This vehicle will not move (intermitant problem) at times when the vehicle is placed in drive or reverse. The gear shift console and dash will flash and the vehicle is rendred useless. I have to turn off and restart the vehicle to resolve the problem. Temporary fix. It keeps happening. This vehicle has been in the shop 3 times (dealing with this issue for over a year). Noone knows what the problem is. No codes are thrown. Jeep has been contacted. Several forums I have looked at online state this problem with no resolution. The problem is someone is going to be killed or seriously injured. When it leaves me stranded in an intersection, which it did, I have a major problem. A resolution has to be found. Its not allowing me to upload video. I do have video of this happening which has been shown to the dealership and the adjuster of my extended warrenty company.

2018 Jeep Grand Cherokee with 55,575 miles was parked in a parking garage all day in Brooklyn NY and when the vehicle was move to the front of the garage by parking attendants the engine started smoking and caught fire. There were no leaks, dashboard symbols or open recalls to cause the fire; additionally the car was linked to a iPhone App CarRx that can scan for any issue and no issue noted. This engine fire not only put all of the other vehicles in the park garage at risk of catching fire but the parking garage sits under a luxury apartment building putting the working and residents at risk. Additionally I commute between Brooklyn and NJ 3x a week and cant imagine what would have happened if I was driving the vehicle over the Brooklyn Bridge, on the Brooklyn Queens Express or in the Holland Tunnel during high commuter rush hour traffic. Car was checked out by a Jeep Dealership who confirm fire was not caused by any leaks or electrical issue but did mentioned it seems to have started around the engine air cleaner. The current status of the issue has been an open investigation with Jeep Corporate for going on the 3rd week with no communication or updates on status. The entire issue and fire from pulling into the garage to the when the car was moved to it smoking and catching fire is all documented on security video.

The vehicle stalled while driving on a busy road. It sounded like it couldn-€™t shift gears. It also accelerated once I tried to move it to a safer location on the side of the road. It was very scary not knowing if I could get out of the stalling situation in the middle of traffic. The unexpected acceleration upon trying to park it safely was also terrifying.

Transmission failed while driving. Had someone been behind me they would have hit me. It was towed to a dealer and through the extended warranty it was deemed a faulty transmission. There was no indication of an issue until it happened. Once the transmission failed the check engine light came on.

On our way to the grocery store, I turned onto the highway and began accelerating. Suddenly the engine shuts off and random messages pop up on the display. The "D" on the shift indicator was blinking telling me to put the vehicle into park to restart. Steering and braking were impaired as i tried to get the vehicle to the emergency lane. Numerous vehicles at highway speeds had to make rapid maneuvers to avoid hitting us. After coming to a stop and putting the vehicle in park, I restarted the vehicle. The engine light was now on and there were numerous messages coming up on the display. There were also random electrical occurrences as well, rear wiper running with switch in off position. This was a very dangerous situation. Had the individual behind us not had room to maneuver into the adjacent lane he would have impacted us for sure. This seems to be a known issue that needs to be addressed. As this incident just happened i have not a chance to contact a dealer yet. There was no warning prior to the incident. We have had no issues with this vehicle to this point save one, and I do not know if they are related or not. But randomly for a few months prior to this incident, the vehicles radio/control console would freeze up becoming totally unresponsive. It will eventually reboot itself and begin working again. Sometimes after one restart and other times it takes several restarts after varying lengths of time being frozen. The frequency of these occurrences seem to be increasing also. If this was just your radio controls it would be annoying enough, this is your control center for everything. Have not addressed this with the dealer yet as well. I will be contacting my nearest dealership this week.

Just purchased 2018 Jeep Grand Cherokee from bulk dealer. The engine consistently stalls while in drive (at red lights, stop signs, intersections) causing safety issues and near MVAs. During stall, the AC continues to blow but air is not cold. The VIN# shows no unrepaired recalls, but the vehicle is behaving exactly as described in recall U87. It still has some time on warranty but I'm not sure how to proceed here. This is certainly unsafe.

I took my vehicle to earnhardt Jeep in gilbert Arizona for the W79 egr cooler recall and only the egr valve was replaced and not the egr cooler. The recall stated that the egr cooler could crack from thermal fatigue and a new egr cooler with thicker walls would be installed. This issue if the egr cooler cracks can cause coolent to go into the air engine intake and cause a fire. The valve does not have coolent going through it so I do not know how this can be a complete fix. The vehicle had the valve replaced 4-7-2021 and I returned the vehicle 5-5-2021 withe the mill light on with the same code. Car still in the shop. Fca says the current remedy is valve replacement and not the egr cooler. This does not seem logical and I need NHTSA help to resolve this issue so my wifes vehicle is not a future fire hazzard.

After starting my car I went in my house to get something. My car slipped into reverse and rolled down my lawn across a busy street and hit a tree. The emergency braking system did not engage. I was able to drive the car back to where it was parked. I then tested to see if I could have accidentally put the car in reverse when I got out it. It began to roll in reverse and I wasn't touching the gas. I could not have gotten of the car if were in reverse because it would have been rolling. Apparently when the car is in a parked position it can slip into reverse.

After wide open throttle acceleration, vehicle continues to accelerate even after letting off of throttle. Had to immediately depress brake to its maximum capacity to slow/stall the unintended rapid acceleration. It has duplicated this behavior twice in the last 100 miles. The Jeep also indicates an error message regarding electronic throttle control error. Once again uncontrolled rapid acceleration after wot!

Car would not shift out of park and check engine light came on at same time. I was parked in the post office parking lot and this happened when I started it. Had it towed to dealer. I am told I need a new electronic shift module that is not covered under the power train warranty as fca does not consider it part of the power train.

After a cold start (even in warm weather), when shifting from 'park' to 'drive' the transmission shudders momentarily and shakes the whole vehicle. It does not do this when the engine is up to normal operating temp, or if you wait 10-15 seconds before putting it into drive. I have not had this problem with any other vehicles I've owned.

The upshifter paddle driver control on my Jeep srt trackhawk, along with many other 2010+ fca vehicles equipped with paddle shifters, performs the opposite function (downshifting) when vehicle is in motion- causing the gears to lower one or more, the engine to rev up, the engine to engine-brake, and ultimately the weight of the vehicle to shift aggressively to the front unintentionally.

I pulled into my driveway and put the vehicle in park and as I got out it began rolling backwards. I tried to get turned around and back in or grab the emergency brake but the door knocked me down and the Jeep drove backwards about 150feet and hit a tree. 3weeks for repairs and I heard about the Cherokee recall for transmission issues and this seems like what happened to me.
