The engine stalled completely while I was at a traffic signal, preparing to make a turn onto a busy highway. Loss of power to brakes & steering since the engine completely shut down. I shifted the vehicle into park, started the engine again, shifted into drive but the vehicle would not move. Eventually (in a matter of seconds) the vehicle lunged forward and I was able to safely drive home.

To whom it may concern: I would like to formally report what I consider a critical flaw with my 2012 9jeep grand cherokee equipped with the pentastar v6 engine. I have had multiple instances of unintended acceleration by the engine in the past 45 days. The most recent event resulted in my damaging vehicle's wheel as well as nearly hitting a parked vehicle. I have 85533 miles on my car and this flaw has only manifested itself in the past 3 days (85533miles). I have contacted my local dealer concerning this issue, but have been told that in order to look into this obvious safety defect, I am required to pay for their diagnostic time. I feel that the manufacturer of a product that has such a blatant safety risk should be appreciative of being informed of such a defect, and certainly take responsibility for it. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

This jeep has remote key-less entry/engine start. The engine cannot be turned off unless the gear shift is in park. If the throttle stays open causing unintended acceleration, one cannot turn the engine off. This could result in one or more deaths and/or serious injury! If one had an accident causing the engine to rev up due to a jammed gas pedal, how do one turn it off? Chrysler customer service was contacted about this issue and their response was "the characteristic you describe, however, is a function of your vehicle's design and there is nothing that can be done to ?fix? The condition." reference number: email case number: supplied upon request. In other words they don't care about this safety issue! I have another car that can have the engine turned off, but it is a standard transmission. Madza's can be turned off while in drive with automatic transmissions. This jeep was purchased in the USA.

Preparing to back from my garage, I stepped on the brake and placed the selector in reverse. Despite my holding firmly on the brake, the jeep grand cherokee moved backwards as if sliding on ice. It collided, at a slow speed, with a car parked opposite on the driveway. While continuing to apply the brake, I moved the selector into drive in order to pull forward away from the other vehicle. The jeep lunged forward with the front tires remaining stationary and sliding along the ground. The vehicle crashed into the stone column between the two garage doors. The car was damaged to the extent of at least $5,700. There was damage to the building and to one of the garage doors. I am fearful of driving the jeep grand cherokee even after repairs are completed. If I had been in a parking lot or at a stop light there could have been severe damage or injury from this incident.
