What Owners Say
""Due to a failure of the computer part that monitors the mix of gas, air, and the fluids in the engine, the cooling system failed. The failure led to an immediate overheating of the engine. The engine did not seize but it was obvious to the mechanic that fluids that should not be in the cylinders was present. The engine was a total loss and required replacement.""
Anonymous A., MA (2014 Jeep Grand Cherokee Limited Unsure)""The 6.4 engine has a serious design flaw that limits the amount of oil the cam shaft receives at idle as well as when the engine goes into MDS mode. Happens around 90,000 miles. It starts with the lifter roller issues.""
Anonymous A., AK (2014 Jeep Grand Cherokee SRT 6.4-L V8)""Its resolved now after paying 13,000 for a new engine""
Anonymous, ND (2014 Jeep Grand Cherokee Overland Unsure)"Repair required tearing down two levels into the engine manifold to replace the oil filter housing assembly and 12 cylinder gaskets."
Anonymous, TX (2014 Jeep Grand Cherokee Limited 3.6-L V6)"The lifters and rockerarms are the major problems with this engine .It will be 12 years that I've been driving this vehicle and it never left me on the side of the road.I would not buy it again because jeep knows the probelms but refuses to make do what is right. Unscruplus mechanics will also try to convince you that you need a new engine and charge youfor a new or used engine and then make repairsto your engine and tell you that you have a new engine .The dealership told me I needed to replace all rockerarms and all lifters at a cost of 3500.00. My mechanic found 2 lifters that were bad and the parts were less then 30.00 dollars."
Anonymous A., GA (2014 Jeep Grand Cherokee Laredo 3.6-L V6)""The early year eco diesels (especially 2014 through 2016) are notorious for their failure due to excessive soot fouling. Even though I bought the vehicle with less than 100,000 miles, and had the coolant system failure at 102,000 miles, the independent repair shop alerted me that they may have to replace the whole intake manifold, if it is discovered to be heavily sooted (which in the vast majority of EcoDiesel vehicles manifests). So when they started to break down the engine to replace the 4 inch piece of failed rubber hose, they confirmed the excessive intake manifold fouling which was going to add more than $1000 to the total repair estimate. Unfortunately, for them they tried to remove the number six glow plug and snapped it off. The remainder stuck in the head was not able to be extracted. That then led to a proposed solution which was going to require replacing the whole engine for an estimated cost of $12-$16,000. The vehicle is not even worth $12,000. While the repair shop bears some responsibility for this failure, the Lions share of responsibility lays at the feet of FCA for designing such a wholly inadequate and failure-prone engine design.""
Anonymous, SC (2014 Jeep Grand Cherokee Overland 3.0-L V6 diesel)"This is the eco-diesel engine. The EGR system introduced so much oily soot into the intake manifold that the intake manifold doors failed, causing poor performance."

""Car would start up and then "chug" like it's revolutions were too high, yet the dash didn't indicate that. Felt like it was going to shut down, which it did on some occasions. Check engine light came on intermittently. Dealer charged me nearly $5000 worth of fixes, but settled on a cylinder head problem. Yet the car definitely still does not run smoothly.""
