2010 Chevrolet Suburban 2500

THERE ARE SEVERAL CRACKS IN THE DASH OF MY 2010 CHEVROLET SUBURBAN AS EXPLAINED BELOW. ONE OF THESE CRACK IS IN THE AREA OF THE PASSENGER SIDE AIRBAG WHICH IS MOUNTED ON TOP OF THE DASH. AS THE DASH EXPANDS IN THE HEAT, TYPICALLY IN THE HOT MONTHS OF THE SUMMER, THE PLASTIC PORTION OF THE DASH WILL COVER THE AIRBAG PORTION OF THE DASH. I AM CONCERNED THAT IF I DO NOT NOTICE THIS AND THE VEHICLE IS INVOLVED IN A CRASH, THE AIRBAG WILL NOT OPERATE PROPERLY. I AM AFRAID VEHICLE OCCUPANTS MIGHT BE INJURED BY THE DASH IF THE AIRBAG DEPLOYED UNDER THE PLASTIC PORTION OF THE DASH OR THAT THEY WILL BE INJURED IF THE AIRBAG WOULD NOT DEPLOY PROPERLY. THERE ARE ALSO TWO CRACKS IN THE DASH IN THE AREA OVER THE INSTRUMENT CLUSTER WHICH ALLOWS A PORTION OF THE DASH TO BE COMPLETELY REMOVED FROM THE MAIN DASHBOARD. THIS PORTION OF THE DASH THAT CAN BE REMOVED CAUSES A PROBLEM ON LONG TRIPS DUE TO THE FACT THAT IT WILL VIBRATE OUT OF PLACE. MY CONCERN WITH THIS PIECE IS ITS LOCATION IN RELATION TO THE STEERING WHEEL. I AM CONCERNED THAT IF THIS PIECE MOVES OUT OF PLACE, IT COULD MOVE INTO THE OPEN AREA AT THE TOP OF THE STEERING WHEEL AND INTERFERE WITH MY ABILITY TO CONTROL THE STEERING OF THE VEHICLE. I WAS ALSO INFORMED BY A LOCAL DEALERSHIP THAT MY AIRBAG OR AIRBAGS HAVE BEEN RECALLED. IN REGARDS TO BOTH OF THESE ISSUES, THE CUSTOMER ASSISTANCE REPRESENTATIVE ADVISED THAT GM IS AWARE OF BOTH PROBLEMS, BUT THAT THEY ARE STILL INVESTIGATING THE PROBLEMS AND POSSIBLE RESOLUTIONS. HOW LONG DOES IT TAKE TO INVESTIGATE THE CAUSE OF THE DASH PROBLEMS? THIS HAS BEEN A WELL DOCUMENTED PROBLEM FOR SEVERAL YEARS THAT AFFECTS MANY VEHICLES, YET GM CLAIMS NOT TO KNOW WHAT CAUSED IT OR TO TAKE ANY RESPONSIBILITY FOR THE INFERIOR DASHES THAT WERE PLACED IN QUITE FEW YEAR MODELS OF THEIR VEHICLES. I FEEL THAT THIS BROKEN DASH IS A SAFETY ISSUE WITH THE VEHICLE.
