We have a 2020 Jeep Gladiator with the 3.6L gas engine with under 63,000 miles. It has always been maintained at the Jeep Dealership in Fargo, ND since we purchased it when it was one year old. During our last oil change/service we were told there was an issue with the rocker arms and likely the camshaft. We had them do the required service happy that it occurred while still under warranty, just under 60,000 miles. The repairs were made and we drove it about 2,000 miles when the Jeep started to overheat. We pulled over, had it towed to a nearby repair shop, not a Jeep dealer, there was not one close by. They checked it out and noted the main coolant feed had failed likely due to high pressure, according to the tech it is suppose to this. They noted there are serious issues with the engine that will cost a significant amount to repair. The miles the Jeep has on it now puts us just out of warranty. We are having it towed to the closest Jeep Dealership for them to look at. Because we have always had the Jeep serviced at a Jeep dealership and we use exclusively on road we are surprised to find we now have serious engine issues with mileage just over 62,300 miles. This current engine failure certainly should not be expected as normal use wear and tear byproduct and must be because of an underlying problem. The shop suggested that the recent camshaft/rocker arms repair likely is a cause or contributor to this engine issue, noting they repairs to the camshaft would have included disconnecting the main coolant feed. Has anyone else had a major engine issue after the Camshaft/Rocker Arm repairs? Any advice or experiences you can share are appreciated, anyone who can shed light on this or @JeepCares will see it.
Update, The Gladiator has been at the Jeep Dealer three days now. We know both head gaskets are bad, the shop is working with Jeep engineers to determine the proper repairs to make. Plan to keep people here updated on the status and progress. No answer as to why this would occur.
5/15 update: we are now past the teardown, are being told both heads are warped, we are being asked to decide between doing repairs on the heads or a compete engine replacement before Dealer/Engineers will decide to participate in repairs. We did request a full ECM report that wpould show the history of code and event for the vehicle. We received a summary scan and have been told we cannot get a full report, if we want one we need @JeepCares to provide it, seems strange as I thought that need to be run from the vehicles ECM scan port. Hard to make an informed decision without all the facts. The conflict between JeepCares and the dealer are constant throughout this process
The summary scan shows a P0300 fault, multiple cylinder misfire about 110 miles before everthing went array. No codes from the engine heating up or check engine lights from those event. As soon as she saw the temp rise she pulled over. when it would not go away even after adding fluid we had teh Jeep towed. Anyone know if a full ECM report is available from Jeep ECM? I know other brands can produce a report that shows everything during the life of the vehicle. Feel like the rocker arm/Camshaft replacement was valid but there was more going on inside the engine at that time, even told our local dealer at the oil change the engine still was making noises. In hindsight we should have pushed harder on this at that time, it was still under warranty then.
