It sounds like alot of us have had bad experiences with Warranty work. In all honesty, since I found my current dealership, I have had nothing bad to say. They have covered many, many claims. I have had a Very problematic past. One I had them look at a faulty MAF sensor while I still had the KKM/Vortech 73MM MAF on the car. They told me what the problem was, I went home and swapped back to the stock airbox and when I returned it, they replaced the part... All for the $50 deductable that the Platinum Warranty calls for. No hassles really. I will buy a Ford again (but only from Pioneer Ford) because I want to keep the relationship with my Service Advisor.
