* If the co-signer is the parent or legal guardian of the primary driver and the primary driver is a minor, the co-signer may be able to take the car away if they believe it is necessary for the child's safety or well-being.
* If the primary driver defaults on the loan, the co-signer may be held responsible for the debt and may be able to take possession of the car in order to satisfy the debt.
* If the co-signer and the primary driver have a written agreement that gives the co-signer the right to take possession of the car under certain circumstances, the co-signer may be able to enforce that agreement.
In most cases, a co-signer is only responsible for paying the debt if the primary borrower fails to do so. They do not typically have any rights or ownership over the vehicle, so they cannot take it away from the primary driver unless one of the above exceptions applies.
