There is a technical service bulletin 12-192-15R that addresses this. I wrote to Subaru and asked whether my car was affected. Although there is a maximum VIN in the bulletin that indicates the cars that are affected, I don't know what it is (and the person from Subaru didn't say anything). If anyone has access to that publication, I'd be curious to see the VIN (so I can have something else to worry about, I suppose).
