What owners report

  • Airbags sometimes failed to deploy for several seconds after a crash, with burning fumes entering the cabin in one case.
  • Some owners reported the vehicle suddenly lurching forward at high speed while pulling into a driveway with no foot on the accelerator or brake.
  • Electrical failures included a battery warning light and heavy power steering followed by smoke filling the passenger compartment and an under-hood fire.
  • Owners described brakes failing to respond when depressed, leading to rear-end collisions.
  • At highway speeds above 60 mph, some owners reported a wobbly or swaying feeling and steering wheel shimmy that persisted despite tire balancing or replacement.
  • One owner reported dashboard warning lights illuminating in snowy conditions, later traced to the battery, starter, cable, and ECM needing replacement.

    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 (STI included), 2003-2014 Legacy and Outback, and 2005-2006 Saab 9-2X vehicles originally sold, or ever registered, in the states of Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands or "Zone A."

The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.

    Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

    Remedy: Subaru will notify their owners. General Motors will notify Saab owners. Dealers will replace the passenger air bag inflators with alternate inflators, free of charge. The recall began January 7, 2020. Subaru Owners may contact Subaru customer service at 1-844-373-6614. Saab owners may contact the Saab Customer Assistance Center at 1-800-955-9007.
