ISSUE
Some 2005-2006 Five Hundred, Freestyle, and Montego vehicles equipped with all wheel drive (AWD), may exhibit AM radio reception static only while the vehicle is moving.
ACTION
If the AM radio static starts (is present) as the vehicle begins to move and stops (no longer present) with vehicle stationary, order and install a redundant ground cable and new bolt. Attach the ground cable between the vehicle chassis and the AWD electric pump motor. Refer to the following Service Procedure. For static concerns on FM or when vehicle is not moving, proceed with normal diagnostics.
