I am normally the last to say this, but lawyer up, if you have all of the paper work, lawyer up.If you need a name that handles these types of cases, let me know. They wont charge unless they win, and they have already taken care of another friend who had MANY issues with his 6.0, the final was though the dealership left something loose in the motor, it punched out a cylinder. Took 8 months but he was able to walk away from the truck with out owing anything.

Good Luck!!
