My radio touchscreen will do things on its own, it will adjust my heating and cooling, my setting, flip from radio, Bluetooth, usb. Call people and just like freak out. And i have no control over it and it wont stop. I have only had my car since February and it also only has 50,000 miles on it
Car caught on fire while engine was off
While driving the vehicle it shut off and would not start unless the vehicle was jumped. This happened twice in the middle of the highway, extremely dangerous my children were in the vehicle and other vehicles had to swerve to avoid contact with my vehicle. I took the vehicle back to the dealer that i purchased the vehicle from and they could not figure out the issue. My vehicle is currently with another independent dealer, i changed both batteries, i changed the alternator, checked all of the fuses and checked the relay switches and the vehicle still will not start without a jump and it will only run for a day without needing a jump. No warnings, it just happened.
UConnect 8.4 touchscreen just started going crazy like someone was constantly pressing multiple buttons without stopping. Makes it totally unusable. Distracting driver.
Communication screen started to delaminate and causes ghost touching. I can be driving along and the radio plays or changes stations, it has dialed contacts, etc. Without me touching the screen. When it happens it requires special attention such as trying to cancel a call being made or turning off the radio.
The contact owns a 2018 Jeep Grand Cherokee. The contact stated that she noticed a burning odor while operating the heating system. The contact then stated that she noticed smoke coming through the vent. No warning lights were illuminated. The contact stated that she was concerned for her safety. The vehicle was taken to an independent mechanic where no failure could be determined. The dealer nor the manufacturer was not notified of the failure. The failure mileage was approximately 100,000.
8.4” unconnect touch screen radio is bubbling. This bubbling causes the touch screen to select randomly. It will change climate control setting, screen settings, turn the radio on, turn seat heaters on, manipulate the navigation system. This becomes a large distraction while on the road and is extremely dangerous. This is a known issue with these radios in several Jeep/Dodge/Chrysler/Ram models. We have taken the vehicle to the dealer and asked for this safety issue to be addressed. They have responded that we are responsible to fix at our own cost.

When it happens it requires special attention such as trying to cancel a call being made or turning off the radio. Online searches seem to indicate this is a common issue with Jeeps and Chrysler products around the model year 2018. Naturally, the car company is hands off but my research suggested informing the federal safety agency as you may want to monitor how often this happens. Thank you.
The uconnect system has been malfunctioning. The uconnect system has all functions for radio, climate control, system functions, Phone, backup camera, gps, etc. the system started randomly making phone calls, switching radio channels, wanting to connect or disconnect devices, displaying the rear view camera and gps screen jumping around giving misleading directions all occurring while driving. We took the car in to see if it can be fixed. Jeep dealer advised a new system was needs at a cost of $1500. Jeep is unwilling to correct the condition without replacing the unit but there is no guaranty the issue won’t reappear. Most recently there was a software push that will not load due the internal system error. Creating another distraction with a recurring error code popping up due to update failure.
I have a 2018 Jeep Grand Cherokee Overland Edition. The laminate is coming away from the radio screen and it keeps showing an "adjust clock message" and "morse code" like beeping. It is a complete distraction. Due to the laminate coming away from the screen the unit starts overriding the driver choices, like the handsfree features, radio, heated seats, etc. This is a safety issue with the car controlling things the driver should be. It's been going on now for a month.
Control screen is delaminating causing ghost controls and making it impossible to adjust or turn on/off climate controls- AC, heating, dehumidifier… making it UNSAFE to drive. In addition radio stations jump from one to another - a mere distraction in comparison to the climate control problems Please recall !!
The contact owns a 2018 Jeep Grand Cherokee. The contact stated while driving 45 MPH and approaching her residence, the vehicle lost electrical power, causing the power steering and brakes to become inoperable. The messages "Service Stability", "Service Transmission" and other unknown messages were displayed. Additionally, the check engine warning light and other unknown warning lights were illuminated. The contact was able to veer to the side of the road, where she continued driving until the vehicle stopped in front of her residence. The contact stated that the vehicle restarted and operated as needed the following day. The contact stated that the failure reoccurred a week and half later. The vehicle was taken to dealer, where the alternator was replaced; however, the failure reoccurred while returning to her residence. The contact was able to jumpstart the vehicle and drove to her residence; however, the failure reoccurred in front of her residence. The dealer was notified. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 65,524.
The touch screen on the info-tainment head unit is delaminating which is causing the screen to register touches that did not occur. These "ghost" touches are resulting in the head-unit changing settings, starting navigation without prompt, and making phone calls. The un-prompted phone calls has been particularly distracting as there is no means to hang up and has forced me to the side of the road several times to try and end the call. On occasion, the system has made calls to 911 without me prompting it. These incidents have made driving with the head unit operating un-safe
Radio does not work properly. The radio jumps around all setting, and makes calls if cellphone is connected.
Screen de-laminated, causing ghost touching and different radio stations to be selected nonstop, volume to increase/decrease without the ability to manually intervene, called 911 by itself while driving the vehicle.
Screen delamination of the connect screen has started causing severe ghost touching. Making the system useless and distracting. Unable to use handsfree systems, navigation, radio, or access vehicle settings including the jack mode for the air suspension. On my vehicle it has not been diagnosed by the dealer but this is a known and common issue with this system for 2018 and 2019 and fca\stellantis needs to be forced into a recall for this.
There is an electrical failure that causes the blinkers to stop working, shortly after noticing this issue the vehicle will fail to start after travelling to my destination. This has happened more than twice and there are no recalls shown for the "Limited" version of this vehicle. The standard edition seems to have confirmed recalls for the same issues that the Limited version is experiencing. A mechanic has described an electrical short circuit. I encourage looking into the different models of the 2018 Jeep Grand Cherokee in which you'll definitely find the same safety issues described online by many others. These repairs need to be addressed and repaired by the manufacturer. Thank you!
I am the original owner of a 2018 Jeep Grand Cherokee with 45,000 miles on it (it is out of the warranty period). About 9 months ago, I notice a portion of the center screen becoming delaminated. Then about 4 months ago, the screen started to act up - ghost pressing certain areas of the screen, without me touching it (automatically turning up the volume, turning on heated seats (in Florida), changing audio sources, changing the gps, etc.). It's extremely distracting when I drive. Last week, it even dialed 911 on its own while I was driving it. I contacted Jeep Cares and was instructed to take it into a dealer for a diagnostic check. They are charging me $190 for this. Even when they find the screen defective, I'm fearful that I will be charged the $1,600-$2,000 to have it replaced. This is a very known issue among Jeep/Chrysler owner - many forums like this (https://www.jeepgarage.org/threads/display-screen-starting-to-delaminate.224391/) prove it. Even though I am out of warranty, I feel that this should be recalled and covered at no charge (including the diagnostic check) since it's a major safety issue. The screen was defective to begin with - and after driving it for a few year, the defects were finally known. This needs to replaced ASAP before a severe accident takes place.
All features of the radio and heating and cooling system on my vehicle Do not properly work. The heat will switch to air at full blast without touching anything. The radio will switch between channels or stop working. You also cannot touch the screen to toggle. Or just the volume. this is extremely dangerous as it happens out of nowhere as you are driving. It is clear when looking online that this is a common issue. This is extremely dangerous. I have reported this to the dealership but they said they have not seen this issue. This is clearly not the truth since it’s so easy to Google and see numerous reports of the same incident.
Screen delaminating, it is causing havoc on my driving with the screen having a mind of its own!
The unconnect stop working and the radio went black
The UConnect in the vehicle delaminated, which caused a crack on the screen. Due to that, the back up cameras do not work & the controls for most things in the vehicle are unable to be used now because they are all connected via the UConnect.
The UConnect radio has delaminated and is available for inspection. Due to the delamination of the UConnect system it will randomly change channels, replace channels, and will skip around to other parts of the system. This issue does not always occur and is random and unkown when it may happen. When the system does this it is a distraction to the driver and could cause a potential incident. This appears to be a known issue with 2018 Jeep Grand Cherokees and Dodge Ram pick up trucks based on a google search. There are several threads that discuss the issue and the safety concerns it may cause. There were no warnings of the issue. The delamination has been a slow process and was unaware of the issues that it could cause with changing stations and other items randomly.
The contact owns a 2018 Jeep Grand Cherokee. The contact stated while starting the vehicle the PCM warning light illuminated. The dealer was contacted, and the dealer stated that the vehicle was previously serviced under the federal safety agency Campaign Number: 18V332000 (Electrical System, Vehicle Speed Control) and that the contact had to pay out of pocket for all future repairs. The manufacturer was contacted but provided no assistance. The failure mileage was 70,000. The contact stated that the vehicle was serviced at the dealer per the recall but is experiencing issues. A warning light keeps appearing even after the vehicle's powertrain control module was reprogrammed.
The vehicle continues to not start. Replaced both batteries (main & auxiliary) in two days later the vehicle would not start without a jump. Checked the alternator and used a voltage meter to test all fuses. Also was placed on a diagnostic machine nothing detected. The vehicle will run for a couple of days with no problems and then will not start. Took the vehicle in for the recall. The dealership fixed the recall and now the antilock brake sensor light is on and the slippery when wet light is on. I have been told by a mechanic that there has been an TSA stating the TIPM is known to be defective. I have been told the TIPM (fuse box or brain) can cost 600-1000 to replace. The vehicle only has 80000 miles on it. This problem should not be a consumer issue when it has been identified as product defect. Please help.
I have had a problem with the vehicle just shutting down while driving and it seems to have a wiring issue to the oem fuse box which keeps blowing the fuse. I see in 2018 there is a recall on the wiring but when I put my vin in it doesn't show that? I was on the highway and the vehicle shut off while driving and almost got killed with my granddaughter in the back seat when the vehicle behind me swerved into the fast lane and hit a part of the guardrail. I couldn't even put emergency lights on because the power died on every thing
Uconnect System Malfunction/Delamination: EXTREME SAFETY ISSUE: 1. Screen freezes and fails to project image onscreen while backing up. 2. Independent of operator touching screen: --system turns on/off. --increases/decreases volume. --changes stations, and media modes. --navigation frequently freezes during critical intersections. --climate control inaccessible. --randomly dials 911 and other random phone numbers. 3. UConnect fails to turn off even after leaving vehicle. Vehicle is primarily driven by inexperienced 17-yr-old driver. He gets disoriented when back-up camera freezes causing him to stop/park/restart vehicle very possibly in harms way. He has consistently complained about how distracting it is to try to control the system malfunctions while driving. Very often needing to pull over in areas that may not be safe. I have called Jeep Cares, FCA Recall Assistance Center, and visited Dealer Parts Dept and Service Dept. They are aware of but refuse to address the problem in spite of NUMEROUS COMPLAINTS ONLINE until I pay them non-refundable $195 for them to officially diagnose a known problem and activate my case. I have a video taken in early 2021 (before end of warranty) thats illustrates some of the issues, but could only upload a still image below.
the uconnect screen is bubbling and de laminateing and causing the display to randomly change to all different screens from radio to heat to clock to navigation constantly changing cannot work the navigation, climate control, or radio or any he controls
The Uconnect system laminate bubbles and as such, the system has a phantom buttom touch every few seconds. While driving, this results in an audible ding, the navagation no longer is visible, you are unable to use the backup cameras. I have also been in a situation where it turned on the seat and steering wheel heating and I was unable to turn it off. This is a very wide spread issue and is an incredible safety hazard when driving. It effectively makes it not possible to control the electronics of the vehicle while driving. I urge anyone reading this who does not think this is a huge issue to try driving one of these vehicles while this is happening. I used to drive over 20K miles a year with my previous vehicle. This issue started a month after I bought this vehicle from Vroom. As such, I have driven less than 1,200 miles in 18 months. I am incredibly surprised that this has not been recalled yet. I am trying to upload a video of it but it will not let me. This is a MAJOR problem.
