My wife and I were driving down the road in a neighborhood and her body just shot forward like somebody shoved her from behind. The headrest shot out of place and hit her in the back of the head forcing her forward. She had some neck pain for a little bit but nothing serious. Thankfully it was the passenger seat and not the driver seat. I couldn't even imagine if one of us were driving on the highway and having this happen to the driver.

Previously entered complaint regarding cold throttle/turbo lag of 3-5 seconds which is dangerous for pulling into traffic and almost causing accidents but this is not limited to cold vehicles. The lag is shorter but evident when warm. I have had several incidents of hitting the lag while trying to turn in an intersection and there is a "flat spot" lag of 2 -3 seconds. Pressing the gas pedal in stop and go traffic can cause a lag then surge forward. I have almost hit the car in front of me several times and had difficulty switching lanes because I get the nose of the vehicle turned into another lane then it does not move causing near collusions then surges forward. This is extremely dangerous and I am beginning to be frightened of driving this vehicle for even the shortest of times.

Driving down the interstate when suddenly the driver's side active head restraint deployed and the headrest shot forward towards the back of my head. Luckily, I was seated forward, looking in my mirrors to change lanes so it did not hit my head. Taken to the jeep dealership and they stated that the plastic clips inside the headrest seemed to have broken and caused the headrest to deploy unexpectedly.

While decelerating, 8hp70 automatic transmission experiences severely delayed downshifts with hard jerking from 3rd to 2nd and from 2nd to 1st gears. Downshift from 2nd to 1st is most severe, often causing vehicle to lunge forward after having already come to a complete stop. This issue essentially occurs every time the vehicle is driven. It has been to a jeep dealership twice for service, but they cannot fix/identify the problem.

I have a serious safety issue with my 2015 jeep grand cherokee. I have brought it to the dealer for this problem more than once and they are not able to identify any issues with the vehicle. They have not been able to replicate my experience. In short on a few occasions while driving at low speed the vehicle seems to change gear and accelerate. I would best describe it as a surge. This past saturday (12/08/18), while coming to a stop a three way intersection my jeep accelerated without warning. I already had been depressing the brake when the surge happened and since I have experienced this before I was able to bring the vehicle to a stop. I was lucky I did not accelerate into two way traffic. I was not so lucky in december of 2017. I was stopped at a traffic light (my wife and adult son were in the car to witness this). When the light changed, I took my foot off the brake and my car suddenly lurched forward. I jammed down hard on the brake but my car made contact with the car in front of me resulting in a fender bender. It could have been worse. I experienced this phenomenon one other time while driving along and stopping at a light. Fortunately, there were no other vehicles nearby. As you might imagine, this has destroyed my confidence in this vehicle. I am afraid that this will happen again and may cause a more serious accident!
