Rocker arm bearings went bad, need to replace all rockers and perhaps a cam or 2, this is know as the Penstar tick due to poor quality metals from Chrysler . They need to do a recall and fix for all affected cars as this is a labor intensive job and could cost up to 3000 dollars in repairs!

Hard shifting car jumps when put in gear I think it’s a known issue with this vehicle
My car goes into neutral on its own.
Slipping, feels like transmission is going bad
On the highway my 2015 Jeep Grand Cherokee Diesel briefly stalled and the check engine light came on. I then lost all power and could only maintain a speed of 45MPH in a 70MPH speed limit highway. I turned on my flashers and could not get off the road due to construction and Jersey barriers for several miles. When I had the opportunity I pulled off the side of the road and called to have my vehicle towed to a service facility. I was informed by the mechanic that scanned my car for trouble codes, a P0336-00 was set in my PCM. The mechanic informed me that I would have to take the vehicle to a Jeep Chrysler dealer. This is apparently a known issue with 2014 to 2018 Jeep Grad Cherokees equipped with the 3.0L diesel engine including RAM 1500s of the same vintage with the same diesel engine installed. The specific problem is that the crank shaft tone wheel is not read by the crankshaft position sensor because of degradation to the tone wheel which is connected to the crankshaft. I have complied with all safety and emission recalls. Related: RC-RW68-20 Safety Recall W68 Transport Canada 2020-371 Loss of Crankshaft Position. Requires the replacement of the Tone wheel. Issued 02/11/2021. RC-RW58-20 Safety Recall W68 Transport Canada 2020-371 Loss of Crankshaft Position. Requires PCM Software update for Loss of Crankshaft Position. In lieu of the Tone Wheel failing, the computer uses the Camshaft Position sensor. This is only designed to not disable the car completely but allow the driver to pull of the road. P0335-00 or P0336-00 wil be set and a check engine light will illuminate. My vehicle was not included in the NTHSA Safety Recall and it should have been.

2015 jeep grand cherokees going into neutral on occasion while driving at speeds above 45mph. I brought my truck to jeep and expressed my concern about this safety issue and my safety. I was informed by jeep there is nothing wrong with my jeep since no codes are showing. I asked to speak to the mechanic and the mechanic told me that there is not one problem with that jeep and the 8 gear transmission is the most stable. He then said you probably put the jeep in neutral while driving. I was completely frustrated with his response and said to him, do you think I would put my jeep in neutral while driving 55mph and risk my life and possibly someone elses? I left the dealership very upset as you can imagine. A few days later it happened again and I contacted the jeep dealer to let them know the issue. Never heard back from them. I was also given the email of my service manager. I sent him a video of what happened after the car went into neutral. I also sent him links that I found online about other jeep owners complaining of their jeep going into neutral while driving. I have not heard back from the dealership yet. My guess, jeep is trying to hide this known issue. When the jeep goes into neutral the check engine light goes on and you cannot put car back in drive you have to coast to side of road. Try doing that on a 3 lane highway. Very very dangerous! Please look into this issue 🙏. I bought the car from carmax and carmax said I could have jeep look into issue. The jeep repair center reports there is no issue nor have they heard of any issue like this. If you google jeep goes into neutral while driving there are many threads about such incidents. I need help please. Upload link is not working but I have a copy of the invoice they have given me. [XXX] h INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

"Check shifter" seems to come on almost everyday. From what I've gathered about it it could shift out of gear while driving. Could be a sensor or harness issue that I was told by a mechanic. No incident yet. This should be recalled as it seems to be a common issue with this Jeep.

When stopping and suddenly accelrating jeep has a power delay and you have to hit the throttle agressively to get going or else I run the risk of getting hit by another car, but once you hit throttle the power is more than you need it or expected it, forcing me to brake or else I hit the pcar infront of me. I am still not able to make this work. I purchased the car used, I am still making payments and I barely use it because I find it extremely dangerous at time. The power doesnt come when I need it but when I do its too much, feels like I floored it and I have managed not to crash but its something someone should take a look at before its too late.

Th cylinder has low compression causing misfire in the vehicle. The misfire can cause the vehicle to lose power. If you lose power on a highway it could cause an accident. This has not happened to me, but I have read the cyinder issue is a common problem with the 2015 jeep grand cherokee Seems like bad parts. A mechanic has ascertained the problem with my vehicle. If this is a common problem why has the manufacturer not fixed the problem and inspected these parts?
Driving on highway 290 West near Waller. At 75mph I attempted to pass slower traffic by accelerating after moving into the farthest left (passing) lane when my Jeep lost power. Had to maneuver while coasting between traffic in lanes (frogger anyone?) to farthest right lane by coasting through to an exit by chance. Would not restart while coasting. Traffic line formed behind me for those also seeking same exit I needed at the last second. I was unable to fully move into shoulder because of debris seen and fear of damage to tires. After coasting to a full stop a quarter mile from Love's Truckstop, put vehicle in park, and was able to restart after hesitation. Engine light on with my reader stating "confirmed" codes P0336, U1401; and a "pending" code of P05ED. Now takes 3-5 seconds to start when used to be "instantly." In a nutshell, this was not fun. :| Note to manufacturer , please stop skimping out on quality.
