If your auto loan hasn't been updated on your credit score since Oct 2006 and you have made six payments that have yet to show up does this affect your credit if all payments are made on time?

if your payments are made on time, and your lender reports to credit bureau, your credit score might decrease, because your lender didn't report your auto loan. however, once report is made by your lender, following month your credit score will jump a little.
