The Ford dealership that he sold his vehicle to cannot reasonably claim innocence, and has put this man's, and his family's, life in danger.
Now, whether if the Ford dealership is legally liable, I don't know. However, they're basically screwed: they'll forever be remembered as the dealership that sold a vehicle to terrorists (no matter if that is technically true or not; they immediately unloaded it at a car auction like all dealerships do if they don't have a local buyer already lined up).
I'd like to see an investigation, however, why a perfectly working truck was shipped overseas and left the American market. I know working computers are "recycled" (ie, dumped in a hole in the ground somewhere in China, India, or Africa), but I wasn't aware we did the same to vehicles.
