The 5.7L Hemi is a great engine. It paired with the 545RFE transmission and you will be on the road for quite some time. I have 120k miles on mine and have had no engine problems whatsoever. Vary rarely do we see any problems with these engines here on the forums. 2010 JKU - Stock for now.
i have recently purchased a used 05 hemi 5.7L grand cherokee limited. after a week of owning it, i noticed "SERVICE ELEC BRAKE SYSYTEM" displayed where the speed odometer is and along with the picture of a car with kinda like skid marks behind it.i later learned that the picture was something to do with the traction control. this display and picture would apear at first once or twice a week

Re: Wk/Wh 2005~ Grand Cherokee Common Faults And Issues. Marlin said: Updated with; 5.7. - 05-07 models have delay issues with electronic throttle. Dealer rplaced MAP sensor on inlet manifold and installed updated throttle pedal (requires wiring modifications as it's a new design). Can report it is much better now.
Checked cylinder 2 compression, cause it was easy to get to, just to check my gauge and I'm getting 160 on cylinder 2. Lining up a shop to look at it. 2006 Jeep Grand Cherokee 5.7 hemi qd2. 96,000 miles. No issues,besides the qd2 recall flash problem, since I bought it with 38,000 miles. Never overheated.

My 2021 Hemi WK2 has a recommended 10K mile oil change interval and at the end of 9600 miles the blackstone report clearly shows the oil was ready to be changed, but was not wildly over-due. This last oil change was a bit sooner, more like 8500 miles due to timing of trips to NH and Vermont.
