THE AIRBAG SENSOR LOCATED IN BASE OF PASSENGER SEAT IS FAULTY RENDERING THE AIRBAG NOT FUNCTIONAL. THE SENSOR IS NOT AVAILABLE FOR REPLACEMENT AND THE BOTTOM SEAT UNIT MUST BE REPLACED AT THE COST OF $7,000. AFTER RESEARCHING THE ISSUE, IT APPEARS TO BE WIDESPREAD TO THE MODEL AND YEAR. THE AIRBAG LIGHT BLINKS ON THE DASHBOARD INDICATING AN ISSUE. THE ISSUE WAS CONFIRMED AT HE INFINITI DEALER AND ALSO AN INDEPENDENT MECHANIC.

THE AIRBAG LIGHT STARTED BLINKING, I GOT IT CHECKED AND I WAS TOLD THE INFANT SEAT SENSOR WAS BAD AND ALL THE SEAT HAS TO BE CHANGED $6000. I CHECKED A COUPLE OF ONLINE FORUMS AND IT SEEMS LIKE IN THE PAST 2 YEARS PEOPLE WITH THE SAME CAR MODEL HAVE BEEN COMPLAINING ABOUT THE SAME PROBLEM. BASICALLY THE PASSENGER SEAT SENSOR IS NOT WORKING SO IT SHUTS OFF THE AIRBAG SYSTEM FOR THE PASSENGER.
AIRBAG SENSOR WAS BLINKING ON MY DASH AFTER STARTING IT IN MY DRIVEWAY TO DRIVE TO WORK. I TOOK IT IN TO AN INFINITY DEALERSHIP AND ONLY TO FIND OUT IT WAS A SEAT SENSOR TO BE REPLACE WITH ONLY 40K MILES ON THE VEHICLE. THE PART ALONE COST $6340.00 WHICH ISN'T WORTH FIXING.

AIRBAG SENSOR WAS BLINKING ON MY DASH AFTER STARTING IT IN MY DRIVEWAY TO DRIVE TO WORK. I TOOK IT IN TO AN INFINITY DEALERSHIP AND ONLY TO FIND OUT IT WAS A SEAT SENSOR TO BE REPLACE WITH ONLY 40K MILES ON THE VEHICLE. THE PART ALONE COST $6340.00 WHICH ISN'T WORTH FIXING. I WASN'T TOLD OF ANY OTHER OPTION AND SEEMS TO HAVE HAPPENED A LOT WITH OTHER OWNERS AND NO RECALL OF ANY SORT IS TO BE ISSUED.

NEED TO REPLACE EITHER OCCUPANT CLASSIFICATION SYSTEM CONTROL UNIT WHICH IS PART OF THE LOWER SEAT ASSEMBLY. COST APPROX. 4000 TO 5000 THOUSAND DOLLARS OR REPLACE AIR BAG DIAGNOSIS SENSOR UNIT WHICH IS UNDER CENTER CONSOLE. COST APPROX. 1700 DOLLARS. CANNOT TELL ME WHICH ONE TO REPLACE. CAR HAS 34000 MILES ON IT. INTERNET TELLS ME THAT THIS A COMMON PROBLEM WITH THIS VEHICLE.
AIRBAG LIGHT IS BLINKING SO TOOK TO DEALERSHIP CHARGED $149.00 AND SAID THEY CLEARED CODES...SERVICE MAN SAID THAT SOMETHING ABOUT PASSENGER SEAT NEEDED TO BE REPLACED FOR AROUND $7000.00...LIGHT HAS COME BACK ON😬
AIR BAG LIGHT RECENTLY CAME ON. I TOOK TO THE DEALER AND AFTER PAYING A DIAGNOSTIC FEE OF $170 THEY SAID "THE SEAT CUSHION NEEDS TO BE REPLACED, OCCUPANT SENSOR IS PART OF IT AND IT WOULD COST ABOUT $7,000+. WITH SO MANY SIMILAR COMPLAINTS, THIS SHOULD BE A RECALL.
THE PASSENGER AIRBAG SENSOR REMAINS OFF EVEN WHEN AN ADULT IS SITTING IN THE SEAT. INFINITE DOESN'T CONSIDER IT A SAFETY ISSUE EVEN THOUGH MANY OF THEIR G37 MODELS HAVE THIS ISSUE SO NO RECALL. THE ONLY FIX IS TO REPLACE THE SEAT FOR$6,000 OR MORE ON A CAR WORTH $8,000 NOW.

THIS IS DEFINITELY A DEFECT THAT WARRANTS A RECALL BECAUSE THERE ARE MANY, MANY OTHER COMPLAINTS ABOUT THIS SAME PROBLEM ALL OVER INTERNET. INFINITI NEEDS TO TAKE RESPONSIBILITY FOR THIS DEFECT.
