2023 JEEP GRAND CHEROKEE L Electrical System Problems

The radiator fan failed causing the car to overheat.

The infotainment system/screen intermittently goes black.

Since I bought the vehicle in February 2025 I have reported the infotainment screen failure/ going black while driving. I immediately reported it to my salesman and had it assessed by my local dealership as well about it. They told me it was up to date and they could not find any codes and sent me on my way. Shortly after I realized the auto start/stop wouldn't engage and I also encountered a random subwoofer boom upon starting my vehicle at times. The electrical issue has been known by Jeep for some time as there was a technical service bulletin that circulated regarding these issues and there are numerous other issues that were reported as well on this bulletin. Bringing you to my recent experience was after bringing my jeep in twice after my purchase (when also under warranty) to address these electrical issues I was always told no codes, jeep is fine. It continued to be a problem but subwoofer got worse. Last week I tried to remote start my car and it just flashed rear lights and didn't start. It was completely dead. I was able to jump start it and got it to the dealership and they said it was the battery and replaced the battery. I had JUST had a new battery installed upon purchase in Feb 2025. Brought it home, same thing, it died. I noticed dash light going on and off and a chirping sound before it died again. Brought it back in. They say it was the door switch that's faulty. It's obviously an electrical issue and it will leave me stranded or others stranded. This is a safety hazard as it causes loss of display, loss of emergency calling, distraction, battery drain and unpredictable electrical behavior.

Malfunction of the Steering Column Control Module causing a disconnect with all associated components such as causing wipers to run continuously on max, and all listed functions stopped working including; SOS, Jeep Assist, blind spot, high & low beams, brake lights, turn signals, lane assist, horn, rear wiper, windshield washer fluid, airbag deployment, infotainment system, etc. Vehicle is currently at the Dealership in Delmont, PA and is available for inspection. This is a significant safety concern to myself and other drivers due a visibility issue with wipers on a continuous cycle, headlights and brake lights not functioning as intended, unable to use turn signals, airbags will not deployment in the event of an accident, among other safety related issues. The vehicle has been inspected for this specific issue at the Dealership December 21, 2023 and November 11-17, 2025, and was temporarily resolved with a software update. 24 hours later, on 11/18, the same issue reoccurred and is back at the Dealership with no update on a permanent solution. There are no warnings or symptoms prior to the failure of the SCCM. This issue first occurred 12/21/2023 with only 3,439 miles one it. The vehicle currently has 32,091 miles. Pictures and videos are available upon request.

Bought vehicle and reviewing safety features the next day I realized the Forward Collision Warning light was on because it was malfunctioning and not just turned off. Same with the AEB light. Then Active Lane Management came on as did ACC. This is a concern since they are all safety features. Took it to dealership and they unhooked battery to try and make the windshield spray work. After that all safety warning lights came on. Dealer has had it for 2 weeks and still cant figure issue. Looking online it apprears this is a major safety that happens to a lot of these vehicles.

Every time the vehicle starts, the driver dash display and radio display reset to a language I do not speak or understand (Italian). The paddle shifter is inoperative (with no option to enable), pedestrian emergency brake (peb) lamp or forward collision warning (fcw) lamp turns on with no way to disable, units of measurement changes to celsius, and numerous other settings reset as well. This is a dangerous situation. I don't understand the meaning of warning messages on the driver display because they are in Italian. It is difficult change the settings because the menus are in Italian. Plus, even if I change them, they all reset the next time the vehicle is started. I have taken it to the dealer numerous times. The dealer says there is nothing they can do and it can only be corrected with a software update that is not yet available.

Computer telling vehicle to do a sudden unintended acceleration. Forward collision warning system did not respond. Air bags didn’t deploy. No diagnostics have been done. No warning lamps illuminated on dash. Vehicle currently is at repair shop.

The contact stated that while driving at an undisclosed speed, the infotainment display was frequently powering off and on and failed to display pertinent vehicle safety information; however, the vehicle returned to normal functionality, and the contact continued driving to the destination. Upon the return trip to the residence and loading groceries into the rear of the vehicle, the liftgate started to close independently. The contact made several attempts to trigger the liftgate proximity sensor and pinch protection system to prevent the liftgate from closing; however, the vehicle failed to detect the presence of a person, and the liftgate continued to close. In response, the contact jumped into the rear of the vehicle to escape possible injury from the liftgate closing prematurely. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 59,000.

My 2023 Jeep Grand Cherokee L and intermittent starting issue. The vehicle would not recognize the key at times. After a while I was unable to start the vehicle without having the fob touching. Last week the vehicle you start and the shutoff when I tried to drive away. I resorted to using the auto start and manipulate the vehicle start that way. A vehicle randomly shutting off when attempting to drive put myself and others at risk. I took the vehicle to the dealership and it was diagnosed that my Radio Frequency Hub module would need to be replaced. The part was replaced and programed resulting in the issue being revolved however the dealership failed connect both keys to the new RFH unit. After some reached I saw that the 2022 Jeeps had a recall for the same component: Customer Satisfaction Notification Z23 Radio Frequency Hub Module. unable to upload invoice at this time but can provide via email upon request

Generally, for the entire time we've owned the car, it has ongoing and systemic electronics malfunctions. This ranges from the car slamming on its own brakes while driving to systems not working to the seat shifting on its own while driving to false positives in the NAV system, etc. A lot of the malfunctions are funny, some are dangerous, but the common thread is that in spite of months in repair and countless supposed repairs by dealerships, the problems continue. And, yes, some of these absolutely put safety at risk (slamming on the brakes for no reason, false positives on detecting objects in road, seat moving during vehicle operation, speedometer ceasing to work, etc). Chrysler has confirmed and acknowledged these problems in the form of various settlements in spite of our requests for a buyback, offering us money, but leaving us saddled with the lemon. What I'm complaining here about, however, is that for the second time the vehicle has apparently caught fire in the engine when started from being off. The first time, it was supposedly fixed by replacing a sensor, but it did it again today, stranding my wife and young son in a parking lot. This car is a death trap and will, sooner or later, hurt or kill someone.

This has happened a few times, just will be driving and the collision lights will turn on my dash. Has not caused any serious issues. but i am concerned one day this will alert my Automatic break and cause my car to stop while driving and cause serious harm to me or someone else. I have taken this to the shop and was just told they can not get it to " pop" up on the dash so aren't sure how to take care of it

Electrical System: The dashboard and screen have repeatedly turned off, the windows have become inoperable, and numerous warning lights and messages have appeared, including alerts for night vision, front camera sensor, and service car. Climate Control System: The system blows inconsistent temperatures, ranging from extremely hot to very cold. It also gets stuck in windshield defrost mode regardless of the selected setting. This has caused dangerous fogging of the windows, obstructing my vision while driving. Drivetrain: The vehicle shakes and trembles, both at high speeds and at a complete stop. There is also a distinct abnormal sound coming from the driver's front side. These issues suggest potential problems with the axle, transmission, suspension, or a combination of these components. Potentially the Engine: The vehicle has experienced sudden acceleration issues while shifting gears, which could indicate an engine-related problem. Loss of Vehicle Control: The trembling and shaking, particularly at higher speeds, can cause a loss of control, increasing the risk of an accident. Unexpected Acceleration: The sudden acceleration issues while shifting gears could lead to unintended speeding and collisions. Impaired Visibility: The climate control malfunctions, specifically the extreme temperature fluctuations and persistent fogging of the windows, significantly reduce visibility and make it dangerous to drive, especially in inclement weather. I have been forced to pull over multiple times to clear the windshield due to the severity of the fogging. Distraction and Discomfort: The extreme temperatures blowing from the climate control system are distracting and uncomfortable, which can impair my focus while driving. Car has only been inspected by dealership. No there were no warning messages prior to the car starting to act up.
