I HAVE A ISSUE WITH MY DASHBOARD CRACKING ALONG THE AIRBAG MODULE DOOR. I BELIEVE IF I WAS OR INVOLVED IN A ACCIDENT AND THE AIR BAGS ARE DEPLOYED THE PIECES OF DASH CAN BECOME FRAGMENTS AND CAUSE EXCESSIVE INJURY AND ALSO COULD DEFLATE THE AIRBAGS UPON EXPANSION. CAUSING MORE INJURY THAN DEEM NECESSARY.

THE DASHBOARD IN MY 2011 GMC SIERRA DENALI 1500 HAS MULTIPLE CRACKS IN THE DASHBOARD, THEY HAVE APPEARED SIGNIFICANTLY WITHIN IN THE LAST YEAR AND GOTTEN MUCH LARGER TO THE POINT WHERE A "HOLE" HAS OPENED UP DUE TO A PIECE OF THE DASHBOARD BREAKING LOOSE AND FALLING INSIDE OF THE DASH CONSOLE. THE CRACKS AND LOOSE DEBRIS HAVE CAUSED ME CONCERN BECAUSE IF THE AIRBAGS WERE TO DEPLOY DURING A MOTOR VEHICLE ACCIDENT THE OCCUPANTS OF THE VEHICLE WOULD BE SUBJECTED TO FLYING DEBRIS/ SHRAPNEL FROM THE DASHBOARD. I CONTACTED MY LOCAL DEALERSHIP AND THEY STATED THAT IT IS AN AESTHETIC ISSUE WHICH WOULD NOT BE COVERED UNDER ANY KIND OF WARRANTY. THIS IS A KNOWN ISSUE WITH ITS OWN FACEBOOK PAGE AND PLENTY OF DOCUMENTED CASES ONLINE. GM HAS ACKNOWLEDGED THERE WAS A PROBLEM AND HAS OFFERED TO REPLACE SOME DASH BOARDS ON A CASE BY CASE BASIS AT A REDUCED COST. HOWEVER, THIS STILL SEEMS TO BE UNACCEPTABLE DUE TO THE FACT THAT PERSONAL INJURY INCLUDING AND UP TO LOSS OF LIFE COULD BE A RESULT OF THIS DEFECT.

FIRST CRACK IS OVER THE GAUGES ON THE DASH, AND THE SECOND IS RIGHT OVER TOP OF THE AIR BAG. THIS IS A SERIOUS ISSUE WITH NO RECALLS OR ASSISTANCE FROM VEHICLE MANUFACTURERS. THE CRACKS ARE EITHER STARTED VIA DRIVING AND CRACKING DUE TO VIBRATION OF THE ROAD, OR THEY CRACK FROM PREMATURE WEAR VIA THE SUN FADING THE MATERIALS. IT IS A VERY SERIOUS SAFETY CONCERN, SEEING HOW IF THE AIR BAG WERE TO DEPLOY IT WILL SEND MANY SHARP PIECES OF DASHBOARD PLASTIC INTO THE PASSENGER OR MYSELF THE DRIVER. THIS ISSUE NEEDS TO BE ADDRESSED, IT IS A VERY EXPENSIVE FIX, AND A SAFETY ISSUE THAT NEEDS AN IMMEDIATE RECALL OR ADDRESS.
