SOS, this issues is covered for 150K miles on the 2010 (Bulletin 13N02) but knowing Ford, there will be a dog and pony show at the dealer about it on my 09. Same equipment and system as covered in the 2010.... Problem Description and Possible Solution Bulletin 13N02 - This program extends the coverage of the brake booster to ten years of service or 150,000 miles from the warranty start of the vehicle, whichever occurs first. This is a one time repair program. In some of the affected vehicles, it is possible for the brake booster to develop a small tear in the diaphragm under certain driving and environmental conditions. If this occurs, the driver may hear a hissing noise while depressing the pedal and may also experience a "spongy" pedal feel without a noticeable effect on braking performance. If the vehicle is not serviced, the tear will eventually expand and the pedal effort required to stop the vehicle will gradually increase. However, in all cases, the fundamental vehicle braking system remains functional.

Update from Oct 4, 2016: Yep, as guessed, Ford refused to repair the problem under warranty, it is the exact same item, exact same part and exact same manufacture of the part as the one that has been recalled for 2010 and up.... No more FORDS!
