Ford not covering factory warranty. 2011 ford escape?

I purchased a used vehicle from a dealership (not ford dealership) I had it for a couple months and noticed one day that under the hood and inside the liftgate there's rust. The liftgate is pretty bad and I would estimate a couple years before the entire bottom couple inches will be rusted off. I bring to ford dealership. And they Take pics and send to ford. As I guessed ford said it's not "perforated" which they define as a hole.

I have read the warranty and the word that they use is perforation. Now when looking up the definition of this I feel I can win a court of law. Perforation has no definition of size and also having eaten through layers is within defenition. I guarantee there are holes at the smallest levels unable to be seen by the eye and also the layers of the liftgate have been eaten through as well. What's really comical is the vehicle is a escape 2011 which is 6 years unlimited miles. It's only been shy of 3 years and it will still be covered when the rust destroys the entire gate at 3 times the cost at that time. I'd be saving ford money lol

My real question is does anyone have any advice or experience getting resolution?

I have no problem getting an attorney I have used in the past to call them for me. But I'd rather not spend a few hundred for a phone call or a letter. And yes it's under factory warranty still

You'll lose in court. In order for it be considered a defect. The rust must go all the way through the metal. Virtually ever manufacturer uses the term "perforation" and have been doing so for decades now. If you use some deductive reasoning here, you can come to the reasonable conclusion, that since they have been using the term for so long without changing it, that it probably holds up in court as you're probably not the first person have a premature rust problem, and you're probably not the first person consider a lawsuit either. Now if they were losing lawsuits right and left over this, they would've changed the terms they use years ago, but they haven't. What does that tell you about the likelihood of your proposed law suit being successful?

Also you have to take into consider the definition of "perforation"
per-fo-ra-tion

I'm kinda interested to hear why you think you can win
