Here's the NY Lemon Law :
The New York Lemon Law applies to new cars, both purchased and leased, which suffer a nonconformity; a defect or condition, which substantially impairs the use, value or safety; that has been addressed a substantial number of times (normally 3-4) by an authorized manufacturer's dealership. This nonconformity must first occur within the first 24 months or 18,000 miles, whichever comes first. The New York Lemon Law also applies to vehicles that are in the shop for repair thirty (30) or more calendar days during the first year.
You obviously have a case. I have had two cars lemon lawed, a Dodge Durango and a Mazda CX-7. The Dodge was a quick process, two months from start of process to having a check in my hand. Mazda quickly agreed to buy my car back, but took nine months to finally pay up. Hopefully Ford will be a quick turnaround for you. Good luck.
