I have had no problems with this jeep.
The only thing I see as a weakness is its power seems to be weak.
The power its not weak it does what its made to do I have a 2006 Rubicon and I must say it can pull almost anything out of mud pits and sand pits I haven't found something I couldn't pull out it's a great truck I love it, but gas wise it sucks I must get like 10 miles per gallon I fill up 2 to 3 times a day which sucks, but its worth it as long as I'm enjoying it.
