NHTSA Complaint #10384094 — 2005 CADILLAC CTS

I HAVE A 2005 CADILLAC CTS WITH 67,000 MILES. SINCE ABOUT 65,000 MILES CAR HAS BEEN MAKING A RATTLING SOUND UNDER THE HOOD DURING ACCELERATION. I HAVE GIVEN THE CAR A TUNE UP, OIL CHANGE AND THE CAR HAS OTHER FLUIDS ARE AT LEVEL. ONCE MY CAR HAS ACCELERATED AND THE GEARS HAVE CHANGED (I.E, SECOND GEAR) THE RATTLING SOUNDS STOPS..THE NOISE IS CONTINUOUS AND ONLY HAPPENS AT ACCELERATION, NOT WHILE IDLING. IN ADDITION EVERY NOW AND AGAIN WHEN A FRONT SEAT PASSENGER GETS IN THE CAR THE AIRBAG SENSOR/LIGHT COMES ON THE DASHBOARD. THIS PROBLEM DOESN'T HAPPEN OFTEN BUT IT HAPPENS EVERY ONCE IN A WHILE. UPON DOING MY RESEARCH FOR BOTH THESE ISSUES I FIND THAT I AM NOT THE ONLY ONE HAVING THIS PROBLEM...HOPEFULLY SOMETHING WILL BE DONE SO THAT GM CAN ADDRESS THESE SERIOUS ISSUES WITHOUT HAVING THE CONSUMER/OWNERS HAVING TO PAY AN ARM AND A LEG. *TR
