167 reportsAIR BAG LIGHT RECENTLY CAME ON. I TOOK TO THE DEALER AND AFTER PAYING A DIAGNOSTIC FEE OF $158 THEY SAID "THE SEAT CUSHION NEEDS TO BE REPLACED, OCCUPANT SENSOR IS PART OF IT AND IT WOULD COST ABOUT $5,000+. WITH SO MANY SIMILAR COMPLAINTS, THIS SHOULD BE A RECALL.

I WAS ON THE HIGHWAY TRAVELING ABOUT 60-65 MPH AND A TRUCK MERGED, I SLOWED THEN DECIDED TO PASS AS IT WAS A LARGER TYPE TRUCK AND SLOW TO MERGE, WHEN I STEPPED ON THE GAS...NOTHING HAPPENED. THE VEHICLE SEEMED TO HAVE GONE INTO NEUTRAL LIKE SPACE AND I HAD NO GEAR AND I WAS HALF IN THE PASSING LANE. I HAVE AN AUTOMATIC TRANSMISSION. I TOOK MY FOOT OFF THE GAS AND IT FINALLY APPEARED TO CATCH, BUT I THOUGHT I WAS GOING TO CRASH. I DID HAVE SHIFT AND LAG ISSUES AND JUST GOT A TCM UPDATE 05/25/2019 WHICH APPEARS TO HAVE SOLVED THE OTHER PROBLEMS, BUT I AM AFRAID TO PASS ON THE HIGHWAY BECAUSE I AM NOT SURE IF THIS ISSUE WAS THE SAME AS THE LAGGING AT LOWER SPEEDS AND ROUGH DOWNSHIFTING.
B1018 DTC CODE FOR A FAILED OCCUPANCY SENSOR. MANY MANY REPORTED FAULTS AND INFINITI CHOOSES TO IGNORE THE SERIOUS PROBLEM. IN MOST CASES, THE REPAIR IS $6,000+. SOMETIMES 80-90% OF TRUE VEHICLE'S MARKET VALUE.

PASSENGER OCCUPANCY SENSOR IS KNOWS TO FAIL ON THESE CARS, AND THE AIRBAG WILL NOT DEPLOY BECAUSE THE COMPUTER DOESNT KNOW IF ANYONE IS SITTING IN THE SEAT. THE REPAIR COSTS 60-80% OF VEHICLE'S VALUE, AND NOT FEASIBLE FOR ANY SANE INDIVIDUAL TO PAY FOR THIS FAULTY SENSOR. NISSAN/ INFINITI FAIL TO TAKE RESPONSIBILITY FOR THIS FA…

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.
AIRBAG PASSENGER SEAT SENSOR IS FAULTY. AIRBAG SYSTEM REMAINS OFF EVEN WITH NO ONE IN THE SEAT. THERE ARE HUNDREDS OF PEOPLE ON FORUMS REPORTING THE SAME PROBLEM. DEALER SUGGESTED REPLACING THE ENTIRE SEAT FOR $10,000. THIS IS A SAFETY ISSUE THAT NEEDS TO BE RECALLED.
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 …

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.
THE SEATBELT LIGHT STARTED FLASHING AND WONT TURN OFF.
