2011 GMC Sierra Powertrain & Transmission Problems

IN VERY COLD WEATHER, THE SHIFTER STICKS AND WILL NOT MOVE TO SHIFT IN ANY GEAR. *JS

GM PERFORMED A RECALL FOR FRACTURED TRANSMISSION DIPSTICK TUBE ON MY TRUCK. THEY TOOK A TUBE OF FOAM AND PLASTIC STRAPPED IT TO THE TUBE. I NEVER SAW THE REASONING! THE TUBE HAS FRACTURED AND NOW HAS TO BE REPLACED. WHY DID THE NOT FIX THIS PROPER IN THE FIRST PLACE. NOW I NEED TO MAKE TWO MORE APPOINTMENTS TO GET THIS FIXED. MY TRANSMISSION IS OPEN TO THE ELEMENTS, WATER AND DIRT! *TR

TL* THE CONTACT OWNS A 2011 GMC SIERRA. THE CONTACT STATED THAT THE VEHICLE WAS PARKED IN A RESIDENTIAL DRIVEWAY WHEN IT ROLLED AWAY IN REVERSE AND INTO THE STREET. A CRASH DID NOT OCCUR. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION BUT THEY WERE UNABLE TO DIAGNOSE THE CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND DID NOT PROVIDE ANY ASSISTANCE. THE FAILURE MILEAGE WAS 28,000. UPDATED 02-08/13 *BF UPDATED 02/11/13

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
