| Mar 2024 | SEATS | I was driving down the interstate and heard a very loud pop and got smacked in the back of the head. Later inspection seems that plastic ears connected to the foam portion of my headrest broke off both sides of a horizontal pin they were connected to | Crash: No Fire: No | Unknown |
| Mar 2024 | UNKNOWN OR OTHER | The radio touch screen is delaminating causing the radio and its other features to change without warning creating a distraction for the driver. Navagation destination changes loosing route information causing the driver to slow down or stop to try to return to the selected route information. Phone calls are disconnected and the phone then indiscriminately dials a new number from the contact list. You hang up that call and the screen redials the number. This basically negates the functionality of the hands-free feature. This creates serious safety issues when the unit overrides driver choices, as it is distracting because it requires the driver to correct the changes brought on by the malfunctioning screen. | Crash: No Fire: No | Unknown |
| Mar 2024 | UNKNOWN OR OTHER | Touch screen started randomly changing radio stations, map kept popping up and it would randomly change inputs such as AM, FM, Sirius, etc..

| Jan 2024 | ENGINE | I have a 2018 Jeep grand cherokee and one day it just didn't start. I had it towed to the jeep dealership and was told it was the starter. Once the job was done they service rwp said they will run a complete diagnostics on the jeep and get back to me. I got a call a few a days later saying the jeep had a blown head gasket, a leaking water pump and the coolant was leaking as well. They said the engine was a complete loss and to replace it and labor cost would be 14k. This jeep only has 40k miles on it and those are really soft miles, my wife literally works 5 minutes from our home and it's here daily driver. How is this possible, it's just plain ridiculous. Reaching out to jeep and got no help whatsoever. NEVER BUY A JEEP! | Crash: No Fire: No | Unknown |

| Jan 2024 | UNKNOWN OR OTHER | Driving and the display screen kept switching uncontrollable and caused a safety issue while I was driving and was not in a familiar place, and was trying to use the screen for navigation directions. Concern as it was switching screens/adjusting the heat controls while I was driving. Research indicates my screen has become delaminated and a known issue with this car. Concern that while I drive this continues and may be a safety risk. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | BUBBLE IN SCREEN SYSTEM ACTING FUNKY I JUST PURCHACED THE JGC ON 01/16/2024 THE NEXT DAY THE SCREEN GOES NUTS CALLED THE DEALERSHIP AND THEY ARE GHOSTING ME VERY UNHAPPY FIRST TIME JEEP OWNER | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | Delamination of radio is causing the radio to change radio channels, not be able to use the handless phone option or adjust heated seats. The constant beeping when the radio is constantly and randomly changing channels is a safety hazard. FCA is aware of the issue and has not issued a recall and is denying repairs for the consumers. | Crash: No Fire: No | Unknown |
| Jan 2024 | ELECTRICAL SYSTEM | 1. My instrument panel screen is completely non-functional due to delaminating / experiencing delamination. It is available for inspection upon request. 2. I can no longer manage the air flow in order to properly defog my windows. I was driving on a highway, the windows were fogging up, and I could not defog my windows. It was incredibly dangerous to myself and the other cars around me as I could not see them. I can also no longer make phone calls through the car as it would randomly hang up or mute the calls. 3. It is a constant problem, and has been rendered permanently disabled. 4. It has been inspected and confirmed by others, yes. 5. The screen started to bubble in one corner (now half of the screen has bubbled), and random places on the screen were being "ghost pressed" causing the instrument panel to behave sporadically and trigger all sorts of random functions. This starting happening about 4 years after purchasing it brand new from the Ramsey, NJ Jeep dealership and has progressively gotten much worse to the point of being completely unusable. Every time while I am driving it performs random actions which are incredibly distracting. Changing the radio stations, skipping songs, making random calls, cancelling / or modifying my GPS directions. It is completely possessed. At this point I leave it off most of the time, but do need to use it for certain features, but it's highly distracting and unsafe at this point. | Crash: No Fire: No | Unknown |
| Jan 2024 | SERVICE BRAKES, HYDRAULIC | The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while the vehicle was parked and turned off, the brake light remained illuminated. The contact stated the vehicle was repaired under NHTSA Campaign Number: 22V426000 (Service Brakes, Hydraulic) however, the failure reoccurred. The contact stated that the recall repair was completed in May of 2023 and the failure reoccurred immediately after the recall repair was completed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was unknown. | Crash: No Fire: No | Unknown |
| Jan 2024 | SUSPENSION,BACK OVER PREVENTION | 1.At 63263 miles ADAS front Parking sensor and at 96000 miles Active park assist modules are failing with a pop up message asking for a service. The parts are working intermly but, I believe it could potentially mislead the driver when parking using Active Park assist and can cause and injury or damage if the safety system fails. It was inspected by a dealer before but exact diagonisis was not provided. 2. Air Suspension system warning came up at around 96000 miles. I immediatly took it to a dealer who charged 1800+ dollars to inspect and replaced a valve block mentioning C1556 code and said the poblem was sorted. I checked my car and the system warning still exists. They took the car immediatly and kept for 4 days and mentioned the air compressor in air suspension could be weak and over heating causing it to fail. They mentioned there were no leaks on any air bags of the suspension and quoted a 3400$ additional cost of repair. I believe the inital diagonisis was incorrect or not up to the mark (the part is available for inspection) from the dearlership as there were no clear indication of what was the root cause. This suspension failure could cause the ride height to fail any time and can cause imbalance while stopping the vehicle at higher speeds as it has an Aero mode. The air ride system is working intermily depending on the climatic conditions the components are malfunctioning which has to be addressed by the FCA group. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | I purchased a 2018 Jeep Grand Cherokee. The second I left the lot, the screen started flashing the Clock Settings screen. I researched this and it states that it's a known issue because the screen delaminates. I purchased a warranty and the company will not cover it. This is a SAFETY HAZARD. From hours of research, this issue has been known and Jeep needs to do a recall on this. If someone gets hurt pertaining to the disfunction of the screen and it's options, there will be a lawsuit and I don't think Jeep wants to deal with that. I'm trying to upload a video of what it does, but for some reason this website isn't letting me upload anything. | Crash: No Fire: No | Unknown |
