Got an update from the dealer. They have condemned the TCM. Thats what they said. Troubleshooting has found it to be bad and most likely the source of the problem. They ordered the part and will install it next week when it arrives. They seem fairly confident. Hmm, are we taking bets? Lol. On a side note my car was fully charged and driven 4.8 miles today. Strange.

It sounds like they're way ahead on yours...narrowed down to a single component! (maybe?)
My car can't be charged or driven at all, until they figure out why it's not "seeing" the HV battery.

My dealer did say Ford is sending out "some" field reps to look at it. I hope that means before end of the month.

I had wondered about that. I thought the tcm was just that box on top of the "motor", that all the orange cables plug into. But I had seen posts that suggested that it was the whole motor assembly. I had searched for images of the tcm and all I ever came up with was an underhood shot of the motor with the cover off suggesting that it was just that top part. Is it really the whole motor assembly?

Yes the TCM is that whole hunk of metal bolted together in the position that would be the engine in an ICE vehicle. It consists of the motor, gear box, inverter, and high voltage junction box. That box on top with the orange wires is the high voltage junction box. You've got the battery coming in on the driver's side and on the passenger side the HV going out to the DC-DC, heater, and AC compressor. I will throw out an uneducated guess that maybe there is a problem with the inverter. Since the inverter is a part of the TCM assembly they just replace the whole assembly as it would be impractical (cost prohibitive) to train the dealership mechanics on how to disassemble a TCM and repair an inverter.

Think of it as like an automatic transmission in an ICE car. A dealer will not disassemble a transmission to fix it. They will replace it with a new one. This is probably because modern automatic transmissions are extremely complicated and it would be impractical to keep someone with the necessary specialized training at each dealer to work on bad transmissions.

Except for the part about the whole assembly being the TCM take the rest with a grain of salt as it's just wild speculation on my part.

Thanks for that explanation. I posed that question to my dealer tech contact and he said yes, it was just the box on top but that the whole assembly would be replaced if they replaced it. That answered my question but it was the word if that struck me as odd. I had been told last week that the part was being ordered so "if" must have just been a poor choice of words on his part. I think ford is supposed to call me today so I will make sure the part has been ordered. I think monday and thursday are my contact days for ford corporate. I still dont think the dealer knows I called ford. I think they still think the ford tech guy just showed up out of the blue (no pun) to help them out. The dealer also told me that I needed to talk to the service manager about getting my payments refunded. When I told them that I had taken care of that with ford already they still insisted that I needed to go through the service dept for that. I told them that ford had already received my info to take care of that for me. They were like oh, ok.

I hope those field reps get there sooner than later. Have you called ford corporate yet? After I did that the field rep was at the dealer within 2 days, they opened up a case for me, initiated a twice a week update call schedule with me and took my paperwork to get my payments refunded once the car was fixed. It seems to have gotten something done in a week that couldnt get done in 9 weeks previously.

I haven't called corporate yet. What number did you call? And what magic words do I need to say to get connected to Darren? Sounds like he's definitely the guy to talk to.

I called the customer service number. Then I followed the prompts to get to the EV car section. Darren was just the guy I got. Im sure there are many others. Just tell them that you understand its new tech and all but its been 2 months and you feel that the dealer may need some help from a field rep. The ford ev expert needs to actually go and look at your car. Also tell them that the loaner is nice and all but youve been making payments on a car you have not seen for 2 months. They will probably assign you a case number and someone will probably email you as your rep. They will most likely ask for your statement so they can get the ball rolling on refunding payments once the car is fixed. Good luck, I hope it gets results for you.

So, my suspicions were correct about the word if. It turns out that they only requested authorization from ford to order the TCM. They are waiting for an answer. I was told that if ford says yes then they will have over $20,000 in warranty repairs into my car. The TCM is $15k alone, im told. What if ford says no? Do they buy back my car? Offer up a replacement? For 15k I could get a used 2015 or 16 with a warranty. LOL. So, basically, more waiting.
