I was experiencing the same things (slight vibration in steering wheel at highway speeds) . Resolved after the control arm bushings were replaced (covered under my third party extended warranty) and an alignment (also covered). I had my tires balanced about 1000 mi ago during which I was told that I have 2 slightly bent rims. All is well now. I hope that the OP figured out what was wrong.
