If you own a 2012 JK, you might want to get it checked out. Major engine failure, currently 7,500 customers are waiting for new engines to be delivered/installed.

Yep, defective heads. I heard (without reading your article) that a portion of the head (s) have a casting issue with insufficient cooling.
The first sign is called "the Pentastar tick" (typically starts on cylinder 2).

I guess there's something to be said for the reliable minivan engine in the earlier versions.

Sound like the guy who thought 2 little Phillips screws to retain a brake disc were a good idea worked on that project...

Just to be an ass about word usage, I think we mean "defective" Pentastar engines. I don't think there's and danger of the Pentastars defecting to GM or Ford :)

Honestly, the 3.8 isn't exactly known for its bulletproof reliability either. Known oil consumption issues to the extent that Chrysler's official position is that burning 1 quart of oil per 1,000 miles is "acceptable." They'll get you to 100k, after that seems to be borrowed time.



....and I thought it would be a good idea to supercharge mine :lol:
