50 Engine And Engine Cooling problem

Failure Date: 12/10/2017

I was driving on the interstate and the engine just died. I pulled over to the side of the road and restarted the vehicle and when I put it in gear it acted as if it were in neutral. I then shut off the vehicle and restarted it and it drove fine. This happens randomly (could occur twice in one day or not for 2 weeks) and at different speeds (city and highway). I also have had random misfire codes and camshaft position sensor codes. Sometimes the codes clear on their own and I have had to reset the codes with a tuner. I spoke to the dealer and it will be around a week before they can look at it, even in light of the danger for an engine just dying.

53 Engine And Engine Cooling problem

Failure Date: 08/15/2016

Engine ticking on left side. This seems to be a common problem with the 3. 6 penstar engine. I've taken it to two different Jeep dealerships and both of them said pretty much that this is something I'll just have to deal with. That is totally unacceptable. This was over a 30 thousand dollar investment. This Jeep didn't have this problem when I purchased it otherwise I wouldn'thave bought it. Looking to the NHTSA for a solution.
