Recently me and my wife just purchased a brand new 2013 Impala with 29 miles. The steering wheel shakes from left to right going down the freeway about 60 plus. I have had the balance rotated and balanced three times twice by the dealership. The problem is still there. then we were told by the shop foreman that that's just the characteristics of the vehicle. Bull s***. So now I'm stuck with this god damn vehicle and don't know what to do about it. This is my very first brand new car for me and my wife. Very unhappy campers. When going for a test drive with the foreman he tells me that it's the rubber base asphalt. Again b*******. I told him I don't give a f*** if its plastic glass or whatevere that were driving on it still should not have a shimmy or a vibration in steering well that goes from left to right. Then he tells me yeah he can feel the vibration but he doesn't know how to fix it. So is there anybody in here they can give me some advice on what I should do. Thank you very much.
