Two recent events, when braking in slow traffic there was sudden acceleration with foot on brake. Even with stronger and forceful brake pressure the jeep was still moving and wanting to keep going with engine revving. Had to shift into neutral and then engine quit revving and things returned to normal. I have this jeep 10 years and am very familiar with it. Never any wrecks. No medical problems. The floor mat was not interfering with any pedals. The dealership was not aware of any recalls about this problem but they serviced the throttle-body after the first incident. This apparently was not the problem as the unintended acceleration when braking occurred a second time. In googling this problem a blog mentioned this could be the jeep brake-booster which has been recalled and was replaced on my jeep 2 years ago. Google brings up this sudden acceleration as a common search but no clear answers. I know about the toyota acceleration problem in the 1990's, that they never found or admitted anything mechanical and assumed it was granny using two feet. This is absolutely a mechanical problem with my 2011 jeep. Will take to dealership but they already said they aren't aware of this being a jeep defect. I registered this complaint with jeep customer care and they said if the dealership can't find the problem to call them back and they will work with the dealership to resolve this. They worrisome thing is they will do something for $1000 and then I have this brake/acceleration occur a 3rd time and it causes a crash!

On may 28, 2016 while navigating my driveway, my car suddenly accelerated forward and crashed into the back wall of my garage. Damage was done to my home and my car. I had no control over the vehicle. Hitting the brake and trying to hit the ignition button did nothing to stop the vehicle. On another occasion, about two weeks earlier, I had parked the car at walmart, pressed the brake and the ignition button to turn it off. While in park and the engine off, the vehicle lurched forward and bumped the SUV sitting in front of me. I am now afraid to drive this vehicle! I have reported this incident to my local auto dealership and chysler corp. The damage is being repaired at my cost.

Our 2011 jeep grand cherokee has exhibited multiple instances of sudden unintended acceleration (sua). It has occurred to my wife, one of our sons who is and aerospace engineer and myself on different days at different speeds and locations. I personally have experienced it on two occasions, one of which caused a minor accident as I was backing out of a parking space, with my foot on the brake put the car in drive and it lunged forward of its own accord, there were two other people in the car and a witness outside the car who reported it just lunged and the brake lights were still on. Chrysler inspected the car, found nothing and has closed the case. I called chrysler and asked that we discuss the issue they said they found noting, fixed noting and thus the case is closed. So they are calling three people bold face liars and my concern is they did not find anything so the cause of the problem still exists and can happen again and my wife is at risk every time she gets in the car. There are over 1,000 complaints on various forums about sua instances on jeep cherokees, channel 7 news even did a segment on it a few years back. Can you please help at all on this issue? Thank you.
