The car steering wheel and car shake violently every 2 to 3 thousand miles, at which time the service department at the Infiniti dealership replaces the brakes and resurfaces/replaces the rotors. This is the second time it has happened to us and this is a major safety issue. The stopping distance of this vehicle increases two fold because of the shaking. After reading posts by other owners, I realize the problem was known as early as December 2004 when we purchase the vehicle. The dealership did not disclose any known problems with the vehicle. This vehicle is my wifes' and two children(2 year and 7 month old) primary mode of transportation. I am wondering what recourse do I have regarding this major issue which seems to have been largely ignored by the manufacturer.
