One recall on the airbags covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.

Air Bags:Sensor:Occupant Classification

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.

Risk and remedy

Risk: 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.

Airbags · model years 2016 to 2018

Occupant detection system (ods) failure. Closed jan 22, 2020, led to recall 19V-701.

NHTSA summary

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.

What owners wrote

“Airbag light comes on due to some failure in the passenger seat. This vehicle year has had a recall on the same issue but this VIN number was not included for some reason. Another consumer posted his assessment which I have attached. My vehicle falls under his category. He has sold his since his was never resolved.”

“Passenger front seat. Airbag light is on when someone is sitting in the seat and seatbelt indicator dings when nothing is in the seat.”

“My airbag warning light comes on intermittently. My mechanic found it is due to a recalled part but my vin number is not listed on the recall even though it meets the criteria. Subaru Safety Recall WUM-98 NHTSA Recall ID 19V 70. The person in the passenger seat's safety is at risk if the airbags don't deploy in the event of a crash.”

“I have had a airbag light on for the passenger side of the car for a long time. Subaru said it is from water damage. I do not recall water damage - I didn't drive through a flood. I understand there is a recall on 2015-2018 Subaru Foresters with and has heated seats but even though my car falls within those parameters my VIN shows up as not being recalled. Something seems fishy!”

Should you keep driving it?

This page can't tell you that. 0 of 36 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
