I have a 2007 Jeep Wrangler and I have had continuous problems from it. From about 2000 miles till now 12000 miles I have had stalling problems. Usually while doing 65 or better on the interstate. It happens at different times not predictable at all. I brought it to three different dealerships and called a few extra. No one has heard of it and said that it checks out fine. I recently moved to alaska for my career and drove the Jeep up here. It stalled three times on the way up here. All at speeds 55 or higher. And in oregon the Jeep began making loud noises at low speeds. I brought it in there. They said there was an abs recall and reset it. No explanation for the stalling. The stalling and noise still continues. First week in alaska my park quit working. 5 days later works fine. Dealership has no answer of any of the problems. To them it worked fine. It has a mind of its own and unfortunately it won’t do it for them. I even suggested they keep it for a few days but they wouldn't. I called Chrysler they said it needs to be diagnosed with a problem before they can help me out. I read similar problems with other owners on a forum and they said to contact you guys.
