Normally, if the loan is in your name, you are responsible. If you worked something out with the dealer, they should be responsible. You might want to look in all the paperwork from the dealer to see if it is in writing somewhere that they would pay off the loan. Either way, it wouldn't hurt to call the dealer. I would also call the bank, or where ever you got the loan from, and let them know what is going on.
