I've owned a Jk for a couple of years now and it has been stalling in 2nd gear the last few weeks. I gave the car to Berwick jeep service centre and they all tell me is that their computers doesn't show them whats causing it and that there is no problem.
Has anyone had this issue? i know its not my driving!!!

 

I just read an article (from Associated Press) about a recall for the 2011 Grand Cherokee and Durango for a fuel pump relay causing the same condition. (You didn't say what year you have.) However, there is a consumers group that has a law suite pending to have this recall expanded to include Wranglers of the same year. I would suggest taking it to a dealer for diagnosis, it may not be the problem, but it will send a trouble report to Chrysler.
