NHTSA Complaint #10060583 — 2002 PONTIAC GRAND AM

I HAVE HAD MY CAR IN NUMEROUS TIMES TO DEALERSHIP AND STILL HAVE NOT BEEN ABLE TO FIX PROBLEM. WHEN I TRAVEL DOWN INTERSTATE THE RPM LOCKS IN AT AROUND 2.6--EVERY SO OFTEN IT WILL KICK OUT AND MOVE PAST 3. THIS CAUSES A JERKING MOTION IN CAR THAT IS QUITE NOTICEABLE BY EVERYONE IN CAR. I HAVE ASSISTED MY DEALERSHIP IN FINDING THE CAUSE OF THIS PROBLEM, BY HAVING A MECHANIC TAKE IF FOR TEST DRIVES, APPLYING SCANNING TOOL, AND A DATA RECORDER TO ENGINE. I HAVE PUT ON OVER 600 MILES TRYING TO DIAGNOSIS PROBLEM. I HAVE NOW BEEN TOLD THAT THEY REALLY DON'T KNOW WHAT IS CAUSING THE SYMPTOMS, BUT THINK IT MAY A PROGRAMMING ERROR. THEY STATE THAT THE COMPUTER CONTROLLING THE TORQUE CONVERTER IS NOT WORKING PROPERLY. THEY STATE GMC HAS APPROX 13 OTHER CARS IN US THAT IS DOING THIS, BUT THEY DO NOT KNOW WHAT IS CAUSING THE PROBLEM OR HOW TO FIX IT. THEY ARE CURRENTLY WORKING ON A FIX---BUT THIS MAY TAKE YEARS SINCE ANY CHANGES MADE, HAVE TO GO THROUGH GOV. IN THE MEAN TIME I AM SUPPOSE TO CONT TO DRIVE THIS CAR AND LIVE WITH THE SUDDEN QUICK JERKS THAT I GET EVERY 1-2 MILES GOING DOWN ROAD, WAIT FOR THE COMP UPGRADE, AND HOPE THAT THIS IS THE CAUSE!! IF NOT WE START OVER. I AM REAL FRUSTRATED WITH THIS WHOLE PROCESS AND THE WAY THIS HAS BEEN HANDLED AT MY DEALERSHIP. I WANT A RESOLUTION TO THIS ASAP. THE CAR ONLY HAS 27,000 MILES ON, AND SHOULD NOT BE HAVING THIS MUCH PROBLEMS. AT THIS POINT I AM VERY DISAPPOINTED IN MY SERVICE I HAVE RECEIVED AND IN THE WHOLE GMC TECHNICIAN STAFF, AND PRODUCT. *JB
