The electrical system per the on-dash guide shows a voltage of 13.8 V or less than the 14.2 V and when it is less than the 14.2 V the car drives choppy, braking causes the car to jolt around even after brake work. The radiator was recently replaced and new hoses were replaced and it still has not been remedied after new brakes and new serpentine belt. The dealer did not clean all remaining radiator fluid that spilled in the bottom of the car, as the radiator had not completely been malfunctioning prior to arrival at dealer. This has probably caused some corrosion due to faulty manufacturing and use of subpar components to where this would become an issue. The air hoses continuously make noise as there is intermittent whirring. The electrical components of the car which I assume are manifested via the voltage regulator cause the adaptive cruise control/ auto stop-start to become 'unavailable' intermittently throughout driving the car. There have been recalls issued for other Jeep Grand Cherokees for the very same issues that my car is experiencing and I want this to be remedied and not at my expense.
2018 Jeep Grand Cherokee electrical complaints
Page 6 of 12: complaints 131 to 160 of 339, newest first, as owners wrote them.
The radio changes channels on its own and dials phone numbers at random.
The UConnect system seems to be changing setting on heating and volume controls as well as many other features. It has caused me to be very distracted while driving. It seems to be a real problem among all of the same systems. Please help!
The contact owns a 2018 Jeep Grand Cherokee. The contact stated while driving at an undisclosed speed, the safety hazard warning light illuminated, and the vehicle was making abnormal sounds. The vehicle was taken to the dealer, and the dealer related the failure to the federal safety agency Campaign Number: 18V332000 (Electrical System, Vehicle Speed Control). The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 7,858.
UConnect 8.4 has delaminated at the top of the screen, making it unsafe as the screen now clicks itself. Sometimes it changes the radio station or changes the time setting, or calls people randomly. The navigation system is obsolete because the screen clicks itself and reroutes destination. It is very distracting. It makes the radio and Sirius XM not usable.
The touchscreen has delaminated causing the radio, navigation, and other features managed through the touchscreen to be unuseable.
Interactive touch display screen delaminating causing ghost touching leading to functional changes in regards to switching from Heat to AC, switching navigation off and changing functions sporadically leading to distraction and difficulty operating car.
The display for the radio, navigation and other components is malfunctioning. The radio switches the station without warning and goes back and forth between FM and XM on its own. The navigation screen or a message stating "Do you want to adjust your clock settings?" pops up on the screen and then disappears. It prevents me from being able to adjust any of the settings or control the radio. The most worrying issue is that if the seat warmers are on, you are unable to turn them down or off, causing the seats to become uncomfortably hot. I have not had the vehicle inspected. There was no warning message or other symptoms before these problems became evident. They first appeared 60 days ago and have progressively increased in frequency.
Laminating screen Unable to access handsfree functions could lead to accident inspected by Sandman's, Shelbyville, IN
For the past month the radio has been changing channels continuously, the volume changes, the seat warmers and heater turn on and off. I researched this and found many others with this problem. It is a safety concern.
What component or system failed or malfunctioned, and is it available for inspection upon request? Front left blinker failed, front right headlight failed, both at the same time. How was your safety or the safety of others put at risk? Both failed and now there is no blinker or headlight to drive safely at night or in inclement weather. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the auto shop confirmed on 1/17/23. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. The failure occurred on 1/14/23, car would not start at all. On 1/15/23 I went back to start it again and it started, tried to drive away and the car shut off on me while driving. The car then began to honk randomly, all the wipers went off, and the lights started flickering. I turned the car off completely and tried ot turn it back on and the car would not start again and also the front left blinker was now completely not working and the front left headlight is completely out. There is a warning on my car for the front left blinker but not for the front right headlight.
October 31, 2022 - Check Engine Light came on. Autozone gave me the P0456 code - Small Leak in Evap System. The check engine light went off a week later. Continued to come on/off for the next 2 months. I was able to finally get an appt on 1/9 and took it into San Diego Jeep Dealership on Camino Del Rio S. They charged $500 for diagnostic even though I had the code already and replaced the Purge Valve & Hose. On 1/14 my car engine would not start at all. On 1/15 my car engine started, I went to drive and within a block my car shut off on me and I coasted to the side of the road while it threw a bunch of different errors including electronic stability warning. I came to a stop and then all of my windshield wipers randomly started going off, my horn randomly started going off, and the lights in my car started flashing. I pressed the push start button to try to turn it all off. I then got the error meesage that my front left headlight was out, it now is, alos my left blinker now doesn't work properly. I tried to start the car again, no luck. I called a tow truck, the tow truck guy was able to get my engine to start. I explained that my car shut off and asked him to follow me for a little while. I got 2 blocks and came to an stop sign where I idled and my car engine shut off on me again. I had my car towed back to the dealership that did the work. On 1/16 they told me it would be $700 for an electrical diagnostic. I did not have any major problems or warnings before taking it to the dealership.
One year after I purchased my Jeep the screen starting delaminating. This created “phantoms touching” It started out small but eventually became to where the Jeep was not fuctional. Including not being able to adjust temperature to defrost or defog my windshield. This is an extreme safety hazard with no work around. The screen overrides anything I do with the physical buttons below it. The screen turns back on even when I try to turn it off. This is especially a problem because I live in the Midwest with plenty of ice & snow. It’s incredible that I have not caused an accident yet. I have made plenty of phone calls to Jeep who refuse to recall the screen even though they have admitted it is a known problem with the screen itself. Not only is it a safety issue but I cannot access several of the main functions.
My Jeep started skipping through screens on the display randomly in August 2022, but since has increasingly doing it nearly everyday now. There is a visible big “drip” look on the screen in the top right corner. The screen now will call contacts on my phone and has also activated the SOS calls 4-5 times. I have to drive without connecting my phone to stop the inadvertent calls but the screens continue to flip through on its own. This is very frustrating and distracting while driving and the obnoxious ding it makes with each switch. The seat warmers flipping on constantly is also very distracting when the high setting is hot enough to make me hop to prevent injury and pain.
For my 2018 Jeep Grand Cherokee: the UConnect touchscreen which controls everything from the parking assist functions to navigation to climate is delaminating. As a result of the delaminating screen, the screen will malfunction while driving the vehicle causing it 1) become permanently "stuck" on the rear back up camera/parking assist mode or 2) override driver selections and prompt the driver to select/deselect other functions unrelated to driving causing dangerous distractions and impacting our ability to use the car and system safely.
The infotainment screen started acting crazy and makes it difficult or impossible to operate the vehicle when misbehaving. The screen will lock up and not respond to any touch control. Powering the vehicle off and on at a traffic light does not fix the issue. Of course, this means I cannot operate the HVAC, navigation nor any other controls requiring the touch screen. The system will also switch on its own into different modes and selections... radio, seat and steering wheel heaters, volume, etc. The problem is frequent and persistent. The screen has also delaminated and is becoming harder to see/read. The malfunctioning of the screen is a big driver distraction taking away from attention on driving. Not being able to turn off or on the seat warmers nor the HVAC when malfunctioning causes discomfort and distraction. I have reached out to Jeep customer care but have not made contact with them yet.
Car radio gets stuck on screen that says "do you want to adjust the clock" . You cannot get into any of the apps that change the braking system or change the heat settings (like defrost) It just jumps back to do you want to adjust the clock. Sometimes the screen just goes off completely. Looks like the screen is delaminating. You can see the bubble underneath.
This concerns the malfunction of 2018 Jeep Grand Cherokee Uconnect 4C NAV with 8.4-Inch Display UAV Radio. The dealer removed the radio and inspected the problem. The touch screen bubbled/delaminated and the adhesive must of warmed up from the radio use and dripped down to the bottom of the radio affecting other components. The radio will change stations on it's own,navigation won't work. If i have my cell phone on it will make random calls and it will activate the SOS call. That happened 3 times and 2 times i was driving on the highway. That did take my attention away from driving. Now i have to make sure my phone is off when driving. I didn't renew my Uconnect subscription so i didn't get in trouble for that. My chrysler factory warranty denied a replacement. They told me the dealer said something about it was an outside influence (a sticky liquid inside) caused the radio problem that made the radio act that way so it's not covered. Giving you an approximate date is hard to do. It happens a lot. The date i put is when it started to really act up
The Uconnect system has been delaminating for a while now. As such, there is "ghost pressing" of buttons on the screen. This, while driving, renders many important components of the vehicle unusable. There is a loud ding, then the reverse cameras go out if using them. Navigation ceases to work. Heating, cooling are also affected. I had not given much thought to how bad of a safety hazard this was until it started up on a 3 hour drive. The distractions of having most electric components go haywire while on the road is quite incredible. This is a well known issue so I am dumbfounded that it has not been recalled. I have had 3 quotes on the vehicle and all say that the unit needs to be replaced. Uconnect will not assist and Jeep wants full price for a fix. As such, I have drove my vehicle 1-2K in 15+ months as it is completely unsafe.
The infotainment system screen keeps changing and asking if I want to reset the clock. It also turns on the heated seat and steering wheel heat and blower motor requiring constant attention to the screen to try to turn things off and causing constant distraction from driving.
Infotainment screen has slowly been delaminating. Today, the screen began receiving phantom commands. I do not touch the screen, but the screen acts as though I am constantly touching it in random places. The radio, defrost, maps, backup camera, etc. turn on and off. It has made my car unsafe to drive because I can't keep my windshield defrosted, I can't use the navigation feature, I can't properly use the rear camera in reverse, and there is persistent beeping from the screen mistakenly sensing that I am touching it.
The UConnect screen is delaminating which is causing the touchscreen to malfunction. This is causing the navigation system, radio, seating controls, and climate control to be inoperable for spans of time. I have already had several occasions where this has caused unsafe driving conditions.
While car is driving, the infotainment system which controls heating/air conditioning, NAV, radio, etc. will start to flash, make noises on its own, play the radio and the stations switch on their own. It is extremely dangerous and distracting while trying to drive the car. The only way to stop is to turn it off but then you have no access to a navigation system which presents its own dangers. Without proper heating in the winter months or cooling in the summer months, the car can be dangerously cold or dangerously heated, especially dangerous when driving around young children or my elderly parents. When I contacted the dealer about it, they reported they have heard of this happening, that there is no recall despite the inherent dangers and that it would cost over one thousand to repair. It has not been inspected by any manufacturer, police, insurance rep or others as it has only been occuring for a couple months and I was hoping if I reset the system, it would stop. There have been no warning signals that this is occuring. When I decided to do an internet search, I found that thousands of 2018 Jeep Grand Cherokees are having this issue, that it's been widely reported to the federal safety agency and that Jeep has not issued a recall, despite the dangerous driving of a vehicle such as this.
Touchscreen display bubbling, delamination, malfunctioning during use, including during back up camera usage/display, navigation display, climate control malfunction. Touchscreen malfunction including functions turning on and off by themselves, system has life of its own. Display continues to show back up camera display even when driving forward commences (see photo). Safety issues/Symptoms include radio changing volumes to extreme levels my itself during driving, back up camera while in use disappearing and screen going blue, navigation system while in use changing to other functions without user input.
there's is a problem with the Touch Screen where a message keeps popping up and after a period of time this causes the Touch Screen to be unusable (can't use Navigation, Radio, Hands Free Calling etc.). after doing research online it appears this is a known problem and is the result of a flaw in the Manufacturer's (LG) process (delamination of adhesive between Screen and Digitial Touch Component). As a side note, I mentioned this when I brought my Jeep into the Dealership for service and they confirmed they were aware of it (their solution is to charge me $2,145 to replace the Radio...the Radio isn't the problem, it's the Touch Screen that has the issue).
The infotainment system (radio) has been delaminating and has ghost touches. It stops to work at any moment causing a safety issue. Reverse camera stops working and the ghost touches are very distracting while driving.
The control screen of my jeep is 'delaminating'. This is apparently quite a known issue to the manufacturer, however they wont do anything to address it. When the screen starts reacting to phantom touches, not only can I not control anything in the car, it is very distracting to the driver to put it mildly. I have also read that as the glue melts, it leaks onto the wiring of all the components under the screen including the AC, all the parking sensor and traction control off controls.
The 8.4 touch screen is delaminating causing the whole screen area to randomly turn things on and off on its own. Changing certain settings while driving. Safety settings are being affected as well as the touch screen controls almost everything. The defective touch screen is causing a distraction while driving. Contacted jeep they are aware of the issues but no one wants to take responsibility to fix it.
Touch screen is delaminating and has ghost touch causing random unintentional functions to be selected and others to be obscured. Heated seats come on and won't turn off. Phone calls are made on their own. Repeated screen messages from ghost touch selections obstruct use of screen for intended purposes which include most vehicle controls. It presents a serious driving distraction. I consider this a safety issue. It is a known defective part for which Jeep has a replacement but won't offer the replacement at no cost out of warranty. Cost is approximately $1,000.
The contact owned a 2018 Jeep Cherokee. The contact stated while at a complete stop at the traffic light, with the START/STOP mode engaged, the vehicle accelerated unintendedly and crashed into the rear of another vehicle. There were no warning lights illuminated. The air bags deployed. The contact stated that the forward collision automatic braking system failed to engage. The contact sustained back pain. The contact also sustained trauma and had been seeking assistance from a therapist. The occupant of the other vehicle did not sustain injuries. A police report was filed. The vehicle was towed to a tow lot where it was totaled. The contacted related the failure to the federal safety agency Campaign Number: 22V426000 (Service Brakes, Hydraulic). The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 34,000.
