When crossing the border into Mexico the AEB module falsely reports it has malfunctioned due to "geo fence" limitations. At least that is the cause of the issue per the service department. This causes the AEB system to stay offline and inoperable which also affects the Lane Departure Warning System as well as prevents the use of Adaptive Cruise Control. Supposedly there will be a "Software Update" coming--it was supposed to happen in Q4 of 2023 and now they say Q1 2024 which has ended and no update. The safety of the vehicle is compromised as key safety features are offline.

When starting and stopping the engine an awful noise is heard, it sounds like metal is grinding for about 2 seconds. Also on one occasion the electrical system seems to go haywire, as my power lift gate would not work. I tried several things to include turning the vehicle on and off, pressing the lift gate button several times, pressing my clicker, and pressing the lift gate button in the cabin area of the vehicle, to no avail. I finally had to pull the lift gate down, while this was occuring the inside the vehicle on the lift gate lights would turn on and off it was the strangest thing.
Screen froze while driving and prevented back up camera from working. I have taken it to the dealer multiple times for this issue and they stated they can not duplicate it so no action was taken.

The vehicles climate control/hvac system has inadequate ventilation that prevents air movement to occur. In cold tempatures all all of the vehicles windows fog and ice over form the inside. This results in the driver loosing visibility out of any window. During cold weather conditions, the rear passengers, windows, and rear wind window, even with defrost drawn ice up immediately along with the double moon roof. Problem limits, visibility, making the vehicle, unsafe to drive due to the limited visibility caused by this inadequate and design deficiency. There are no heating system vents besides in the front dash of the vehicle due to the moonroof. The rear climate controls do nothing to remedy of the issue. When I reported the issue to JEEP corporate immediately after purchase, they acknowledged the design deficiency, and that they were working corrected for future models. This is unacceptable and creates a hazardous driver condition for any vehicle. Had I know this prior to purchase I would have never bought the vehicle as there is no remedy.
Dashboard showed Transmission Error Message: Service Transmission Continue in D, Do Not Shift or Turn off Engine Until you Reach a Desired Location, You may not be able to shift again until serviced. Vehicle was stuck in 1st gear and would not shift out for 5 minutes. Taken to dealer with engine light on and shown pictures of error messages and dealer found nothing wrong with vehicle. This all happened on a highway and I had to navigate from high speeds to slow and stop in the exit lane.

On 10/07/2023, about 7:30 pm, I was driving down 6th Street in Beaumont California at about 30 mph speed when all of a sudden the engine made a horrible loud noise and it looked like the accelerator pedal was suddenly hit. It seemed that the vehicle speed did not increase accordingly, but my foot had released the gas pedal already. Once I confirmed that the noise was indeed coming from my car, I pulled over and turned off the engine while the loud noise was continuing. Then I restarted the car and the problem didn't reoccur this time. Then, the car has performed normally.
Driving Screen, Swaybar Disconnect systems, Airbags, TPMS, Driving controls such as blinkers, and emergency flashers. The car was functioning normally, with no anomalies or error messages, including through phone notifications. The battery charge was nearly complete. I engaged Electric-Drive mode and used regenerative braking to recharge the battery on my way to town. Approximately 30 minutes into the drive, and with the battery at 99% charge, I heard a loud pop. It sounded like it was coming from the right-side passenger control arm. Shortly after, my dashboard was illuminated with warning lights, including a check engine light and notifications about air suspension and sway bar disconnection, airbags, tpms sensors, and more. The car decelerated dramatically; The dashboard screen flickered on and off as if rebooting. I got the vehicle safely, but during that time, the car seemed to be in limp mode, unresponsive to acceleration, and stiffer than normal breaking. The steering was also affected. I realized that if I had been on the highway, this could have caused a severe accident. Screen, Powertrain, and drivetrain fail while traveling 45+ miles an hour. It is a small 2-way road in turn with mild car and foot traffic around. The dealer has confirmed the issue as an issue that has been present in past vehicles in this model category. The car had been in my possession for less than 24 hours/40 driven miles.
Making left hand turn through 4-way intersection. Car opposite of us also making left hand turn. Our Grand Cherokee collision system thought the two vehicle were going to collide and locked the brakes in the middle of the intersection almost causing a 4 car accident. This is the second time this has happened since purchasing 06/03/23. Driver neck injury sustained. Seeking medical attention. Jeep is currently at the dealership where they are trying to reproduce/diagnose with no success. Multiple online articles found showing complaints of this EXACT issue proving it's not isolated to our vehicle. https://https://wljeepforum.com/index.php?threads/2021-gc-l-came-to-dead-stop.1467/

The uconnect system on this vehicle locks up, glitches and is unresponsive. This makes the hands free function for cell phone use unreliable at best, as well as all touchscreen functions inoperable. The problems with the uconnect systems make driving the car very distracting and potentially unsafe at times. These problems have been inspected by the dealership service department and confirmed not to be normal. The dealership service technicians have attempted to fix these problems four times by replacing two radios, a touchscreen and reloading software. None of these attempts have been successful. The uconnect system has had these issues starting the first week of ownership Nov 2022

-The front and rear camera work intermittently, and yes it is available for inspection upon request. - During the morning, afternoon, or during the night, the package that includes the security that the vehicle has about vision by cameras does not work, putting their own lives and others at risk by not seeing the blind and low spots from the Jeep Grand Cherokee Summit Reserve 2023, causing a fatal accident. - The has been confirmed by a dealer because me personally and my wife have delivered the Jeep Grand Cherokee Summit Reserve 2023 with the problem in its maximum expression to the dealer. - The vehicle has been inspected more than eight times, but the dealer technician and Chrysler technician don't know yet how to fix the problem.

Bought the vehicle new. At around 3000 miles the vehicle dash had all dummy lights on and giving me all warnings. Then while driving the vehicle dash started flashing on and off and the vehicle started loosing power. Has been sitting at the dealer for 2 months. No time when parts are coming and if it's fixable. Advised to contact Chrysler and already did. Keep getting round around and case numbers with no resolution.
When ever I try to charge my Jeep grand Cherokee 4xe summit reserve it fails to charge on a level 1 or level 2 charger and then they check engine light comes on and a electrical burning smell from the hybrid battery and says service charging system. When ever you bring it to the dealer they just reset the code and says it works only for the problem to come back it also affects how the jeep drives when this happens the jeep doesn't want to accelerate properly and has other electric system issues like the wipers coming on randomly and the massage seats coming on randomly as well which can distract someone when they are not expecting that to happen the jeep doesn't want to drive. I brought it to the dealer 3 times now and all they keep doing is resetting the code and stating its fine only for it to come back and this is a major problem and needs to be fixed as this is going to cause a major accident or fire since it has to do with the hybrid battery system.
The Uconnect 5.0 screen (which controls all safety and operating systems) and system continues to malfunction with a black screen. This seems to happen more frequently when the car is put into reverse and the backup camera is activated. There have also been times when the screen freezes requiring a "reboot". Thus when malfunctions occur, there is no backup camera nor is there any ability to operate safety systems. This seems to be occurring every single day. So far dealer has been unable to replicate problem and thus cannot repair it.
We have been without service of the Grand Cherokee L vehicle for nearly 6 of the 11 weeks since we leased the vehicle. The four (4) incidents and -??repair attempts-?? to -??fix-?? the randomly/sudden occurring mechanical and electrical problems were inter-related and causal to the mechanical and electrical blackout troubles. 1.02/27/23 Purchase 2.03/20/23 631 total miles traveled. Dash board blackout. a.Service Dept -??reset software-??. 3.03/31/23 912 total miles traveled. Complete dashboard, radio and navigation blackout a.Service Dept did not experience random failures, -??therefore no repair action was warranted-??. 4.04/01/23 930 total miles traveled. While traveling at approximately 45 mph vehicle suddenly seemed to drop gears - the rpm went from 2k up to 6k, the suddenness of the drop of gears had our seat belts tightening. pulled the car to the side of the round and car remained at 6k rpm. I turned the car off, waited a few seconds then restarted the vehicle and proceed home. 5.04/02/23 after starting the car remotely car literally would not get out of automated start mode. I had to turn the vehicle off, wait a couple of minutes before it would start again. In driving the vehicle to the repair shop the power went out of the radio/gps/etc system again. a.Service Dept found RADIO with internal failure. Ordered replacement radio.-?? b.On inquiry, Service stated the CAM bus (software version -??AG-?? was replaced with updated -??AI-?? version.) 6.04/26/23 1,051 total miles traveled. On exiting a parking lot, I tried to accelerate into traffic, the RPM increased but with zero forward motion. I pressed the accelerator to the floor, the RPM increased but zero forward motion. I then released the accelerator, the RPM correspondingly decreased - still no forward motion. Then reapplying pressure - slowly to the accelerator - the vehicle began to roll forward but at an EXAGGERATED slow pace. I slowly rolled across the traffic lane and forward "running rough".
Incident #1 - Power steering issue. While exiting the driveway, I lost power steering along with unresponsive controls such as "lane management" and "traction control." Alert on dash read, "power steering unavailable, " and engine light was on. After turning the vehicle off, power steering and other controls returned after about 20 minutes of occasionally turning the vehicle off and on again. Service was performed with a "software update." Incident #2 - About a month later, while driving on the road, I abruptly lost power steering and the ability to accelerate, as the gear shift disingaged and was unresponsive. I pulled over to a rolling stop and tried shifting gears but the gearshift still would not respond. I then turned the vehicle off, waited a few seconds, then turned it back on. After doing so, all controls were restored. I didn't check for warning lights. The vehicle was not taken in to get serviced. Safety risk - Had these malfunctions happened on a busy street, it definitely could've caused a serious accident, as my control of the vehicle was very limited. The vehicle is available for inspection.
