AIR BAGS

2 complaints

I AM CONCERNED ABOUT THE PASSIVE RESTRAINTS(AIR BAGS) THAT WERE USED IN THE 1991, INFINITI, Q45. AFTER DOING SOME RESEARCH I HAVE DISCOVERED THAT IN NUMEROUS ACCIDENTS THE AIR BAG FAILED TO DEPLOY, AND INJURIES RESULTED. ADDITIONALLY, I HAVE UNCOVERED THAT INFINITI IS AWARE OF THE PROBLEM, YET A RECALL WAS NEVER ISSUED. IN INFINITI'S OWE IN HOUSE BULLETINS IT IS LISTED THAT THERE IS A PROBLEM WITH THE "CRASH ZONE SENSOR." ALSO REFERENCE IS MADE REGARDING A "PINS IN CONNECTOR FOR BETTER CONTACT" AND THE AIR BAG HARNESS. WHY HASN'T A RECALL BEEN ISSUED? FORTUNATELY I HAVE NOT BEEN INVOLVED IN AN ACCIDENT IN THE THIRTEEN YEARS THAT I HAVE OWED MY 1991 INFINITI Q45. HOWEVER, NOW I AM NOW WORRIED. SINCE I HAVE NOT PERSONAL EXPERIENCED THIS PROBLEM AND YOU HAVE A REQUIRED FIELD I HAVE USED THE DATE MY CAR WENT INTO ACTIVE SERVICE. *LA
