2006 BMW 7 SERIES Seats Problems

I PURCHASED THE CAR FROM A DEALER IN VIRGINIA. MAYBE A FEW WEEKS LATER THE AIRBAG WAARNING LIGHT CAME N THE SCREEN. I HAVE NOT BEEN ABLE TO DRIVE IT BECASUE WHEN I WENT TO TAKE IT TO GET LOOKED AT BY A BMW REPAIR PERSON TOLD ME THAT THERE WAS A RECALL ON THAT SAME ISSUE AND THE DEALER SHOULD NOT HAVE SOLD ME THE CAR WITHOUT TELLING ME THAT INFORMATION. HE THEN TOLD ME IT IS THE ( SEAT OCCUPANCY DETECTOR PASSENGER SIDE AND RESISTENCE TO HIGH FIRING CIRCUIT , BELT TENSIONER PASSENGER SIDE. HE SAID TO CALL BMW SO I DID AND THEY TOLD ME THAT THE RECALL REPAIR TIME EXPIRE A YEAR BEFORE I PURCHASED THE CAR . NO ONE EVER SHARED THIS INFORMATION WITH ME AND NOW IT IS NOT SAFE TO HAVE MY KIDS OR HUSBAND IN THE PASSENGER SEAT BECAUSE OF THIS PROBLEM.....

TROUBLE LIGHT SHOWS-- PASSENGER RESTRAINT SYSTEM. MY MECHANIC DIAGNOSED IT AS A DEFECTIVE SEAT MODULE SENSOR IN THE FRONT PASSENGER SEAT. HIS COST OF REPAIR IS $1,200 WITH NO ASSURANCES THAT THE PROBLEM WILL BE RESOLVED DUE TO THE TAKATA AIR BAG RESPONSE TO THIS SENSOR.
