I have a 08 and it's been a oil eater from day 1, it pings like crazy,and it's guttless.. Biggest pile of shit engine I've ever had. Not to mention it pops out of 3rd gear,the rear end is worn, the top leaks, the tailgate hinges are worn out,the cruise control stopped working,, the list goes on and it only has70,000mi on the clock...pretty capable off road but other than that the jk is a pile of shit, I mean really, who puts 3:21 gears in a jeep? The thing would do 150 mph if it had the power but you have to slip the hell out if the clutch just to get it off the line.. Chrysler has ruined a good vehicle in my opinion
