I am sorry to say that I would have no idea as to what is causing your repeated electrical issues! However as to the dealership questions.....by all means yes..go to another dealer. Get hold of FORD and get in touch with a district manager to speed inquiries or investigations up. I had an issue with my Fusion and ultimately I sourced the problem and with help from the Forum resolved it at NO COST versus what the dealer was telling me to do! Not automotive related, but I had purchased a big ticket item from a "box" store....Had trouble with the same from the onset, did everything by the book as per warranty and certified repair facilities all to no avail. After only 3 days of using social media to MESSAGE, the manufacturer, and the retailer, the retailer decided to replace my purchase with a brand new out of the box unit, now over a year old and past warranty, at no further cost to me. My saving grace was that I had ALL documentation including my attempts to do everything required by warranty.......repair bills, email coms, "case #'s" over a 12 month period, etc etc. Good luck and keep us posted !
