APPROXIMATELY 3/1/08, MY 2005 350Z AIRBAG SENSOR LIGHT STARTED FLASHING. I TOOK IT TO THE DEALER ON 3/8/10 WHERE I PURCHASED IT. TECH VERIFIED FAILURE CODE B1129 RH SIDE MODULE. REPLACED WITH YHEHM-CD000 MODULE ASSY-SIDE. LIGHT WAS CLEARED. THEN APPROXIMATELY 10/1/10, AGAIN THAT SENSOR LIGHT STARTED TO FLASH. I TOOK IT INTO THE SAME DEALERSHIP WHERE I PURCHASED MY NEW CAR ON 10/6/10 (7 MONTHS LATER). TECH DIAGNOSED FAILURE CODE B1134 LH SIDE AIR BAG MODULE FAILURE. REPLACED WITH YHEHA-CD000. LIGHT WAS CLEARED. ON NOV 20, 2010, I HYDROPLANED IN THE RAIN, HIT A GUARD RAIL HEAD ON, DID A 1080 (360 DEGREES X 3) THEN HIT A TREE ON THE RIGHT SIDE. MY AIRBAGS DID NOT DEPLOY AND AFTER THE POINT OF IMPACT, THAT SAME SENSOR LIGHT STARTED TO FLASH ON THE DASH. I FILED A COMPLAINT WITH NISSAN CONSUMER AFFAIRS (1800 NISSAN1) OPTION 7 THEN OPTION 3. THEY HAD A TECHNICIAN/ENGINEER COME OUT TO PERFORM AN INSPECTION, AFTER ABOUT 4 WEEKS WAITING FOR A RESPONSE FROM THEM (I CALLED NUMEROUS TIMES ASKING ABOUT AN UPDATE) I RECEIVED A PHONE CALL FROM MY [XXX]STATING THAT THE TECHNICIAN FOUND EVERYTHING IN WORKING ORDER. I THINK THAT THE TECH SHOULD HAVE FOUND AN ERROR CODE BECAUSE OF THE FLASHING SENSOR LIGHT. THERE SHOULD BE A RECALL ON THIS VEHICLE. I WAS WEARING MY SEATBELT AND I HAD ONLY MINOR INJURIES BUT STILL THIS SHOULD BE CONSIDERED A LEMON BECAUSE ITS SAFETY RELATED AND WAS "FIXED" TWICE AND STILL DID NOT FUNCTION WHEN I REALLY NEEDED IT TO. I DID NOT HAVE MY CELL UNTIL MY WIFE DROVE OUT
