My x developed a new problem. New front rotors installed by the dealer, take it out on the road and it vibrates while braking only. After a week I bring it back and the dealer replaces the rotors again and tells me that the right side rotor got eaten up much more than the left one after only one week. They replace the rotors again and the problem with shaking and warping the right side exists. Any ideas?
