The power steering on my 2005 Ion went out. The dealer wants $900 to replace the steering column. I heard Saturn has come out with a fix that doesn't require the entire column be replaced and is much cheaper. Anyone heard about this?

CHEVY COBALT ELECTRIC POWER STEERING MODES
The General Motors EPS system has several modes of operation:
* Normal mode -- Left and right assist is provided in response to inputs and vehicle speed.
* Return mode -- Used to assist steering return after completing a turn. Feedback from the steering position sensor prevents the EPS system from "overshooting" the center position.
* Damper control mode -- Used to improve road feel and dampen kickback. This mode typically kicks in at higher vehicle speeds.
* Protection mode -- Protects electrical components from thermal damage and excessive current flow if the steering is held all the way to one side in the lock position too long.

I have an e-manual that explains 2005 Ion power steering control logic. I'll post that in the next few days.

Is it right to call it a pump? I think on all Ion's it's an electric motor attached to the steering shaft.
