ENGINE
1. The issue involved the engine and emissions system, specifically a cylinder 3 misfire, accompanied by illumination of the check engine light and white smoke emitted from the exhaust. The vehicle was evaluated by an authorized Jeep dealership, which confirmed the cylinder misfire through diagnostic testing. At that time, per the diagnosis, coil 3 and all spark plugs were exchanged. This did not solve the issue. When picking up the car, check engine light was still illuminated and white smoke emitted from the exhaust. The affected components are in possession of the dealership, unsure if available upon request. 2. The engine misfire and associated white exhaust smoke created a risk of engine performance degradation, including potential loss of power, observed hesitation and stalling, which could impact the ability to safely operate the vehicle in traffic. Additionally, white smoke from the exhaust can impair visibility for surrounding drivers and may indicate an underlying engine condition that could worsen without warning, increasing the risk to the driver and others sharing the roadway. The chemical smell could also nauseate the person operating their vehicle, impeding their awareness and concentration. 3. This issue was proposed by an authorized Jeep dealership, then confirmed by two other mechanics. Dealer diagnostic records document the cylinder 3 misfire and investigation related to the check engine light and exhaust condition. 4. No inspection from manufacturer, police, or insurance representative. 5. Yes, the check engine light illuminated and the vehicle exhibited white smoke from the exhaust which prompted the service visit. Auto-start was not functioning as normal, with an error displayed on screen. Engine would sometimes stall upon start up during cold temperature days. NOTE: vehicle is currently with another mechanic awaiting an engine replacement, will upload that invoice once available.

POWER TRAIN
While driving on the highway I received a “SERV 4WD” light and also a traction control unavailable light. Other than that that the car appeared to drive normally other than I could feel the car gears “catching” at starts when I pressed the accelerator. I took the car to the certified dealer and they said it was a transfer case failure and was unsafe to drive as it could have caused the wheels to lock up. This issue is very similar to a recall for other Jeep VINs over the same production timeframe of my Jeep, although my VIN was not included in that recall. I am seeking the immediate inclusion of my VIN into the Jeep recall that exists for manufacturing defects of the transfer case.

SEATS
To Whom It May Concern, I am writing to formally report a serious safety defect regarding the Active Head Restraint (AHR) system in my vehicle. On 11/28/25 the headrest deployed spontaneously while I was operating the vehicle. Incident Details: • No Collision: There was no impact, collision, or sudden braking event that would trigger a safety deployment. • Safety Risk: The forceful deployment occurred without warning, striking me in the back of the head. • System Failure: The internal plastic bracket responsible for holding the spring-loaded mechanism failed—a documented issue in many similar Stellantis vehicles. I contacted a certified Jeep dealership and Stellantis customer service regarding this failure. They have declined to provide a remedy, repair or reimbursement the component under any "goodwill" or extended warranty program, stating that my specific VIN is not included in existing service bulletins or recalls. Request for Action: The "VIN-specific" limitation is arbitrary when the mechanical failure is identical to those in recalled units. A safety component that deploys violently without an accident is a defect, regardless of whether the manufacturer has acknowledged that specific production batch yet. I request that the NHTSA investigate this failure as part of an expansion of existing inquiries into Stellantis AHR systems. I have attached photos/repair quote of the deployed unit for your records. Sincerely,

POWER TRAIN:AXLE ASSEMBLY:AXLE SHAFT
Front passenger side CV Axle purchased from detroit axle. They confirmed on website it would fit my make, model, and year of vehicle. Once I described that they are selling this part incorrectly and they refused to change website to continue fraud sell I asked for a full refund. They denied and said I'd be deducted shipping costs. If this part would've almost fit I'd have been a risk for life on the road for myself and others. They refuse to fix this safety and fraud violation on their website.

SUSPENSION
The front air springs, struts, and air suspension compressor failed. The dealer cannot get the right front air spring because it is backordered. It appears that 100% of these components fail creating demand that the manufacturer cannot keep up with. There should be a recall at this high failure rate on a component that makes the vehicle unsafe to drive per the warning on that dash.

ELECTRICAL SYSTEM
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.

ENGINE, POWER TRAIN, 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.

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

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.

STRUCTURE:BODY, 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.

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.

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.

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.

EQUIPMENT:ELECTRICAL:INFOTAINMENT
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.
