Pretty sure you got a lemon, at least with some of the electronic components. You should consider filing a buyback request or starting a lemon law filing. You've got some bum parts in there, and I think it's hardware, not software. I see you're trying a mongoose and to manually patch some things up. Good luck. Also, you might just try finding a better dealer service center. Kind of sounds like the one you were at was pretty apathetic about your situation.
That adapter will allow you to charge at Level 2 Destination chargers (10 hour or overnight charging).
Do not buy it. @Ford Motor Company does not value customers. If you are lucky, and do not have to deal with a a bad dealership that hates EVs, then you may enjoy the product. If you are part of the unlucky ones that need a battery replacement etc, then be ready for one of the worst experiences in your life.
It does suck that our experiences are so tied in to dealers. Sales guys don't really matter, they may just try to steer you to a vehicle with a higher margin. But when the service department is untrained, and doesn't believe that EVs are worth it, you'll never get decent service from them. It's why several local groups have discussed where the good and bad dealers are. OP needs to research which dealers in their area have had good service department experiences with EVs. and go there. Also good to know which ones to avoid.
