BEFORE ENTERING FREEWAY, AT LOW SPEED, A CRACK APPEARED ON THE WINDSHIELD. SEEMS TO STEM FROM THE LOWER BLACK STRIP ON THE WINDSHIELD. THERE IS A SMALL IMPACT POINT STEMMING FROM THE BLACK STRIP ALONG THE LOWER SIDE OF THE WINDSHIELD AND THE CRACK IMMEDIATELY GREW TO ABOUT 10'' VERTICALLY UPWARD FROM THAT. THE NEXT DAY, THE CRACK CURVED AND GREW ANOTHER 10-15'' IN LENGTH ACROSS THE PASSENGER SIDE. I DID NOT NOTICE ANYTHING IMPACT THE WINDSHIELD. A CAR WAS AHEAD OF ME BUT WAS ABOUT 2-3 CAR LENGTHS AHEAD AT LOW SPEED AS IT WAS A FRONTAGE ROAD BEFORE ENTERING THE FREEWAY RAMP.

I WAS DRIVING THE VEHICLE WHEN A CAR PASSED ME. THE SOUND OF THE ROCK STRIKE WAS BARELY NOTICEABLE AND I DIDN'T NOTICE THE DAMAGE UNTIL MY PASSENGER POINTED IT OUT TO ME. SUBARU WINDSHIELDS ARE TOO FRAGILE AND BREAK EASILY WHICH IS A SAFETY RISK. I WILL BE REPLACING THIS SECOND SUBARU WINDSHIELD WITH AFTERMARKET GLASS.

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.
