2018 Jeep Grand Cherokee Trackhawk fuel/propulsion system problems

“Three concerns: (1) the engine light is on. mechanics cannot determine why. (2) the car has trouble starting. When I park indoors, the car doesn't start. The engine turns over several times and the RPM goes all the way up, but the car will not start until the 3rd or 4th try. mechanics cannot determine why. (3) when I pump gas, the fuel pump automatically shuts off even though the gas tank is not full. So I have to hold the pump in place and use the gas gauge to determine when the tank is full. mechanics have seen this problem in other jeeps but haven't given me a reason why.”

“I have been experiencing slow crank issues for months now. The vehicle will have a slow crank then start. If it does not start on the first try, it will start on the second attempt. This concerns me as I've read many complaints regarding high pressure fuel pump issues on Jeep Grand Cherokees. I am concerned about my safety especially being stranded at night time. I was told I need to change the fuel pump. I called the dealership and was also told that many Jeep Grand Cherokees have been experiencing the same issue which was fixed by replacing the fuel pump. If many vehicles are experiencing the same problem, why is this not considered a recall?”

“I bought a 2018 jeep grand Cherokee limited on July 1,2024. A week after owning the vehicle the jeep kept shutting off while driving on the interstate and the dash said “ put in P and push to start” none of the hazard lights came on. It just automatically shut off in the middle of traffic multiple times and when put into park and tried to restart it would take several attempts. This is unsafe and I’m lucky I did not get into an accident since the vehicle is just turning off while I’m driving on a busy highway not to mention almost getting into an accident since I’m given no warning. I dropped off my jeep at the dealership and they have had it for two weeks stating they can not find any issues with the vehicle. This is frustrating and scary and do not even feel comfortable driving a the jeep that I owned for one week. I have read several complaints in the same issue and k won’t seems to be able to find what is causing this issue.”

“At around 66,861 miles my car started to do a weird shaking, slowing down on highway, rattling, and missing. I brought to dealer and they stated I needed an EGR valve replacement. This was done yet the code did not reset and the problem happened again. Now, I’m told well my vehicle needs an egr cooler!??? What is this? And why was this not communicated to me before I had the work done. Also, why would this malfunction so fast. This was July 18, 2022. There are no recalls but there should be with this happening so soon? I have children and this is scary on the highway.”

“Intermittent extended crank on cold starts and developed a misfire in cylinder 3 and the developed a misfire and coolant leak in cylinder 1. The dealer told me it needs a new engine due to internal engine failure. Codes p0303 and p0300. Engine only has 62,000 on it.”

“The alternator is pulling from the battery draining it and at 9.5 volts the car will go into safety mode where it doesn’t turn off but it won’t drive neither which actually happened to me on Saturday in the middle of the street luckily no car hit mines and the police helped me move it out the road. I complained to CArMax Kearny mesa the previous Friday and instead of them putting me in a loaner car and towing the vehicle they scheduled me for an appointment Monday (today) at 9:30am and never held up their end and I’ve been carless ever since and they had my car for 6 months fixing this same problem I’m having today .”
