YES. Get a new shop.Seems that the ability of Ford dealer technicians and/or FoMoCo to diagnois the fix of many EV problems is lacking. I sure hope this improves soon or it will have a negative impact on future EV sales.
I had 9 months of BlueCruise nightmares until a Field Service Engineer from Dearborn came out with a laptop and a special cord to fix the untold horrors wrought upon my Mustang by an unqualified dealership, who kept insisting that "What? It's fine! It's supposed to not work properly and you're a fool!"
Ford sent the right person, who was obviously a ninja, and they fixed it in a couple hours, including the test drive and wash. Ford has the right people, they know how to fix ALL these problems.
