While driving a message of service shifter displayed and vehicle went like on park mode but in D shift. Car was in motion and became stationary. Shift lights came on. All wheels were locked, service engine light on. Turning car off and back on didn't help. I was unable to move the shift from D to any other shift. It was very scary as I was on heavy traffic road, unable to move the car in the middle lane during work rush hour. It had to be towed to the dealer, tow guy had issues getting into the flat bed as the wheels were fully locked. Awaiting a diagnosis.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that every time the vehicle was in operation and a turn was made, the vehicle decelerated and lost power. Also, the front wheels and steering wheel seized. The contact could not turn the vehicle due to the stiffness of the steering wheel. In addition, the engine leaked oil and the electronic throttle, check engine, and stability control warning indicators illuminated. The vehicle was towed to North West Dodge (9616 northwest fwy, houston, tx 77065, (281) 720-1128) where it was diagnosed that the oil needed to be changed. The vehicle was repaired multiple times, but the failures recurred. The manufacturer was not made aware of the failures. The failure mileage was 39,680. The VIN was invalid.

The vehicle was stopped and placed into park with the engine running. I exited the car and it accelerated in reverse in a fast speed and struck a parked vehicle. I was caught behind the open door in panic and was very fortunate that I was not knocked down and run over by the wheels.I am adamant that the transmission was placed into park and not in reverse. I was shocked at how fast the car was traveling. The incident was witnessed by my husband and my brother in law. My husband later talked to a man that was nearby and was told that he had the exact same car and year and that the same thing happened to him. An investigator was sent out and determined that there was a faulty part in the vehicle. The man lived in the state of Colorado which is where it happened. My husband forgot to get his name. This happened in an rv park on flat terrain, private property.

2018 Jeep Grand Cherokee trackhawk throttle stuck open and began accelerating after removing foot from gas pedal. This issue is not related to the floor mat recall as I have already had the recall performed on the vehicle by the dealership. This could have caused a serious injury or death. I had to press the ignition to turn the power off and slam hard on the brakes to stop the vehicle from continuing to accelerate.

Had several issues with this rented vehicle still running after pushing button to stop vehicle when parked. Family members told me 'your car is still on' at least 3 times. Had issues when stopped at an intersection. The vehicle seemed to die & was very delayed when starting to go again-required more pressure on gas pedal than usual. Had issues while filling the vehicle with fuel. Several times the pump would cut off (approximately 10 times) indicating that the tank was full when I knew it wasn't. had a severe issue resulting in damage to the vehicle & the aloha island mart at 50 pakaula St. Kahului, hi 96732 gas pump. I stopped to fuel up in order to return the rental vehicle to budget rental car (865 w mokuea pl, kahului, hi, 96732), I put the vehicle in park, pushed the button to stop the vehicle to turn off the motor. Exited the vehicle to get the credit card out of my purse which was in the back on the floor board in a beach bag I saw that the vehicle was rolling back. There was no slope to the parking lot, it was level ground. I jumped back in the vehicle with left foot outside the vehicle and put my foot on the brake to stop it, it went out of control backwards. Thankfully I got my left foot in and had to use both feet on the break to stop the vehicle. Put the vehicle in park & turned it off again.the door & driver front quarter panel sustained severe damage from hitting the gas pump which also received damage. Although the pump was in workable condition once the vehicle finally started & was moved. This could have resulted in severe bodily damage to myself as well as more vehicle & bodily damage if someone had been behind me at the next pump. Needless to say I was terrified, shaking uncontrollably & the thought of what could have happened. After reading the complaints & recalls on the Jeep Grand Cherokee I feel this one should be added.

This vehicle lacks any kind of utility for positive engine shutoff confirmation, and/or a warning indicator when the key fob is separated from the vehicle. It is very easy to accidentally park and exit this vehicle and leave it running. It has happened to me four times in the 18 months that I've owned it. Two of these times the engine was left on while parked for more than an hour. This is obviously a huge safety and emissions issue. Specifically, because no key removal is necessary, it is easy to push the button to turn off the radio and subconsciously believe that you've turned off the vehicle. Car engines are very quiet now, and when exiting where there is even nominal ambient noise, you may not hear the vehicle running. At minimum, I believe the key fob should have a sensor to know when it is more than say 20' away from a running vehicle and it should warn you with loud audible alarm. A secondary option would be to have a mobile app or network connected service that could send a text or email that the vehicle has been idling in one place for more than xx minutes.

When stopped at a light car stalled, start stop pressed after car places in park and car ran. Automatic off error lit up on screen in yellow and remained on despite turning off automatic off. Then when came to another stop at a drive through, car was placed in park and the car again wouldn't take off after returning to drive until stop start was pressed again even though auto off was still turned off.

The vehicle is brand new and a few months after purchasing it the vehicle would shut down electrically (twice while driving) and the steering wheel and brakes would lock up. Since purchasing the vehicle in November of 2017 I have had 4 to 5 separate occasions where the vehicle had to be towed to the dealership in Jeep/Chrysler in libertyville, Illinois. I made verbal complaints after the second and third time. I was told after the last issue the problem was resolved and no more issues would occur, about 10 months later the issue has occured once again for a fourth time. I have son that I pick up on the weekends which requires me to drive on the highway. My fear is that the electrical will go out and my son will be hurt in a car accident due to the steering and brakes locking and no way to stop the vehicle safely. The occasion where is was driving the vehicle starting going haywire, the dash lights were flickering and different signs were coming on and the brakes became very hard to press until I couldnt any longer and the steering became really hard to move until it eventually locked as well. On 9 April 2019, the last of the few issues that has happened to this vehicle it was stationary and it wouldnt start and the electrical started acting up with the dashboard giving me the same messages from the last few times that the situation had occurred.

My 2018 Jeep Grand Cherokee just accelerated by itself up a sidewalk at a parking lot and ran into the pillar of a building. I then put it in reverse and it accelerated into a car parked beside me. The front axle snapped completely even though the impact was not tremendous. The air bag did not deploy. This vehicle has all kinds of impact sensors and usually brakes on its own even when it senses a leaf from a nearby bush and none of that worked. This happened just yesterday and I'm at a loss as to what to do. I cannot believe my internet search has yielded so many similar stories!

The Jeep will restart after pushing the start/stop button. The RPM gauge will drop to 0 and then it will restart again and all the lights on the dash come on again like when you first start it. Sometimes it's right away and sometimes it takes sometime. I have had it in the dealership and they couldn't replicate the issue. There has been numerous times that it has restared and ran for a few hours in a parking deck. I am worried that if I park it in the garage the carbon monoxide might poison our family.

After having my Jeep brand new from the dealer roughly about two weeks after purchasing the check engine light turned on. We bought our Jeep from autonation in spring, tx. We live in galveston county so when it turned on we took it to autozone for the free code check - the code read was P20E8 and it just said emissions code. No specific readout was available for the code detected. The exact Jeep we own is a 2018 Jeep Grand Cherokee serling edition ecodiesel. We did notice that the def fluid was not properly filled to the full level upon the purchase so figured it could in relation to that. We drove back up to spring to the dealer and told them the issue and they said ok got us in a rental and then would call us as soon as it was ready. Once we picked it up it we asked what was the cause for the code and the technician said 'oh well it was nothing - just something that we forgot to turn off'. on the way home the check engine light again comes back on the dash. We stop by another Jeep dealer in the way home and inquired with them what they thought it might be and they said 'that whatever the dealership told you cannot be true'. then bill or service or receipt said check engine light P20E8 was found def pump low pressure fault is stored, found tank low with less than 2 inches of fluid in take, found vehicle was not topped off when purchased, added def to tank and cleared codes and verified proper def fluid pressures at injector. The light remains on two days later and now a message pops on my dash and said 'def system problems see dealer'. normally I would not be so upset but this a brand new car the dealer (not mentioned) was not exactly helpful dropping off or receiving the vehicle back with any kind of helpful information. I love my car and just want to make sure it can be properly fixed so I hopefully do not have to worry about my safety or the integrity of my car.

This SUV has the energy efficient shutdown/restart feature. After being stopped at a traffic light, I re-engaged the engine/transmission by lifting my foot off of the brake and began pressing the accelerator. There was very little power to accelerate, you could hear the grinding and pulling of the engine/transmission but only a little power. I put on the emergency hazard lights, looked around the dash for messages and verified that the gear was indeed in drive. I continued to press the accelerator to move the truck out of traffic. I made it to a driveway where I could pull off of the main street and not block the morning rush hour traffic. I put the truck in park, looked at everything again (no warnings or error messages) and put the truck in gear and it moved as it was supposed to do. I made it back to the street, went a short distance (less than 2 blocks), started to go up a small hill and the no power issue happened again. I was less than a block away from my destination, so I S-L-O-w-L-Y made it to the top of the hill. I parked in my office's garage, reported to work and contemplated what to do. I have had this truck since the end of June and it has only 1,100 miles. I will be dropping it off/towing it in to the dealer repair shop tomorrow. This is dangerous and not acceptable Jeep!

While driving around a curve, steering control went out and traction control kicked on. This caused an inability to properly control the vehicle. Traction control pulled vehicle into the side of the road and caused a minor accident.

Complained of an oil leak(oil marks on the garage floor and cardboard place to verify) prior to 7500 miles. Dealership unable to find the oil leak the first time. Took it back 1 week later to complain about an oil leak. Dealership placed dye into oil to find the leak. Leak was found to be the seal between the engine and transmission. When dealership went to replace seal, they stated the block was cracked due to "being machined during the assembly". now waiting for a new engine to be replaced on a new vehicle of 4 months. Ouch!
