I have had problems with my DJ shutting off while I am driving. I ran over some railroad tracks the other day and everything shut off. Then it will restart itself. It did that twice then the third time it would not start. I took it to the dealer but it started fine for them and they said nothing was wrong with it. I had this problem a couple months ago and replaced the battery and alternator but now it is doing it again. I see there is a recall on the 2010 DJ for this but not the 2011.
