As you may all know, there is a way to do loan modifications for homes. It has to be caused by a financial hardship. My question is, can it be possible to do one on a auto loan do to a financial hardship as well? Or lower just your interest rate or something. I hear that car dealerships are doing really bad due to the economy, I wonder if this is something they can offer?

No. Getting your home foreclosed on is a much bigger problem than not making your car payment and having your car repossessed. Don’t look for the government to bail you out of every situation you may find yourself in.
If you are in danger of a loan default or repossession, you should talk to your loan company or bank (not your dealer) immediately to see if they can offer you any kind of relief.
