I backed out of my garage into the driveway and stopped the car to bring in the recycling bin. I shifted into what I thought was park, released the break, and exited the car. After I had exited, the car began to move forward toward the open garage. I attempted to jump back into the car in order to stop it and sustained a serious hand injury as the Jeep's door slammed into the side of the garage and closed back upon me. Similar runaway car events have occurred to me in this car (with less dramatic consequences) twice prior, but never in 25 years before I purchased this 2018 Grand Cherokee. Some 2018 Jeep have been recalled for faulty park lock rods, so my concern is that the events I experienced have been due to the inability to achieve park. Even if I erroneously put the car in drive, it should typically have started to move forward as soon as I released the break, alerting me that the car was in gear. Instead, nothing happened for 3 seconds - this provided a false sense of security that the car was in park and worse, gave me enough opportunity to exit. This delay can be reproduced when transitioning from reverse to drive. Lastly, when the door in the Grand Cherokee is opened while the car is in gear, it simply beeps once - a very minimal and inadequate alert system.

For the past three months since labor day of 2018, my 2018 Jeep Cherokee latitude has not started on several occasions. Eventually it does start but it will always say, "cannot read key fob". I have discovered that it's worse when I use the remote start to warm it up. What's really weird is that I have discovered that when I get out of my vehicle and go to the back hatch and use the remote to lock and unlock the doors, it starts after that. Go figure. Just this week, the driver side door wouldn't shut twice within three days. The latch was stuck. Eventually, after trying just about everything I could think of like turning the vehicle on and off and locking and unlocking the doors from the inside of the vehicle, I tried using the remote to lock and unlock the doors, and then the driver side door shut properly. I don't understand why such a new vehicle purchase brand new in April of this year with less than 14, 000 miles on it would have so many problems. The dealership is picking it up again tomorrow for the third time to attempt to fix it. Last chance. If not fixed this time, I will be getting legal representation. Not sure if these are safety issues but I know that driving down the road with the door not closed properly could be a hazard. I am just wondering if something else might go wrong with it next. I am really disappointed in this vehicle to say the least!

While driving highway speeds there is a vibration between 60 and 80 miles per hour. I have had the tires replaced, rims replaced and no change in vibration. It has started since I owned the vehicle with 7 miles on the odometer till today with 9000 miles on it. The dealer claims that this is normal throughout the line of Cherokee and is just "road vibration" but talking with other owners this is not the case and they do not experience the same thing. It does tend to fade away during long left turns on the freeway but appears as soon as the vehicle straightens. Numerous attempts to get the dealership to fix this has resulted in no headway as the dealer claims that this is normal.

While driving my dash will suddenly state "service shifter" and all my gear shifter lights will be lit up. The only way I get them off is I have to pull over, stop, turn vehicle off, and restart it. This has happen in town and on the highway. This has happened now several times over approximately 4 months now. The first time being when I got my first oil change.

Panoramic sunroof exploded outward - at 5:15 am, I was just starting to get on the on ramp to the freeway. I was not up to freeway speed yet. Weather conditions were good and approx. 61 degrees. As I was driving on the onramp I heard a loud explosion that freaked me out so bad I was thankful I did not crash. I pulled to the side of the road all tires were fine. All surrounding windows were fine. I had the sunroof barrier closed so I didn't even think about the sunroof until I heard chards of glass beads on the barrier. I pulled to the side of the freeway in the dark and gradually opened up the barrier to the sun roof a little. I could see that almost the entire pane of the back part of the panoramic sunroof had shattered making a huge gaping hole. I turned the car around and went home. If it was a rock or something was dropped on it the rock still would have been there on the barrier. The sunroof literally bows upward and it cracked at the seams so you can see it has definitely blown out. This is a manufacturer defect that could have caused an accident or worse if the barrier had been open and the glass had shattered on me. It is obviously made of safety glass. The explosion was very loud and ear piercing.

My Jeep does not stay locked. I can lock the car, but if someone tries to open it, they are able to without a problem, even when the fob is nowhere near the car. All that happens is the theft alarm triggers. My car was opened by someone in a parking garage at work even though myself and the fob were not near the vehicle. The alarm went off but the person was able to open my door with no problem,

Transmission lurches when taking off from a stop also when coming to a stop and sometimes going into reverse. It's a hard lurch so stopping for pedestrians has to happen early as I'm concerned the car could hit someone. This happens frequently.

Going 65 in the highway in the middle lane, the park assist suddenly kicked in without warning and shifted the vehicle into neutral. After drifting to the shoulder, the car would not engage into drive again. The car is less than a month old.

This complaint is not specific to my current vehicle. The head rests in all newer vehicles are making those of us who are not overweight and have good posture sit in an awkward position with our heads pushed forward. This is very uncomfortable and we can't turn the head rests around because then the safety measures don't work. Please stop making the head rests lean forward.
