I am experiencing steering problems, especially at highway speeds. Feels like steering control is lost for small steering inputs and displacements. Like too much free play in the steering. I don't want to drive the car on a highway. Is this bad enough for you? I will sell this piece of junk if I have to be keel hauled by the dealer's "parts changers". I won't do that dance. I won't tolerate that. This is real, makes the car almost undriveable. NEVER experienced such with any other car.

It is real not imagined. Good chance it showed up earlier but has grown in obviousness.

Suspension inputs are also involved. With roadway bumps, the up movement (rebound) of suspension is felt in the steering as well. When wheel travel is downward it doesn't happen.

With engine running and at idle, too much play in the steering wheel.

Update from Sep 12, 2018: I suspect it was my inexperience. I accidentally pushed a steering wheel mounted switch which initiated a lane control function which I didn't know I had. I would not be inclined to ever use it. I have driven for 60 years. I would need to practice before using such a thing.

It did get my attention and frightened me.

My brand new Subaru Forester has a very serious steering problem. The wheel is jerked from you while driving down the highway at speeds between 55 and 70MPH. While passing a semi-trailer truck on the left side, the car tried to steer me under the trucks trailer. I had to fight the wheel to keep it from steering me under the trucks trailer. The car will steer right or left leaving you feeling as though you have lost control as in a hydro planning experience.

I plan to return the car to the dealer and see if they can find a fix for it. The toe alignment could be off or the electronic steering assist is not functioning as it was designed to. The vehicle currently has 500 miles on it.
