PREVIOUSLY THE PASSENGER OCCUPANCY SENSOR WAS OVERLY SENSITIVE. SOMETIMES EVEN AN IPAD ON THE FRONT PASSENGER SEAT WOULD BE DETECTED AS A "PASSENGER". BUT RECENTLY IT'S JUST GONE TO THE OPPOSITE EXTREME. THE PASSENGER AIR BAG LIGHT WILL STILL BE "OFF" EVEN IF A REAL PASSENGER SITS THERE.

WHILE 2017 FORESTER IN MOTION (BOTH INSTANCES OCCURRED AT HIGHWAY SPEED) SRS RED WARNING LIGHT IN DRIVERS DASHBOARD COMES ON. ALSO AIRBAG INDICATOR AT MIDDLE TOP INFORMATION SECTION CHANGES FROM PASSENGER AIRBAG ON TO PASSENGER AIRBAG OFF. THIS HAPPENS EVEN THOUGH THERE IS A PASSENGER IN THE SEAT. THIS EVENT HAS OCCURRED ON TWO OCCASIONS - NOV 2018, AND JUN 2019. IN BOTH INSTANCES THE ISSUE RESOLVED AFTER A FEW DAYS BUT BEFORE SUBARU SERVICE COULD BE SCHEDULED TO REVIEW THE ISSUE. SUBARU SERVICE DEPT SAID THE ISSUE WAS CAUSED BY ELECTRICAL INTERFERENCE FROM A CELL PHONE ON THE SEAT. HOWEVER, NO ELECTRONIC DEVICES WERE ON THE SEAT AT THE TIME OF INCIDENTS. THE SEAT HAVE NEVER GOTTEN WET EITHER.

2017 FORESTER SRS AIRBAG SENSOR DEFECTIVE TWO YEARS AFTER PURCHASE, THE SRS AIRBAG WARNING LIGHT APPEARED. THIS LIGHT FLICKERS ON AND OFF, AT RANDOM, WHETHER OR NOT A PASSENGER IS IN THE SEAT. (NO PASSENGER WILL BE DRIVING WITH ME UNTIL THIS IS REPAIRED.) MY SUBARU DEALERSHIP SERVICE MANAGER TOLD ME THAT THERE WAS A RECALL (HE MISSPOKE, PERHAPS HE MEANT 'SHOULD BE') AND SAID THAT HE "SEES THIS ALL THE TIME". HE IMMEDIATELY KNEW (PRIOR TO TESTING IT) THAT THEY WOULD BE REPLACING THE PASSENGER SEAT BOTTOM, FOR A NEW SENSOR PAD. HE SAID THEY ARE USUALLY BACKORDERED. BACKORDERED INDICATES TO ME THAT THERE IS A HIGH DEMAND TO CORRECT THIS ERROR IN THIS CRITICAL SAFETY SYSTEM. AT THIS POINT, I HAVE SUBARU CORPORATE INVOLVED; I'VE EMAILED AND SPOKEN AT LENGTH WITH KRIS DRECHSEL, A SUPERVISOR IN CUSTOMER SERVICE, AND CHARLES HOSIER, A CUSTOMER SERVICE ADVOCATE. WHILE THEY BOTH WERE SUPERB IN THEIR INTERACTIONS WITH ME, I LEARNED NOTHING ABOUT WHAT SUBARU IS DOING OR INTENDS TO DO ABOUT THIS REPREHENSIBLE SITUATION, OTHER THAN PASS ALONG MY COMPLAINT. I WAS EMAILED THAT THEY ARE "NOT AWARE OF ANY TRENDING ISSUE WITH THE PASSENGER SIDE SEAT SENSOR". SUBARU IS CLEARLY AWARE THERE IS A PROBLEM AND IS NEGLECTFUL IN NOT BEING FULLY TRANSPARENT WITH OWNERS THAT THERE IS THE POTENTIAL THAT AN AIRBAG MAY NOT DEPLOY IN A COLLISION DUE TO THIS SENSOR DEFECT. SUBARU NOTED THAT THEY RELY ON CUSTOMER FEEDBACK AND THAT THE APPROPRIATE PROTOCOL WILL BE FOLLOWED FOR SUCH COMPLAINTS. CONSIDERING THE GRAVITY OF THIS ISSUE, I ASSUME, THEN, THAT I AM THE ONLY CUSTOMER WHO HAS PROVIDED THIS COMPLAINT AND THAT THEY ARE NOW GOING TO DISCOVER THE 'TREND' AND PROVIDE NOTICE OF THIS SRS AIRBAG DEFECT TO THE PUBLIC. THERE ARE 25 COMPLAINTS ON THIS SITE ALONE (OF HOW MANY THAT "MAY APPEAR"?), COUNTLESS ONLINE FORUMS, AND APPARENTLY LAW SUITS PENDING. IS A DEATH WHAT'S PREREQUISITE HERE?

19V701000 · Air Bags:sensor:occupant Classification

Oct 3, 2019

Subaru of America, Inc. (Subaru) is recalling certain 2015-2018 Forester vehicles equipped with heated seats. An electrical connection in the front passenger seat for the Occupant Detection System (ODS) may loosen.

Consequence & remedy

Consequence: If the connection loosens, the front passenger airbag may deactivate even though the seat is occupied, increasing the risk of injury to the front passenger in the event of a crash.

Remedy: Subaru will notify owners, and dealers will inspect and, as necessary, replace the ODS sensor mat harness, free of charge. The recall began February 11, 2020. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUM-98.

PE19009 · Occupant Detection System (ods) Failure

Opened Aug 6, 2019 · Closed Jan 22, 2020

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Air Bags:frontal:passenger Side:inflator Module; Air Bags:sensor:occupant Classification

The Office of Defects Investigation (ODI) opened PE19-009 to investigate 51 complaints and additional Early Warning Report (EWR) data related to allegations of front passenger seat Occupant Detection System (ODS) malfunctions in model year (MY) 2016 through 2018 Subaru Forester vehicles. These vehicles use a capacitive type ODS, which is intended to classify the occupant of the passenger seat as either full-sized, small stature, a child seat or other object. The complaints reported the ODS failed to operate properly, the SRS (Supplemental Restraint System) warning light illuminated, and/or the ODS incorrectly suppressed (turned off) the front passenger air bag when the seat was occupied by a full-sized passenger. In a frontal crash that is sufficient to warrant deployment, a suppressed air bag may increase the risk of injury to the occupant of the seat.On August 14, 2019 ODI sent an Information Request (IR) to Subaru requesting information on the subject vehicles and MY 2014-2015 Subaru Forester vehicles.On October 3, 2019, Subaru submitted a Defect Information Report (DIR) to NHTSA describing a safety defect in the passenger-side front airbag Occupant Detection System (ODS) harness of 366,282 MY 2015-2018 Subaru Forester vehicles equipped with seat heaters.The DIR stated that over time, due to a decrease in contact pressure between the terminals in the ODS sensor mat harness, a temporarily unstable electrical connection may be possible. If the connection is temporarily unstable, the ODS may not properly determine the status of the right front seat occupant. If the ODS is unable to correctly determine the status of the front occupant, the airbag warning light may illuminate, and the front passenger airbag may deactivate even though the seat is occupied, increasing the risk of injury to the front passenger in the event of a crash.Using vehicle production data and field occurrence frequency, Subaru determined the potentially affected vehicle production range to be between January 20, 2015 ?and August 1, 2017.In addition, Subaru indicated that over 99 percent of the related MY 2015-2018 field reports with vehicles in the production range involved vehicles with seat heaters.NHTSA's analysis of complaint and warranty claim data showed 1,440 of the complaints and 11,672 of the claims involve vehicles with seat heaters that were built within the production range covered by Subaru's recall.In addition, NHTSA's analysis showed a complaint rate of 393.1 per hundred thousand vehicles for the recalled population and 89.0 for MY 2014 through 2018 vehicles that are not included in the recall. Analysis of warranty claim data found a claim rate of 3.2 percent for the recalled population and 0.3 percent for MY 2014 through 2018 vehicles that are not included in the recall.Subaru will instruct owners with Subaru Forester vehicles produced in the affected vehicle production range, to bring their vehicles to a dealer to have the sensor mat harness, inspected and replaced with a new part, including the seat cushion assembly, if necessary.Based on ODI's analysis, the actions taken by Subaru mitigate any unreasonable risk to safety posed by ODS sensor mat failures in the subject vehicles. For subject and peer vehicles outside the recall population and those equipped without seat heaters, ODI's analysis indicates that there is currently no safety-related defect trend. Given these circumstances, further use of the agency resources in this matter does not appear to be warranted. Accordingly, this investigation is closed.
