You can give the car to the bank in a voluntary repossession. It is handled the same as a repossession, so if you owe more than what they sell it for (usually at auction), you can be responsible for the difference still. This will be reported on your credit history and can lower your credit score. But, if you cooperate, they might be willing to not report it (up to the bank). I did a voluntary repo, and they agreed to not report it if I paid the balance within a certain period of time (which I got in writing form them, and came in handy when I found it on my credit report. Disputed it, sent a copy of the letter, and it was removed.)

If the value of the car is worth more than the loan, you could look at selling the car, and taking the money to pay off the loan, keeping what ever is left over. If you can, this would be the preferred way. It keeps your credit report as it is now (assuming you continue to make payments while selling it), and you might even come out with some cash after you pay off the loan.

you can voluntarily return the vehicle to the finance company BUT you will still be responsible for the loan balance after they auction off the car

sell the car and pay off the balance. problem is you probably owe more than it's worth

No, you cannot. Even if you sell the car, you will owe the remainder.
