When I attempt to accelerate quickly, the car seems to shift into neutral (although it doesn't display that it is in neutral on the screen) and will not accelerate. The engine still revs when I push the accelerator, but the car acts as if it is in neutral and the car will not accelerate. This problem has occurred several times in my vehicle, and each time I have been traveling at speeds of greater than 40 mph and it has occurred when I have attempted to accelerate quicker than normal, such as when I am merging on to the highway. I believe it is a problem with either the transmission or the computer that operates the transmission.

Jeep accelerated on its own from 40-67mph I tried to press brake to stop car but it didn't work since the Jeep kept on acceleraiting. Tried to shift to natural and ride it out but it wouldn't shift it was stuck on accelerating. Killed the engine since the brake wasn't stopping the car since it kept on trying to accelerate and since I couldn't shift to natural. Jeep has had my car for 2 days and can't find anything wrong with it and claim they have never heard of that issue which is the reason I'm reaching out here.

Adaptive cruise control and collision avoidance did not work properly, and resulted in a collision. I was driving on a highway, relying on the adaptive cruise control and the automatic breaking, a feature of collision avoidance. There was a slow down in traffic, and although the system slowed down and applied break, it did so too late to stop car. As I got too close, I applied steady pressure on the break, but I still hit the car in front of me, who then hit the car in front of them. No significant damage to either of the other cars, and mine has minor cosmetic damage, and the adaptive cruise control is now not working properly. Could have been significantly worse. Makes me really question the potential for self-driving cars.

While vehicle was in motion on the highway the engine shut off. My wife was driving it with our 4 year old daughter in the backseat. At that time the vehicle lost power steering. She called me in a panic. I called the Jeep dealer who came and towed the vehicle in to the service department. The same thing happened while the Jeep was in the shop at California superstores in valencia, ca. They called me several times to come and pick the car up because they could not figure out what happened, but that there was not a "fix" for it. Due to concerns for my familys safety I refused to pick the car up and called Chrysler who told me not to pick the car up, that it was dangeous to drive it. The next weeki was again told to come and pick the car up, this time by both the dealer at California superstores, valencia, ca and by the corporate people at Chrysler, and told there was no fix for the problem. The car just randomly shuts off while driving it. I opened a claim withchrysler Corp. About the car stalling out but have not heard back about any fix or recall. The car is unsafe to drive and I am not receiving any help from the dealer or Chrysler Corp. I paid almost $38,000 for the car and do not even want to drive it or have my family in it due to the possibility that it could stall again (it has happened several times), the steering go out, and cause an accident harming us or other drivers on the roadways.

Forward collision warning (fcw) occasionally comes on without reason in city traffic, interstates, and country roads (no traffic or obstructions nearby) and at various speeds causing a "brake" warning signal and sometimes, not always, actually causing the vehicle to brake. Related to the fcw problem is a warning signal that frequently appears that indicates the adaptive cruise control/fcw are unavailable. Vehicle has been in shop numerous times and except for one time that the dealership found a part missing, the dealership continues to indicate they cannot duplicate the problem. The problem remains on-going and has not been resolved. The date of occurance below is the most recent event with the "brake" warning.

The contact owns a 2014 Jeep Grand Cherokee. While driving at approximately 50 mph, the vehicle jerked and independently slowed down after an unknown warning indicator illuminated. The contact stated that the accelerator pedal failed to respond. The contact had to hit the gear shift. The engine revved and went into sports mode. The contact continued to hit the gear shift until the vehicle shifted back into gear. The failure recurred on several occasions while driving at various speeds. Upon purchasing the vehicle, they were told that if the vehicle independently shifted into sports mode, they should push the gear shift back to change the mode. The vehicle was taken to the dealer but the failure was unable to be determined. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 7,000.

Our SUV is equipped with collision avoidance and adaptive cruise control. The vehicle has repeatedly and without cause either alarmed or in some cases slowed to avoid a collision that is not eminent (I.e. along a straight section of highway with no vehicle or object within sight of the car). The system has provided multiple false alarms and we have not been able to determine a pattern or trigger. Additionally the car reports at times that the acc is inoperable and then moments later the fault message disappears. The car has been taken in for service to address. To date the dealer has been unable to replicate the problem and Jeep is unwilling to replace any parts or acknowledge the problem until it is replicated for them to be able to witness.

Vehicle is an eco-diesel model. Engine check light came on and the vehicle abruptly lost power as we accelerated away from a stop light. Initially the vehicle would not go over 20 mph. It gradually allowed us to get up to about 50 mph, but with noticeable vibration. Then a notice displayed on the information center telling us to service the electronic speed control. Took it in the next day and the dealer said we were driving with left foot on the brake and right foot on the accelerator causing the computer to be confused. Same problem happened a second time a week later. This time it gained enough power to get us up to 40 mph and home. We then had it towed to the dealer. Not sure what they did to fix the problem but it has not happened since, however the engine check light has come on again 3 different times. Each time the dealer says that they don't know what is causing the problem. The first two times the engine check light came on the dealer said it was ok to drive until they could schedule service. The third time we asked the dealer to contact Jeep headquarters for technical support. Corporate Jeep said not to drive the vehcile with the engine light on, that it could cause serious problems. On-line research and discussion with other local owners of the same eco-diesel model suggest this is a systemic problem with potential safety issues.

While travelling on open highway with no vehicles in front of me, the adaptive cruise control will dramatically slow down as if it's detecting a vehicle in front. This was reported to the dealer who responded that they would need to take my vehicle home on a 20 mile trip, in rush hour, with cars around them. Unless I let them take my vehicle on a long highway trip, in the early morning hours, this will not be re-produced. I said no for obvious reasons. This is now documented with the dealership and Chrysler.

While driving with the adaptive cruise control engaged the vehicle braked itself hard extremely slowing the car down on the highway. There were no cars in front or in other lanes when this happened. Had a car been following me I would most likely been rear ended.took the vehicle to the dealer and, after checking out the vehicle, they indicated that they could not duplicate the problem, that the software was up to date, and that the acc system is "working as designed." This is a major safety issue that under different circumstances could have resulted in a serious accident with injuries or worse.

I was driving down the road today and my turns signals got stuck on again! this isn't the first time this has happened and this is not the first complaint I have filed. I have had my 2014 Jeep Grand Cherokee back to the dealership service department four times for this same issue. I have been told all four times that they cannot duplicate the problem. I have two videos of my turn signals getting stuck on and my dash flashing and reading the incorrect speed but the service department continues to tell me that they cannot duplicate it. Well, today there was almost an accident because of it. My turn signals got stuck on and another car pulled out in front of me and I almost hit them, they obviously thought I was turning, which I was not but yet again my turn signals were stuck on. Fca is fully aware of this issue. I have called them numerous times but they have no solution for me. I feel completely unsafe in my Jeep Grand Cherokee and it is just an accident waiting to happen.

I was driving home from work on 7/5/15 and my dash started flashing. It was reading the incorrect speed and mileage and I could not get it to stop. I have contacted my Jeep dealer service department and fca about this. This is not the first time this has happened. I have been complaining about the speedometer, odometer and the dash flashing since August 2014 but everytime I have taken it in for service I have been told that they cannot duplicate the problem. Well this time I took a video of it happening. My speedometer would read my traveling 30mph then all the way down to 20mph and then all the way up to 40mph all in my 22 second video! I have no idea how fast I was really going and the flashing is very disstracting to try and drive and pay attention to the road. I have told fca for almost a year now that I do not feel my Jeep Grand Cherokee is safe and I continue to have more and more electrical problems with it even after the recalls were completed and I have yet to hear anything from them. I called and complained so much to them that they asked me to stop calling.

I was driving approximately 40 mph on w. maple rd in troy, mi in the middle of the afternoon on February 18, 2015. There was minimal traffic on the road and no one in front of me in my lane or the lane next to me. Suddenly, my dash lit up to brake and the car started braking on it's own. It happened so quickly that I wasn't even sure what it was. It happened again about a mile down the road. Again the system applied the brakes and the warning word brake flashed on my dashboard when there was nothing near me. It happened quickly and then the car went back to normal without me doing or changing anything in the car. I brought it to the Suburban Chrysler Dodge Jeep Ram dealership in troy and they said they were not able to recreate. No codes were activated in the computer and there were no service bulletins about it so there was nothing they could do... I took the car home and the same thing happened again to me five days later driving at approximately the same speed. This time the dealership kept the car longer, drove it 119 miles, used the miller tool kit to align the camera and still found nothing wrong. The following week, it happened again and I returned to the dealership. This time they replaced the front sensor and bubble aligned. The only thing that the dealership found was that on one of the test drives they couldn't get the acc system to work at all and still no reports showed up on the computer. The next test drive all systems were working, again no report on the computer of the change. The dealership still could not duplicate the problem but they thought that they fixed it.. in may, it happened again. It occurred while I was merging onto the expressway traveling at 63mph. I returned the car to the same dealership and again it was returned to me without being able to diagnose or fix the problem...updated 07/21/15

My daughter was parking her 2014 Jeep Grand Cherokee outside of a retail store. As she slowed and pulled into a parking space, the Jeep suddenly surged forward, jumping the curb, crossing a sidewalk, going through a small grass median, and into a different area of the parking lot. The police report, Oklahoma city police department report, case number 15-redacted, accurately records the "surge." The officer's conclusion was driver error. Through research I have found numerous similar complaints concerning 2014 Jeep Grand Cherokee. I called the service manager for the Jeep dealership where we purchased the vehicle. I told him about the accident and that when the Jeep came in for repair, I wanted the accident data preserved. He told me the only data that he could obtain was Jeep's proprietary information, which I could not have. A representative form my insurance company is adamant that we, as the owners of the Jeep, have a right to any information captured by the Jeep's systems. However, the insurance company had no way to obtain that information when they appraised the damage to the Jeep. I need help in obtaining the data by someone outside of Jeep who can access it, or help to compel Jeep to provide me with the information, hence this online submission.

Driving through the eisenhower tunnel the brake warning system activated. The brakes did not engage. I have had this Jeep for over a year and have driven through this tunnel over 80 times and now whenever driving through the tunnel this brake warning will flash. This has occurred approximately 16 times now. This warning is now going off on the open interstate and secondary roads. The adaptive cruise control stops workings after 15-20 minutes. This has been into two different dealers, only to tell me the lens was dirty. Within 20 minutes after leaving the dealer (who cleaned the sensor) the system stops working and says to clean the sensor. No snow or water was driven through prior to the message being displayed.
