No, you cannot go to jail for a repossessed car in Wisconsin. However, you may be held in contempt of court if you violate a court order that requires you to surrender your car.
If your car is repossessed, you may be able to get it back by paying the past-due payments, plus any fees and expenses incurred by the lender. You may also be able to get your car back by filing for bankruptcy. You should also make sure the lender followed the right steps in the repossession, and that your rights were not violated.
If you have any questions about your rights after your car is repossessed, you should contact an attorney.
