The owner of the vehicle is not criminally liable unless that person knowingly let a suspended driver operate their vehicle. However, the owner should call the impound lot and pay any fees to recover the vehicle. If the owner is unable to pay, there is a risk that the car will be sold at an auction to pay the fees.
There is a procedure for the owner to petition the court and it can be released to them. They can do it by themselves but I recommend getting an attorney to make sure that it happen sooner rather than later.
