One problem related to automatic transmission has been reported for the 2007 Saturn ION. The most recently reported issues are listed below.
Power steering just all of a sudden goes out on my Saturn vehicle while in operation. A chime sounds indicating somethings wrong and the power steering indicator comes on the dash board. You loose all power steering function and its nearly impossible to operate the vehicle to maneuver at all, at high speeds, especially when turning it can be deadly as you can't control the wheel and almost break your arm trying and can either hit someone or something. When you read over the user manual it tells you that the vehicle needs to be serviced and refers you to a Saturn location to have the repair completed. Upon visiting the dealership, they can only offer you a costly repair to replace the motor which they can't guarantee that it will ever go out again. This is not safe at all!.
