Electrical recalls for the 2012 Subaru Legacy

Electrical system: switch

19V297000511 vehicles affected

The problem
Subaru of America, Inc. (Subaru) is recalling certain 2009-2013 Forester vehicles, 2008-2011 Impreza vehicles, 2008-2014 WRX vehicles, 2005-2014 Legacy vehicles, 2005-2014 Outback vehicles and 2006-2008 Tribeca vehicles equipped with a mechanical key ignition switch installed as a replacement part. The ball spring inside the switch may break, reducing the strength of the ignition switch. If this occurs, the weight on the key ring and certain road conditions could cause the ignition switch to move out of the run position to the accessory position, turning off the engine.
The risk
The engine turning off unexpectedly can increase the risk of a crash. If a crash occurs under this condition, the air bag may not deploy, increasing the risk of injury.
The fix
Subaru will notify owners, and dealers will inspect the ignition switch, replacing the ignition switch, if necessary, free of charge. The recall began May 10, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUF-91.

Electrical system

13V06100047,419 vehicles affected

The problem
Subaru is recalling certain model year 2010-2012 Legacy and Outback vehicles equipped with an automatic or CVT transmission and an Audiovox remote engine starter (RES) accessory, certain model year 2012-2013 Impreza vehicles equipped with a CVT transmission and an Audiovox remote engine starter (RES) accessory, and certain model year 2013 XV Crosstrek vehicles equipped with a CVT transmission and an Audiovox remote engine starter (RES) accessory. Additionally included are certain model year 2013 Legacy and Outback vehicles that may have received replacement RES fobs. If the RES fob is dropped, the fob may malfunction and randomly transmit an engine start request without pressing the button.
The risk
The engine may inadvertently start and run for up to fifteen minutes. The engine may continue to start and stop until the fob battery is depleted, or until the vehicle runs out of fuel. If the vehicle is parked in an enclosed area, there is a risk of carbon monoxide build-up which may cause headaches, dizziness or, in extreme cases, unconsciousness and/or asphyxiation.
The fix
Subaru will notify owners, and dealers will replace the RES key fobs, free of charge. The recall began on April 22, 2013. Owners may contact Subaru at 1-800-782-2783 for more information.

Engine stalls after abrupt stop. For example, I was on post road in westport connecticut and slowed down from 25mph+ very quickly with a hard brake.

This problem is consistently reproducible and has happened 10+ times. Subaru has acknowledged the issue...

I brought the car to hank may's in norwalk, but they were unable to find a cause for the issue. I have reached out to subaru concurrently with this report. They will be examining my car to determine what the issue is and whether it will be covered.
