The official notice
Defect
On certain vehicles, an electrical component in the sensors for the occupant detection system (ODS) may not have been manufactured properly and could crack. Over time, moisture could enter the crack and cause a short circuit. If this happens, the passenger-front airbag may not deploy in a crash, even when a passenger is seated. Note: This problem would cause the SRS warning light to turn on in the instrument panel and the passenger airbag indicator light would display "OFF".
Safety Risk
An airbag that does not work properly could increase the risk of injury to a passenger in a crash.
Remedy
Subaru will notify owners by mail and advise you to take your vehicle to a dealership to replace the ODS sensors in the front passenger seat. To reduce the safety risk, Subaru advises that you shouldn't use the front passenger seat if the SRS (airbag) warning light is on and the passenger airbag indicator light displays "OFF".
