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

I PURCHASED A 2012 GMC SIERRA DENALI FROM STAHL MOTORS IN MONTEREY, CA IN FEBRUARY OF 2015. THEY ARE NOT WILLING TO PAY FOR THE DAMAGES TO MY TRUCK EVEN THOUGH THEY SOLD ME A COMPLETELY DANGEROUS VEHICLE, WHICH I WILL EXPLAIN. MY TRUCK DIDN'T FEEL RIGHT AS I WAS DRIVING SO I DECIDED TO TAKE IT TO A SHOP TO GET LOOKED AT. THERE IS A LONG LIST OF THINGS THAT IS WRONG WITH THE VEHICLE, BUT I WILL MENTION JUST THE MAIN ONES. THE TRUCK WAS SOLD TO ME WITHOUT THE REAR BRAKES HOOKED UP. THE BRAKE LINES FOR THE REAR CALIPERS WERE CAPPED OFF BY THE REAR DIFFERENTIAL. WHEN THE MECHANIC SHOP DISCOVERED THAT, THEY ALSO DISCOVERED THE MASTER CYLINDER WAS COMPLETELY DRY, WHICH CAUSED DAMAGE TO MY FRONT BRAKES. THERE WAS NO CROSS MEMBER UNDERNEATH THE VEHICLE FROM FRAME TO FRAME. IT WAS TORCHED OUT, THEREFOR LEAVING ZERO SUPPORT FOR THE FRAME OF THE TRUCK AS WELL AS THE FRONT DIFFERENTIAL. WHICH NEEDED TO BE REBUILT CAUSED FROM EXCESSIVE MOVEMENT LEFT TO RIGHT. FRONT DIFFERENTIAL NEEDED TO BE REBUILT CAUSED FROM THE DAMAGE OF NO CROSS MEMBER IN PLACE. BALL JOINTS WERE ALSO AFFECTED (ABOUT TO POP OUT OF CONTROL ARMS) DUE TO WRONG PARTS INSTALLED IN FRONT SUSPENSION OF VEHICLE.

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

PULLING INTO A PARKING SPOT IN A PARKING GARAGE GOING NO MORE THAN 3 MILES PER HOUR, OR HOWEVER FAST THIS VEHICLE CAN GO WHILE FOOT IS RESTING ON BRAKE, GETTING READY TO FULLY BRAKE. AS I PRESSED DOWN ON BRAKE TO STOP, THE VEHICLE CONTINUED AS IF THE ANTI-LOCK BRAKE SYSTEM SLIPPED, CAUSING THE TRUCK TO DRIVE FORWARD CRASHING THROUGH THE SHEETROCK WALL AND FINALLY STOPPING AFTER HITTING THE GLASS WINDOWS. TWO WEEKS LATER, AFTER ALL COSMETIC REPAIRS WERE DONE, THE VEHICLE DID THE SAME THING IN ANOTHER PARKING LOT, BUT LUCKILY BROKE BEFORE HITTING THE CURB AND LIGHT POST. I DID FEEL UNDER MY FOOT ON THE BRAKE PEDDLE, AS I PRESSED DOWN TO STOP, A SLIP OF SOME SORT WHICH AT THE SAME TIME CAUSED THE VEHICLE TO PUSH FORWARD RIGHT BEFORE STOPPING. THIS IS DEFINITELY A MALFUNCTION OF SOME SORT WITH THE ANTI-LOCK BRAKE SYSTEM. *TR
