I have a 2008 Ford f150 Lariat package. At about 35k miles, the driver's seat broke. The base of the seat began squeaking and became very hard. I had it replaced under warranty. It has been about a year (and more than 12k miles), and the seat is broken again. Of course, Ford refuses to replace it. Certainly two broken seats before 60k miles is an indication of a defect in the seat. I'm looking to hear from other owners who are suffering a similar problem.
