If you are 45 days behind on your car payments and have moved and not given the lender your new address can they come after you and can you be jailed for hiding the car?

If the lender wants the car back and doesn't think you are going to pay because you have moved, they can find you in much less than 30 days. Look at it from the lender's viewpoint: you're 45 days late, moved, left NO forwarding address, no way to contact you. WHAT does that look like to you?

And, YES, in some states it IS illegal to hide secured collateral.
