ORIGINAL OWNER OF 2017 SUBARU FORESTER WITH EYESIGHT. DRIVING ON OPEN ROAD IN CLEAR WEATHER. NOTICED A SMALL LINE ABOVE REGISTRATION STICKER THAT LOOKED LIKE A BLADE OF GRASS. STOPPED AT OUR DESTINATION AND NOTICED A CRACK THAT TRIPLED IN LENGTH IN THE 30 MINUTES IT SAT PARKED ACROSS THE LEFT LOWER SECTION OF THE WINDSHIELD. IT PROCEEDED TO SPREAD OVER THE NEXT DAY. HAVE NEVER HAD A CHIP OR IMPACT TO THIS WINDSHIELD PREVIOUSLY, BUT IF THERE WAS ANY OBJECT THAT HIT THE CAR IT WAS INCREDIBLY SMALL AS THE CRACK IS ENTIRELY IN THE DRIVER'S EYELINE AND I DID NOT SEE OR HEAR ANYTHING.

AFTER DRIVING THE CAR AND PLACING IT IN "PARK", THE KEY COULD NOT BE EXTRACTED FROM THE IGNITION. PUTTING THE CAR INTO DIFFERENT GEARS WAS OF NO HELP. I WAS SOMETIMES ABLE TO RESTART THE CAR AND THEN EXTRACT THE KEY, BUT NOT EVERY TIME. MY CHOICES WERE TO RETURN HOME OR LEAVE MY CAR IN THE PARKING LOT WITH THE KEY IN IT WHILE DRAINING THE BATTERY WHILE THIS MAY SEEM MORE AN INCONVENIENCE THAN A SAFETY ISSUE, ON SOME OCCASIONS THIS RESULTED IN MY BATTERY BECOMING SO WEAK THAT MY CAR WOULDN'T CRANK LEAVING ME STRANDED UNTIL I COULD FIND SOMEONE TO HELP ME JUMP OFF MY CAR. AFTER THREE OF THESE INCIDENTS, I BEGAN DISCONNECTING THE BATTERY CABLES WHEN I COULDN'T REMOVE THE KEY. I LOOKED ONLINE AND FOUND THAT MANY PEOPLE WERE HAVING THE SAME ISSUE WITH THEIR SUBARUS OF VARIOUS MODELS. THEY SAID THAT THE GUIDE PLATE IN THE SHIFTER ASSEMBLY WAS FAULTY. THE DEALERSHIP STATED THAT THIS WAS A COMMON PROBLEM AND THEY KEPT THOSE PARTS IN STOCK. THEY DID REPLACE THE GUIDE PLATE WHICH CORRECTED THE ISSUE. MY QUESTION IS: IF SO MANY PEOPLE HAVE THE SAME ISSUE (WITH A CORRECTION COST OF $500) WHY ISN'T THERE A RECALL? I PERSONALLY HAVE AN EXTENDED WARRANTY WHICH COVERED ALL BUT $100 OF THE REPAIR, BUT PEOPLE WHO DON'T HAVE THE EXTENDED WARRANTY WILL HAVE TO PAY THE FULL $500 JUST TO GET A KEY OUT OF THE IGNITION. IT IS MY UNDERSTANDING THAT SUBARU NOW USES A DIFFERENT GUIDE PLATE IN THE LATEST MODELS. SUBARU KNOWS THIS IS A PROBLEM IN THE CARS THAT ARE 2-3 YEARS OLD. THEY NEED TO BE HONEST WITH CONSUMERS SO THAT THEY DON'T RISK BEING STRANDED DUE TO A WEAKENED BATTERY BECAUSE OF FAULTY GUIDE PLATES AND THEY NEED TO CORRECT THE PROBLEM FREE OF CHARGE AS IT IS A SAFETY CONCERN. *TR

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.
