no, my 08 runs and drives real nice. Are they putting on the wheels correctly? or are they just impacting the rim at full force 150psi on 1 lug nut causing the whell to be on crooked. The owners manual states "dont not use an impact wrench" on the rims. Putting on the wheels wrong can cause a imbalance or a shimmy at speeds. I hope this helps. Tell the dealer to put on a different set of tire/rims. The driveshaft is balanced, you'll see weights on it. Also did the roadforce balanced the tires for you?
