I HAVE A 2009 INFINITI G37 WITH 89000 MILES, JUST RECENTLY THE AIR BAG LIGHT STARTED FLASHING FOR NO APPARENT REASON. I TOOK IT TO THE INFINITI DEALER AND WAS TOLD IT WAS THE PASSENGER AIR BAG SENSOR IN THE FRONT PASSENGER SEAT THAT WAS BAD, AND WOULD COST OVER $6K TO FIX. MY RESEARCH SUGGESTS THIS IS A KNOWN SAFETY ISSUE AND A COMMON PROBLEM WITH INFINITIS THAT SHOULD BE RECALLED AND CORRECTED BY NISSAN CORP.

THE AIRBAG LIGHT STARTED BLINKING. I TOOK IT INTO THE DEALERSHIP AND THEY SAID THERE WAS AN ISSUE WITH THE PASSENGER SEAT OCCUPANCY SENSOR; THEY NEED TO REPLACE THE ENTIRE PASSENGER SEAT. THEY SAID THE AIRBAGS WILL NOT DEPLOY AT THIS TIME AND TOTAL COST OF REPAIRS WILL BE APPROX $8000. I WAS TOLD THIS WAS "JUST SOMETHING THAT HAPPENS" BUT WHEN I SEARCHED ONLINE HUNDREDS OF PEOPLE HAVE THE SAME COMPLAINT! THIS ISN'T LIKE REPLACING BRAKES THAT HAVE WORN DOWN; I'VE NEVER USED THE AIRBAGS. AND UNLESS I PAY $8K FOR A KNOWN MALFUNCTION, THEY WON'T DEPLOY IN AN ACCIDENT AND THE VEHICLE HAS LOST ALL RESALE/TRADE-IN VALUE.
