NHTSA Complaint #11074558 — 1999 BUICK LESABRE

I WAS SITTING AT A RED LIGHT WHEN MY AIR BAG FROM THE STEERING COLUMN DEPLOYED IN MY FACE. I DID NOT HIT ANYTHING. IT WAS ON OR ABOUT 1/25/18. ABOUT A WEEK PRIOR TO THIS EVENT MY HORN BEGAN TO STEADILY BLOW INEXPLICABLY. I DID NOT HAVE ANY REASON TO SUSPECT ANYTHING OTHER THAN A MALFUNCTIONING HORN SO I DISCONNECTED THE WIRES TO THE HORN. WHEN THE AIR BAG DEPLOYED ABOUT A WEEK LATER I CONCLUDED THE AIR BAG WAS INFLATING INSIDE THE STEERING WHEEL APPLYING PRESSURE TO THE HORN SENSOR. I TOOK IT TO THE DEALER WHO, AFTER WEEKS OF INVESTIGATION, CONCLUDED THEY COULD NOT DO ANYTHING TO REPAIR IT AND SUGGESTED I CALL GENERAL MOTORS CUSTOMER ASSIST CENTER. AFTER REVIEWING PICTURES, (NO ONE ACTUALLY PHYSICALLY LOOKED AT IT) GM DECIDED CORROSION TO THE SENSING MODULE CAUSED THE PROBLEM. I CONTEND THEY HAVE A DEFECTIVE VALVE WHICH OVERTIME BEGAN LEAKING GAS INTO THE AIR BAG, HENCE THE ISSUE WITH THE BLOWING HORN.
