Regarding the LCA problem, I have similar experience. I had my dealer replaced all LCAs thi summer because of the front squeaking problem. But they are back again. I am going to take my stang to dealer for the 2nd time.
I don't know how should I survive this after warranty. It costs big money. parts, labor, and wheel alignment....
Should it be considered as design defect? I think Ford should definitely take the responsibility for this. They need find real solution to this rather than keeping on replacing same problematic parts until warranty expires.
My car is a 2012 vehicle.
