NHTSA Complaint #11296896 — 2012 GMC SIERRA DENALI

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.
