need a lot more info,
Did you buy this over the net?
How far way is the dealer ?
Did they claim accident free etc.
Did you check his background / reviews??
Possibly a case for BBB arbitration, their states DMV or Attorney general
What year model etc.
What did you pay with transportation ?

I would contact them ASAP in writing (Email is fine) about the problem(s) and do nothing else PERIOD until you get a response. It's a 3 day weekend so you may have to wait until Tuesday to get a response or follow up with a phone call.

As previously mentioned depending on the state there can be a lot of different resources available. AND NO DO NOT TITLE IT !
