Can a dealer after voluntarily returning a car over 3 years ago now come after you for the remaining balance?

In a Word yes.Just because you voluntary returned the car doesn't mean anything to the lender they still want the balance of their loan.You need to find a few things out to help yourself.First find out what the dealer did with the car did he auction it or resell it?Most importantly how much did they get for your former car?The difference between your original loan amount(including all the interest)less your total payments and less what the dealer got for your former car should equal the remaining balance BUT CHECK The NUMBERS !!!!!!!!!!!!!!!!!!! IT is a good idea to conduct all correspondence with the lender/collector in writing only and read what they you send very carefully!!!!!!!!!!!!!!! GOOD LUCK
