What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
I KEEP RECEIVING SAFETY RECALL LETTERS ABOUT THE AIRBAG IN THIS VEHICLE. THIS VEHICLE HAS BEEN SCRAPPED SINCE JULY 2017. I COULD NO LONGER GET IT TO PASS EMISSIONS. I HAVE SINCE THEN CALLED THE NUMBER ON THE LETTERS SEVERAL TIMES TO REMOVE ME FROM THE NOTICE LIST BUT I KEEP RECEIVING THEM. I RECENTLY NOTICED THAT EVERY RECALL NOTICE HAS A DIFFERENT PHONE NUMBER ON IT AND IT APPEARS CALLS ARE GOING TO A DIFFERENT CALL CENTER EVERY TIME. I BELIEVE THAT THE US DOT AND NHTSA IS BEING RIPPED OFF BY WHOMEVER IS CONTRACTED TO SEND OUT THESE LETTERS. EVERY OPERATOR AT THE CALL CENTERS STATES THEY WILL UPDATE THEIR FILE AND REMOVE ME FROM THE LIST, BUT LIKE CLOCKWORK I STILL RECEIVE THE NOTICES.
TL* THE CONTACT OWNS A 2004 SUBARU LEGACY. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 20V000000 (AIR BAGS) HOWEVER, THE PART FOR THE RECALL REPAIR WAS UNAVAILABLE. THE CONTACT STATED THE MANUFACTURER HAD EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE CONTACT CONTACTED THE DEALER (WEBSTER GROVES SUBARU LOCATED AT 7982 BIG BEND BLVD, WEBSTER GROVES, MO 63119 PHONE NUMBER: 314-968-5167) WHO WERE UNABLE TO VERIFY WHEN AND IF THEY WOULD BE RECEIVING THE PARTS FOR THE REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE AND WAS NOT ABLE TO PROVIDE AN ESTIMATED TIME FRAME FOR THE REMEDY. PARTS DISTRIBUTION DISCONNECT.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
AT 26,469 miles the harmonic balancer separated into two pieces while driving causing sudden loss of power steering. I contacted Subaru for assistance with this know problem. They refused a free repair. I have been a Master ASE mechanic for over 25 years at a dealership and know repairs of this type are usually done in house under a goodwill policy, otherwise swept under the rug so there is no recall. I went to the local dealer here and the tech there said he use to do the repair almost everyday. the same thing happened to my housemates at some time and he doesn't remember the details. This is a serious problem and there should be a recall as it could result in death given the circumstances the driver is driving in.
TAKATA INFLATORS;THE AIR BAG WARNING LIGHT HAS BEEN FLASHING ON &OFF &NOW IT'S ON ALL THE TIME , THE BAG WAS SUPPOSED TO HAVE BEEN CHANGED BY THE DEALERSHIP ON JAN. 19 2017 @ NORTHPARK SUBARU HERE IN SAN ANTONIO TX.,HOW CAN I VERIFY THAT THE BAG WAS INDEED REPLACED & WHY DID THE AIRBAG LIGHT STARTED TO FLASH AFTER THE BAG WAS REPLACED A SHORT TIME AFTERWARDS , NOT ALL THE TIME , BUT EVERY NOW & THEN & NOW IT'S ON ALL THE TIME ?

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
A smell of gas was present in the passenger area. I took it to my mechanic. He said the Damper Fuel Assembly (Part # 42086AE040) was leaking. It is a high pressure gas hose. Subaru no longer makes the part, making the car valueless. We tried junkyards, etc, but that part seems to be leaking on all. It is dangerous. I can drive it, perhaps, but the gas smell is in the body of the car. Subaru said it's "unfortunate" that the car that was worth $6-7,000 last week is worth nothing. Unless I want to drive it unsafely.
