Me too. That can be caused by:
1) Your engine is 2000BHP crank and the force with which it thrust your car forward squatted your *** end so hard the panhard bar reached buckling point
2) That was one hell of a pot hole your rear wheel hit
3) Factory defect: Go back and talk to your dealer and see if they will warranty it.

I am leaning towards number 3).
