TSB's are NOT free if the car is out of warranty.
My SVT Contour had a "hooting" noise problem that developed at 20K miles or so. I didn't take it in until 40K miles and they found the TSB that covered it, and offered to perform the service for $300.00.
TSB's are not recalls. They are not safety mandated.
I think it is a load of BS that they admit that they 1/2 a$$ engineered or manufacturered something, and since they don't figure it out until your car is out of warranty, then it is your problem. Thanks Ford!
The only leg you may have to stand on is if you took it in for the problem, unresolved, before the warranty expired.
