However, it's important to note that there may be some exceptions to this rule depending on the specific terms of your loan agreement or state laws. For example, some states allow for "cross-collateralization" which means that if you have multiple loans with a lender, the lender can repossess any of the vehicles securing those loans if you default on any one of the loans.
To be sure, you should review the terms of your loan agreement carefully or consult with an attorney to understand your rights and protections.
