A few months ago, I left the MME (2021 GT) charging at 220V for a few hours. When I went to turn it on and see current status, I got the red screen of death..pull over now! Something had happened that not only made the car undriveable, but the 12V system was affected in a way that the 12V battery would discharge while trying to power up to do anything (in particular getting the car into tow mode.) It took several attempts (with external chargers...luckily I didn't connect it to another vehicle or I think it would have died as well) to finally get the car into neutral for towing on a flat bed and I had to send the first tow driver away because he had no concept of how to tow the car. The second tow driver that showed up was great, and also knew how to use a special rig to "snag" the car from somewhere on the rails (forgive me, I forget exactly what he did) to get the car on the truck.
At the dealership, the source of the problem was that rodents had chewed through two 12-V wires on (again, forgive my terminology) one of the connections on the the high voltage control module.
Not to mention that it takes quite a bit of time to discharge the high voltage battery to work on the system, fix the connector, re-charge the high voltage and then reinstall all the software updates, this seems like a colossal design flaw. To me, designers MUST know about exposed wires. I was told the wires were "behind an inspection plate." To me, the inspection plate creates a perfect platform for any wandering rodents to find the wires at eye level. I had a 2003 Honda Civic that I parked in the same area for almost 20 years and never had ANY rodent damage. I know there are different opinions about "palatability" of wire insulation, but I hope Ford fixes this. I don't think I ever want to take the car camping or anywhere else that there's wildlife for fear that it's this easy to completely disable the car.
