If your loan is current and you turn the vehicle back in to the lender can it still be reported as a repo?

YES! A repo is a repo. If you turn the vehicle in to the lender and stop making payments this is called a voluntary repossession. The lender will sell the car and you will be responsible for the difference in what the car sells for and the balance on the loan. It will be reported to all 3 credit bureaus as a default on a loan, and your credit will be ruined for 7 years. You would however save to repo fees such as towing. Do not do this. Call the lender and work something out if possible.
