Front Suspension Control Arm problems of the 2012 Ford Mustang

Left&right lower control arms has unseasonable amount of rust which is blistering from the inside-out, also is deep and progressing with time,which will become a safety factor,the car has only 3,300 original miles.

When traveling over large bumps in the road surface, the vehicle would emit an audible squeaking/groaning noise from the front end. It took multiple visits to the dealer in order for them to even acknowledge that the problem was even there. I was finally informed that there was a TSB for this issue and they replaced both lower control arms. On w/e March 23, 2013 this problem began to reemerge but the dealer has once again denied the existence of such noise. I have been told that I must wait for the problem to worsen before they do anything further.

While slowly driving around some pot-holes on a uneven pavement in a det. Mi. Area , I felt and heard some loud squealing from under the front of the car. Seconds later I noticed the manual gear shifts were very stiff and had use more effort to make manual shifts. Days later, I took the car to my local Ford dealer for my 5000 mi oil change and inspection. After ordering parts, I took the car back and both lower control arms and bushing were changed. I am not sure if the mechanic also worked on the gearbox or not. For about a week the gear shifts were very smooth, but they vary now , from smooth to stiff.
