I purchased a new 2012 4 door rubi last year installed lift And 35s plus many more mods , love the build process and it's 4x4 capability and rolling around topless . It ran trouble free for awhile until around 10,000 miles am just starting to experience engine tick , talked with dealer and was told to drop it off and they would let me know when it was done . After reading in great detail all of the 3.6 treads I question it's reliability , I would have know problem if it was a toy , but As a dd not for me . Had fun guys thanks for all your input and answers to my question over the past year
