  • 78,000 miles

Had the head gaskets replaced 2x and the engine heads machines and the cylinders machined. Stupid thing -- decided I had better get rid of it before it got rid of me.

Wrangler JKU 3.6L

  • Automatic transmission
  • 60,119 miles

2016 Jeep Wrangler JKU with 60119 miles at discovery of issues by dealership, Jeep was purchased new from dealer. Chrysler was contacted by dealership and myself to cover maintenance on blown head engine head gaskets following inspection ($13,000 to repair)

On 23 Feb 20 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. Not having any other problems or temperature change I parked my car at home. No more than an additional 3 miles were driven. The following day I contacted a dealerships to check for maintenance and was advised to bring it in if derivable.

My vehicle was driven to World Jeep in Shrewsberry NJ where it was determined my head gaskets are damaged and a repair was necessary. The dealership recommended the additional replacement of the radiator which Chrysler was informed of and discussed terms for covering the repair of the vehicle as the failure occurred right at warranty. Following the maintenance and repair I drove my vehicle home and submitted the paid bills which a Chrysler rep had discussed for payment.

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. Following replacement I drove my vehicle home attempting to drive it later the next day when I found my vehicle unable to start. 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. 10APR20 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. This is my 3rd Jeep wrangler and I am unable receive appropriate assistance from Chrysler/Jeep for a failed component that caused catastrophe damage over a long period of time only to be noticed at the end of my warranty.

Chrysler has switched case managers and told conflicting information with a limited response for a problem that has occurred in multiple jeep wranglers and is not an uncommon problem

Wrangler Unlimited 3.6L

  • Automatic transmission
  • 25,126 miles

In June 2017 I took my Jeep in for a recall and loss of coolant. They said the coolant loss was due to a bad radiator cap. Eight days later it got towed back, due to coolant loss. Dealer stated at that point the new organic purple coolant was evaporating. July 11,2017 it returned after two more stops to have the coolant filled...now they say the head gaskets need to be replaced. Two more trips after the head gaskets a FCA tech advisor looks at it, states nothing is wrong. FCA then told me nothing more we can do. That was on 10/4/2017...now January and I am still adding about every 1000 to 2000 miles.
