I would take it to someone you trust or ask around and find someone you trust to check it out for you. From personal experience with Chrysler with my jeep I wouldn't hold my breath in getting a new engine, which is what should of been done IMO. My transmission went out on my 2010 JKU at 59,000 miles. I thought the lifetime powertrain would cover it. I checked and mine did come with the lifetime powertrain but since I was not the original owner it was nontransferable to me. Then they went on to tell me that the transmission cooler from factory is pretty weak and really needs to be upgraded to a bigger one to prevent the transmission from over heating. Even after telling me all that they still stuck me with the bill and I'm not talking about a stealership, I'm talking Chrysler corporate. I even asked if they would pay for labor or something, no go. So I ended up with a jasper transmission, which IMO runs better than the stock transmission I had in it and my mechanic added a bigger transmission cooler to it as well. Total cost was $2700, and it came with a 3yr 100,000 mile warranty. I never thought about getting rid of it, I love it to much to do that.
