Got a 2011 JK Sport and had some problems about a year ago soon afterI got it. It was powering down(ETC light coming on when it happens). All I did was pull over and restart it and I was fine. I took it to the dealer and they said there was no problems. I haven't had any problems since then.......until now.
It has done it 2x's in the last couple weeks. All but once it has happened when I was on the highway when I had my cruise control on. I am going to take it to the dealer again to see what is going on. Anyone else have any problems like this!!
