Well, they can and do seize cars regularly. If you give an illegal immigrant a ride (even innocently, even if you have no idea who they are and from your perspective you're just giving a hitchhiker a ride) and Border Patrol stops you, they will steal your car. They won't charge you with a crime unless you're an actual human trafficker, but your car gets taken away.
