I think you mean hold them liable; suing is just filing the lawsuit, and there's virtually no scrutiny. I could sue you because I don't like your username, but nobody would hold you liable for it. To the point, that lawsuit would fail for the same reason as my hypothetical username one. You lack a cause of action. Ford has not committed a tort, therefore there is no harm to trace back to BoA. You would have to demonstrate that Ford committed some kind of tort (intentionally designing a car to hit kids, or maybe being recklessly negligent in the design), and that BoA was aware of that tort (not that they could find out if they wanted, but that they actually knew). I find the opposite crazy; that you can knowingly help someone commit a tort and get off free. Is a junkyard supposed to be able to buy catalytic converters knowing they were stolen? Is a fence supposed to be able to buy jewelry they know is stolen?
