Bought brand new back in 2012. 63,100 miles on it. Take excellent care of it. Last Thursday as I was making an idle-slow u-turn out of neighborhood, jeep shuts off. No lights came on, no vibrations, no noises. Turned the key off and restarted no problem. Happened again on Saturday as I was sitting at a stoplight. Just took it in to Jeep dealership and they said there were no codes and that there was nothing they could do about it. Anyone else have this same issue? Frustrated because they didn't even want to check the battery and I haven't changed the battery once in 5 years?
