If did change notification settings they the OP got the first response in an email and that was about it..... that is if this wasn't someone that created a second account just so that they could post this questionable topic.
Overall, I'd have to agree with most of what's been said though. Contact the lender, they really don't want to deal with repo'ing something any more than you want it repo'd. The only time this is not going to be the case is when they can potentially sell it for more than what you owe, like a house.
Yes, you could end up paying the difference.
A little story. When I was young I bought a car, then I lost my job and could not pay for said car. I told the bank to come and get the car, which they did. They sold it for 1/4 of what I owed and they filed a "judgement" on my credit and turned over the difference to a collection agency that hounded me for years. This "judgement" made my credit rating crap for a long time. These types of things will be removed from your credit after time, usually 7 years, or at least that was the case back then. When I was back on my feet I slowly paid off the collection agency, however, and here's the kicker, every time I made them a payment it extended the time that the judgment appeared on my credit to 7 years from the date of that payment. In the long run I would have been better off to tell the collection agency to go pound salt and they would never get their money, but I was raised better and believe in always paying my debts.
It's been 30+ years and things may have changed since then.
Before I gave up the car I had actually worked out a deal with the bank to just pay the interest and it was not affecting my credit at all. While I would have ended up paying much more than the original loan this way it would have cost me far less in the long run than it eventually cost me. Not only the money but the fact that I was unable to get any credit for a very, very long time.
Ahh, remembering the stupid things you did when you were young.
