2011 GMC Sierra Engine Problems

WHILE DRIVING DOWN THE INTERSTATE AT 70 MPH MY SERVICE TRACTION CONTROL MESSAGE, SERVICE STABILITRAK MESSAGE, CHECK ENGINE LIGHT, AND REDUCED ENGINE POWER MESSAGE CAME ON. THE VEHICLE STARTED RUNNING VERY ROUGH IT WOULD NOT GO ABOVE 50 MPH. I DROVE APPROXIMATELY 3 MILES TO GET OFF THE INTERSTATE INTO THE GAS STATION PARKING LOT. I TURNED IT OFF FOR ABOUT 10 MINUTES WHEN I TURNED IT BACK ON ONLY THE CHECK ENGINE LIGHT WAS ON I TOOK IT TO THE SHOP AND THEY RAN TESTS AND SAID IT WAS THE BATTERY. TWO WEEKS LATER IT HAPPENED AGAIN SAME THING WHEN I TURNED IT OFF IT WORKED FINE AFTER SITTING FOR 10 MINUTES I GOT HOME AND WHEN I GOT A CHANCE TO LOOK AT IT TO DAYS LATER THE CHECK ENGINE LIGHT WAS OFF. I HAVE READ A LOT AND FORUMS ABOUT PEOPLE HAVING THE SAME ISSUE BUT NO RESOLUTION TRULY BEING FOUND. THIS IS A 2011 GMC SIERRA 1500 WITH THE ALL-TERRAIN PACKAGE AND ONLY HAS ABOUT 60,000 MILES ON IT IT GETS OIL CHANGES REGULARLY. THIS REALLY MAKES ME THINK THIS IS SOMETHING GM SHOULD LOOK INTO.

AFTER APPLYING BRAKE TO SLOW DOWN TO < 5 MPH (NOT COMING TO A HALT) AND THEN TRYING TO ACCELERATE, VEHICLE BECOMES UNRESPONSIVE FOR 1 TO 2 SECONDS; IT FEELS LIKE THE TRANSMISSION GOES INTO NEUTRAL DURING THE BRAKING PERIOD AND WHEN GAS PEDAL IS APPLIED, THERE IS A 1 - 2 SECOND TIME PERIOD WHERE VEHICLE IS TRYING TO FIGURE OUT SOMETHING AND PREVENTS ANY ACCELERATION. WHY IS THIS DANGEROUS? I FOUND MYSELF IN A LEFT TURN ONLY LANE/GREEN LIGHT WITH OPPOSING TRAFFIC, AND I ATTEMPTED THE LEFT TURN WITH ONCOMING TRAFFIC BECAUSE I THOUGHT THAT I HAD AMPLE TIME BUT THE VEHICLE JUST SAT THERE FOR 1 - 2 SECONDS, AND WITH THAT I FOUND MYSELF IN A DANGEROUS PREDICAMENT BECAUSE THE ONCOMING TRAFFIC WAS GETTING VERY CLOSE. IF THE VEHICLE HAD RESPONDED WHEN I NEEDED IT TO, IT WOULD NOT HAVE BEEN A CLOSE CALL. THIS BEHAVIOR WITH THE VEHICLE CAN BE REPRODUCED AT WILL, EVERY TIME. THERE ARE MANY FORUMS ON THE INTERNET WHERE MANY PEOPLE ARE COMPLAINING ABOUT THIS SAME ISSUE WITH THE DRIVE-TRAIN, GMC KNOWS ABOUT IT, BUT REFUSES TO DO ANYTHING ABOUT IT. *TR

WHILE DRIVING ON INTERSTATE THE ENGINE SHUT DOWN TO 1/2 POWER AND BEGAN TO SHAKE/VIBRATE. THE TOP SPEED THEN WAS ABOUT 40MPH. I FINALLY PULLED OVER AND READ MANUAL ON HOW TO RESET IT. IT WORKED PROPERLY THEN. THIS HAS HAPPENED 4 OTHER TIMES. THE LATEST INCIDENT HAPPENED YESTERDAY, WITH OUT USING CRUISE CONTROL. TRAVELING AT 30 MPH IT SHUT ME DOWN AGAIN . ONE OF THE SCARIEST TIMES , I WAS TRAVELING IN 5 LANES OF TRAFFIC AND IT SHUT ME DOWN TO HALF POWER AND IT WAS QUITE DANGEROUS FOR US TO TRY AND MERGE OUT OF THE WAY AND GET OFF TO A SAFE SPOT ON SIDE OF INTERSTATE. I CALLED THE DEALER AND THEY TOLD ME THERE HAS NOT BEEN A RECALL ON THIS ISSUE, BUT IT SEEMS VERY MUCH LIKE A SAFETY ISSUE WITH ME. THE DEALER ALSO TOLD ME AS WELL AS OTHER AUTO SPECIALIST IS THAT THIS IS A COMMON PROBLEM WITH THIS MODEL OF VEHICLE AND THAT IT WILL COST ABOUT 700 DOLLARS TO REPLACE THE THROTTLE CABLE ASSEMBLY. *TR

I OWN A 2011 GMC SIERRA 3500 6.6 DURAMAX DIESEL TRUCK. WHEN THE TRUCK IS "REGEN-ING" THE "DPF", RAW FUEL LEAKS FROM AN EXHAUST COUPLING LOCATED AT THE TURBO AND DOWN-PIPE SATURATING THE HOT EXHAUST PIPE WITH FUEL. WHEN YOU COME TO A STOP WHILE IT IS IN THIS REGEN MODE WHITE SMOKE BOILS OUT FROM UNDER THE HOOD AND ENTERS THE CABIN INDUCING A COUGHING FIT AND BURNING EYES. I TOOK THE TRUCK TO A GMC DEALER IN SAN ANGELO TX AND TOLD THEM ABOUT THE PROBLEM. WAS TOLD THAT THEY COULDN'T REPLICATE THE PROBLEM THAT I WAS DESCRIBING AND THAT I SHOULD REST ASSURED BECAUSE "DIESEL WON'T BURN ANYWAY". *TR
