FYI I had a my car at Ford for 3 Weeks for a faulty PCM, the car was towed in due to no start. I was unable to remove Tune, Ford Motor questioned if car was Tuned, dealership who knew told Ford Motor "No"...... The dealership replaced PCM under warranty, they are awesome!!!! If you work with a Mod friendly dealership, I believe it makes a Big difference....... Has anyone had or heard of a complete failure like this???
