I doubt the engine is bad at 39,000. Did you have the inspection done at a dealership? If not, I suggest taking it to one and asking the service manager to just listen to it. If he says the same thing, then we need to contact Chrysler. The Jeep has a 5 year 100,000 mile power-train warranty. I realize this is year 5, but it will be based on when it was put into service. If it is only out by a short time, we need to do some complaining.
The engine, if bad, should be replaced by the manufacturer.
Let me know if you got it new. If you did, what month did you get it.
