    My daughter that is [XXX], her in the passenger seat, me driving were traveling down a street. I slowed to enter a turn lane going maybe 10 mph and heard a loud bang. I said "what was that noise." I glanced at my daughter she looked dazed and said "I don't know but something slammed into the back of my head." I pulled in where we were going and looked to find the head rest was popped open behind her head. There were no bumps, no impacts and not even high speed. This headrest mechanism literally deployed for no reason slamming at high speed into the back of her head and neck. I stopped called Mopar and made a complaint because it was right at 5pm and dealers were closing. She was slurring speech, dazed and repeating herself. Took her to the urgent care that sent me to the ER out of concern. They told me she may need head and neck images. The doctors and staff were so confused as to what I was even talking about. I showed them photos so they could see the situation. I was in the ER with her for 5 hours. She has a concussion. THESE HEADRESTS ARE DANGEROUS AND JUST INJURED A MINOR. WHAT DO YOU MEAN WE ARE NOT CALLING FOR RECALL. THIS ISNT JUST ABOUT EQUIPMENT REPLACEMENT. THIS INJURY COULD HAVE BEEN WORSE AND THERE IS OBVIOUSLY SOMETHING FLAWED HERE. I HAVE SEEN MANY OF THE SAME STORY. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    Headlight beams do not function. Beam lights come on upon starting car then turn off moments after. Then I am driving done the street in complete darkness. I have taken the Jeep to the dealership of purchase ( Elmhurst Chrysler/jeep/dodge Elmhurst Illinois 630-834-8000 ) 4 times over several months. They have confirmed the problem. Two days ago they had me replaced the battery. There was NO messages or other warnings that the lights have failed.

    I was backing up my trailer and placed the jeep in park and set emergency brake while on an incline. I got out of the jeep and the vehicle proceeded to roll away approximately 3 feet. I jumped back towards the drivers seat to press the brake to stop it from rolling down the hill

    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.

    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.
