HAD JUST ACCELERATED AFTER STOPPING AT RED LIGHT, REACHING APPROX 25MPH WHEN WE HEARD A VERY LOUD GRATING METAL GRINDING SOUND. ALARMED WE IMMEDIATELY STARTED TO PULL OVER WHEN THE SIDE AIRBAGS DEPLOYED. WE WERE ABLE TO GET OUT OF THE FLOW OF TRAFFIC AND ONTO THE SIDE OF THE ROAD. WE WERE DAZED TRYING TO MAKE SENSE OF WHAT HAD HAPPENED. MY HUSBAND WAS THE DRIVER AND HAD RECEIVED A LARGE CUT ON HIS LEFT FOREARM . WE HAD OWNED THIS CTS FOR 10 WEEKS AND HAD NOT AS YET SIGNED UP FOR ONSTAR . WHILE TRYING TO STOP HIS BLEEDING I REALIZED THAT THE BLOW FROM THE AIRBAGS HAD KNOCKED MY GLASSES OFF AND I COULDN'T FIND MY CELL PHONE, I PUSHED THE ONSTAR BUTTON AND GAVE THEM OUR INFORMATION AND THEY COULD NOT HAVE BEEN MORE HELPFUL. AFTER ESTABLISHING THAT WE WERE ON THE SIDE OF THE ROAD AND OUT OF IMMEDIATE DANGER THEY ARRANGED FOR A TOW TRUCK TO TAKE US TO MEDVED CADILLAC. AS THIS WAS A SAT. WE WERE NOT ABLE TO SPEAK WITH THE REPAIR DEPT. UNTIL MON.WE WERE TOLD THAT GM HAD TO GIVE APPROVAL TO REPAIR THE VEHICLE. EIGHTEEN DAYS LATER 6/26 WE PICKED UP THE CAR AND WERE TOLD THAT THE ENTIRE CAR AND ALL SYSTEMS HAD BEEN CHECKED AND THAT IT WAS SAFE. FOUR DAYS LATER 6/30 I WAS DRIVING HOME AND HEARD A CLACKING NOISE. I STOPPED AND LOOKED AT MY TIRES THINKING I HAD A FLAT. PROCEEDED THE FEW BLOCKS TO GET HOME REALLY AFRAID TO GET BACK IN THIS CAR. WE WERE GOING TO TAKE IT BACK TO MEDVED BUT DROVE A FEW BLOCKS FROM HOME AND STOPPED AT A LIGHT. TURNED THE CORNER HEARD A LOUD METAL CLUNK,
