2018 Jeep Grand Cherokee Electrical System Problems

had a recall done in February and 3 weeks later the car would not start randomly no warning lights illuminated on the dash prior to being shut off and once it would start it threw 3 codes for p0850, u0100, and U1267 all related to the parts replaced in February for the recall for the 2nd time now regarding the same parts. and trying to get a reinspection done for the recall bc the parts seem to have failed and its been a living nightmare. and unsure why no warning lights were illuminated prior to the car not starting randomly

Upon vehicle start-up, the Uconnect screen will freeze up. Placing the vehicle into reverse, the back-up camera is not shown. During the issue, the screen could be frozen/not responsive, or a blue screen. This concern has been an ongoing issue for some time now. It seems to be getting more frequent recently.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the “Service air Suspension” warning light was illuminated. In addition, the contact stated that the headlights independently turn on and off, the doors independently locked and unlocked, and the radio independently changes stations. In addition, the contact stated that the failure caused the headlights to burn out prematurely. The vehicle was taken to the dealer; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact was later informed that there was moisture in the wires. The contact was informed that the moisture had been cleaned from the wires. The contact was informed that the vehicle was repaired. The contact disagreed with the diagnostic test and the repair. The contact stated that the failure was a known failure with the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000. The VIN was unavailable.

I have noticed the upper edge on my radio screen appears to the bubbling or separating from itself. It has recently become worse and causes "touches" on the screen. It makes calls and ends calls, switches the screen on and off, changes heating settings, disconnects devices, changes or cancels navigation. It makes it very difficult to drive as I cannot turn the screen off.

The car keeps saying the turn signals are out when they all function properly. The car is equipped with the LED factory headlight systems. When it thinks the bulb is out it makes everything flash or turn off so other drivers can’t see your signal. Several other users are also reporting issues online. Dealer says the only way to fix is an entirely new head light assembly at $1300 since the turn signal bulbs are built into the headlight and should be a lifetime part.

A vehicle that is able to start and shift out of park without depressing the brake pedal can result in unintended vehicle movement which can cause a vehicle crash without prior warning and/or injury to others outside the vehicle. There has been a recall out for over an year yet no available solution.

I have videos, but my cars electrical system keeps glitching, It will turn my heated seats on to the pint they burn me, it connects to my phone and will randomly call anyone in my contacts, it changes radio stations, messes with my automatic start, took my traction control off and does this on a regular basis. I had this system fixed in March of 2023 just after I bought the car but it’s already doing it again. It also will randomly just cut off when I’m driving and then will be fine very randomly. - I will have to send you the videos I took it says they are too large to upload here

The 2018 Jeep Grand Cheeroke Uconnect/Radio screen delaminates and causes the unit to make all kinds of error calls, GPS location changes and disabling events, without being touched. This is a serious safety concern and that Jeep or Stellantis should voluntarily recall these units for replacement. The driver's attention gets constantly divided to take care of these extra things while driving.

The radio in this vehicle has a widespread issue where the screen delaminates and starts ghost touching . Options are randomly selected , people are randomly called , emergency services are attempted to be contacted. Basically anything that the radio controls in the car could be changed or activated . This is extremely distracting and could cause someone to take their focus off the road and cause an accident. The radio controls heater, navigation, seat heaters, phone calls , steering wheel heaters , and many other functions in the car some of which cannot be changed without the malfunctioning radio being on. Fixing this issue is somewhere in the range of $1300 at the dealership. I feel like this is and important safety issue that causes a lot of distraction when driving the vehicle and is really difficult to work around or avoid as the random screen touches are not predictable and seem to happen at random times.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while the vehicle was parked, the back-over prevention APP independently uninstalled. In addition, the contact stated that the vehicle had not been started in eight days. In addition, the stabili-trak warning light had illuminated a month prior, which was the initial failure. The vehicle was taken to the dealer, where it was diagnosed with a failed transfer case. The contact was informed that the transfer case needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle was taken to two additional dealers for confirmation; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the failure might be related to the UCONNECT connection. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 88,727.

Urgent Safety Concern Regarding Defective Uconnect Radio System Shortly after purchasing my vehicle from Bertera in Westfield, Massachusetts, I began experiencing issues with the radio and related components—namely, erratic or "ghost" activity. I returned the vehicle to the dealership on multiple occasions; however, because the issue failed to replicate while in their possession, they were unable to offer any resolution. The problem persisted intermittently, but escalated significantly during a visit to Logan Airport. While curbside, the vehicle began behaving erratically: the exterior lights flashed, doors locked unexpectedly, heated seats activated, windows became unresponsive, and the vehicle could not be exited—even when approached by a security officer. After powering down and waiting for several minutes (with permission from security, as we exceeded our time limit), the system reset.Despite this dangerous scenario, the dealership again reported they could not reproduce the issue and offered no corrective action. On June 11, in preparation for a trip to Boston, I brought the vehicle to Bedard Brothers in Cheshire, Massachusetts—a certified Jeep dealership. Their technician determined the radio screen was delaminated and causing unintended inputs. They informed me that since my warranty had expired, the repair would cost more than $1,400. On [XXX], during travel to Massachusetts General Hospital, the malfunction occurred again: the heated seats engaged and would not turn off (despite temperatures nearing 90°F), the radio volume spiked uncontrollably, and the prior array of electronic malfunctions returned. Fortunately, I was able to attend the appointment and make it home safely. I have contacted Stellantis, Uconnect, and the Massachusetts Attorney General’s Office. While Stellantis expressed sympathy, they stated they could not offer assistance. My research has revealed multiple similar complaints from other vehicle owners. Any help greatly appreciated.

CAM shaft and yes it is available to be looked at. The vehicle was misdiagnosed multiple times and sent back home with the same error code while fixing other items that were not the root cause of the issue. The engine light was on with the misfire code when I brought it in and was repeatedly sent home and within 20 miles the same code returned.

I purchased a 2018 Jeep Grand Cherokee on [XXX] unaware that the vehicle was subject to a federal safety recall and stop-sale order. The recall (NHTSA 24V-838 / Manufacturer 94B) was issued on November 7, 2024, for a defect in the ABS control module that may disable the Anti-lock Braking System (ABS), Electronic Stability Control (ESC), and cause unintended vehicle movement even while stationary. A stop-sale order (VIR 2024-11-14) was issued by Stellantis on November 14, 2024, prohibiting the sale or delivery of affected vehicles until repaired. Despite this, the dealership sold me the vehicle while the recall was still open and unrepaired. In the months following my purchase, I began experiencing issues with the Electronic Throttle Control (ETC). On June 15, 2025, I paid $770 out-of-pocket for ETC sensor repairs after a loss of throttle response. The vehicle has not yet been inspected by the manufacturer, but this defect may be linked to the broader electronic issues cited in the recall. No warning lights appeared in advance. I have been driving this vehicle daily without knowing it could malfunction in a way that puts myself and others at risk. I only learned of the recall on June 22, 2025, when I searched the VIN through NHTSA’s database. This has caused emotional distress, financial harm, and a complete loss of trust in the vehicle’s safety. I am seeking appropriate accountability for the illegal sale of this recalled vehicle and want to ensure others are not put in similar danger.

Uconnect 8.4" infotainment screen is delaminating. This causes the touch screen to randomly press buttons during driving. This can make calls to contacts, or emergency numbers during driving. This can change settings at random during driving like seating heat, radio stations, other vehicles settings such as drive assistant software, turning on and off, blind spot notifications, lane assist, etc. Very distracting for a driver to continue to try and drive while focusing on what just happened or what was just changed. If your phone is connected to the device, it can call 911, or other contacts change volume setting, get stuck to where you can't change them. gain very distract and a safety concern. It is a well know issue with this model. This issue is no longer being fixed by service center or dealer without a 1500-2500$ service fee. This seem like a manufacturing defect and major safety concern while driving.

The 2018 grand Cherokee has issues with mother board and electrical ghosts. 1st it was headlights and dome lights. they would flicker. i had to change the front lights 2x in a year. i thought this was odd. never did this with any car before. then I was driving home from work during rush hour and it started to rain. started the wipers front and back. the back wiper started and went halfway and got stuck. what happen? the front wipers went on for several revolutions (say 10-20 ) then stopped. started again. then stopped again. the rain intensity grew. Now the -wipers would only work when turned in opposite direction (the manual 1 pass move). this happened as i was trying to get home and stuck bumper to bumper on [XXX] . on this dangerous highway in middle of now a torrential downpour the front wipers now decided it wouldn't work AT ALL. i couldn't see anything and veered off to the shoulder thank god - waiting for rain to stop and then safely proceeded home. the next day the wipers worked. no check engine or anything. this goes on for a week or so with no issue. then out of nowhere the driver seat decides it has a mind of its own and pushes me all the way to the steering column. it wouldn't return when pushing the back button. i had to drive like that for my trip and then it magically went back upon restart. i take to dealer. pump motors bad on front and back. i say not sure your correct and explain. motor changed on front. not fixed. ok we think its the BCM. changed not fixed. finally the PDM was changed and wow it worked. 2 weeks at dealer and this shows that this issue with the control module is certainly risking peoples safety. i hope Jeep does the right thing and prevents a serious catastrophic event. read on the jeep electric issues and my vehicle had a previous "corrected" recall for Electrical Cruise Control. I dont think the fireware updates or software changes fixed all the bugs. be safe out there jeep INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the expressway, traffic stopped and on the dashboard it said shift to park and the jeep completely turned off. I was in the middle of the expressway so it was scary, I’m glad we were stopped since it was rush hour. The truck turned on right away. I took it to the dealer a couple of days later and they didn’t find the issue. I’m still nervous driving my truck because I’m scared it might happen again

UConnect screen delamination is causing "ghost touching" in system. Climate control, phone, music, vehicle controls - including air suspension settings, are all impacted depending on particular event. Some are just annoyance, some are safety concerns. Air suspension height adjustments and off road settings can be controlled in the UConnect screens. THE ONLY way to lock the air suspension for towing or jacking (tire repair, oil change, etc.) is through the UConnect screens. There are 1,000's of complaints about this system issue on Jeep forums, and I was surprised at the lack of NHTSA complaints when I logged in to see the status. I have video's of the system ghosting on several different screens on different dates if you'd like to have them please provide a link to upload or an email to send them too.

The main screen in the vehicle delaminated and caused quite a number of issues. Heated seats would randomly turn on and off and the temp on gbe seats would not go down, phone would call people over and over including 911, compartment heat would randomly turn on the highest setting and would not turn down, goo like substance came out of screen into the storage compartment below the screen, getting all over items stored. The radio would constantly change stations. All the issues became true safety hazards. I called their 800# and was referred to a dealer who charged me over $1000 with no remorse from Jeep. I am a 25 year owner of jeeps and not too pleased with the lack of response from Jeep. My next car will not be a Jeep!
