NHTSA Complaint #10243962 — 2007 GMC ACADIA

DRIVING MY 2007 GMC ACADIA. CAME UPON A BUSY STATE HIGHWAY. AFTER COMING TO A STOP, I SAW AN OPENING AND PRESSED ON THE ACCELERATOR TO CROSS THE 4 LANE ROAD. WHEN I PRESSED THE ACCELERATOR, THE CAR JUST STARTED TO CREEP OUT INTO TRAFFIC. THE ENGINE RPM'S INCREASED, BUT THE CAR WAS MOVING AT WALKING SPEED. IT WAS OBVIOUS THAT THE TRANSMISSION HAD NOT SHIFTED BACK INTO 1ST GEAR. I TRIED TO MANUALLY SHIFT INTO LOW, BUT IT DID NOT RESPOND. I FINALLY WAS ABLE TO GET IT GOING FAST ENOUGH TO HAVE IT PICK UP SOME SPEED TO GET ACROSS THE LANES OF TRAFFIC. ON THE WAY HOME, EVERY TIME I CAME TO A STOP, THE CAR ACTED THE SAME WAY UPON ACCELERATION. THE ONLY WAY I WAS ABLE TO GET THE CAR TO GO BACK INTO 1ST GEAR WAS TO SHUT THE CAR OFF AND RESTART IT. EVEN DOING THAT, IT ONLY LASTED UNTIL THE NEXT TIME I STOPPED. AFTER LETTING THE CAR SIT OVER NIGHT, IT PERFORMED FINE THE NEXT DAY. THIS IS THE SECOND TIME I HAVE HAD PROBLEMS WITH THIS ISSUE. THE FIRST TIME THE GMC DEALER 'FLASHED' (REPROGRAMMED) THE TRANSMISSION, EVEN THOUGH IT WAS NOT ACTING UP WHEN THE CAR WAS TAKEN INTO THE SHOP. I SPOKE WITH A CAR DEALER AT THE SHOP, AND HE OWNED THE SAME VEHICLE. HIS TRANSMISSION HAS BEEN 'REFLASHED' 6 OR 7 TIMES FOR THE SAME ISSUE. IF THIS ISSUE IS NOT ADDRESSED "PROPERLY", I BELIEVE SOMEONE SOMEWHERE WILL BE INJURED OR KILLED. THE CONDITION MY VEHICLE EXHIBITED LEAVES ME WITH A VERY UNEASY FEELING (I.E. WHEN I PRESS THE ACCELERATOR, I EXPECT THE CAR TO MOVE). IF REFLASHING THE TRANSMISSION (1, 2, 3, 4...7 TIMES) DOES NOT FIX THE PROBLEM, THEN MAYBE SOMETHING DIFFERENT NEEDS TO BE DONE. *TR
