SINCE MAY 2012 OUR "CHECK AIR BAG" LIGHT HAS REPEATEDLY APPEARED. THE DEALER TOLD US THAT WHEN THAT LIGHT IS ON, THE AIRBAGS WILL NOT DEPLOY. THE VEHICLE HAS BEEN TAKEN TO THE DEALER TO BE REPAIRED AT LEAST 4 TIMES. THE MOST RECENT OF WHICH WAS ON DECEMBER 20, 2012. WE WERE TOLD GM DISCOVERED A NEW REPAIR THAT THEY WERE 90% CERTAIN WOULD FIX THE PROBLEM WITH THE PASSENGER AIRBAG DETECTOR. THE LIGHT APPEARED AGAIN TONIGHT, LESS THAN ONE MONTH AFTER THE NEW REPAIR. GMC HAS BEEN COMPLETELY NON-RESPONSIVE. THE DEALER (KOONS) WOULD ONLY REPAIR THE CAR WHEN THE LIGHT APPEARS, WHICH IS A PROBLEM WHEN IT FLASHES INTERMITTENTLY. THE FACT THAT WE CANNOT RELY ON OUR AIRBAGS TO DEPLOY IS AN EXTREME SAFETY CONCERN. *TR
