I've been getting the run around from 2 Jeep dealers on the engine "ticking" noise since I first bought it. Just 3 months past the powertrain warranty when a fellow jeep owner told me of the systemic issues with the rocker arms and bearings. Researched the issue, brought my jeep to a different dealer in home town and they immediately diagnosed issue and replaced all rocker arms....runs like it never had before. Now fighting with FCA on good will authorization and that is pain beyond most peoples endurance, except if your a grumpy old man!! Anyone fight this battle?
