2018 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.

Discovered (06/08/26) that the engine would not turn over without the accelerator being pushed down when warm from driving after resting 30-60 minutes. Car was taken to Capital Subaru. No codes were triggered. The throttle body was cleaned. No change. The Crankshaft Position Sensor was replaced, the ECU was reprogrammed, then the EVAP Purge Valve was replaced. A bottle of fuel injector cleaner was added to the gas tank by the dealership mechanics. No improvement. Then both CAM sensors were replaced. No improvement. All with no effect. Finally the injectors were pulled and a rail pressure test was conducted. The injectors were not holding pressure for more then 2-3 minutes. The warm start issue was fixed when the injectors were replaced on July 31, 2026.

- The passenger-side Occupant Detection System (ODS) sensor, which is part of the Supplemental Restraint System (SRS) airbag system, has failed. This component was previously replaced under a Subaru safety recall completed in May 2020. The SRS airbag warning light is now illuminated again, indicating a failure of the same system. The vehicle and failed component are available for inspection upon request. - The failure of the ODS sensor directly impacts the functionality of the passenger airbag system. This creates a significant safety risk because the airbag may not deploy correctly—or at all—in the event of a crash. This puts both the driver and any passenger at increased risk of serious injury or death. Since this is a critical safety system, its failure compromises the overall crash protection of the vehicle. - The issue is indicated by the illuminated SRS airbag warning light and has been identified as related to the Occupant Detection System. A dealership has confirmed that the ODS sensor requires replacement. The failure is consistent with known issues related to the prior recall repair. - I contacted Subaru of America regarding this issue, but they declined to provide assistance. It has not been inspected by police or insurance representatives, as no accident has occurred. - The SRS airbag warning light illuminated. There were no prior symptoms before the warning light appeared. The light has remained on consistently since then, indicating a persistent fault in the airbag system. - This issue is especially concerning because the component that failed was previously replaced under a safety recall. A recall repair should resolve a safety defect, not temporarily mask it. The failure of a critical airbag system component only a few years after a recall repair suggests that the original remedy may not have been a permanent fix. This raises serious safety concerns not only for my vehicle but potentially for other vehicles that received the same recall repair.

I brought my vehicle to an authorized Subaru dealership (Byers Imports, LLC in Columbus, Ohio) to diagnose the reason for the airbag warning lamp illuminating. The dealer had the manufacturer's WUM-98 Safety Recall (NHTSA Campaign Number 19V701000) performed to remedy a defective Occupant Detection System (ODS) sensor harness.Despite the recall remedy being completed, the Supplemental Restraint System (SRS) airbag warning light re-illuminated on the dashboard, completely disabling the front passenger-side airbag.The dealership confirmed that the passenger-side airbag remains completely disabled and inoperable due to a hardware failure of the internal occupant detection sensor mat. Because the initial WUM-98 recall was previously marked as "closed" in Subaru's automated system, the manufacturer refused to cover the repair under the recall. I was forced to pay $1,258.34 out of pocket up front to order a replacement front passenger seat cushion assembly (Part #64139SG061LL) to restore basic airbag safety to the vehicle.The initial federal safety recall remedy failed to permanently correct the underlying safety hazard. The vehicle continues to exhibit the exact same life-threatening defect (disabled passenger airbag) targeted by the original recall, and the manufacturer is shifting the financial burden of this failed remedy onto the consumer.

I am filing a formal complaint against Subaru of America for refusing to remedy an active federal safety recall (NHTSA Campaign 19V701000 / Subaru Recall WUM98). My passenger airbag is currently disabled (DTC B1760). SRS light goes on and off and visit to the Sheehy Fredericksburg Subaru location confirmed that the occupant detection system is failing and I need a cushion assembly replacement. Subaru Customer Advocacy Department claims they already performed the initial wire harness replacement for this recall back in March 2020, but unable to provide me with the invoice or documentation of where this repair was done, and they are using this as their sole justification to refuse proceeding with Step 6 on Page 8 of the official recall bulletin—which explicitly mandates the replacement of the complete seat cushion assembly if the condition persists. When I referenced federal law (49 U.S.C. § 30120(g)(1)) regarding the 15-year statutory limit for free recall remedies, the representative denied coverage claiming 'it has been 6 years.' Subaru is actively denying a mandated safety remedy, ignoring its own technical guidelines, and endangering passenger safety.

I had a recall for my ODS sensor which controls the passenger airbag. I went and had it "taken care" of due to a recall. They did not fix it. My passenger airbag will still randomly shut off while I am driving down the road. I tried talking tk the dealership and they only say "we fixed the part we needed to replace". This is a huge safety issue. If I were tk wreck and my passenger airbag was turned off, someone would die.
