NHTSA Complaint #10202791 — 2007 GMC ACADIA

I LEASED A 2007 ACADIA ON 5-24-07 AND SHORTLY AFTER TAKING DELIVERY I FELT THERE WAS SOMETHING WRONG WITH THE TRANSMISSION AND THE WAY IT SHIFTED, I NOTIFIED THE DEALERSHIP ABOUT THE PROBLEM AND TOOK IT IN FOR REPAIR. THEY TOLD ME THEY COULDN'T GET THE PROBLEM TO REPEAT AND FELT THERE WAS NOTHING WRONG. ON 6-14-07 I TOOK A TRIP TO FLORIDA FROM MICHIGAN AND GOT 11 MILES INTO GEORGIA AND THE TRANSMISSION DECIDED TO SHIFT INTO 1ST GEAR GOING 70 MPH. I MANAGED TO GET OFF THE ROAD AND WAS WONDERING WHAT WENT WRONG. I PUSHED THE ONSTAR BUTTON AND THEY GOT ME TO A DEALERSHIP (NEWTON GMC IN TENNESSEE), THEY DONE A QUICK COMPUTER CHECK FOR ERROR CODES AND FOUND MANY CODES THAT THEY DIDN'T KNOW WHAT THEY WERE BUT THEY SAID IT WAS RELATED TO THE TRANSMISSION. I LEFT THE ACADIA WITH THEM AND FINISHED MY TRIP TO FLORIDA IN A FORD PICKUP. AFTER 2 WEEKS THE DEALERSHIP GOT THE OK FROM GM TO REPLACE THE TRANSMISSION. I AM STILL HAVING PROBLEMS WITH THE NEW TRANSMISSION SHIFTING CORRECTLY. AS OF 9-17-07 THERE IS A NEW SOFTWARE UPDATE THE DEALERSHIPS WILL HAVE TO CORRECT THE SHIFTING PROBLEMS FOR 2007 MODELS, THE 2008 MODELS ALREADY HAVE THE NEW SOFTWARE IN THEM WHEN THEY LEAVE THE ASSEMBLY PLANT. THIS PROBLEM MAY BE ON THE 2007 SATURN OUTLOOK BECAUSE THEY HAVE THE SAME TRANSMISSION. *TR
