2012 and newer had the penestar..was not a bad motor except for some of the earlier ones where there was some sand left in the head castings. The 07-11 motor really sucked, had it on my 08 minivan and it would "lose" (never saw any smoke) a quart per 1,000 miles since new. I could not believe it when the wife came home and said the oil light was on....it took 3.5 quarts to refill. Chrysler said it was WELL within their normal tolerance!!!
