Cylinder Misfires OBD-II code P0303 Engine Overheats after changed thermometer Fuel in the coolant system Coolant leaking from exhaust
Air bags, May 27, 2026
While driving my Jeep Grand Cherokee, the front passenger headrest suddenly deployed forward with a loud popping/exploding sound. There was no collision, no impact, and no warning before it happened. Fortunately, no one was sitting in the passenger seat at the time. If a passenger had been seated there, the headrest could have struck them in the back of the head or neck and potentially caused serious injury. This appears to be a dangerous safety defect involving the Active Head Restraint system. Based on information I found from other Jeep Grand Cherokee owners reporting similar failures, the issue may involve a faulty plastic bracket or internal component in the Active Head Restraint that can fail under pressure and cause the headrest to deploy unexpectedly. Other owners have reported injuries such as head, neck, and concussion-type injuries from similar incidents. I am concerned that this failure happened during normal driving conditions and without any crash or trigger event. This creates a serious risk to vehicle occupants and could also startle the driver, potentially causing a crash. I am requesting that NHTSA review this issue and determine whether my vehicle is affected by an existing recall or whether additional investigation or recall action is needed.
Air bags, Seats, May 22, 2026
The active head restraint on my driver seat deployed and pushed my head forward suddenly. I could not push my head back into position. This happened while driving on the evening of May 3. I have a 2018 Jeep Grand Cherokee Laredo. I was not able to reset the head rest position. I took the vehicle to the dealership. They said that the whole headrest needed to be replaced. It could not be reset because the molded plastic piece was degraded. From a search online this appears to be common in the 2014-2018 Jeep Grand Cherokee with active head restraints. Even though this is a failure of the equipment, and other Jeep Grand Cherokees from 2014 -2018 received a 10-year extension on their head restraints, the dealership and Jeep Customer Care said that my vehicle is not covered. Nor will they let me buy a seat from them that does not use the active head restraint. They said that because My vehicle's VIN specifies a vehicle with active head restraints, they cannot sell me otherwise. I will not be comfortable driving this vehicle again with an active head restraint that could randomly fail and punch my head forward while I am in rush hour traffic. I believe this is a safety risk as it is disorienting to not know why your head is suddenly pushed down and forward while you are driving at 45 mph. Distracting the driver in such a way endangers the driver, passengers, and other vehicles' occupants on the same roadway. It throws off your view of the roadway and your mirrors. There were no warnings ahead of time.

On 5/72026@app 3:14pm after picking up one grandchild, and at a stop light on the way to p/u the other, the Jeep without warning just disengaged when the gas pedal was depressed, but to no avail. While frozen, the dashboard may have displayed something that was not noted in the panic to get the car moving! The internal panel was still illuminated, however the car would not move forwards although still in "Drive" with nothing having been switched, shifted or toggled except engagement of the brake to stop at the traffic light. The Jeep had to be placed in "Park", the starter button pressed, then pressed again to completely restart the vehicle. This was a potentially huge safety issue with many cars around us honking & rushing to pick up their own children, yet fortunately no one ran into us with our precious little rider!

There are parts in the engine that malfunctioned and have caused fluids to leak into the engine. This is causing the engine to fail and requiring replacement. This issue started last year for me personally. The car has been to 2 mechanics and they both have diagnosed the issue , and to fix it requires full engine replacement . It’s a safety issue because the engine can lock up and stop the car.

I recently purchased a 2018 Jeep Grand Cherokee and began experiencing serious issues almost immediately after taking possession of the vehicle. The vehicle has stalled unexpectedly while driving on multiple occasions, including during active driving conditions. It also has difficulty starting and has shut off without warning. The vehicle has already undergone multiple repairs within a short period of time, including work related to the radiator, spark plugs, and ignition coil. Despite these repairs, the issues continue. This creates a significant safety concern, as the vehicle becomes inoperable without warning, especially during daily highway driving. I rely on this vehicle for transportation, and it is currently unreliable and unsafe to operate.

Twice I have been driving on the highway at 60 mph and the transmission had suddenly shifted into low gear and subsequently went into limp mode. The dealer is unable to find an issue with the vehicle. There were no warning lights, before, during, or after. After I pulled onto the shoulder of the road and turned the Jeep off and turned it back on it operated normally.

The contact stated that while unloading groceries out of her vehicle with the vehicle in park(P) and the engine on, grayish-white smoke began to emit from the vehicle without warning. The contact turned off the vehicle and checked under the hood, where she saw flames in the engine. The contact then ran to the fire department, which was nearby, and informed them of the fire. The fire department arrived at the scene with a fire truck and extinguished the fire. The police department also arrived at the scene, and a police report was filed. No injuries were reported due to the fire. The vehicle was destroyed as a result of the fire, but was not towed. The dealer or manufacturer had yet to be notified of the failure. The vehicle was not repaired. The failure mileage was approximately 74,000.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the “Service air Suspension” warning light was illuminated. In addition, the contact stated that the headlights independently turn on and off, the doors independently locked and unlocked, and the radio independently changes stations. In addition, the contact stated that the failure caused the headlights to burn out prematurely. The vehicle was taken to the dealer; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact was later informed that there was moisture in the wires. The contact was informed that the moisture had been cleaned from the wires. The contact was informed that the vehicle was repaired. The contact disagreed with the diagnostic test and the repair. The contact stated that the failure was a known failure with the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000. The VIN was unavailable.

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.

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.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while driving at 20 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle stalled. The vehicle was restarted, and a short distance later, the failure persisted. The contact stated that there were several attempts to restart the vehicle. However, the failure persisted. The message "Shift to P then Desired Gear" was displayed. The contact continued to drive and arrived at the workplace. The contact stated that prior to the failure, the vehicle jerked while driving. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 25V011000 (POWER TRAIN). However, the VIN was not included in the recall. The manufacturer was notified of the failure. The failure mileage was approximately 44,000.

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,

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.

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.

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.
