SOMETIMES WHEN I RESTART THE SUV AFTER ABOUT 5 MINUTES IT WILL COME BACK ON AND IT STAYS ON UNTIL I SHUT OFF THE SUV. THEN NOTHING FOR WEEKS. I'VE WANTED TO TAKE IT TO THE DEALER BUT EVERY TIME I START TO HEAD OVER TO THEN THE FAULT GOES OUT OR NEVER COMES ON? I'M SURE IF I JUST HEAD OVER I'M JUST WASTING MY TIME. THE LAST TWO MONTHS IT'S BEEN MUCH MORE ACTIVE WITH THE FAULT HAPPENING. I'M LISTING THE LAST TIME IT HAS HAPPEN AS 01/10/2020. I KEEP NOTHING ON THE PASSENGERS SEAT AND I AM UNSURE IF THE AIR BAG LIGHT (YELLOW LIGHT ON THE DASH) SHOWS THAT IT IS ON OR OFF WHEN IT COMES ON. MY WIFE WAS DRIVING ABOUT A WEEK AGO AND I WAS IN THE PASSENGER SEAT (6' 225 LBS) AND THE SRS FAULT COME ON AND THE YELLOW AIRBAG LIGHT SHOWED IT WAS STILL ON. I HAVE A TRIP TO PITTSBURGH PA FROM ALLENTOWN PA AND I'M WORRIED THAT IF I'M IN AN ACCIDENT THEY WON'T GO OFF AND PROTECT US. THIS CAR IS JUST OUT OF WARRANTED AND I HAVE ABOUT 44K ON THE VEHICLE.

Official recalls
319V701000 · 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.
19V149000 · Exterior Lighting:brake Lights:switch
Feb 28, 2019
Subaru of America, Inc. (Subaru) is recalling certain 2014-2016 Forester, 2008-2016 Impreza sedans, 2012-2016 Impreza station wagons, 2008-2014 WRX sedans (including STI), and 2013-2017 Crosstrek vehicles. Exposure to certain contaminants may cause the brake light switch to malfunction, preventing the brake lights from illuminating and also preventing keyless ignition vehicles from starting and CVT/automatic transmissions from being able to be shifted out of Park.
Consequence & remedy
Consequence: Brake lights that do not illuminate properly will not alert other drivers that the vehicle is slowing or stopping, increasing the risk of crash.
Remedy: Subaru will notify owners, and dealers will replace the brake light switch, free of charge. The recall began April 15, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUE-90.
16V162000 · Engine And Engine Cooling:engine:gasoline:turbo/supercharger

1PE19009 · 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.
