I'm not sure you understand how the Lemon Law works...it's basically only for when you buy a car that doesn't operate. No matter what problems you have with the car, unless it's caused near-death experiences and fails to start on a regular basis (and the dealer *refuses* to attempt to fix it), you don't have a case.
Just letting you know...since the dealership is still attempting to help you, you can't "lemon law" the car. Not how it works. I hate to say it...but these are the things a warranty is for. There's bound to be a car or two out of every few thousand that doesn't operate up to the bar the rest do. You got unlucky, but at least Ford is continuing to try and help.
