|---|---|---|---|---|
| Feb 2026 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | While driving this vehicle under normal conditions, the engine developed abnormal ticking/knocking noises, loss of power, and misfire symptoms that progressively worsened. The vehicle was frequently used to transport children. Due to the nature of the failure and unpredictability of progression, continued operation posed a serious safety risk. An authorized dealer later confirmed that the engine suffered a catastrophic internal valvetrain failure involving collapsed lifters/rocker arms and severely damaged camshafts. The dealer technician explicitly stated this failure mode is “typical” for this engine design and documented progressive internal damage affecting both cylinder banks, not an isolated component. This failure mode is not sudden; it develops gradually over tens of thousands of miles and can lead to sudden engine power loss, stalling, or seizure without warning. A loss of propulsion at highway speed, during lane changes, intersections, or while transporting children creates a clear risk of crash, injury, or worse. There was no evidence of driver abuse, lack of maintenance, lubrication failure, or misuse. The dealer confirmed oil condition and service history were appropriate. The defect appears to be internal, latent, and manufacturing-related, consistent with numerous consumer complaints, technical service bulletins, and ongoing litigation involving this engine family. Had the vehicle continued to be driven, the failure could have escalated to: •Sudden loss of engine power at speed •Inability to accelerate to avoid hazards •Engine seizure causing loss of steering assist •Increased crash risk with child passengers onboard The vehicle was removed from service due to safety concerns. This defect is repeatable, predictable, and well-documented, yet not subject to recall at this time. I am reporting this to support investigation into a systemic engine defect that presents a serious safety risk to drivers and passengers. | Crash: No Fire: No | Unknown |
| Feb 2026 | ENGINE | Warped cylinder head without engine overheating. Cylinder 4 misfire. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE | The check engine light keeps coming on. The Jeep repair shop says that it has to do with the flap on the gas tank where you put the gas in. Hence, the repair light keeps coming on so you never know if its real and needs to be addressed or if its the gas tank issue again | Crash: No Fire: No | Unknown |
| Jan 2026 | SERVICE BRAKES, HYDRAULIC | The contact owns a 2018 Jeep Grand Cherokee. The contact received notification of NHTSA Campaign Number: 24V838000 (SERVICE BRAKES, HYDRAULIC); however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was not available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated that while driving at an undisclosed speed, the vehicle stalled, with the message "Electronic Stability Control" displayed. The cause of the failure was not yet determined. The failure mileage was 88,000. | Crash: No Fire: No | 88,000 |
| Jan 2026 | STRUCTURE,UNKNOWN OR OTHER | 1-Rear driver-side Power Lift-gate actuator ball bolt snapped right off while rear gate is open. 2- It came right down on my head and caused severe bump and bleeding from a 250 pound rear door. I am 6ft 1 in, but if it is someone small it can cause sever injuries and possible death from the heavy door coming down on the person. 3-problem was looked at by my mechanic and they cannot fix issue as bolt broke off inside the thread area and no room to remove such bolt. They recommended I take it to a body shop to cut the area out in order to get the broken broke removed. 4-unknown 5- There was no signs of any failures at all. | Crash: No Fire: No Injuries: 1 | Unknown |
| Jan 2026 | POWER TRAIN | I Purchased my my vehicle from a dealer approximately two and a half months ago. While driving the transmission of the vehicle gave out. The car rpm shot up to seven thousand and only goes 30 mph. My safety was in jeopardy because the vehicle lowed down rapidly and I had to maneuver to the side of the road in order not to be struck from the rear. I had taken it to get inspected by AAMCO and was informed that the transmission failed. | Crash: No Fire: No | 94,523 |
| Dec 2025 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Dec 2025 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING | 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. | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN | I own a 2018 Jeep Grand Cherokee Overland. On December 5, 2025, the vehicle received a transmission fluid exchange service at a Jeep dealership. Prior to this service, the transmission operated normally with no hesitation, harsh shifts, or warning lights. Within a few days after the service, I began noticing delayed engagement and hesitation during shifts. On December 14, 2025, while driving at highway speed, the transmission suddenly shifted harshly with a rapid increase in engine RPM followed by a hard engagement. Later the same day, when stopped at a traffic light, the vehicle hesitated to move forward, revved abnormally, then engaged abruptly. A check engine light illuminated at that time. The vehicle behavior was unpredictable and created a safety concern while driving in traffic, particularly during acceleration from a stop and at highway speeds. The vehicle was driven directly to the servicing dealership and is currently available for inspection. The issue began only after the transmission service was performed. The transmission had no prior symptoms before the service. Warning indicators: Check engine light illuminated on December 14, 2025 after the transmission exhibited harsh shifting and hesitation. Inspection status: The vehicle is currently at the dealership that performed the transmission service for diagnosis. | Crash: No Fire: No | Unknown |
| Dec 2025 | EQUIPMENT | The contact owns a 2018 Jeep Grand Cherokee. The contact stated that the infotainment screen was significantly delaminated, causing unintended screen activation, preventing the driver from activating some vehicle safety functions as needed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was notified of the failure and advised the contact to purchase a new screen because the vehicle was out of warranty. The failure mileage was approximately 80,000. | Crash: No Fire: No | 80,000 |
| Dec 2025 | UNKNOWN OR OTHER | Transmission line has worn a hole from the location it sits under the jeep. The metal hose now has a flat spot. This is because its rubbing on the metal plate below it. I attached photos. I do have a video of what we are seeing and how it’s happening. Yes, it was taken to a dealership for proper diagnosis. Part is unavailable, because of a common issue. No dealership’s are willing to sell the part. It just stated leaking drives fine for now. | Crash: No Fire: No | Unknown |
| Dec 2025 | SEAT BELTS | 8/2023 one rear seat belt would no longer retract. The problem was reproduced by the service center and they replaced the rear seat belt. 10/2025 the same rear seat belt would no longer retract and 11/2025 the other rear seat belt would no longer retract. Brought into Jeep dealer and they verified there are no obstructions affecting the seat belt and they are no operating as intended. They replaced both rear seat belts in 12/2025. | Crash: No Fire: No | Unknown |
| Dec 2025 | ENGINE | I purchased my Jeep in 2023 and have consistently stayed up to date on all required maintenance. I had no issues with the vehicle until recently, when the check engine light and the start/stop warning appeared out of nowhere. After inspection, the mechanic determined that the entire engine needs to be replaced due to severe coolant leakage. My vehicle has now been in the repair shop for over three months because the engine is on national backorder. I contacted the dealership, but they dismissed my concerns and told me that once the car is purchased, it’s no longer their responsibility. I then reached out to the manufacturer requesting a goodwill resolution, given the unreasonable repair delay and the national backorder of such a critical component. Lemon law mileage limits do not apply to goodwill assistance, trade-in support, or corporate escalations. Despite this, the manufacturer has refused to provide any explanation or documentation for why they cannot assist and it has been three months with no progress. There were no warnings or indicators that something was failing internally, and my mechanic confirmed there was absolutely nothing I could have done to prevent this. I’ve also seen numerous reports of this same issue affecting my specific make and model. Stellantis needs to take accountability. It is completely unfair that I am left without reliable transportation for months over an issue that was entirely out of my control. | Crash: No Fire: No | Unknown |
| Nov 2025 | SERVICE BRAKES, HYDRAULIC | The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the service electronic control warning light, the check engine, and the traction control warning lights illuminated. The contact stated that while driving at night and looking in the rear-view mirror, the brake lights remained activated. The contact stated that the brake lights eventually deactivated. The contact stated that the brake light remained on after the vehicle was turned off. The vehicle was taken to the dealer, and the contact was informed that the failures were related to an unrepaired recall. The contact stated that the vehicle was not officially diagnosed. The contact received notification of NHTSA Campaign Number: 24V838000 (Service Brakes, Hydraulic); however, parts for the recall repair were not available. The manufacturer was made aware of the failure several times. The contact was informed that the parts would be available in mid-November 2025. The failure mileage was approximately 55,000. | Crash: No Fire: No | 55,000 |
| Nov 2025 | POWER TRAIN,VEHICLE SPEED CONTROL,SERVICE BRAKES | My brake light light up, check engine light comes on and my Stability Control system does not work. My car won't electric start as the check engine light is illuminated. I took the vehicle to the dealership and they could not help me as there is no fix in place. | Crash: No Fire: No | Unknown |
| Nov 2025 | SERVICE BRAKES, HYDRAULIC | The contact owns a 2018 Jeep Grand Cherokee. The contact received notification of NHTSA Campaign Number: 24V838000 (Service Brakes, Hydraulic). The ABS, 4WD, and traction control warning lights were illuminated. The contact was employed by an independent mechanic, where the codes were reset, but the codes returned after driving the vehicle for five minutes. The local dealer was contacted and confirmed that the repair was not available. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 125,000. | Crash: No Fire: No | 125,000 |
| Nov 2025 | SEATS | While driving on I-95 on 11/14/25, the passenger headrest suddenly and unexpectedly exploded forward with great force while I was sitting in the seat. We were not in an accident or collision. The headrest is now push so far forward that it pushes my face down toward my chest. We cannot reset the head rest to its original position and there is some broken plastic inside the headrest mechanism. A warranty extension has been issued for this known problem with 2014-2018 Jeep Grand Cherokee vehicles. When I called my dealership, I was told that my vehicle model was NOT included in this warranty extension. | Crash: No Fire: No | Unknown |
| Nov 2025 | EXTERIOR LIGHTING | This applies to ALL vehicles not just this one. The bulbs should be designed and able to be changed in the lot of a store not only by a dealer. I will be forwarding this to my rep and the White House. This BS has been going on for decades and this department has allowed this extreme safety concern to continue. Lights can burn out anywhere and anytime and to make this dealer maintenance is BS since they all have backlogs, limited hours and limited qualified workers. | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | Recall as known for 2018 Jeep Grand Cherokee Limited (Service Electronic Stability Control) that is not fixed and no fix in sight. Unsafe to drive. Can’t get a Maine state inspection sticker. Can’t sell. Many electronic codes show on dash. Rear lights stay on and will just go on automatically anytime and when using key fob to lock car. Dealership can’t fix. Manufacturer doesn’t know when there will be a fix. No answers. | Crash: No Fire: No | Unknown |
| Nov 2025 | UNKNOWN OR OTHER | Multiple times now, the rear view camera stays on while driving and there's no way to get it to turn off. Hitting the x in the corner of the screen does nothing, the power button nor the screen off button work, and I cant access anything on the screen. While driving, theres a constant view of the road behind me and it's incredibly distracting. This appears to line up with Recall 20V-191, although my specific car isnt included in that but im absolutely experiencing the same things. No warning messages or anything indicating an issue before it happens - it seems completely random. ive tried soft reset and many button press sequences ive found on forums but the only thing thats ever worked is leaving the car off for 20+ minutes so it resets. This has happened on at least 4 different occasions, I have videos of 3 of them. | Crash: No Fire: No | Unknown |
| Nov 2025 | ELECTRICAL SYSTEM | touch screen went black a year ago , cannot use back-up cam or change the settings for my car temperature settings. warranty has expired and jeep refuses to fix, quoting $1,700 although it’s a known issue for this year vehicle. prior to screen going black it would ghost button change the stations, there were lines in the radio screen and it would randomly shut off and on when driving. | Crash: No Fire: No | Unknown |
| Nov 2025 | ENGINE | In September 2025, the vehicle was shaking upon idle when we started it. We did a test and learned it was somehow losing coolant. We took it to a mechanic who discovered it was burning coolant in the 5th cylinder. They diagnosed the issue as blown head gaskets caused by the engine being machined incorrectly by the manufacturer. This resulted in the need for a short block removal and replacement, resurfacing the cylinder heads, replacing the head gaskets, among with many smaller repairs. The cost was over $8,000 total for a manufacturing error. If left unresolved, this could have caused further mechanical issues and potentially a crash or other safety issues. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE | My 2018 Jeep Grand Cherokee suffered a sudden, catastrophic engine failure with no warning lights or alerts. Dealer confirmed the engine seized from overheating and cannot be repaired—replacement engines are on national backorder. This is my only vehicle, I’m 7 months pregnant, and I’ve been without transportation for 30+ days. This appears to be a widespread 3.6L Pentastar defect and a serious safety concern. | Crash: No Fire: No | Unknown |
| Oct 2025 | AIR BAGS,SEATS | My passenger headrest is coming apart spontaneously. It has an active airbag system. Apparently my vin is just outside a known recall range. I have called Jeep and the dealership, both stated i needed to report to NHTSA. The Jeep will be serviced tomorrow at the dealership for diagnosis and repairs. | Crash: No Fire: No | Unknown |
| Oct 2025 | ELECTRICAL SYSTEM | I have a 2018 Jeep Grand Cherokee and the screen is delaminating and now my screen is completely black. I cannot do anything on my screen which controls everything in my car. I'm unable to have my heat or air come out of anything except defrost. I had the heat on to defrost my windshield, and it kept switching to a cold setting causing my windows to not defrost. My car will randomly call people from my contacts list or if I'm on a call will place it on hold or mute. When a feature is supposed to help with distracted driving this is doing anything but that and causes all drives to be very distracting. The temperature of my vehicle is constantly switching because of the screen issues. Before my screen went completely black if I was using GPS it would randomly switch my location sometimes to a different continent again causing for a very distracting and unsafe drive because I didn't know where I was going and had to fumble around to find my phone so I could get my maps and not make a wrong turn. I'm thankful a serious accident hasn't occurred yet because of this distraction but if it does Jeep will be taking responsibility. I have called a jeep dealership and states jeep is saying sorry about you, absolutely unacceptable. There is no warning when this happens it starts out as slow minor things happening and is now extremely unsafe to drive because of the distractions it causes. Not to mention no back up camera for that extra step of safety. | Crash: No Fire: No | Unknown |
