NHTSA Complaint #11170171 — 2012 INFINITI G37

I BROUGHT IN MY 2012 FOR MAINTENANCE AT AN INFINITI SERVICE DEALER. I RECEIVED A "NEW" BATTERY AS I WAS TOLD THE BATTERY NEEDED REPLACEMENT SOON. COME TO FIND OUT, THE "NEW" BATTERY WAS ACTUALLY A FAULTY COMPONENT AND MY CAR WOULD NOT START. I BROUGHT IT IN FOR DIAGNOSTICS AND THEY SAID NOTHING WAS WRONG. I TOLD THEM THAT IT MUST BE THE BATTERY SINCE I NEVER HAD THAT ISSUE BEFORE. THE BATTERY ISSUE CONTINUED AND I WOULD HAVE TO JUMP MY CAR OFF. THE DAY I HAD TO BRING IT BACK TO INFINITI, I HAD TO JUMP OFF THE CAR AND RIGHT AFTER I DID, THE AIRBAG LIGHT BEGAN FLASHING AND CODES INDICATED A FAULTY DIAGNOSIS SENSOR UNIT FOR THE AIRBAG. THEY THEN DID THEIR DIAGNOSTICS AGAIN AND DETERMINED THAT THE BATTERY ITSELF WAS THE PROBLEM IN THE CAR-STARTING ISSUE, YET THE INFINITI BAG LIGHT CONTINUED TO BLINK. THE DEALER SAID THE COST WOULD BE $1600 TO REPLACE THE SENSOR/CONTROL UNIT. THE AIRBAG HAS NEVER BEEN DEPLOYED AND I NEVER HAD ISSUES UNTIL THE BATTERY REPLACEMENT WITH A FAULTY BATTERY AND THUS CREATING THE NEED TO JUMP START THE VEHICLE. THE LIGHT CAME ON RIGHT AFTER A JUMP START. I NEVER SAW THE LIGHT BEFORE THAT.
