I don't disagree. Except this was dealing with Ford HQ to resolve an extended warranty disagreement. I also had to do something similar with the first luxury car I dealt with. You see, extended warranties climb up the food chain since the manufacturers have made the decision it's cheaper to fix the problem than to ignore it (A * B < C in the famous fight club reference). They also need to authorize it.
Luxury car was a fight but they caved relatively quickly. Ford is an ongoing saga that has now taken longer to simply prove there is a problem than it took for luxury car to resolve the whole ordeal. Kia would likely be worse since they were selling Stingers at a huge markdown for awhile. I'll pass and stick to Toyota which hasn't had any major reliability problems in the past decade on their vehicles and have great service centers (in my very large metro area)
