As the title states, my teg just started doing this tonight. I noticed it really doesn't shake until about 30 or so, but it's really bad. I know I need to do a brake job because the car shakes when I am coming to a stop but the whole shaking while cruising/accelerating thing is something new. Had the wheels balanced and rotated like 3,000 miles ago so I don't think that's it. Could it just be a case of warped rotors or what?
