Not even a full tank of gas through the replacement motor and the sound is already back. This is after this entire process of fighting Ford for over 3 months to get a resolution and giving them a chance to attempt to repair the problem and following their own engineer's recommendations in person of how he's been trying to fix these.
No Ford, you can keep your "No cost to me 5 year 75,000 mile extended warranty" and tell me which dealership I'm dropping this piece of crap off to. Upsetting that I had to get a lemon, even more upsetting how much of a joke this whole process has been. Make it right Ford, buy this thing back, and please put me out of my misery. I cannot take any more.
