WE TOOK IT TO THE DEALER AND THEY SAID IT WOULD COST $170.00 TO REPLACE ONE OF THE TIRE PRESSURE SENSORS THEY SAID WERE FAULTY. NEITHER MY WARRANTY OR EXTENDED WARRANTY WOULD COVER IT. MY HUSBAND THEN PURCHASED A TIRE PRESSURE SENSOR AND TOOK IT TO A LOCAL MECHANIC SHOP FOR THEM TO REPLACE IT, WHICH HAVE COST A TOTAL OF $40.00. THE MECHANIC PUT IT ON THEIR COMPUTERS AND COULDN'T IDENTIFY A BAD SENSOR, BUT SOMETHING SHOWING WRONG IN ONE OF THE COMPUTERS READING THE SENSOR. WE ARE GOING TO HAVE TO TAKE IT BACK TO THE DEALER AND TRY TO GET THIS RECTIFIED. IF IT IS A COMPUTER THEN I FEEL IT IS A SAFETY ISSUE SINCE WE CAN NOT GET AN ACCURATE READING AND THE TIRE PRESSURE LIGHT IS STAYING LIT UP ON THE DASHBOARD.

THE FOLLOWING AFTERNOON, THE CHIP HAD BECOME A LARGE CRACK THE CAME DOWN FROM THE TOP OF THE WINDSHIELD NEARLY HALFWAY DOWN THE WINDSHIELD. I PAID THE EXTRA MONEY TO REPLACE THE WINDSHIELD WITH OEM GLASS. MORE RECENTLY (LESS THAN 1.5 YEARS LATER), THE WIPER BLADES ON MY WINDSHIELD WERE REPLACED. THE ONE WIPER BLADE WOULD NOT LET GO AND THE BLADE CAME BACK DOWN ON THE WINDSHIELD WITH THE SPRING. NO MARKS WERE OBSERVED IN THE WINDSHIELD. THE FOLLOWING AFTERNOON, A CRACK CAME UP FROM THE BLADE AND RAN ACROSS NEARLY 1/3 OF THE WINDSHIELD. THE DATE RECORDED IS FOR THE SECOND INCIDENT.

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.
