 I was excited to get my brand new F150, with the 3.5 twin turbo and ten speed tranny. That said, I took my new truck home and within a week noticed significant rust on several drivetrain components and on the rear differential. I went to the dealer and asked how a brand new car can have embedded rust already on it. They said not to worry, that it's normal on all their new trucks. They referenced the rust that you see on brake pads when a vehicle sits for a long period of time, this comparison is total crap. The next time you use your brakes the rust will disappear, while the rust everywhere else simply gets much worse over time. I did not realize until later the document they had me sign regarding future rust issues. I was told by a knowledgeable person that Ford decided to lower their use of environmentally unfriendly paint, which has dramatically reduced rust protection on the metal frame and other underbody components. Two months in and there are now new spots of rust, I should not have to deal with this on a new expensive truck. What a shame, I'll never buy a Ford again.
