I have had many problems with this vehicle. Apx 50k miles the water pump blew. Had it replaced - then apx 75k miles I experienced jump starts - took it to the dealer who was only doing oil changes that day. Took it to aaa repair center - they did a pressure test - found nothing wrong. Experienced the jump again - took it to a firestone mechanic who did a pressure test and "found nothing wrong". The Jeep would not start on thanksgiving - had it towed to the aaa center where I explained what had happed. They discovered that the head had blown and was now warped & camshaft broken at considerable cost, they fixed it, but now I have a p0340 code (camshaft sensor). I let the vehicle sit overnight. It seemed to start fine. After 40 miles of highway driving the oil light came on briefly, before shutting off.
