The Pentastar engine is used in other vehicles and has a pretty good history - read reliable and durable here. The was one small batch of engines which had head issues but this was caught by Chrysler and in reality is just a small blip on the radar. The auto also appears to be vice free.
I would not buy a diesel Jeep except if I was turning them over regularly and they were always under factory warranty. These engines are problematic - swirl motors, electronics. A manual diesel Jeep also has a dual mass flywheel too which is far too light duty for the diesel - many wear out prematurely and it is major dollars to repair and is not covered by warranty. The petrol manuals do not experience these premature wear rates.
The other thing with these diesel Jeeps is that spare parts from Chrysler are unobtainium. There's more than a few sidelined due to parts non availability.
If you want a Rubicon be prepared for a very long wait with no guarantees. These are so popular in the USA that production is going to fulfilling local demand.
Even the petrol JK Unlimited Sports have a waiting list here in Oz if you want one of the more popular colours.If you're not that fussy on colour - read limited options - then you will get your Jeep pretty quickly from Aussie stock.
Anything else I can help you with?
I live in North East Victoria lambrover- why?
