2016 jeep wrangler jku with 60119 miles at discovery of issues by dealership. Chrysler was to cover maintenance on blown head engine head gaskets following inspection. On 23feb20 I noticed excessive vapor coming out of my exhaust on my way home, I checked my coolant and oil to see if there were any problems finding low coolant levels however it was still within normal range. It was determined my head gasket was damaged and a repair was necessary. The dealership recommended the additional replacement of the radiator which chrysler was informed of given terms for covering the repair of the vehicle as the failure occurred right at warranty. I found the engine was still having a problem with air in the radiator/coolant line and immediately took my vehicle back to the dealership for a coolant purge. During inspection the chrysler master mechanic noticed the main coolant fan was not operating as expected. The main coolant fan operation was intermittent which would have caused a long term overheating as the root cause failure of the head gasket which was to determined by the chrysler facility to have been failing over the last 10,000 miles. Chrysler was contacted and approved maintenance as with the other failed items. I contacted world jeep again and was able to start my vehicle and drive it to the dealership for maintenance inspection. Dealership found gasket installed was defective, the heater core was clogged unable to provide heat in the cab and the engine had a knocking noise. Chrysler was contacted to recommend course of action which is the replacement of the engine. Chrysler has changed case managers 4 times and has been difficult to receive a response back by myself or the jeep dealership. Chrysler is now refusing to cover any of the work they had previously agreed to help cover and are only willing to assist with 50% of the repair costs of the engine replacement.

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 federal safety agency for a solution.
