The shifter cable adjustment may become dislodged. This may cause the vehicle to show that it is in "Park," when it could actually be in another gear. If this happens, the vehicle may move and not be secure. Dealers will inspect the shift cable adjustment clip to make sure it is fully engaged, and will replace any shift cables that cannot be secured. The General Motors recall number is 09041. The recall began on March 24, 2009.
