Overheating of the igbt occurs most often at engine start-up, but it may also occur while the engine is running. Engine stalling may occur, which could result in a crash.
Certain passenger vehicles equipped with B308 6-cylinder gasoline engines may experience overheating and burnout of the isolated gated bipolar transistor (igbt) within the ignition discharge module (idm) due to increased susceptibility to electrical loads.
Dealers will inspect to see what version idm is in the vehicle and replace the idm if it is a version built prior to January 2003. The recall is expected to begin during December 2005. Owners may contact Saab at 1-800-955-9007. Note: This recall is an expansion of a previous campaign (please see 05V399).
