Thoughts on frustrating situation.

First thing I would do is try and contact a dealership with the VIN and request the history. Secondly, slow your roll and see the warranty top to bottom... And then read it again. Unfortunately it only take one word, phrase, or stipulation to get you out of the requirements in regards to what the warranty covers. And unfortunately if it's your word against theirs, you could have no friend in the way of a judge.

If you have a Lemon law in your state, there could be something. It will vary state to state. When you were told about absolutely getting the warranty that should be enough to make you run or accept it could be a problematic vehicle. If the dealership has a record of problems and ending up in court that could be in your favor. But as we all know getting a judgment and actually receiving justice is not always in the same sentence.
