Shake and shimmy, more pronounce at 80 Kph. At higher speeds the vibration cycles in and out while maintaining the same speed. The vibration is present with both my summer and winter tires installed. Fades in and out at all speeds.

This problem has been present since day one. At first the dealership made an effort to solve the problem, but when it became apparent it was not going to be an easy fix the dealership stopped trying, stating they would not get paid for the work. Everyone feels the problem, but no one can find it. I have had the vehicle in to other repair facilities all of whom acknowledge the problem, but are unable to find it without extensive and costly diagnostic work.

Update from Feb 28, 2016: The shacking has created a unique wear pattern on both front winter tires, not the back. I have had the tires balanced many times with no effect.
