2012 INFINITI M37

The front passenger airbag warning light came on with a dash warning flashing light. I isolated the fault to the passenger seat weight sensor, which prevents the airbag from deploying when a passenger of less than 90 pounds is sensed in the front seat. The time from the onset of the warning light to discovery of the actual fault was less than a week and this was facilitated by a mechanic with a sophisticated enough OBD reader to flesh out Infiniti codes. I called my local Infiniti dealer in Tacoma, WA and they were able to supply a part number but it has been discontinued for the 2011-2013 Infiniti M37 models. Without this sensor working, the passenger airbag may not deploy in the event of a collision, and that is unsatisfactory/downright unacceptable. These cars will operate for 20 plus years and are otherwise engineered to last 200/000 miles. I have 90,000 miles on the odometer and the car is otherwise in great shape, but I may be forced to scrap it if I can't resolve the weight sensor malfunction.

Passenger Air Bag Sensor Failed. Concerned Passenger Airbag will not deploy when passengers are in the car. This is a Very Known and Problematic issue with Infiniti and Infiniti will not address this critical safety issue. Infiniti says repairs would be the owner responsibility and cost in excess of $8,000. This is a critical safety issue and needs to be addressed by Infiniti before someone gets hurt.

airbag light blinks. We tried the reset and it worked until someone sat in the seat. Called dealer and they said the seat bottom needs replacing as it’s a occupancy sensor. Cost for part + labor = 5K .. Totally outrageous. safety issue

THE FRONT PASSENGER AIRBAG LIGHT WENT ON IN MY 2012 INFINITI M-37 UPON STARTING IT THE MORNING OF 10/09/2020. I BROUGHT IT INTO MY LOCAL TAMPA INFINITI DEALERSHIP ON 10/21/2020 WHERE I PURCHASED THE CAR AND HAVE HAD OVER 90% OF THE SERVICING COMPLETED. MY SERVICE ADVISOR MICHAEL ENGLISH EXPLAINED TO ME THAT IT WOULD COST OVER $7104 TO REPLACE THE BOTTOM OF THE FRONT PASSENGER SEAT. IN ADDITION A DIAGNOSTIC SENSOR WOULD LIKELY NEED TO BE REPLACED AT A COST OF $450. HE ALSO TOLD ME THAT THIS PROBLEM IS ONE THAT OCCURS IN A NUMBER OF INFINITI AUTOMOBILES OF THIS TYPE. HE WAS SORRY THAT IT WAS NOT COVERED BY ANY WARRANTY AND THAT IT DIDN'T SEEM FAIR THAT A RECALL WASN'T AVAILABLE TO REMEDY THE SAFETY PROBLEM. MY CAR HAS ONLY 120,000 MILES ON IT AND RUNS VERY WELL AND IS WORTH ABOUT $8000 AS A TRADE IN BUT NOT WITH A FAULTY PASSENGER SEAT SAFETY HAZARD. I CAN'T AFFORD TO FIX THIS PROBLEM THAT COST NEARLY AS MUCH THE CAR IS WORTH. HOW COULD INFINITI MAKE OR DESIGN A SEAT WITH AIR BAG SENSORS THAT CANT BE REPAIRED WITHOUT HAVING TO REPLACE THE ENTIRE SEAT? THIS IS THE RESULT OF POOR ENGINEERING AND IS A PRODUCT SAFETY HAZARD FORCING MANY CONSUMERS TO CHOOSE BETWEEN HAVING SAFETY EQUIPMENT OR DOING WITHOUT BECAUSE OF THE HIGH EXPENSE TO REPAIR. I'VE NEVER HAD AN ACCIDENT TO DEPLOY THE AIRBAGS AND MY CAR HAS ALWAYS BEEN GARAGE KEPT AND PROPERLY MAINTAINED. THIS IS A MANUFACTURER DEFECT AND THERE SHOULD BE A REMEDY FOR ALL THOSE OWNERS OF THIS TYPE OF VEHICLE. I HAVE NOTICED THERE ARE MANY OWNERS OF SIMILAR INFINITI VEHICLES THAT HAVE HAD A SIMILAR PROBLEM.
