The car lender is taking the car back because I m a temp worker & the dealer can t do anything to help?

I just recently got a car from Honda. A 2008 Honda accord & they told me to put $250 down to get the car. I have only had it for 2 weeks. The bank wants the car because im a temporary worker through an agency. My car dealer knows that i am because i told him & my paycheck stubs say the service name. I had a car i traded they cant sell me it back or are making me sign a finance paper for 3 years & i only had 1 year left. Now they are forcing me to get a car with a lot of miles & bad breaks & its a 2006 Toyota Corolla. They didn't pay attention to detail as they sold me it now if i dont take a car I'm car less. Should i sue the dealership for financing me a car & not paying or just go ahead and do a lease for a car? Help please
