So I think that my sonata is not certified like the dealer said it was. I bought the car at a hyundai dealership and told me it was certified. I was given a pre-owned certified check list but missing a cpo manager signature. I call Hyundai corporate and was given a case number. They told me the car is not certified and would call the dealer to find out more info on my car. Corporate calls me telling me that the dealer in fact is stating the car is certified and are doing the paper work necessary to make it certified and then give it to corporate. Corporate is telling me that they will leave the case open untill its certified. My contract say used and not certified. I really think that my car in not cpo and will not get it to be cpo. All i have is a check list and corporate having notes saying the dealer sold it as cpo. Can I return the car if not cpo. What can I do. They are supoose call me this coming week. The dealership I bought it from was really shady. I wish walk away and did a couple times, but got me at the end.
