2017 Subaru Forester

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.

Airbag sensor does not work. It is not activated when someone sits in the passenger seat. This was recalled in other Subaru Foresters but for some reason our specific vin number is not eligible for repair.

My 2017 Subaru Forester is experiencing the exact component failure and severe safety hazard outlined in NHTSA Recall 19V-701 (Subaru Campaign WUM-98R). The front passenger seat Occupant Detection System (ODS) is failing continuously, which illuminates the "Passenger Airbag Off" indicator and completely deactivates the front passenger airbag safety restraint system even when an adult is securely seated. Because my specific VIN was omitted from the recall population list, my local Subaru dealership refused to perform the recall repair, stating no active campaign exists for my vehicle. As a result, I have driven this vehicle for over a year with a completely disabled, non-functioning passenger airbag system. Upon researching the technical service bulletins for WUM-98R, my vehicle perfectly matches all manufacturing, model year, and component criteria for the defective occupant detection wiring harness. The omission of my VIN from this safety campaign is an error that has left a severe, life-threatening manufacturing defect unaddressed. I am filing this complaint to urge the NHTSA to investigate VIN exclusions for this campaign and force an expansion of Recall 19V-701 to protect impacted consumers.

The passenger airbag Occupant Detection System (ODS) has failed on my 2017 Subaru Forester (VIN: [XXX]) at 78,255 miles. This failure completely deactivates the front passenger airbag, creating an immediate, severe safety hazard for any front-seat passenger. This vehicle previously had Federal Safety Recall WUM-98 performed in 2020 to resolve this exact ODS engineering defect. However, the safety recall remedy has failed. The red SRS/airbag warning light is permanently illuminated, and the passenger airbag indicator status remains stuck on "OFF" even with an adult seated in the vehicle. A diagnostic scan performed on XXX by Lithia Subaru of Oregon City confirmed active code DTC B1760 (Occupant Detection Sensor Mat Malfunction). I was forced to pay a $100.00 diagnostic fee just to retrieve my vehicle, and the dealership quoted an additional $2,171.12 ($1,371.12 for parts and $800.00 for labor) to replace the entire passenger seat bottom cushion assembly and harness (Part 64084SG23A) to resolve the failed internal sensor. The dealership attempted to claim the seat got wet to excuse the failure, but the seat is bone dry and has never sustained any liquid spills, window leaks, or detailing. According to Subaru’s official technical service bulletin filed with the NHTSA (Document MC-XXX, Page 8, Step 6), the manufacturer explicitly documents that if DTC B1760 persists or returns after the recall harness is installed, the proper factory remedy is to replace the seat cushion assembly. Because the original safety recall failed to permanently resolve the safety defect, and the dealer is refusing to repair this deactivated safety system without a massive out-of-pocket consumer charge—after already charging a fee to diagnose a known, recurring safety defect—I am requesting an investigation into failed safety recall remedies for this vehicle generation.

The shift guide plate in my 2017 Subaru Forester failed, causing the ignition key to become stuck and not release when the engine is off. The component is available for inspection upon request. The failure was confirmed by a Subaru dealer, who diagnosed the defective shift guide plate and provided a repair estimate of $685.23. The safety risk is significant - an inability to remove the key from the ignition can prevent the driver from securing the vehicle and creates confusion about whether the engine is truly off. There were no warning lamps or messages prior to the failure. The problem presented suddenly and has been reproducible consistently since it first appeared. This is a known manufacturing defect. Subaru acknowledged it by issuing an 8-year extended warranty extension (TSB 16-112-18R) specifically covering this component. My vehicle has only 71,000 miles - well below average for a 9-year-old vehicle - and falls just outside the 8-year window. I contacted Subaru of America requesting goodwill assistance, which was denied with no explanation beyond the warranty expiration. I am filing this complaint to establish an official record of this defect and the manufacturer's failure to stand behind it.

My 2017 had the passenger airbag sensor recall in 2020. It went into for repair. It began going off again where the passenger seat airbag is off when a passenger is in the seat in 2023 on and off. It consistently began going off again in August 2024. I spoke to subaru corporate and they said they needed to replace the whole seat and wouldn't cover the cost of the whole repair of 1600. The part had a long backorder because so many cars are affected. I didn't receive a new part until June 2025. The local dealer replaced the seat. Now not even a year later the passenger airbag sensor is off with a passenger. This is our only car that fits our whole family and my family has to sit in the seat. This is a massive safety issue that Subaru is not taking responsibility for ongoing repairs even after the 2020 recall. I'm extremely concerned for the safety of my passengers.

I own a 2017 Subaru Forester with approximately 55,324 miles. The vehicle has experienced repeated rear wheel bearing failures at relatively low mileage. On October 1, 2024, at 48,877 miles, the passenger-side rear wheel hub assembly, including the wheel bearing, was replaced by a Subaru dealership. Subaru provided goodwill assistance for that repair. At approximately 55,324 miles, both rear wheel bearings were diagnosed as failed and required replacement. The failure was confirmed by a Subaru dealer and an independent repair facility. Manufacturer was contacted regarding assistance but declined coverage support. Consequently this most recent repair was performed by independent repair shop. Prior to replacement, the vehicle exhibited increasing humming, roaring, and grinding noises from the rear, which worsened with vehicle speed. No warning lights were illuminated. I am concerned about repeated premature rear wheel bearing failures and the potential safety risk associated with wheel bearing deterioration, including loss of wheel stability and vehicle control if the condition progresses while driving.
