I am not 100% sure what you are asking. If you are asking for the statute of limitations on a car loan in Indiana, my sources indicate it is ten years. Periodically however, state legislatures amend the statute of limitations on different types of debt so to be 100% sure that I am accurate, I advise you to call your state attorney general's office or the office of a consumer law attorney who helps consumers resolve their debt collection problems in your area for a definitive answer.
If you are asking what the statute of limitations on a repossession deficiency is in your state, I do not know the answer to that question. You will owe a deficiency if your vehicle was repossessed and sold for less than the balance due on it. The difference is referred to as a deficiency. Again, your state attorney general's office or a consumer law attorney in your area can answer your question.
One suggestion. If you owe a deficiency, the lender may be willing to let you settle the debt for less than the full amount, especially if you can pay the settlement amount in a lump sum. Settling the debt would free you from having to be worried about being sued over it sometime in the future.
