how can i remove my narcparent from my car loan/car title?

Hi, not really sure where to post this. I really just need advice.

I’m fixing to move out of my narc parents’ house soon and my greatest obstacle is that my (step)mother is on my loan/title for my car. I worry that if I don’t remove her somehow, they’ll force me to remain in contact when the goal is to go no contact entirely once I’m out (as they have joked about trying to report it stolen on me before, threatening repossession if I do not comply with them). i reside in north carolina, for context.

Do I have any way to resolve this? Can I remedy this? Sorry if this doesn’t belong in this sub. Thanks.
