I bought my 99 3.0 a month ago, and had to take it back to the dealership a week later because it would shimmy when I turned both ways, when I braked, and when I'd accelerate slow/decelerate slow. (around 1600 rpm) I had assumed that it was the brake rotors, because my Jeep cherokee was doing the same thing, and I had to have them turned. Anyway, sure enough, they said my cl's rotors were worn so they turned them at no charge because of the manufacturers warranty. 2 days after I picked it up it started doing it again! Have you ever heard of that! Do you think it could be something else? If I take it back in, I'm telling them I want brand new rotors if they are covered under warranty!

 

I would take it back to them and tell them that you want new rotors and an alignment.

 

I believe that this means that the rotors are warped, maybe by turning it is still the same. Just tell them you want NEW rotors. Or you could always spring for the good ones and get aem crossdrilled/slotted rotors.
