I WAS ON THE INTERSTATE IN CINCINNATI, OHIO WHEN A DEER CROSSED OVER THE JERSEY WALL ONTO THE ROADWAY AS I WAS JUST BEGINNING TO EXIT. I HIT THE DEER AT A MINIMUM SPEED OF 45-50MPH. MY AIRBAG DID NOT DEPLOY. ALTHOUGH I WAS UNHARMED I AM CONCERNED ABOUT THE FAILURE OF THE AIRBAG TO DEPLOY GIVEN MY SPEED AND FRONT IMPACT. MY VEHICLE HAS ALSO RECENTLY HAD AN INTERMITTENT ISSUE WITH SUDDEN LOSS OF POWER THAT HAS BEEN ATTRIBUTED TO THE STABILITY CONTROL SYSTEM. GIVEN THE RECENT RASH OF INCIDENTS SURROUNDING GMC VEHICLES AND THE LACK OF RECALLS ON THE TERRAIN VEHICLE, I AM REPORTING THESE INCIDENTS AT THIS TIME AS I AM CONCERNED THAT THEY MAY BE INDICATIVE OF BROADER PROBLEM WITH THE TERRAIN MODEL OF VEHICLE. *TR
