH WHEEL (35 FEET) AND IT IS VERY DIFFICULT TO STOP WITH THE ENGINE TRYING TO KEEP GOING. ALSO IT IS VERY SCARY TO STOP ON SLIPPERY ROADS. THIS DID NOT START UNTIL THE VEHICLE HAD APPROX. 35,000 MILES ON IT. THE DEALER TELLS ME IT IS NORMAL, BUT I HAVE TALKED TO OWNERS OF THE GM DIESEL FROM MODEL YEAR 2008 THROUGH 2015 AND NONE OF THEM HAVE THIS CONDITION. *TR

WHILE THE VEHICLE WAS BEING DRIVEN, IT JUST WENT DEAD, NO ENGINE, NO ELECTRIC, NO NOTHING. THE VEHICLE WAS LEFT IN PLACE AND AT SOME POINT, CAUGHT FIRE AND BURNED. A TOTAL LOSS. TO DATE, THE INSURANCE COMPANY HAS NOT PAID ME FOR MY LOSS BUT RATHER HAS GONE TO GREAT LENGTHS TO INVESTIGATE ME PERSONALLY, LOOKING FOR ANY REASON TO NOT PAY. SO, I'VE BEEN MAKING TWO VEHICLE PAYMENTS FOR THE LAST 8 MONTHS. AS A RESULT, I AM STRUGGLING FINANCIALLY. *TR

APPARENTLY GM USES PEANUT OIL TO LUBRICATE WIRING SO THEY CAN MORE EASILY INSULATE, ETC (ACCORGING TO THE GM DEALER). THIS ATTRACTS RATS AND MICE WHICH CHEW UP THE WIRING - POTENTIALLY IMPACTING SENSORS AND OTHER ITEMS CONTROLLING CRUISE, STABILITY/TRACTION CONTROL, AND ANY NUMBER OF ELECTRICAL SYSTEMS THAT THE DRIVER MAY BE RELYING UPON FOR SAFETY. I ACTUALLY HAD MAP SENSOR WIRES CHEWED UP THAT DISABLED MY STABILITY/TRACTION SYSTEMS AND INHIBITED ENGINE PERFORMANCE. LUCKILY FOR ME IT HAPPENED IN MY DRIVEWAY RATHER THAN ON THE HIGHWAY. DEALER CLAIMS IT IS NOT WARRANTY ITEM EVEN THOUGH CAUSED BY A PROCESS THAT GM ELECTS TO USE IN BUILDING THE VEHICLE. THIS COULD IMPACT ANY/EVERY VEHICLE THAT GM BUILDS WITH USE OF PEANUT OIL (MAY INDEED BE ALL OF THEIR MODELS). *TR

VEHICLE WAS TAKEN TO GMC DEALER FOR HEADLIGHT DEFECT AND WE WERE INFORMED THAT THEY WOULD HAVE TO ORDER PARTS. DROVE TRUCK BACK TO SITE AND WHILE TRUCK WAS RUNNING BUT STATIONARY SMOKE WAS OBSERVED COMING FROM THE ENGINE COMPARTMENT. WHEN THE HOOD WAS RAISED THE ENTIRE TRUCK BECAME ENGULFED AND COMPLETELY BURNED. *TR
