2009 Infiniti EX Electrical System Problems

I TOOK THE CAR TO JIM COLEMAN INFINITI SERVICE DEPARTMENT TO FIND OUT WHY THE AIR BAG WARNING LIGHT IS FLASHING NON-STOP. AFTER THE DIAGNOSTIC THEY CONCLUDED IT WAS DUE TO PASSENGER SIDE OCS SENSOR FAULTY, SO IN ORDER TO REPLACE THE SENSOR THEY NEED TO REPLACE THE ENTIRE PASSENGER SEAT DUE TO SENSOR EMBEDDED IN THE SEAT AND ASKING FOR AROUND $4500 FOR PARTS AND $600 FOR LABOR. IT'S OUTRAGEOUS! ALTHOUGH I BOUGHT THE CAR AT 2009 I HARDLY DRIVE THE CAR AND TOOK METRO TO WORK MOST OF THE TIME SO THE MILEAGE IS ONLY <50K. AFTER I DID A RESEARCH ON THE WEB I DISCOVERED THAT THE 2007, 2008 INFINITI EX35 MODEL ALL HAVE THE SAME EXACT PROBLEM THAT RESULTED A RECALL. PER NHTSA, A SENSOR LOCATED IN THE PASSENGER SEAT CUSHION "MAY HAVE BEEN MANUFACTURED OUT OF SPECIFICATION. UNDER CERTAIN CONDITIONS, THIS COULD CAUSE AN INTERRUPTION OF SIGNAL BETWEEN THE OCS [THE OCCUPANT CLASSIFICATION SYSTEM -- WHICH ACTIVATES THE AIRBAG WHEN THE PASSENGER SEAT IS OCCUPIED] AND THE AIRBAG CONTROL UNIT. THIS COULD RESULT IN THE PASSENGER AIRBAG BEING SUPPRESSED, WHICH COULD FAIL TO PROVIDE ADEQUATE PROTECTION IN THE EVENT OF A CRASH." IT APPEARS THAT INFINITI DID NOT FIX THE PROBLEM FOR THE 2009 MODEL WHICH WAS PROBABLY ALREADY ON THE SALES LOT AND AS LONG AS THERE'S NO WARNING LIGHT FLASHING THEY ASSUME NO SENSOR PROBLEM BUT THE UNDERLYING SENSOR DEFECT STILL EXIST AND WAITING TO ERUPT. I SHOULD NOT HAVE TO PAY FOR INFINITI'S OBVIOUS DESIGN/MANUFACTURED SENSOR DEFECT ESPECIALLY IT IS THE WELL-KNOWN SENSOR DEFECT THAT CAUSE THEIR 2008 RECALL (HTTPS://CARS.USNEWS.COM/CARS-TRUCKS/DAILY-NEWS/081016-URGENT-RECALL-ALERT-NISSAN-INFINITI-RECALLING-200-000-VEHICLES-FOR-AIRBAG-DEFECT). PLEASE ADVISE WHAT I CAN DO TO MAKE INFINITI TO BE RESPONSIBLE FOR FIXING THE SAME DEFECT FROM THE 2008 RECALL AT NO CHARGE TO THE CUSTOMER DECEIVED BY THEM? THANK YOU VERY MUCH.
