My 2012 SRT wanders back and forth at speeds over 65 - 70 MPH. I am constantly feeling the car sway back and forth slightly when on a straight highway with no movement on the steering wheel. I stopped at the Dealer today and the Tech. there said we don't ever see problems like that here. I lost confidence in them at that point. I did ask if it could be tire pressure, caster, camber, or tire pressure and they didn't respond. I politely said thanks and left. Again I have to be going 70 or above. My guess would be the toe adjustment.
