I have had my tires re-balanced at least 6 time, realigned 4 times, both the rear wheels replaced and all 4 Hankook's replaced with Continentals. The car still pulls to the left and shakes like crazy. Now they tell me all 4 rims are damaged and are being replaced. Seems more like a manufacturing problem with the rims or suspension more than anything else. Guess we'll see when I get the car back again.
