I disagree, Ford is really getting tough on warranty issues. My son-in-law has an X-Plan 2011 Ford F-150 4x4 Lariat V-8. He has taken it in 3 times for a Service light regarding his Advance Trac. When you turn the vehicle off it clears and no codes are showing up when tested. I spent about 5 minutes on the internet and found that it is the steering box. This happens when you turn the wheel all the way to the left. The dealer has now been able to replicate the issue every time one turns the vehicle all the way to the left. Even though Ford has been replacing some steering boxes for this issue, which successfully solves the coding, his dealer is getting the royal run-around. Hard to say if there is a real fault in the Advance Trac operation, or if the issue is only during extremely tight left turning like when parking.
My son-in-law is so irritated with Ford's actions, that he won't be buying a new Explorer Sport this fall, to replace his Honda Pilot.
When the claim is expensive, Ford is going to look for anything related to their already published TSB's , and the dealer can't do anything about it. However, unless there is a defective part, or you push your engine beyond what you have already done, you likely won't have an expensive claim.
