So they did align it the last time I was in when they replaced the one tire. It was just slightly out. So that didn't fix it either. I looked at the weights on the tires (which are the Bridgestone Turanza by the way) and there is more than 28g of weight on each of the front tires and close to that same amount on one of the back tires. The other back tire which I think is the one they changed out most recently, has no weight on it. So, I guess you can have a perfectly balanced tire, but I find that odd. Anyway I called and asked, they said it was balanced and there was nothing else they could do "it is a characteristic of the car". I am extremely disappointed. I picked this car after many test drives and research and did not experience this vibration during the test drive (the car I test drove is the one I purchased). In fact I purchased the car because it was such a smooth quiet ride. I would love to keep the car, just minus the vibration. However, if they cannot fix it, I definitely don't want to live with it like it is. I absolutely dread driving it right now! I'll keep ya posted.
