EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH
Subaru of America, Inc. (Subaru) is recalling certain 2014-2016 Forester, 2008-2016 Impreza sedans, 2012-2016 Impreza station wagons, 2008-2014 WRX sedans (including STI), and 2013-2017 Crosstrek vehicles. Exposure to certain contaminants may cause the brake light switch to malfunction, preventing the brake lights from illuminating and also preventing keyless ignition vehicles from starting and CVT/automatic transmissions from being able to be shifted out of Park.
AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE
Subaru of America, Inc. (Subaru) is recalling certain 2009-2013 Forester, 2003-2006 Baja, 2004-2011 Impreza, 2004-2014 WRX (including STI), 2003-2014 Legacy and Outback, and 2006 Saab 9-2X vehicles originally sold, or ever registered, in the states of Arizona, Arkansas, Delaware, District of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia or "Zone B." These vehicles had their passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.

ELECTRICAL SYSTEM:IGNITION:SWITCH
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.

Repairs typically run $0-$500. Severity: high.
Impreza WRX models from roughly 2003 through 2014 were built with Takata phase-stabilized ammonium nitrate airbag inflators (driver and/or passenger side, depending on year and expansion phase). After years of humidity and temperature cycling the propellant degrades and the infla… Repairs typically run $0-$0. Severity: high.
Rust-belt GD-chassis WRX models are known for corrosion of the steel fuel filler neck and vent tubes behind the left rear wheel area. As the neck rusts through, owners notice a raw fuel smell, difficulty filling the tank, or EVAP leak codes from the compromised venting system. Su… Repairs typically run $300-$900. Severity: medium.
A common WRX complaint is a groaning or whining power steering system, especially when cold, often traced to the pump inlet O-ring or suction hose allowing air into the system. Aerated fluid becomes foamy in the reservoir and steering assist can feel inconsistent or heavy at low… Repairs typically run $50-$700. Severity: medium.
Many 2002-2014 WRX owners report coolant leaks from the crimped plastic end tanks of the factory radiator, especially as the car ages and sees repeated heat cycles.
