Lifter failure of the Jeep Grand Cherokee 5.7L MDS hemi engine appears to be a pattern failure and a very expensive fix. The exact cause seems to be undetermined but the needle roller bearings of the lifters sieze wearing a groove into the cam shaft and a misfire is then recorded. It happens to the lifters of various cylinders. The repair costs roughly $6-7k plus. Obtaining the replacement lifters is also an issue causing months of delays in repairs, and it would seem a fair assumption that scarcity is due to the number of replacement lifters being required. My vehicle is a 2011 with only 130k kms and well maintained.
If the vehicle is out of warranty Jeep will not fix this issue period. If anyone has news of a class action law suit on this issue taking place count me in and pass it on.
