If you turn in your vehicle to the dealership and you file bankruptcy will the debt be discharged?

Uh, why do you think the dealer you bought it from is involved? He may have helped arrange financing for the car, but you most probably owe an entirely different lender for the loan. The dealer can't really touch the car...leaving with him is the same as abandoning it on anyones property..they will just call the police and have it towed away...and you'll have to pay any fees and tickets incurred for that too, sooner or later.

You really need to get some personal professional/financial/legal help.

Bankruptcy involves ALL your debts and ALL your assets...not just your car loan.

You may be required to file a Chap 13 and make payments for several years.
