I heard that this problem is common to Hondas? I have had the mechanics thrice look at the car: they've balanced the tires, air pressure if fine. When it first occured, it was in the winter and they thought it was ice. But it's the summer and the problem persists. I also heard that it might be a sign of a cracked steering column??? the steering wheel vibrates a little, but my car/wheels stay straight ahead when i take my hands off them. I'm perplexed (apparently, so are my mechanics).
