You have to call your loan company. If it is Ford Motor Credit, that is who you call. If you went through a bank, that is who you call.
Good luck with that. I had to store my Toyota for a year at my own cost, because Toyota Motor Credit wouldn't release mine when I went to Korea. The DoD will not pay for storage if you are authorized to ship, even if the reason you don't ship is because the bank won't give clearance.
