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 officers 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 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 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.

After backing the car out of the garage I was going to get out to go back into the house.. I put the car (I thought) in park, my foot was still on the brake. I started to remove my foot from the brake and the car slightly started forward I realized the car wasn't in park but drive and when I went to depress the brakes further to change gears and stop the forward motion the car suddenly revved the engine, squealed its tires while pealing out and accelerating at a high rate of speed back into the garage smashing into a brick wall and my dining room. The damage to the car is over $15,000 and damage to the house is approx. $9000. I know my foot was on the brake!` my face hit the steering wheel cutting my lip. The airbag did not deploy. I have two years left on the lease and I am terrified to drive it. In all of my years of driving I have never had an accident and I have always parked in a garage without incident. I have driven everything from Yukon to Navigator and never have I had an issue like this. I see from all the posts that I am not alone. This issue needs to be addressed before people are killed.

1) collision avoidance system engages for no safety reason whatsoever. The 'brake' warning on the dash flashes, the brakes charge, and the brakes engage. I can be the only vehicle on the road and this will occur. Has been happening intermittently each and every day the vehicle is driven. Causes distracted driving, sudden unexpected stopping and unsafe performance of the vehicle putting vehicle occupants at grave risk. 2) after a period of driving time with the adaptive cruise control engaged, the system disengages for no apparent reason. A message alerting the driver to clean the lens is displayed on the dash. The lens is not dirty or obstructed in any way. This occurs each and every time the adaptive cruise control is engaged. Causes unanticipated deceleration of the vehicle, distracted driving, and unsafe performance of the vehicle putting vehicle occupants at grave risk.

I was driving and stopped at the stop sign and when I accelerated after making the stop and took a left turn on G street located on kirtland air force base my car accelerated and I lost control and when I applied the brakes nothing happened and my car proceeded to hit a parked vehicle and still the brakes did not stop the car and the only reason the car stopped was because I hit some reinforced steel cables holding something up. Four other vehicles were damages as a result of my brakes failing.

I have a 2014 Jeep Grand Cherokee diesel. Check engine light came on... took to dealer. They flashed it. Check engine light came on again. This time the car gave me a warning that it would go into limp mode in 150 miles. Took to dealer. It is parked they say its the pre-catalytic converter and it needs to be replaced. No time line on getting part or vehicle back. This limp mode is a major danger. The service manager said there were 46 "parked" Jeep waiting for the part. I regularly take my Jeep into the outdoors I could be stranded if the Jeep went into limp mode putting me in a dangerous situation.

This situation has happened 5 or 6 times between June-Dec 2014 on our Jeep Grand Cherokee summit 4X4 ecodiesel. After coming to a complete stop a service electronic throttle warning flashes on dash board. When the accelerator is pressed to continue forward there is no power and the vehicle will not accelerate forward. On some occasions the car had to be restarted several times before it operated normally again. On other occasions the car regains acceleration capability after a short 10 to 15 second delay. We have had the car in for service for this issue but the dealer found no error codes in the system when diagnostics were run. We are taking the car in for service again on 12/16/14. We have been lucky so far that we are not in the way of oncoming traffic when this has happened or that we have not been hit from behind when we are unable to accelerate after stopping at stop signs or traffic lights. We would certainly like to get this problem fixed before we are involved in a crash.

The vehicle abruptly braked when there was clearly no threat. This almost caused a rear end accident from the vehicle traveling behind me.and it truly upset that driver. Not a great situation. This has occurred three or four times. I asked the dealer to check with Chrysler and they tell me they can not find anything wrong with the vehicle.

On November 17th, after about 30 seconds driving forward, the car shifted from 2nd gear back to first gear. The car practically skidded to shift back to first. I was thrown forward in the car. Luckily, I wear my seatbelt. It would not shift out of first after that. The engine light came on. I had it towed to the dealership where I bought it. They said something is wrong with the transmission. They said they could not fix the transmission, but would replace the entire transmission. They said with a car this new, they do not have the knowledge to fixing the transmissions. They replaced the transmission and drove it 200 miles. They said it is fixed. I picked it up on a Monday, November 24 and drove it home. The next day, I had the problem again. When turning on 4 lane road (2 in one direction and two in another), the vehicle started to go across the intersection. It appeared to try to shift to 2nd, but the car stopped moving (like it was in neutral). I had to start blowing the horn as oncoming cars were coming at a high rate of speed. I could have been killed. I immediately called the dealership. They picked the car up and drove it back to the dealership. They ran numerous tests on the car and could not duplicate the problem. They called and told me the car was ready. I have severe reservation about getting back in a vehicle that I could have been killed in and drive it away when I know, the dealership knows and Chrysler knows, they couldn"T duplicate the problem and they didn"T fix anything. So, basically, I will be driving a ticking time bomb that could blow up at any time. My wife, kids and grandkids could be in jeopardy and other drivers on the road. I paid over 50K for this vehicle, only to find myself stressed out over this fact. I cannot get back into this vehicle knowing nothing was fixed and I was almost killed.

When coming to a slow brake, the brakes stutter and push the car forward. Additionally, the vehicle sometimes when driving at higher speeds (specifically on the freeway at about 60-70mph) engine revs high without kicking over. Furthermore, when slowing it has a hard time kicking down to the next gear. Transmission light has come on several times as well. When taking the vehicle in for service, they are unable to recognize any problems at all and can not fix.
