Starter went out, it was covered under warranty. I was told there was a recall so it was replaced. 3 days later engine caught fire. I had it towed to LITHIA Hyundai in Fresno. He called 30 minutes later saying engine blew and I may have blew a rod. I said how did that happen on this new car when you told me when you fixed my car 3 days earlier that everything was okay including my oil. He said I would have to prove to him I had oil change. I said I have maintained my NEW car. He said is he just suppose to believe me and I then said how do I know something didn't go wrong when starter was replaced. He said we are not going to go back and forth. I am still under warranty. They refuse to do diagnostic. My insurance will not cover mechanical. My car that I'm still paying for is still sitting in service dept @ Lithia Hyundai.
