Engine
WITHOUT THESE FUNCTIONS ENABLED, A PERSISTENT ECM FAILURE COULD RESULT IN A THROTTLE OPENING GREATER THAN COMMANDED BY THE DRIVER AND A CRASH COULD OCCUR.
A software error exists that may allow the throttle to open greater than desired. Dealers will reprogram the engine control module free of charge to resolve the concern.
General Motors notified owners of affected vehicles starting in January 2006. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them. The General Motors recall number is 06502.
