THE VEHICLE WAS MOVING AT A HIGHWAY SPEED OF APPROXIMATELY 65 MPH, WHEN IT GOT INTO A COLLISION WITH ANOTHER VEHICLE. THE OTHER VEHICLE MADE AN ABRUPT STOP ON THE HIGHWAY IN FRONT OF THE 2004 CHEVROLET AVEO, WHICH CAUSED THE AVEO TO HIT THE BACK OF THE SUDDENLY STOPPED VEHICLE. UPON IMPACT, THE AIRBAG DID NOT DEPLOY, WHICH FROM MY UNDERSTANDING SHOULD HAPPEN WHEN TRAVELING AT THAT SPEED. IN FACT IT ESPECIALLY SHOULD HAVE DEPLOYED, DUE TO THE FACT THAT THE IMPACT DAMAGED THE FRONT OF THE VEHICLE. MY CONCERN IS THAT I HAVE BOUGHT TWO OTHER VEHICLES FROM THE SAME MANUFACTURER SINCE MY PURCHASE OF THIS VEHICLE. I WANT TO MAKE SURE THAT MY FAMILY IS SAFE WHEN RIDING IN THESE VEHICLES.

BASICALLY I AM WRITING BECAUSE GM ISSUED A RECALL IN JUNE 2014 LETTING ME KNOW THAT MY CAR HAS AN ISSUE WHICH MAY LEAD TO A FIRE IN MY CAR. THE PROBLEM IS THAT A YEAR HAS PASSED AND THE STATUS OF THAT RECALL STILL IS "GENERAL MOTORS WILL PROVIDE ITS PLAN FOR REMEDYING THE DEFECT AS SOON AS IT IS CONFIRMED." I HONESTLY FEEL THEY HAVE FORGOTTEN ALL ABOUT IT. I DON'T THINK THIS SHOULD BE AN ISSUE THAT SHOULD TAKE SUCH A LONG TIME TO GET FIXED.
