There's one sure way to get results, take all of your documentation to a lemon law attorney and have them fire off some correspondence to the dealer and Chrysler's regional rep. It may piss the dealership off - so be it - but as sure as I sit here it will be taken care of in short order. They know the next thing that follows is a lemon law suit. I would even bet you get a loaner for the duration of the repair. The repair may consist of a tear down or a complete service replacement engine depending. If there's resistance however, then this could be a long drawn out process and involve litigation. You pay no money out of pocket and if you don't succeed there's no cost. If you prevail, the attorney takes a set amount. I've been down this road with a vehicle, dealership, and manufacture. It was worth it and I prevailed, but it took time because the California dealership filed bankruptcy right after my judgment, I then had to go after the manufacture. It all worked out in the end.
