On certain passenger vehicles, an interaction between the sensing and diagnostic module and vehicle's electrical system may cause the driver's frontal air bag and/or roof-mounted side impact air bag to deploy when the ignition key is turned to the "on" position.
Dealers will replace the sensing and diagnostic module free of charge. The recall began on May 20, 2005. Owners may contact Cadillac at 1-866-982-2339.
