Look at your warranty. It "shouldn't" give you troubles right away unless you were sold a lemon. Is this a new or used car?
Bring it back to the dealer, and explain. If they refuse to help you, I would do what a friend of my aunt did. She took her lemon car and rode around the dealership with a sign: " This dealer sold me a lemon! " Some time later, she was offered another car!
The only true wisdom is in knowing you know nothing.
