2013 GMC SIERRA Power Train Problems

INITIALLY I FELT THE PROBLEM AS A SLIGHT "MISSING" IN THE ENGINE UNDER VERY LIGHT ACCELERATION BETWEEN 40 MPH AND 55MPH AND MORE PRONOUNCED UNDER CONSTANT THROTTLE GOING UP GRADES ON THE HIGHWAY AT A SPEED OF ~55 MPH (1400-1500 RPM). THE VEHICLE SEEMED TO BE "LUGGING", AND THEN THE RPM WOULD INCREASE BY ~20% IMMEDIATELY FOR A SHORT DISTANCE AND THEN DROP BACK (ALL AT CONSTANT THROTTLE) TO 1400-1500 RPM. WHEN DRIVING ON THE HIGHWAY IN CRUISE CONTROL AT 60 MPH AND GOING UP A GRADE, THE VEHICLE WOULD SHOW SIGNS OF "STRAINING" AND IMMEDIATELY INCREASE IN THE RPM BY ABOUT 20% WITH AN ATTENDANT ACCELERATION. THEN THE RPM WOULD INCREASE INSTANTLY BY ABOUT 1000 RPM AND THE VEHICLE ACCELERATES RAPIDLY UNTIL I ENGAGE THE BRAKES. MY DEALER OBSERVED THE SAME CHARACTERISTICS AND DETERMINED THAT IT WAS A TORQUE CONVERTER PROBLEM AND ON 07/25/2014 THEY INSTALLED A NEW TORQUE...

HELLO, THE DATE AND MILEAGE ABOVE IS NOT ACTUAL DATE OF FIRST INCIDENT, BUT IS THE FIRST TIME I TOOK IT IN FOR THE FIRST OIL CHANGE AND VEHICLE INSPECTION WHICH ALSO WAS THE FIRST TIME I COMPLAINED TO THE DEALERSHIP ABOUT THE ISSUE. MY TRANSMISSION SLIPS BETWEEN 2ND AND 3RD GEAR AT LEAST 4 TIMES A MONTH. THE DEALER TOLD ME THAT IF I CANT PROVE IT OR IF IT DOESN'T DO IT WHEN THEY DRIVE IT THEN THEY CANT PERFORM A DIAGNOSTIC TEST TO FIX THE PROBLEM. THE SELLER WHO SOLD ME THE VEHICLE CALLED ME TWICE TO SEE HOW IM ENJOYING MY TRUCK AND I COMPLAINED TO HIM BOTH TIMES ABOUT THE ISSUE AND HE TOLD ME THE SAME THING ABOUT MY ISSUE. I EVEN LEFT VOICEMAILS TO HIM ABOUT IT AND HE NEVER RETURNED MY CALLS UNTIL I MADE A YEAR (3/16/14) OWNING MY TRUCK AND...

AT THIS OCCURRENCE THE HOOD LATCH DOES NOT KEEP THE HOOD TIGHT WHEN CLOSED. THE HOOD RATTLES AT SPEEDS OVER 35MPH AND APPEARS AS THOUGH IT IS GOING TO OPEN. AS A RESULT OF ATTEMPTING TO SUFFICIENTLY SECURING THE HOOD, I SUBSEQUENTLY DENTED THE HOOD. I HAVE HAD THE BODY DEPARTMENT AT THE LOCAL DEALERSHIP LOOK AT IT AND THEY FOUND THAT THE HOOD LATCH NEEDED TO BE ADJUSTED. AFTER ANOTHER 2500 MILES, THIS RATTLE HAS RETURNED. THE COMPLAINT IS THAT THIS IS THE SECOND 2013 SIERRA DENALI THAT I HAVE OWNED SINCE OCTOBER 2012, SINCE THE DEALERSHIP BOUGHT BACK THE FIRST ONE AFTER NUMEROUS PROBLEMS INCLUDING THE TRANSMISSION BEING REPLACED AT 6250 MILES AND NUMEROUS EFFORTS TO FIX THE HOOD. SAME PROBLEM TWO TRUCKS IS A CAUSE FOR CONCERN! *TR

TL* THE CONTACT OWNS A 2013 GMC SIERRA 1500. WHILE DRIVING 40 MPH, THE CONTACT STATED THAT THE VEHICLE WOULD JERK AND SHIFT IN BETWEEN GEARS. THE VEHICLE WAS TAKEN TO THE DEALER BUT WAS NOT REPAIRED NOR WAS THE FAILURE DIAGNOSED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 200.

THE TRANSMISSION ON THIS VEHICLE SLIPS SOMETIMES BETWEEN 2ND AND 3RD GEAR AND ALSO WHEN PARKED ON A HILL AND PUT INTO DRIVE THE TRANSMISSION SHIFTS LATE INTO 1ST GEAR. *TR
