1. Confirm the borrower's information: First, you need to confirm the borrower's information, including name, ID number and contact information, so that the other party can repay the loan on time.

2. Negotiate with the borrower: You need to negotiate with the borrower to understand its repayment plan and ensure its repayment on time. If the other party can't repay the loan on time, you need to communicate with it and try to solve it.

3. Transfer the ownership of the vehicle: If you have sold the vehicle to others, then you need to transfer the ownership of the vehicle to the buyer. You can go through the formalities of vehicle transfer by submitting relevant formalities to the local vehicle management office.

4. Pay off the loan: If the borrower cannot repay the loan on time, you need to contact the bank as soon as possible to negotiate the repayment plan and pay off the loan as soon as possible. Otherwise, your credit history will be affected, and even your future credit loans will be affected.

In short, if the vehicle has been sold, but the car loan is still in your name, you need to communicate with the borrower in time to ensure that the rights and interests of both parties are guaranteed. At the same time, it is necessary to handle the vehicle transfer procedures in time and transfer the ownership of the vehicle to the buyer to avoid unnecessary trouble.
