After driving approximately 30 miles on the interstate I stopped and went into a store. When I came back out in 5-10 minutes and attempted to started it, the engine felt as though it were "jumping". Had it towed to the dealer. They said it had dropped a valve seat. Chrysler determined that it happened because it had been overheated. However there were absolutely no overheat codes in the computer. The gauges have never read hot. It was not low on coolant. They stated that there were no leaks. It was never hot.
