2013 Subaru Outback steering problems

2013 subaru outback 3.6r w/sap I am experiencing a heavy steering issue. Where the return to center does not happen unless I manually steer it back to center. Steering is so heavy that after 3000 miles. (purchased in june 2013), both of my wrists are in pain, my right elbow is in pain, and my right hand feels like it has carpal tunnel syndrome. Constant corrections are needed to keep tracking straight. I increased tire psi to 34/32, and it helped a little, but steering still does not return to center.

The vehicle does not track well at highway speeds. It wanders side to side in the lane of travel requiring constant correction to stay in the center of the lane. On smooth road surfaces, the wandering is relatively mild. However, I became alarmed while crossing a bridge with a grated deck. The vehicle swerved side to side dramatically requiring significant steering correction and immediate reduction in speed to maintain the lane of travel safely. I took the car to the dealer and reported the problem.
