“Some loans have caveats that you can only be ahead a few months on your loan; this is relatively common.
To answer your question, a payment reversal simply means they’re going to send your money back to you. You aren’t out anything; they’ll just credit your bank account for your last payment.
If you want to get ahead on your car loan, don’t just spend money on the actual loan payment. Instead, put your extra cash toward the principal. Known as a principal-only payment, this money lowers the overall amount you owe, which leads to less money spent on interest over the life of the loan.”
